At present, China's agricultural fertilizer utilization rate is only about 35%, and the rest is composed of three parts: loss, infiltration, and volatilization. Nearly two-thirds of the money used by farmers to buy fertilizer is wasted. At the same time, a large amount of fertilizer is lost. It also causes soil compaction and groundwater pollution. Therefore, it is imperative to apply chemical fertilizers scientifically and improve fertilizer utilization.
First, a comprehensive understanding of the basic information of biological fertilizers, such as production date, shelf life, usage, use methods. If it is not for current use, follow the instructions for storage, avoiding light, ventilation and drying.
Second, understand the main role of microorganisms in biological fertilizers, apply crops, etc. For example, rhizobial fertilizer is suitable for legume crops, as an inoculant for nodulation and nitrogen fixation; phosphorus bacterial fertilizer can convert poorly soluble phosphorus in soil into effective phosphorus and inorganic phosphorus.
Third, master the application time and application technology. It can be summarized by the words “early, near, and evenâ€, that is, the application time should be early, generally applied as base fertilizer, seed fertilizer and seed fertilizer; the distance from the root of the crop should be close when fertilizing; the seed and seed fertilizer should be mixed well.
4. Simultaneous application with organic fertilizer. The combination of the two fertilizers will increase the fertilizer effect.
5. Cover the soil immediately after fertilization to avoid direct sunlight, kill microorganisms, and reduce the utilization rate of biological fertilizer.
6. It should not be mixed with chemical fertilizers and fungicides, which will inhibit the growth of microorganisms in biological fertilizers and even kill microorganisms, thus affecting fertilizer efficiency.
The biological fertilizer is based on organic matter and is mixed with microbial and inorganic fertilizers. It can enhance soil activity and fertilizer efficiency, increase crop yield and promote the development of modern ecological agriculture under the premise of pollution-free, pollution-free and environmental pollution reduction. In order to improve the utilization rate of biological fertilizers, we mainly start from the above six aspects. (Ma Yimin)
