Methods for Skillfully Applying Foliar Fertilizer to Tea Plants to Improve Quality

Growing Techniques 0 views
If famous tea is contaminated, especially export products, its output value and reputation will suffer serious damage. To improve tea quality and yield, in addition to measures such as growing green manure in tea gardens, mulching to retain moisture, applying sufficient farmyard manure after each harvest, and improving tea-making techniques, foliar fertilizer should also be used skillfully. This is a good method that uses a small amount of fertilizer, takes effect quickly, and yields high returns, generally increasing yield by 20%-30% or more. The techniques are: Fertilization timing. When the new shoots of each round of tea in spring, summer, and autumn sprout and grow to the stage of one bud and one initial leaf, choose a windless sunny day at early morning, evening, or on a cloudy day for spraying, once a week for 2-3 consecutive sprays. Spray until water drips from the leaf surface. Fertilizer ratio. Mainly nitrogen, phosphorus, and potassium, supplemented by micronutrient fertilizers, with a ratio of 4:1:1. Micronutrient fertilizers are proportioned according to the principle of supplementing whatever the tea plant lacks. Fertilization concentration. The fertilization concentration is related to the fertilizer variety and weather conditions. According to experiments, urea is 0.5%, superphosphate 1%, potassium sulfate 0.5%, zinc sulfate 50-100 ppm, and ferric molybdate 20-50 ppm. If the concentration is too high, fertilizer damage is likely to occur; otherwise, it will not be effective. Combination with multiple substances. It can be combined with pest control, sprinkler irrigation, and plant growth regulators, saving labor and making mechanized operation easier to achieve. Chemical properties of fertilizers and pesticides. Acidic fertilizers should be combined with acidic pesticides, and alkaline fertilizers with alkaline pesticides, so as not to produce chemical reactions or precipitates, preventing mutual cancellation of fertilizer and pesticide efficacy. Use biological pesticides to control pests and diseases. Using biological pesticides to control tea plant pests and diseases is the best choice, as it is safe, reliable, pollution-free, and harmless, with low cost and high control efficacy, such as Bt emulsion, Bacillus thuringiensis, Beauveria bassiana, agricultural antibiotics, and plant antibiotics.
