Disease-resistant synergy-type conditioner of protected horticultural vegetable field soil and preparation method thereof

Abstract

The invention relates to a soil fertilizer technology and a crop disease and insect pest control technology, in particular to a disease-resistant synergy-type conditioner of protected horticultural vegetable field soil and a preparation method thereof, solving the problem that sustainable utilization of protected horticultural vegetable field is affected by the lowering soil quality. The soil conditioner comprises the following components in percentage by weight: 30-50% of medical stone powder, 20-30% of lime nitrogen, 20-30% of lignite, 5-10% of zeolite power and 5-10% of dicyandiamide. The preparation method of the soil conditioner comprises the following steps: medical stone powder screened by a 60-mesh screen, zeolite powder screened by a 60-mesh screen, the dicyandiamide and lignite are mixed and evenly stirred; then the mixture and granular lime nitrogen are mixed and evenly stirred; and after being completely mixed, the mixture is prepared into the soil conditioner. The preparation method of the invention is simple, has no pollution, can obviously improve fertilizer nitrogen and phosphorus utilization ratio of the protected horticultural vegetable field, effectively prevent and cure soil-borne diseases and has the effect on improving physical and chemical properties of soil at the same time.

Description

technical field [0001] The invention relates to soil fertilizer technology and crop disease and insect pest control technology, in particular to a disease prevention and synergistic facility vegetable field soil conditioner and a preparation method thereof. Background technique [0002] China's vegetable planting area is 19.7 million hectares, of which the protected vegetable cultivation area reaches 2.5 million hectares, accounting for more than 80% of the world's total protected vegetable area. Compared with the open field vegetable field, the facility vegetable field has the following characteristics: First, the utilization intensity is high, the utilization frequency is high, the multiple cropping index is high, and the planting density is large. Facility vegetable fields are recycled, and there is basically no fallow period. Second, the amount of fertilizer is large, whether it is chemical fertilizer or organic fertilizer, which far exceeds the crop demand. Excessive ap...
