The following three points should be taken into consideration when using organic fertilizer in vegetable gardens:
1, pay attention to the choice of high-quality organic fertilizer High-quality organic fertilizer is the basis for high-quality and high-yield vegetables, therefore, the production must use high-quality organic fertilizer, the choice of commodity organic fertilizer is the best choice of regular manufacturers. The application of inferior organic fertilizers to the soil is counterproductive.
2. Strictly control the amount of fertilization In general, 15 to 20 cubic meters of pure chicken manure is applied per acre of vegetable land. Solanaceous vegetables need a large amount of fertilizer, it is desirable to the upper limit; leaf vegetables need a little less fertilizer, it is desirable to the lower limit.
3, with a good effect of bio-fertilizer application Organic fertilizer regardless of the basic application and flushing, it is best to use biological fertilizer. Since organic fertilizers are applied together with biological fertilizers, biological bacteria in biological fertilizers can accelerate the decomposition of organic matter in organic fertilizers, making them more conducive to crop absorption, and at the same time can decompose and transform some harmful substances in organic fertilizers and avoid them. Vegetables cause harm.
Appropriate application of organic fertilizer in vegetable garden
The organic fertilizer is not applied as much as possible. Excessive application of organic fertilizer will also affect the physical and chemical properties of the soil. In severe cases, it will cause soil salt accumulation and affect the growth of the crop. Moreover, excessive application of organic fertilizer can also lead to the accumulation of nitrate in vegetables, which does not meet the requirements of standardized vegetable production.
