How to apply organic matter fertilizer?

How to apply organic matter fertilizer? Please guide the organic fertilizer if it can be made by itself, it is the most economical cost, but the actual implementation is not easy. Compared with the organic matter fertilizers sold in the market, the plant organic matter fertilizers with high nitrogen content such as rapeseed meal and peanut meal are more in line with the economic cost. Rapeseed meal is the main organic matter fertilizer used in rice organic cultivation in the central region. The ratio of nitrogen: phosphoric anhydride: potassium chloride is 5.3: 2.3: 1.3. Rapeseed meal is an unripe organic matter fertilizer, so special attention should be paid to its application amount and suitable application period. When rapeseed meal is used in rice cultivation, the recommended amount of rapeseed meal is 4000 kg per hectare. When base fertilizer is used, about 10 days before soil preparation, rapeseed meal can not only avoid the harm to rice growth caused by high temperature caused by rapeseed meal fermentation after transplanting seedlings, but also provide timely and appropriate amount of nutrients needed for rice growth. 1But 4 as topdressing, timely and appropriately supplement the absorption of fertilizer during the vegetative growth of rice, at this time, the root and aboveground parts of rice have grown very vigorously, not afraid of the high temperature harm caused by rapeseed meal fermentation. 1But 4 is used as panicle fertilizer, in general rice cultivation, panicle fertilizer is most suitable when young panicle formation is about 0.2 cm, but organic matter fertilizer takes time to mineralize in order to release nutrients, so it is suggested that the first stage should be applied about 8 ~ 10 days before young panicle formation, and the second stage should be applied about 6 ~ 8 days before young panicle formation. The application of organic matter fertilizer should be avoided after the young panicle formation stage, so as to avoid excessive nitrogen supply during the grain filling period, which will not only make the rice plant easy to lodge, but also increase the crude protein content in the grain, which is not conducive to the improvement of rice quality.
