Soil conditioner for pepper planting land and preparation method and use method thereof

Abstract

The invention relates to a soil conditioner for a pepper planting field and a preparation method and a use method of the soil conditioner. The soil conditioner is prepared from the following raw materials in parts by weight: 20 to 40 parts of bacillus subtilis decomposed mushroom residues, 10 to 20 parts of potassium humate, 5 to 10 parts of shell powder and 30 to 40 parts of diammonium hydrogen phosphate. According to the invention, the specific raw materials are proportioned, and the substances are matched with one another, so that the soil conditioner is rich in organic matters, potassium, nitrogen, phosphorus and various trace elements required in the production process of hot peppers, and the fertilizer efficiency is lasting and stable. The product meets the requirements of peppers for nutrients in different stages in the whole growth cycle, and the content of active organic matters in soil is increased; therefore, soil fertility and quality are improved, pepper continuous cropping obstacles are effectively improved, pepper yield increase and quality improvement are promoted, the pepper yield can be increased by 21% or above, and the nitrate content in peppers can be reduced by 13% or above. Moreover, the soil conditioner does not cause pollution to the environment and pepper products.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a soil conditioner for pepper planting fields, a preparation method and a use method thereof. Background technique [0002] Pepper is an important solanaceous vegetable, and its vitamin C content ranks first among all kinds of vegetables. At present, pepper planting area and economic value have surpassed cabbage to become the largest vegetable crop. With the expansion of pepper planting area and the increase of seed demand, the pepper seed production industry has developed rapidly. However, due to the highly intensive land in pepper planting areas Factors such as large-scale planting, high multiple cropping index, and single species have led to increasingly serious obstacles to continuous cropping of peppers, which eventually lead to a decline in the yield and quality of peppers. [0003] The causes of continuous cropping obstacles are complicated, among which the ...

AI Technical Summary

Problems solved by technology

After continuous cropping, due to soil salinization, acidification, and the continuous enrichment of pathogenic bacteria in the soil with the increase of continuous cropping years, continuous cropping obstacles often occur after 2-3 years of continuous cropping, plant growth and development are poor, and soil-borne diseases occur on a large scale. Such as pepper bacterial wilt, blight, root rot, etc. After the onset, the plants will wilt, the roots will rot, the growth points will not develop normally, and the fruits will lose water and rot into dark brown stiff fruits until the whole plant withers. In severe cases, the entire greenhouse may fail to harvest.

[0004] At present, the improvement technologies for continuous cropping soil habitat degradation of peppers and other crops of Solanaceae mainly include crop rotation, spraying and using chemical amendments, etc.; however, the method of spraying and using chemical amendments is likely to cause pollution to the environment and crops, and has little effect on alleviating continuous cropping obstacles. Stablize

Although crop rotation can reduce the occurrence of continuous cropping obstacles, it takes several to ten years, which is not suitable for the intensive cultivation mode of modern protected areas.

In addition, there are also chemical reagents such as methyl bromide, sulfacarb sodium, damonon, 1,3-dichloropropene, and chloropicrin to sterilize the soil to prevent the occurrence of soil-borne diseases and thereby reduce continuous cropping obstacles. Although these chemical reagents It can better control the occurrence of crop replanting diseases, but there are many serious problems such as phytotoxicity and environmental pollution.
