Scientific fertilization of tea plants in winter is an important management measure in tea production. Winter fertilization not only helps to improve the absorption and utilization of soil nutrients by tea plants, but also enhances the stress resistance of tea plants and promotes the healthy growth of tea plants. In this paper, we will introduce the scientific fertilization method of tea plants in winter, in order to provide a useful reference for tea production.
1. Determine the fertilization time and amount.
The best time to fertilize tea trees in winter is after the tea plants stop growing, generally from mid-to-late November to early December. At this time, fertilization is conducive to the absorption of nutrients by the roots of tea plants, and promotes the growth of tea trees in wintering and the next year. When determining the amount of fertilizer, it should be considered comprehensively according to factors such as tea plant growth, soil fertility and tea yield. Generally speaking, 1000-1500 kg of organic fertilizer can be applied per mu of tea garden, with an appropriate amount of compound fertilizer and trace element fertilizer.
Second, choose the right type of fertilizer.
In winter, the fertilization of tea trees should be mainly organic fertilizer, with an appropriate amount of compound fertilizer and trace element fertilizer. Organic fertilizer has the advantages of comprehensive nutrients, long fertilizer efficiency, and improved soil structure, which is conducive to improving the water and fertilizer retention capacity of soil. Compound fertilizer and trace element fertilizer can provide the nutrients needed for the growth of tea plants, promote the growth of tea plants and improve the quality of tea leaves.
3. Reasonable fertilization methods.
When fertilizing, organic fertilizer and compound fertilizer should be evenly spread between the rows of tea trees, and then deeply turned. The depth of the deep plough should reach about 20 cm to promote the absorption of nutrients by the roots. For sloping tea gardens, fertilizer can be sprinkled directly around the roots of the tea trees and properly cultivated to prevent fertilizer loss. In the process of fertilization, attention should be paid to avoid direct contact between the fertilizer and the root system, so as not to cause root burning.
4. Strengthen water management.
After fertilizing the tea trees in winter, the tea garden should be watered in time to promote the dissolution and absorption of nutrients. When watering, avoid watering too much or too little, so as not to cause water accumulation or drought. At the same time, it is necessary to pay attention to the coordination of water temperature and soil temperature to avoid damage to the root system of tea trees caused by excessive temperature difference.
Fifth, pay attention to safe fertilization.
In the process of fertilization, attention should be paid to safety issues. First of all, it is necessary to choose fertilizers that meet national standards and avoid the use of fake and shoddy fertilizersSecondly, in the process of fertilization, attention should be paid to personal safety and environmental protection;Finally, after fertilization, the residual fertilizer should be cleaned up in time to avoid environmental pollution.
In short, scientific fertilization of tea trees in winter is an important management measure in tea production. When fertilizing, we should choose the appropriate fertilizer type and fertilization method, reasonably arrange the amount of fertilizer and watering time, and pay attention to the problem of safe fertilization. Through scientific fertilization, the yield and quality of tea can be improved, and the sustainable development of the tea industry can be promoted. At the same time, it is also conducive to improving the economic benefits and living standards of tea farmers, and making positive contributions to the development of rural economy.
