First, choose a good quality foliar fertilizer. When choosing to purchase foliar fertilizer, pay attention to the trademark, enterprise standard number, product quality certificate, agricultural use registration certificate, factory name, factory address, production date, packaging, whether the packaging is intact, liquid fertilizer should pay attention to solubility. How, with or without precipitation.
Second, spray foliar fertilizer should be targeted. It is generally believed that in the case of insufficient base fertilizer, foliar fertilizer mainly based on nitrogen and phosphorus fertilizer can be selected; when sufficient application of base fertilizer is applied, foliar fertilizer mainly based on trace elements should be selected, and growth can also be selected according to different needs of crops. Adjust the foliar fertilizer of the substance. For example, when cotton is sprayed with boron fertilizer in the bud stage, it can prevent falling buds and increase the length of fiber and the content of clothing. The application of zinc in rice and corn can prevent rice seedlings and corn white seedling disease; peanuts and soybeans planted in acid soil in the south. Application of molybdenum-containing fertilizer can increase oil content and protein content; application of brassinolide can make vegetables mature in advance, reduce cellulose content, improve taste and increase sugar content.
Third, the foliar fertilizer spray concentration should be appropriate. Spraying foliar fertilizer must strictly control the spray concentration, especially for foliar fertilizers containing growth regulating substances. For example, tridecyl alcohol at a concentration of 0.5 to 1 ml/L can promote seed germination, but a concentration of more than 1 ml/L will inhibit seed germination. Therefore, it is necessary to carry out the spraying in strict accordance with the concentration required by the instructions for use of various foliar fertilizers.
Fourth, grasp the best spraying time and location. In order to facilitate the absorption of nutrients by crops, the spraying time is best selected in the early morning or evening when the wind is not strong. In case of heavy rain within 24 hours after spraying foliar fertilizer, spray again. If sprayed in a small area, it can be sprayed on the back of the leaf because the back of the leaf absorbs nutrients faster than the leaf surface.
Application technique of crop foliar fertilizer
The main role of foliar fertilization is to compensate for soil fertilization, prevent premature senescence, and promote crop nutrient balance. Proper use of foliar fertilizer not only enhances crop stress resistance, but also improves crop quality and increases crop yield. To effectively improve the use of foliar fertilizer, the following points should be noted when using:
