In the growth and development of tea plants, as many as 40 kinds of nutrients are required, of which the amount of nitrogen, phosphorus, and potassium is the most. Since tea leaves are used as materials, fertilizers suitable for the growth of tea trees are selected and managed during the early morning. , two deep, three feet, four well-being "four steps of fertilization, play a key role in improving the yield and quality of tea. It is easy to obtain high quality tea and ensure high yields.
Early in the morning: the use of base fertilizers in tea gardens is early. Generally, after entering the autumn, when the above-ground parts of the tea trees stop growing together with the winter tillage and weeding application, it is better to apply the base fertilizer early instead of early, so as to increase the utilization rate of the tea tree to the fertilizer and increase the nutrient value of the tea tree. Absorption and accumulation will help tea plants to resist cold and overwintering and the second year of spring tea shoots will have enough nutrients when they are formed and germinated, thus increasing tea yield and quality.
Second depth: Tea gardens should be fertilized deeply. The base fertilizer of the tea plantation should be deep ditched vertically below the edge of the canopy, and the depth should be 30 cm. Rings, rounds or opposites can be used for every year. Slopes of tea gardens or tea gardens with ladders. Fertilize above the tea line to prevent loss of fertilizer. After the fertilizer is applied, cover the soil immediately to prevent the fertilizer from volatilizing and affecting its fertilizer efficiency.
Three-legged: Tea garden base fertilizer to give enough, that is, the number of more. It is generally not less than 70% of the whole year. When applying basal fertiliser, proper amounts of phosphorus, potash and cake fat are applied. The dosage is: 1500 kg of organic fertilizer, 30 kg of superphosphate and 20 kg of potassium sulfate per acre.
Four well: It is the quality of the selected base fertilizer that is better. To make it possible to both improve the soil and slowly provide the nutrients needed for the tea tree. In short, the management of fertilization in tea gardens should be based on different tea gardens, using the most suitable fertilizer, and meet the requirements of “early, second, deep, three-legged, and four-goodâ€. It is easy to obtain high-quality and high-yield crops to ensure high yields.
