Fertilizer selection is mainly targeted supply of missing trace element fertilizers. Do not choose the so-called "Shiquan" liquid supplement, which is both expensive and untargeted, but the effect is not good. Therefore, it can be dominated by simple fertilizers. In view of the complexity of the fertilizer market, when individual farmers purchase micro-fertilizers, they must first choose the brand to buy genuine products, and second, they must jointly purchase the products.
If the concentration is too low, the effect will not be achieved, and if the concentration is too high, there will be fertilizer damage. The optimum concentration varies depending on the target crop, growth period, and element type.
Spraying frequency Spraying of fruit trees is usually effective only after spraying twice; in case of disaster or obvious symptoms, spraying is required 3-5 times.
Spraying leaves, stems, and young fruit can be sprayed, but special attention should be paid to the concentration of the flowers and buds. The number of stomata on the back of the leaf is more than that of the front, and absorption will be more.
Spray time should be avoided from wind, rain, and noon. It is better to use before 10 o'clock in the morning before 10 o'clock in the morning.
