How to beat the foliar fertilizer best? With the gradual increase of foliar fertilizer products, more and more farmers use foliar fertilizer. The farming network has sorted out five ways to increase the effect of foliar fertilizer, which are listed below for netizens' reference. Method 1. To prepare the best concentration of foliar fertilizer: spray foliar fertilizer to grasp the optimum concentration, which can achieve twice the result with half the effort. If the concentration is too high, it is easy to produce fertilizer or toxicosis; if the concentration is too low, it can not achieve the purpose of fertilization. The best concentrations of commonly used fertilizers are: urea 0.5% to 1%, diammonium phosphate 0.2% to 1%, calcium chloride 0.3% to 0.5%, zinc sulfate 0.05% to 0.2%. Method 2. Choose the best time to spray: generally, the best period for foliar fertilizer spraying is the seedling stage, the first flowering stage or the middle and late stage of fertilizer requirement of vegetables. Choose cloudy or sunny morning and evening spray, the effect is better, should avoid spraying in the scorching sun, should be timely spray after rain. Method 3, grasp the best spraying amount: 50 to 60 kg fertilizer per mu, the atomization degree of the sprayer should be improved as far as possible, the whole plant should be sprayed, and the new leaves and the back of the leaves should not be sprayed. Generally, vegetables should be sprayed 2 to 4 times during the whole growing period. Method 4. Select the best spraying position: the effect of foliar topdressing is related to the moving speed of spraying elements in the plant. The highly mobile elements are nitrogen, phosphorus, potassium, sodium and so on. All the mobile elements are phosphorus and sulfur, and some of the moving elements are iron, copper, manganese, molybdenum and so on. The effect of spraying the solution of element fertilizer which can not be moved or less mobile is better on the new leaves. Method 5. Reasonable spraying of mixed chemicals and fertilizers: mixed spraying of various foliar fertilizers, or mixed spraying of fertilizers and pesticides, can play a multi-effect role, but the properties of fertilizers and pesticides should be clarified first. If the nature is to the contrary, do not mix spray. When preparing the mixed solution, be sure to mix it evenly and mix it now. Generally, one kind of fertilizer is prepared into an aqueous solution, and then other fertilizers are directly added to the prepared fertilizer solution according to the dosage, and the solution is shaken well before spraying.
