According to the seedlings, determining the type and amount of fertilizer phosphorus and potassium can promote the synthesis and operation of nutrient substances in wheat, accelerate grain filling, and enhance plant resistance to lodging; nitrogen can improve grain quality and prevent premature aging. Therefore, the growth of normal or prosperous wheat, it is best to spray 0.3% potassium dihydrogen phosphate solution (300 grams of potassium dihydrogen phosphate, 100 kg of water sprayed 2 acres of land). For yellow thin and weak seedlings, spray 1%~2% of urea solution; for leaf thick, dense growth of Wang Miao, can spray spray ash liquid. Take fresh grass ash 5-7 kg without rain, against 100 kg of clean water, stir for 14 hours, and take clear liquid. It is also possible to spray foliar fertilizers such as American Star or fulvic acid.
Spray fertilizer methods must be appropriate fertilizer spray must be sprayed on the leaves, green stems or wheat ears. At the same time, the front and back of the wheat leaf should be sprayed with fertilizer solution. To spray evenly, the finer the mist, the better. In the case of a barley field with poor weight and poor sensation, or a dry hot wind during the spraying period, it is necessary to increase the number of spraying fertilizers as appropriate.
One note is that the type of mixture should not be too much. In actual practice, do not use several kinds of foliar fertilizers together, and do not spray them today. Spray them again tomorrow. The application of foliar fertilizers does not have an additive effect, and the types or even effects of each other will play a role. In general, one to two applications should be selected depending on local conditions. The second option is to spray evenly on the affected parts of the crop leaves, young stems and ears after 10 o'clock in the morning or after 4 o'clock in the afternoon. Do not arbitrarily increase the dose and increase the application concentration to avoid negative effects. The third is to fully dissolve the spray, with the use of the distribution, to avoid strong light or rain leaching. Fourth, in the "one spray and three defenses", it should be noted that potassium dihydrogen phosphate should not be mixed with alkaline pesticides such as lime sulfur and Bordeaux mixture in order to avoid reactions that reduce fertilizer efficiency and efficacy.
Wheat spray foliar fertilizer need to pay attention to it?
Grasp the spraying time According to the experiment, spraying fertilizer from wheat booting to full heading can significantly extend the functional period of leaves and increase 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, spraying fertilizers should be carried out before 10 o'clock in the morning or at 4 o'clock in the morning on sunny days, and rain should be sprayed after 24 hours after spraying. Try to stagger the flowering period so as not to affect the normal pollination and fertilization of wheat and reduce the seed setting rate.
