Nitrogen should generally be in fruit growth stage, late stage, with an appropriate phosphorus and potassium. Spraying appropriate concentration can effectively promote efficient foliar shoot growth, improve fruit yield beneficial flower buds. Early use of urea concentration of 0.2% to 0.3%, the latter using a concentration of 0.3% to 0.5%; composting human waste pre-concentration of 0.5%, the latter using a concentration of 10%. Less fertilizer foliar spraying should have early, middle and late more than principle. In the best ammonium concentration of 0.5% to 1%; potassium dihydrogen phosphate at a concentration of 0.2% to 0.5%; superphosphate leaching solution at a concentration of 1% to 3%. Not blindly mix: In order to improve efficiency, foliar spraying should spray mixture. The mixture can be "Combo" (foliar + insecticides, plant growth regulator foliar +) foliar series, or "triple play" (+ foliar insecticide + fungicide) , or "Four" (foliar fungicide + + + insecticide plant growth regulator). But pay attention to each of these fertilizers and pesticides foliar price performance, see if you can mix, otherwise it will reduce fertilizer and efficacy, or even cause fertilizer damage and injury. Pesticides and fertilizers have acidic, basic and neutral points, usually only can be mixed between homosexual. Such as precipitation, stratification, turning bubble or floating oil and other phenomena; speed test whether the pesticide can be mixed with fertilizer, can put a little bit of each whichever water, such as the mixed solution evenly without any reaction, you can mix , you can not mix.
