Mastering the spraying time According to the test, the spraying of wheat from the booting stage to the heading stage can significantly extend the functional period of the leaves and increase the grain yield, which is the best time for spraying fertilizer. In addition, due to the high temperature at noon on sunny days, large evaporation, and low fertilizer utilization rate, it is best to spray fertilizer on the semi-cloudy or sunny day before 10 am and after 4 pm, and rain 24 hours after spraying, it should be re-sprayed. Try to stagger the flowering period so as not to affect the normal pollination and fertilization of wheat and reduce the seed setting rate.
Determination of fertilizer type and amount of phosphorus and potassium according to seedling conditions can promote the synthesis and operation of wheat nutrients, accelerate grain filling and enhance plant lodging resistance; nitrogen can improve grain quality and prevent premature aging. Therefore, it is best to spray 0.3% potassium dihydrogen phosphate solution (300 g of potassium dihydrogen phosphate, 100 kg of water to spray 2 mu of ground) with normal or prone. For yellow thin and weak seedlings, add 1%~2% urea solution; for the leaves with thick color and dense growth, spray the wood ash leaching solution. Take 5-7 kg of fresh grass ash without rain, 100 kg of water, mix for 14 hours, and spray with clear liquid. Foliar fertilizers such as American Star or fulvic acid can also be sprayed.
The method of spraying fertilizer must be sprayed on the leaves, green stalks or wheat ears. At the same time, the front and back of the wheat leaves should be sprayed with fertilizer. To spray evenly, the finer the droplets, the better. For wheat fields with heavy de-fertilization and poor grievances, or dry hot winds during the spraying period, increase the number of spraying fertilizers as appropriate.
The first thing to note is that the type of mixing should not be too much. In actual operation, do not put several kinds of foliar fertilizer together, do not spray this today, and spray it tomorrow. The application of foliar fertilizer does not have an additive effect, and there are many types that even affect each other. In general, one or two applications should be selected depending on local conditions. The second is to choose the sunny day before 10 am or after 4 pm, spray evenly on the crop leaves, young stems and ears. Do not arbitrarily increase the dose and increase the concentration of application to avoid negative effects. The third is to dissolve fully when spraying, with the use of the use, to avoid strong light or rain and leaching. Fourth, in the "one spray three prevention", pay attention to the potassium dihydrogen phosphate should not be mixed with alkaline pesticides such as stone sulfur mixture, Bordeaux mixture, etc., in order to avoid the reaction to reduce fertilizer efficiency and efficacy.
