Organic fertilizers are most economical if they can be made by themselves. However, actual implementation is not easy. Comparing organic fertilizers with market prices, plant-based organic fertilizers with high nitrogen content, such as rapeseed meal and peanut meal, are more economical.
Rapeseed meal is the main organic fertilizer used for organic cultivation of rice in the central region, and the nitrogen:phosphoric anhydride:potassium chloride ratio is 5.3:2.3:1.3. Rapeseed meal is an organic fertilizer that has not been decomposed, so special attention should be paid to its application amount and appropriate application period. The application of rapeseed meal in paddy rice cultivation is recommended at 4,000 kg per hectare. When 1/2 is used as the base fertilizer, it is applied about 10 days before the site preparation. This will not only avoid the high temperature produced by the rapeseed meal fermentation but also increase rice growth after transplanting. Hazard, and can provide timely and appropriate amount of nutrients required for rice growth; 1/4 as top-dressing, timely and appropriate supplementation of rice nutrient absorption during vegetative growth, rice roots and shoots have grown very strong at this time, not afraid of food High-temperature hazards produced by the seed meal fermentation; 1/4 used as panicle fertilizer, general rice cultivation, panicle fertilizer is most appropriate when the young panicle formation is about 0.2 cm, but the organic fertilizer can only be released due to the time required for mineralization. Nutrients, so it is recommended that the first phase of about 8 to 10 days before juvenile ear formation, the second phase of about 6-8 days before juvenile ear formation is the most appropriate application.
Organic fertilizers should be avoided after the spikelet formation period, so as to avoid excessive nitrogen supply during grain filling. This not only makes the rice plants easier to lodging, but also increases the crude protein content in the grain, which is not good for rice quality. The promotion.
