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…

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…

Weed control is a critical aspect of managing young tea gardens in Guizhou. Techniques such as manual weeding, tillage weeding, and mulching have proven effective, but they require significant labor and material inputs. Manual weeding alone can cost 700 to 800 RMB per mu, increasing the overall management costs of the tea garden. Intercropping soybeans in young tea gardens can effectively suppress weed growth, improve the ecological environment, and enhance soil fertility. Additionally, this practice generates supplementary income of around 1,000 RMB per mu. Soybeans are an important oilseed crop, and China's current production falls short of domestic demand. Intercropping soybeans in young tea gardens aligns with national policies aimed at increasing soybean production capacity and ensuring food security. To leverage the weed control and soil fertility benefits of intercropping soybeans, the Guizhou Academy of Agricultural Sciences Tea Research Institute has developed this plan. Soybean intercropping in tea gardens in Datun Village, Shiqian County General Requirements 1. Adhere to Tea Garden Safety Principles All pesticides and fertilizers used in tea gardens must comply with Guizhou's safety standards. No pesticides or fertilizers prohibited in tea gardens should be applied, even if they are suitable for soybeans. 2. Balance Tea Management and…

Let's start with a chart of the Longjing family relationships. The head of the family is Hang Jiahe, who has a daughter named Hang Pan with his former wife Fang Xiling. In the previous article, we mentioned the love at first sight between Hang Pan and Nationalist pilot Cao Jiayuan. Hang Pan is in charge of overseeing hundreds of acres of tea garden, including the famous Lion Peak Hu Gong Temple area. By "overseeing," it mainly means managing the garden rather than preventing others from stealing tea leaves. During the month or so when Longjing tea is picked and processed, there are many people bustling about on the mountain, making it difficult to steal tea. If it's not the picking and processing season, stealing tea would be pointless because the resulting tea would taste terrible and couldn't even be sold as vegetables. Hang Pan's oversight is essentially garden management. The People's Liberation Army took over ten days to capture Hangzhou, officially announcing its liberation on May 3, 1949. The first third of "Looking South of the River" describes the winter and spring before the liberation of Hangzhou. In her diary, Hang Pan wrote: "The fighting has started again, and everywhere…

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…
