Clever foliar feeding for tea plants effectively improves quality

Growing Techniques 0 views
If famous tea is contaminated, especially export products, its output value and reputation will both suffer severe setbacks. To improve tea quality and yield, in addition to measures such as planting green manure in tea gardens, mulching to retain moisture, applying sufficient farmyard manure after each harvest, and improving tea-processing techniques, foliar fertilizer should also be used cleverly. This is a good method that uses little fertilizer, takes effect quickly and gives high returns, generally increasing yield by more than 20%-30%. The techniques are: Fertilization timing. When the new shoots of each round of spring, summer and autumn tea flush grow out to the initial unfolding of one bud and one leaf, choose a windless sunny morning, evening

If famous tea is contaminated, especially export products, its output value and reputation will both suffer severe setbacks. To improve tea quality and yield, in addition to measures such as planting green manure in tea gardens, mulching to retain moisture, applying sufficient farmyard manure after each harvest, and improving tea-processing techniques, foliar fertilizer should also be used cleverly. This is a good method that uses little fertilizer, takes effect quickly and gives high returns, generally increasing yield by more than 20%-30%. The techniques are: Fertilization timing. When the new shoots of each round of spring, summer and autumn tea flush grow out to the initial unfolding of one bud and one leaf, choose a windless sunny morning, evening or cloudy day for spraying, once a week for 2-3 consecutive sprays. Spray until droplets drip from the leaf surface. Fertilizer ratio. Base it mainly on nitrogen, phosphorus and potassium, supplemented by micronutrients, with a ratio of 4:1:1. The micronutrients 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 tests, 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; 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 matched with acidic pesticides, and alkaline fertilizers with alkaline pesticides, so as not to produce chemical reactions and precipitates, preventing them from canceling out each other's fertilizer and pesticide effects. Use biological pesticides to control pests and diseases. Using biological pesticides to control tea plant pests and diseases is the safest, most reliable, pollution-free and hazard-free option, and the best choice with low cost and high control efficacy, such as Bt emulsion, Bacillus thuringiensis preparations, Beauveria bassiana, agricultural antibiotics and plant antibiotics, etc.
