In order to give full play to the role of bio-organic compound fertilizers, we must look at the sky, see the land, see the seedlings, and improve the application techniques. First, appropriate fertilizer. In the long-term drought conditions, bio-organic fertilizers should not be forcibly applied, and should be applied again until the rain is moderate. The criteria for suitable lyrical conditions are: the soil in the field is pressed into groups and the ground is scattered. Second, the amount of fertilizer. The organic standards of organic and organic fertilizers are different from those of other companies. When applying them, it is necessary to look at the nutrient content of the fertilizer formula, as well as the texture and fertility of the soil to determine the application amount. Generally, every 667 square meters ( 1 mu) The amount is about 50 kilograms, and the land with poor soil quality and low fertility is used appropriately, and vice versa. Third, mixed application. Bio-organic compound fertilizers are general-purpose and special-purpose, in order to reflect the fast-acting and long-term effects, they should be mixed with quick-acting fertilizers, especially with high-content compound fertilizers. The difference between different crops can be supplemented with potassium, boron, zinc and other large and trace element fertilizers, so that the effect is better.
