Tea Garden

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…

Summer and autumn are critical periods for tea garden management. Strengthening summer and autumn tea garden production management is the foundation for ensuring high-quality and high-yield summer and autumn tea and the following spring tea. The Planting Industry Management Department of the Ministry of Agriculture and Rural Affairs, together with the National Agricultural Technology Extension Service Center, the Expert Advisory Group for Tea of the Ministry of Agriculture and Rural Affairs, and the National Tea Industry Technology System, have developed the following technical guidance on summer and autumn tea garden production management and disaster prevention and mitigation. Strengthening Tea Garden Production Management (1) Tea Plant Pruning - For year-round harvesting tea gardens, promptly perform the initial light pruning after spring tea harvesting, cutting off the top 5-10 cm of shoots from the canopy. During summer tea harvesting, it is advisable to allow some growth retention and use the leaf-retention method or tip-picking method to maintain an appropriate leaf layer thickness. Harvesting should be appropriately stopped earlier in autumn to avoid affecting the yield and quality of the following year's spring tea. To cultivate a good picking surface, the second light pruning should be completed before mid-July, with the pruning height…

Recently, in response to the persistent high temperatures and drought conditions across multiple regions of the province, the Provincial Tea Industry Technology System and the Science and Technology Service Team for the "515" Action Plan in the tea industry have been working under high temperatures and visiting grassroots levels to conduct research and guidance. Considering the actual situation of tea production in our province, the following technical measures are proposed to cope with extreme high-temperature weather, for reference by tea-producing areas. I. Emergency Technical Measures for Tea Garden Management 1. Timely and Reasonable Irrigation For tea gardens with irrigation facilities, various methods such as spray irrigation, drip irrigation, and surface irrigation can be employed to water the plants, preferably during the morning or evening. Spray irrigation is particularly effective, as it not only alleviates water shortages caused by drought but also reduces near-surface temperatures in the garden, mitigating the impact of high temperatures. When using surface irrigation, care should be taken to avoid excessive water flow that could result in surface runoff, wasting water resources and causing soil compaction in the tea garden. 2. Scientific and Effective Shading Using shade nets to provide shading for tea gardens can immediately and…

Guidelines for High-Temperature Drought Early Warning and Disaster Mitigation Measures in Tea Gardens Hunan Provincial Tea Industry Technology System Li Saijun & Li Wei July 25, 2024 Since early July, our province has been experiencing persistent high temperatures and droughts, with the drought rapidly worsening in most areas, severely impacting normal tea garden production. On July 25, the Hunan Meteorological Observatory issued the first red alert for extreme heat of the summer. In response to this extreme high-temperature and drought climate disaster, the Hunan Provincial Tea Industry Technology System has timely provided technical guidance, proposing specific measures for pre-disaster prevention and protection, as well as post-disaster recovery work in tea gardens. I. Pre-Disaster Prevention and Protection Measures (1) Interspace Covering ① Lay an appropriate amount of straw, fallen leaves, etc., in the gaps between tea plants to cover the soil surface at a thickness of 5-10 cm. This layer helps protect the soil, reducing water evaporation and aiding in the retention of nutrients in the soil. ② Intercropping green manure can effectively provide shade, reduce temperatures, and improve the microclimate within the tea garden, thus effectively preventing damage to tea plants from high temperatures and intense sunlight. (2) Scientific Shading…

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…

The “burnt pieces” in Pu'er raw tea are undesirable. However, this undesirability is not due to toxicity or harm to health but mainly affects the taste and appearance of the tea infusion. Theoretically, these “burnt pieces” can be avoided during the Pu'er tea production process; however, in practical application, they are almost impossible to avoid. The “burnt pieces” in Pu'er raw tea are essentially scorched tea juice that sticks to the iron wok and is not something dirty. During the process of fixing the fresh leaves, a large amount of water and tea juice overflow from the leaves, while the wok temperature is mostly above 200°C, which is very high. After several batches of fixing, a layer of tea juice forms on the surface of the iron wok, which is scorched black by the high heat and mixes with a small amount of the Pu'er tea material. We mentioned earlier that theoretically, “burnt pieces” can be avoided, and the most direct method would be to carefully clean the iron wok after each batch of fixing and before processing the next batch. If the scorched tea juice on the iron wok is completely washed off, it is theoretically possible to prevent…

Severe Infestation of Tea Looper How to Cope, Find Out Here It is currently late summer and early autumn, with cool weather in the morning and evening. This year has seen more rain than usual, resulting in vigorous growth of tea plants with lush green leaves, providing rich food for tea plant pests. According to investigations into the infestation of tea loopers in Longwu tea gardens, various age groups of larvae coexist, with severe overlapping generations. In some severely affected areas of tea gardens, the older leaves have been completely consumed, affecting the growth of tea plants, which requires close attention from tea garden managers. Due to differences in cultivation and management practices among individual households, the timing of infestations and the degree of damage vary across different tea gardens, making pest control challenging. It is essential to strengthen pest monitoring through field observations and the use of trapping devices, promptly understanding the dynamics of pest outbreaks and implementing appropriate measures: 1. Turn on insect-killing lamps, taking advantage of the fact that adult tea loopers are most active between 8:00 PM and 10:00 PM. Set the operating times of the lamps accordingly, ideally using a light-controlled mode where they automatically…

Main pests in autumn tea gardens and their control measures. The weather gradually cools down in September, with vigorous growth of tea plants and abundant food for pests, which is very conducive to the occurrence of pests such as mites and tea green leafhoppers. If not controlled in time, they can easily cause outbreaks that severely impact the yield and quality of next year's spring tea. The main pests occurring currently and their control measures are as follows: I. Tea Orange Spider Mite This pest is small in size, with adult and juvenile mites piercing and sucking tea plant sap. When mite numbers are low, the damage is not obvious and hard to detect. However, when mite numbers increase, the veins of affected leaves turn red, the leaves lose their green color and luster. Severe infestations result in a brown rust appearance on the underside of the leaves, withered and dried shoots and leaves, and a scorched appearance, and may even cause defoliation. Some tea gardens have experienced heavy infestations recently. Without effective control measures, mite populations will continue to rise. The following measures are recommended for control: 1. Strengthen garden management by removing weeds and fallen leaves. Timely picking…

According to the Rizhao City Meteorological Bureau's cold snap blue warning notice, affected by strong cold air, our city is expected to experience a cold snap from December 24th to 26th, with a temperature drop of 8-10°C. The lowest temperatures will occur on the morning of the 26th, with inland areas reaching around -10°C and coastal areas -8°C. On the 24th, daytime and nighttime northerly winds will strengthen to 5-6 on land, with gusts up to 8, gradually weakening on the 25th. Additionally, there will be sleet turning into light snow, with some areas experiencing moderate snow, from the daytime of the 24th through the night. Due to the significant temperature drop and low temperatures accompanied by light to moderate snow, there may be noticeable frost and snow damage, which could adversely affect tea plants overwintering in our city. To mitigate the impact of extreme weather on tea plants, the City Agricultural Technology Service Center has formulated technical guidance for tea gardens dealing with extreme weather. I. General Strategy for Winter Protection in Tea Gardens During Extreme Weather In the event of strong winds, heavy snow, and drastic temperature drops, timely winter protection measures should be taken for tea gardens.…

To prevent drought damage in tea gardens and reduce losses in tea production, supplementary measures to replenish water and suppress evaporation can be taken before the onset of drought. These include irrigation to supplement water, loosening the soil and weeding, inter-row grass covering, etc., to maintain and regulate soil moisture and improve the microclimate around the tea plants, thereby enhancing the tea trees' drought resistance. Irrigation Replenishment Tea garden irrigation methods include furrow irrigation, sprinkler irrigation, drip irrigation, among others, each with its own advantages and disadvantages. Furrow irrigation is suitable for flat tea gardens and can quickly increase soil moisture levels, promptly rescuing drought-stressed tea trees, but it consumes a large amount of water, has a small impact on air humidity, and can lead to waste of water resources through surface runoff and deep seepage, as well as damaging some of the topsoil structure. Drip irrigation reduces evaporation and saves water, but it requires a higher initial investment and cannot effectively improve the microclimate of the tea garden. Therefore, in recent decades, sprinkler irrigation has been the primary method used for drought prevention and mitigation in tea gardens. Sprinkler Irrigation can not only increase soil moisture but also lower…
