According to weather forecasts, from February 1st to 6th, Hubei Province will experience the most powerful cold wave of the winter, with low temperatures, rain, snow, and ice. The average temperature across the province is expected to drop by 6°C to 10°C. This severe freezing weather will pose a significant threat to the normal growth of tea plants, particularly young ones. Precautionary measures should be taken to minimize the impact of extreme freezing conditions on tea fields and ensure the production of spring tea next year. Influence of Low-Temperature Freezing Weather on Tea Production Severe freezing weather poses a significant threat to the normal growth of tea plants, especially young ones, potentially leading to reduced yields, decreased quality, and even plant death. Measures to Prevent Frost Damage in Tea Plants 1. Covering for Frost Protection For mature tea plants in high-altitude areas, non-woven fabrics, ground films, or shade nets can be used to directly cover the canopy, with better results achieved by erecting a shelter 10cm to 20cm above the canopy. Covering with rice straw or crop stalks provides even better protection against extreme cold. Covering materials should be removed when temperatures rise. 2. Spraying Anti-Freeze Agents For mature tea…

Puer tea does indeed improve with age, primarily because the chemical components within the leaves undergo carbonization over time, significantly altering the taste. Once it has been aged for 15 to 20 years or more, the brewed tea becomes even more enjoyable. However, it is not recommended to store the tea indefinitely, as this can cause the loss of its nutritional components. Is Puer Tea Better with Age? The saying that Puer tea improves with age comes with conditions. Not all Puer teas benefit from extended storage. The longer aging process enhances the aroma and flavor, making the tea more complex and desirable. As a result, older Puer teas are often more expensive. However, there is an optimal period for aging, during which the unique qualities and aged aroma develop. This transformation is due to post-fermentation processes that occur in storage, where compounds like polyphenols, amino acids, and sugars change, leading to an ideal color and aroma. If stored improperly or for too long, the quality can deteriorate, and beneficial components may degrade or oxidize, losing the tea's characteristic flavors. Conditions for Puer Tea to Improve with Age 1. Good Raw Material Sunlight, soil, climate, and temperature fundamentally determine the…

With the drop in temperature, the growth of the above-ground parts of tea trees slows down gradually while that of the underground parts remains relatively active. Applying base fertilizer in autumn can improve the efficiency of fertilizer use by the tea trees and contribute to enhancing the quality and yield of spring tea the following year. Therefore, it is essential to apply base fertilizers scientifically to tea trees in autumn. I. Principles of Fertilization 1. Organic and chemical fertilizers should be used in combination, with organic fertilizers replacing part of the chemical fertilizers, and base fertilizers should be applied deeply; 2. Maintain a suitable nutrient ratio. Based on soil fertility conditions and tea yield, determine the nitrogen fertilizer amount and enhance the combined application of phosphorus, potassium, and magnesium fertilizers, paying attention to the supplementation of sulfur, boron, and other nutrients; 3. For tea gardens with severely acidified soils (soil pH < 4), measures such as applying lime, soil conditioners, or increasing the application of mature livestock manure can be taken to gradually improve the soil; 4. Combine scientific fertilization with green cultivation techniques that increase yield and efficiency. II. Methods of Fertilization 1. Timing of base fertilizer application: It…

Nursery management significantly influences the survival and transplanting rates of tea seedlings. Different ecological and physiological factors at various stages of development require distinct management approaches, depending on when the cuttings were taken. I. Development Cycle of Tea Seedlings When using short-shoot cuttings, the process from planting to developing a standard-compliant tea seedling can be divided into two phases: the pre-plant stage where the cutting is establishing itself, and the phase where a complete plant develops into a viable seedling. The survival rate during the first phase is critical in propagation techniques. Summer and early autumn cuttings have longer growth cycles and larger growth volumes, which often result in a significant number of weaker plants due to competition for nutrients and space, particularly in the second year of growth. To improve transplanting rates and seedling quality, the second phase is typically managed in two different periods: one when the seedling is less than 20 cm tall, focusing on promoting vigorous growth, and another once it surpasses 20 cm, implementing measures to control stronger plants while stimulating weaker ones. II. Element Management Nursery element management encompasses water, light, temperature, fertilization, pest and weed control, and plant regulation. Each of these elements…

Tea tree cuttings are the primary means of propagating clonal tea seedlings. First, select a good mother garden of tea tree cultivars. During spring planting (February to March) or autumn planting (September to October), prune red-brown, semi-lignified, healthy, pest and disease-free branches with full axillary buds from the mother garden. Cut the branches into short cuttings 3 to 4 centimeters long, each with one leaf and a full axillary bud. Ensure that the cut is smooth and diagonal. (1) Method for Cutting Insertion Thoroughly moisten the seedbed before cutting insertion. Once the surface soil is no longer sticky, draw lines according to the length of the tea leaves. Generally, the row spacing for the cuttings should be 7 to 8 centimeters, and the plant spacing should be 2 to 3 centimeters, ensuring that the leaves do not overlap. Hold the lower part of the leaf of the cutting with your thumb, index, and middle fingers, then insert the cutting straight or slightly diagonally into the soil. The depth should be such that only the petiole is exposed. While inserting, lightly press the soil around the cutting to ensure it is firmly in contact with the soil, which aids root development.…

On July 1, our city experienced heavy rainfall, with 24-hour accumulated precipitation exceeding 100 millimeters at 23 monitoring stations, the highest being 172.9 millimeters at Changling station. The intense short-term rainfall led to landslides, collapsed embankments, mud accumulation, and waterlogging in some tea gardens, causing varying degrees of flood damage and related secondary disasters. To minimize losses from tea production due to disasters, Tongcheng Kangzhiyuan Family Farm promptly launched science popularization activities for disaster mitigation in tea gardens. Tea farmers can take the following remedial measures: 1. Drainage and Clearing of Silt and Waterlogging For tea gardens with standing water, drainage ditches should be promptly cleared and dredged, and deep trenches opened to drain the water as soon as possible, avoiding waterlogging that could harm the tea trees due to prolonged water accumulation. At the same time, mud, sand, stones, and other debris that have washed into the tea garden, as well as mud on the branches and leaves of tea plants, should be cleared away promptly. Efforts should be made to reduce soil moisture and environmental humidity as soon as possible to prevent root rot or decay caused by prolonged soaking of tea trees. 2. Restoration of Tea Gardens…

According to forecasts from our city's meteorological station, from 14:00 on July 10 to 08:00 on July 11, the average precipitation in our city was 52.6 millimeters, with a maximum of 179.2 millimeters. Four towns and streets experienced heavy rainstorms (100–250 millimeters), 24 towns and streets experienced storms (50–100 millimeters), and 13 towns and streets experienced heavy rain (25–50 millimeters). Other towns and streets experienced moderate rain (10–25 millimeters). To effectively mitigate the impact of disastrous weather on tea gardens and tea production and stabilize summer and autumn tea production, the following technical guidance is proposed. I. Strengthen Patrols and Preventive Measures in Tea Gardens The flood season has arrived, and strong winds and heavy rains may occur at any time. We should closely monitor weather forecasts. Before heavy rains, strengthen patrols of tea gardens and reinforce greenhouses and other production facilities. Check and dredge drainage ditches in advance; dig drainage trenches where necessary, especially in low-lying or high groundwater areas, where trenches should be at least one meter deep. Move tea, production materials, and equipment from low-lying areas as a precaution against heavy rains. II. Promptly Drain Flooded Tea Gardens After heavy rains, organize labor to drain water from…

Tea plants are perennial woody plants: they have a total developmental cycle that spans their entire life, as well as an annual developmental cycle that governs their growth and dormancy throughout the year. The total developmental cycle builds upon the annual cycle, which is constrained by and follows the rules of the overall development.Based on the reproductive characteristics of tea plants and practical applications in production, they can be divided into four biological age periods: seedling stage, juvenile stage, adult stage, and senescent stage. 1Seedling Stage of Tea Plants This typically begins from seed germination or successful cuttings until the tea plant emerges from the ground and reaches its first period of growth cessation, usually lasting for one year. The key management focus during this period is to ensure water supply, maintain humidity, and provide shade. 2Juvenile Stage of Tea Plants This stage runs from the first period of growth cessation (usually winter) until the tea plant is ready for commercial production. It generally lasts 3 to 4 years. The duration of this period is closely related to cultivation management and natural conditions. The juvenile stage is the most malleable period for tea plants. Cultivation practices must focus on shaping…

Although tea trees have a certain ability to withstand adverse weather conditions during their growth and development, they can be harmed if the conditions exceed a certain limit. This can range from reduced yield and quality of the leaves to the death of the tree. So what are the effects of low temperatures on tea trees? I. Common types of frost damage in tea trees The common types of frost damage in tea trees include snow frost, frost, and dry cold wind frost. In tea-producing areas south of the Yangtze River, snow frost and frost are predominant, while all three types of frost occur in areas north of the river. After being affected by frost, tea trees typically exhibit red withering or green withering. In areas south of the Yangtze River, red withering is more common, while both forms occur in areas to the north. II. The sequence of frost damage development in tea trees Tea trees have a certain ability to resist low temperatures, but different organs have varying degrees of cold tolerance. Among leaves, stems, and roots, cold tolerance decreases in that order. However, under field cultivation conditions, leaves protect the stems, and the stems and leaves together…

Good tea thrives with proper nutrition; fertilizers are the material foundation for increasing yield and improving quality in tea production. Fertilization plays a crucial role in the growth of tea plants and the yield and quality of tea leaves. While some nutrients are supplied by the soil itself, its nutrient content is limited and subject to environmental factors, leading to significant losses through leaching and volatilization, which greatly reduces nutrient availability. This is insufficient to meet the needs of tea plant growth, let alone high yields and quality standards. Additionally, as a leaf-harvesting crop, the annual harvest of large quantities of buds and leaves removes a certain amount of nutrients. Therefore, most nutrients must be replenished through fertilization. When soil nutrient imbalances occur or there is an extreme deficiency of one or more nutrients, it is necessary to use appropriate fertilizers to correct the nutritional deficiencies to ensure high-yield and high-quality tea production. Therefore, proper management of tea gardens during different seasons is crucial, and fertilization is a key technology in garden management that should receive significant attention. Especially during autumn, a critical period for tea garden management, the focus is on rapidly restoring tree vigor to lay the groundwork…

Tea gardens are characterized by a diverse range of weeds, complex weed communities, and strong stability. According to incomplete surveys and statistics, there are as many as 202 common weed species found in domestic tea gardens, belonging to 49 families and 163 genera. Weeds can impact the growth of tea plants, causing symptoms such as stunted growth, yellowing leaves, leaf drop, and delayed development. They may also carry diseases or pests that affect tea plants directly or act as intermediate hosts, indirectly impacting the growth and development of tea plants. "Grass to suppress grass" is an integral part of the green and efficient prevention and control technology system for Guizhou tea gardens, embodying the concept of "ecology at its root, agriculture at its core, and biological control first." Planting white clover in tea gardens can effectively suppress weeds and resist tea plant diseases and pests. Below are key technical points for reference. White clover in tea gardens and pollinating insects - bees Intercropping white clover in tea gardens Effective "grass to suppress grass" In recent years, research teams from Guizhou University, the Provincial Plant Protection and Inspection Station, the Provincial Academy of Agricultural Sciences, and the Provincial Soil and Fertilizer…

The main goal is to improve the soil condition, increase nutrient availability, and create favorable conditions for tea plant growth, with tasks including soil cultivation, weeding, fertilization, and moisture retention. I. Garden Cultivation Reasonable cultivation is an important measure to improve the soil condition in tea gardens, which can enhance the micro-ecological environment of the soil and provide good conditions for the growth and development of tea plants, improving their vigor. 1. Shallow Cultivation and Weeding The purpose of shallow cultivation in tea gardens is to remove weeds, loosen the surface soil, and improve the micro-ecological environment of the surface soil layer. The depth of shallow cultivation is generally around 5 cm, and it can be combined with top-dressing and soil mounding. It's also essential to clear weeds and brambles around the tea garden promptly. For young tea gardens that are not yet closed row, cultivation should be done whenever weeds appear, requiring six to seven weedings per year. Since the root system of young tea gardens does not penetrate deeply in the planting year, shallow cultivation before the high-temperature season should be done early to avoid drought immediately after cultivation. For mature tea gardens, cultivation is divided into spring,…
