What are the precautions for the use of high-efficiency biological fertilizers? Before using the high-efficiency biological fertilizers, it is necessary to know the date of production, usage, usage and other relevant information of the biological fertilizers, and apply them during the validity period. Protect from light, ventilation and dryness during storage. Advocating with organic fertilizer can improve the application effect. The fifth is to avoid direct sunlight for a long time, and cover the soil in time after application. Sixth, it is not suitable to mix with chemical fertilizers and fungicides to avoid affecting fertilizer efficiency. In addition, it is necessary to pay attention to the use of silicate bacteria, phosphorus bacteria, rhizosphere nitrogen-fixing bacteria, rhizobium and other biological fertilizers, the use of improper methods, the effect is poor. The role of microorganisms in fertilizers, crops and application techniques, such as rhizobium for symbiotic nitrogen fixation in legumes, and different varieties of legumes have different rhizobial fertilizers. Advocate "early, near, uniform" application technology, that is, the application time should be "early", generally used as base fertilizer, seed fertilizer and seed fertilizer application; the application site should be "near" from the root of the crop; the seed and the seedling should be mixed.
