Problems solved by technology

The bio-organic fertilizer can improve the soil structure and water holding capacity to a certain extent, and suppress the continuous cropping obstacles of flue-cured tobacco; however, as a bio-organic fertilizer, it still mainly provides fertilizer effect for plant growth, and has limited improvement effect on soil, and cannot better inhibit crops. soil borne diseases

Abstract

The invention relates to a crop continuous-cropping soil improver and a preparation method of same and belongs to the technical field of production of agricultural fertilizers. The soil improver is mainly produced from, by weight, 4-6 parts of a microorganism fermentation inoculant, 30-50 parts of dried cow dung, 4-6 parts of straws, 30-48 parts of weathered coal, 8-12 parts of a microorganism beneficial composite inoculant, and 1.5-2.5 parts of nano carbon. By means of wastes in breeding industry and agriculture as raw materials, a decomposed organic fertilizer is prepared through fermentation by the microorganism inoculant, and then the weathered coal and the soil beneficial inoculant are added to perform secondary fermentation, and finally, the nano carbon is added and mixed with the fermentation product to produce the soil improver. The soil improver, in a bio-improvement manner, has excellent soil improvement effect on the basis of continuous-cropping obstacle formed by continuous cropping, and also can effectively inhibit soil-borne diseases and also supplies nutrients to soil. The soil improver is harmless to environment. By means of the wastes in breeding industry and agriculture as raw materials, the soil improver is low in cost, turns wastes into resources and is suitable for being promoted and applied.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizer production, and in particular relates to a soil improver for continuous cropping and a preparation method for the soil improver for continuous cropping. Background technique [0002] Continuous cropping refers to planting the same crop of the same kind or the same family in the same field for many years. In recent years, crop continuous cropping has become a common phenomenon, resulting in more and more serious soil-borne diseases of continuous cropping soil, that is, continuous cropping obstacles. Mainly due to the imbalance of microbial structure in the soil, the pH of the soil environment decreases, which affects the activity of soil enzymes. [0003] The continuous cropping of crops will lead to different degrees of yield decline, poor quality, breeding of diseases and insect pests, and poor breeding status. Some substances are released through leaching of aboveground parts, ...
