The problem of continuous reduction of land fertility is becoming a major problem facing Chinese farmers. Because of the continuous application of chemical fertilizers, the soil nutrient content decreased, the organic matter content decreased, and the soil compaction was severe. Bio-fertilizer can improve the utilization rate of chemical fertilizers, improve soil physical and chemical properties and enhance soil water retention, fertilizer retention and fertilizer supply.

Lao Zhang is a native peasant who has planted a lifetime. He said: Because of the continuous application of chemical fertilizers in the fields, there is a knot in the ground. The current land is not strong. In the past, one acre of fertilizer was used with two packs of urea. Now 10 The package can't play any big role. It seems to have entered a planting circle.

Biological bacterial fertilizer can change the land planting cycle. By applying microbial fertilizer to reduce the application amount of chemical fertilizer, it can obviously improve the soil, reduce the production cost, and improve the quality of the fruit.

Because the microbial fertilizer can activate the soil during the application process, it can decompose the nutrients fixed by the soil, thereby improving the absorption and utilization rate of the fertilizer; secondly, the microorganism can inhibit the occurrence and development of various soil-borne diseases during the growth and reproduction process. Root knot nematode disease also has a strong inhibitory effect.

Reasonable fertilization points

1. Select products with high documentation and high bacteria content.

2. Microbial fertilizers have low nutrient content and must be applied in combination with other fertilizers. When the microbial fertilizer is applied, since the microorganisms in the microbial fertilizer have the effects of nitrogen fixation, phosphorus dissolving, potassium dissolving, bacteriostasis, soil activation, and nutrient utilization, the application amount of the fertilizer can be appropriately reduced after the application of such fertilizer.

3. The microorganisms in the microbial fertilizer need to grow and reproduce in the soil with suitable water, so the soil moisture cannot be too dry and too wet.

4. Microbial fertilizers cannot be used simultaneously with fungicides.

5. Microbial fertilizers, whether they are base fertilizer or top dressing, should not be exposed to the soil surface.

6. Pay attention to the date of production, and the activity of microorganisms in microbial fertilizers that have been placed for too long is reduced.

7. The temperature in winter and spring is low, and the growth and reproduction of low-temperature microorganisms become slower and the activity decreases. The ground temperature should be raised and covered with straw, which is beneficial to increase the ground temperature and enhance the activity of microorganisms.
