The application of organic fertilizer plays an important role in improving crop yield and quality. However, with the advancement of science and technology and the continuous improvement of soil fertility level, it has been found in production that excessive application of organic fertilizer has produced many adverse consequences, which not only caused the accumulation of soil salt, but also the soil bulk density, organic matter and aggregates. Both microorganisms and microorganisms have adverse effects that adversely affect the normal growth of crops. In order to apply organic fertilizer efficiently and reasonably, experts remind us to pay attention to the following three points:
The first is to choose high quality organic fertilizer. At present, more and more commercial organic fertilizers are applied, but the quality of commercial organic fertilizers is generally low, and some even dope with municipal sludge, domestic garbage, etc., and simply do not meet the standard of organic matter content. Even some of the chicken dung that was bought, there is a lot of muddy soil. Therefore, it is necessary to build and select high-quality, non-polluting organic fertilizer in production, and fully decomposed. If you need to buy commercial organic fertilizer, you should use the regular large manufacturers.
The second is to strictly control the amount of fertilizer applied. Under normal circumstances, the control amount of vegetable land per acre per season is 1500-2000 kg of pure chicken manure or 50-100 kg of high-quality cake fertilizer, and fully-fertilized high-quality human and animal manure or soil-fertilizer 3500-4000 kg. Fruit and tuber vegetable crops require a large amount of fertilizer, which can be taken as an upper limit; while green leafy crops require a relatively small amount of fertilizer, the lower limit can be taken.
The third is to cooperate with the application of biological fertilizer. The biological bacteria in the biological fertilizer can accelerate the decomposition of the organic matter in the organic fertilizer, making it more conducive to the absorption of the crop, and at the same time decomposing and transforming some harmful substances in the organic fertilizer to prevent damage to the crop. Generally, when the organic fertilizer is applied, the biological fertilizer can be applied in an amount of 150 to 200 kilograms per mu; for the application, the biological fertilizer can be applied in an amount of 20 to 25 kilograms per acre.
