1. Choose high-quality and efficient foliar fertilizer and conditioner. When purchasing, it mainly depends on whether the inner and outer packagings are consistent, and whether the content is consistent with the internal content. The “three certificates†means whether the production license, product registration certificate and quality certificate are complete and valid, and whether they are within the validity period.
2. Scientific and reasonable ratio. Many farmers often mix several kinds of foliar fertilizers or conditioners, and think that the more complete the effect, the better. This is not necessarily scientific. Judging from the results of the current experimental demonstrations, the application of foliar fertilizers and conditioners has no additive effect, and even more spray effects may affect each other. Scientific approach: One or two applications should be selected according to the product description and the actual situation, avoiding unnecessary waste as much as possible.
3, can not replace fertilizer with foliar fertilizer or conditioner. High-quality foliar fertilizers and conditioners have a significant effect on yield increase, and they also have a certain promoting effect on the improvement of crop quality and the improvement of stress resistance. However, they must not replace fertilizers. They can only exert a comprehensive effect on the basis of adequate supporting measures such as adequate supply of fertilizer and water, and good control of pests and diseases. Therefore, foliar fertilizer and NPK fertilizer should be taken into account. However, it is necessary to apply less fertilizer, and it is better to use fermented farmyard manure and bio-fertilizer.
4. Master the application method and control the application concentration. Foliar fertilizer and conditioner products are generally sprayed on the foliar surface, while the application of dipping and seed dressing should be in accordance with the optimum concentration of the variety used, in the transition period of crop growth, before or after 10 am on sunny days. After 4 o'clock, it is sprayed evenly on crop leaves, young stems and ears. Do not arbitrarily increase the dose, and increase the concentration at will. This will not only cause waste, but even negative effects. When spraying, it is required to be fully dissolved, and it can be used as needed, and avoid strong sunlight evaporation or rain and leaching.
