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, soil salt will accumulate and affect crop growth. Moreover, excessive application of organic fertilizer can also cause nitrate to accumulate in vegetables, which does not meet the requirements of standardized production of vegetables. The following three points should be noted in the vegetable garden when applying organic fertilizer:
First, pay attention to the selection of high-quality organic fertilizer, high-quality organic fertilizer is the basis for high-quality and high-yield vegetables. Therefore, high-quality organic fertilizer must be used in production. When using organic fertilizer, it is best to use regular large-scale production. After the inferior organic fertilizer is applied to the soil, the effect is counterproductive.
Second, strictly control the amount of fertilization Under normal circumstances, each mu of vegetable land to apply pure chicken manure 15 to 20 cubic meters. The solanaceous vegetables need a large amount of fertilizer, and the upper limit can be taken; the leafy vegetables need a slightly smaller amount of fertilizer, and the lower limit can be taken.
Third, with the effect of biological fertilizer application of organic fertilizer, regardless of base application and flushing, it is best to use biological fertilizer. Because organic fertilizer is combined with biological fertilizer, the biological bacteria in the biological fertilizer can accelerate the decomposition of organic matter in the organic fertilizer, making it more conducive to crop absorption, and at the same time, can decompose and convert some harmful substances in the organic fertilizer to avoid Vegetables cause damage.
