1. In order to improve the use of bio-fertilizer, the following six points must be noted: First, understand the date of production, usage, usage and other relevant information of bio-fertilizer, and apply it within the validity period. Protect from light, ventilation and dryness during storage. The second is to understand the role of microorganisms, apply crops and application techniques, such as rhizobium for symbiotic nitrogen fixation in legumes, and different varieties of legumes have different rhizobial fertilizers. The third is to advocate the "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 is "near" from the crop root system; the seed and seedling fertilizer should be mixed "uniform". The fourth is to promote the application of organic fertilizer, which 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.
2. When using silicate bacteria, phosphorus bacteria, rhizosphere nitrogen-fixing bacteria, rhizobium and other biological fertilizers, the method of use is not good and the effect is poor. (Bilu)
