Fertilization concentration. Fertilization concentration is related to fertilizer type and weather conditions. According to the test, urea is 0.5% and superphosphate is 1%. Potassium sulfate 0.5%, zinc sulfate 50-100 ppm, and iron molybdate 20-50 ppm. If the concentration is too large, it will cause fat damage, otherwise it will not be effective. Multi-object combination. It can be combined with pest control, sprinkler irrigation and plant growth regulators to save labor and facilitate mechanization. Chemical properties of fertilizers and pesticides. Acidic fertilizers should be matched with acidic pesticides, and alkaline fertilizers should be mixed with alkaline pesticides to prevent chemical reactions and precipitation, so as to prevent each other from offsetting the effects and effects. Use biological pesticides to control pests and diseases. Tea plant pests and diseases are safe, reliable, pollution-free and pollution-free, and have the best cost and low control efficiency, such as Bt emulsion, green worm, Beauveria bassiana, agricultural antibiotic and plant antibiotic.
Tea tree fertilization technology points
If the famous tea is contaminated, especially the exported products, its output value and reputation will be seriously frustrated. In order to improve the quality and yield of tea, in addition to adopting green tea in the tea garden, covering the moisturizing, applying the farmyard manure after each harvest, and improving the tea making process, it is also necessary to use the foliar fertilizer, which is less effective and less effective. Fast, high-yield good methods can generally increase production by 20%-30%. The technology is: fertilization time. In the spring, summer and autumn, the new shoots of the tea leaves grow a bud and a leaf at the beginning of the exhibition, choose no wind, sunny morning, evening or cloudy spray, spray 2-3 times a week. Spray on the leaf surface to drip. Fertilizer ratio. Nitrogen, phosphorus and potassium are the main sources, supplemented by micro-fertilizer, the ratio is 4:1:1, and the micro-fertilizer is based on the principle of what is missing from the tea tree.
