If tea is polluted, especially if it is exported, its output value and reputation will be seriously frustrated. In order to improve the quality and yield of tea, in addition to taking green manure in the tea plantations, covering moisture, applying farmyard manure after each harvest, and improving tea production techniques, it is also necessary to use foliar fertilizers, which is less fertilizer and quicker. A good way to achieve high returns can generally increase production by 20% to 30%. The fertilization technique is:
First, fertilization time. In the spring, summer and autumn rounds of tea germination, the new shoots sprouted at the beginning of one bud and one leaf. At the beginning of the exhibition, the windless sunny days, early evenings or cloudy days were sprayed and sprayed once every two or three times a week. Spray until the leaves are dripped.
Second, fertilizer ratio. Nitrogen, phosphorus, and potassium are the main components, supplemented by trace fertilizers, and the ratio is 4:1:1. Micronutrient fertilizers are formulated according to the principle of what is lacking in tea plants.
Third, fertilization concentration. Fertilizer concentration is related to fertilizer types and weather conditions. According to tests, urea is 0.5%, calcium superphosphate 1%, potassium sulfate 0.5%, zinc sulfate 50-100ppm, iron molybdate 20-50ppm. If the concentration is too large, it is easy to produce fertilizer, otherwise it will not be effective.
Fourth, multi-object combination. It can be combined with pest control, spray irrigation, and plant growth regulators to save labor and make it easy to implement mechanization. Fertilizer and pesticide chemical properties. Acidic fertilizers should be combined with acidic pesticides, and alkaline fertilizers should be formulated with alkaline pesticides so that no chemical reactions or precipitation will occur. This will prevent each other from neutralizing fertilizer effects and drug efficacy.
Fifth, using biological pesticides to control pests. Tea pest control using biological pesticides is safe and reliable, pollution-free and pollution-free, and the best choice for low cost and high effect, such as Bt emulsion, bacillus, Beauveria bassiana, agricultural antibiotics and plant antibiotics.
