Soil continuous cropping diseases occur frequently. Farmers don't want to have a high yield when planting anything.

At present, due to continuous cropping for many years, most of the agricultural cultivated land in China has produced serious problems of continuous cropping, which has had a serious impact on all aspects of crop production, which is a problem that must be solved for the majority of farmers to obtain high yield and high yield.

What is the harm of repeating?

1. Soil-borne diseases are rampant, the phenomenon of dead seedlings and rotten plants of crops is serious, and root rot and Fusarium wilt occur repeatedly.

2. Soil nematode disease occurs frequently, resulting in a substantial reduction in crop yield, or even no harvest.

3. The crop has weak rhizome, poor disease resistance, less flowering and fruit setting, and lower yield.

Why does the succession come into being?

1. Long-term application of chemical fertilizers and pesticides, a large number of residual insoluble substances, resulting in soil acidification, consolidation, salinization and so on, crop breathing is not smooth, naturally affecting the absorption and utilization of nutrients and water.

2. Due to the continuous planting of the land, all kinds of bacteria and eggs gradually accumulated, coupled with the toxins produced by crop autotoxicity, harmful bacteria spread wantonly in the soil, beneficial bacteria could not be replenished in time, and the harm of diseases and insect pests became more and more serious.

3. Long-term cultivation of the same crop, single absorption of some nutrients, resulting in the lack of a large number of these nutrient elements in the soil.

How to solve the problem of continuous cropping?

The first step: turn the soil deeply before planting, remove the crop residue, use soil fumigant for disinfection and insecticidal.

The second step is to apply microbial agents to supplement the content of beneficial bacteria, curb the occurrence and development of pathogenic bacteria, improve soil structure, break consolidation, enhance soil water and fertilizer conservation capacity, and enhance crop growth and resistance.

The third step: reasonably increase the application of organic fertilizer, supplement the essential nutrients of crops, further enrich the soil, and solve the harm of continuous cropping in all aspects.
