First, scientific selection. There is no additive effect on the application of foliar fertilizers and conditioners. It is not effective to put several foliar fertilizers or conditioners together; there are also a variety of foliar fertilizers and regulators. These practices are unscientific. Spraying more will even affect each other's effects. The scientific approach is to select 1 - 2 foliar fertilizers and regulators according to local conditions.
Second, can not replace fertilizer. High-quality foliar fertilizers and conditioners, although having a relatively obvious yield-increasing effect, have a certain promoting effect on improving crop quality and enhancing stress resistance, but they are not a substitute for chemical fertilizers. Foliar fertilizers and regulators can only exert a comprehensive effect on the basis of sufficient supply of fertilizer and water, and good control of pests and diseases. Foliar fertilizers and fertilizers should be combined, but less fertilizer should be applied and more fermented farmyard manure and bio-fertilizer should be applied.
Third, the correct application. Foliar fertilizer and conditioner, generally based on foliar spray, supplemented by dip and seed dressing. The application of foliar fertilizer is generally in the middle and late stages of crop growth, or when there is defatting. The application of the conditioning agent is generally used when the crop is overgrown or too slow, or for ripening. Spray on the foliage, young stems, fruits or ears of the crops evenly before 10 am or after 4 pm on sunny days. Spraying should be carried out according to the appropriate concentration of the variety used, and the dosage should not be increased arbitrarily, and the application concentration should be increased at will. So as not to cause a negative impact. Dissolve well when spraying, and use it with your equipment, and avoid strong sunlight or evaporation.
