Organic fertilizer is not only an ideal base fertilizer, but also a top dressing. It is the main fertilizer type that provides nutrients during crop growth. Organic fertilizer should pay attention to the following matters when doing topdressing:
1. Chasing in advance. Organic fertilizers contain fast-acting nutrients, but the amount is limited. The release of a large number of slow-acting nutrients requires a certain process. Organic fertilizers should be applied a few days earlier.
2. Pursue high quality organic fertilizer. During the rapid growth of crops, a large amount of nutrients such as nitrogen and potassium are needed. Generally, the nitrogen and potassium nutrients in organic fertilizers are not high. To ensure the rapid growth of nutrients, high-quality organic fertilizers with high nitrogen and potassium nutrients should be used.
3. Formulate a reasonable proportion of base fertilizer distribution. When the ground temperature is low, the microbial activity is weak, and the release of organic fertilizer nutrients is slow. Most of the application amount can be applied as the base fertilizer; when the ground temperature is high, the microbial decomposition ability is strong. If the amount of base fertilizer is too much, the fertilizer is excessively decomposed by the microorganisms before planting. Immediately after planting, the fertilizer effect is exerted, sometimes causing the crop to grow. Therefore, in the cultivation of crops under high temperature conditions, it is best to reduce the amount of base fertilizer application and increase the amount of topdressing.
4, nursery should be appropriate. Crop seedlings need small amounts of nutrients, but insufficient nutrients can not form strong seedlings, which is not conducive to transplanting, and is not conducive to future crop growth. Fully decomposed organic fertilizer, nutrient release and nutrient comprehensive, is an ideal fertilizer for seedlings. Generally, a certain amount of grass carbon, vermiculite or perlite is added by fermenting the organic fertilizer, and the soil is uniformly mixed to make the seedling substrate. The amount of the organic fertilizer cannot exceed 10% of the total weight of the nutrient soil.
