Insect pest resistant solid state fermentation gel type fertilizer additive and preparation method thereof

Abstract

The invention discloses an insect pest resistant solid state fermentation gel type fertilizer additive and a preparation method thereof. The additive is prepared from the following raw materials in parts by weight: bacillus thuringiensis preparations, bacillus mucilaginosus microbial inoculums, lotus pool silt, 4mol / L NaOH solution, sweet potato peels, glucose, fishbone soup, ammonium bicarbonate, peat, humic acid powder, sweet potato stems, radix sophorae flavescentis, cortex meliae, garlic straws, pyrethrum cinerariifolium flowers, ginkgo leaves, vermiculite and a proper amount of water. Through the flocculation complexing effect of bacillus mucilaginosus, the effective period of the beneficial ingredients of plants in soil is greatly prolonged; great benefits are also achieved on the colloid formation of the soil.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an insect-resistant solid-state fermentation gel-type fertilizer additive and a preparation method thereof. Background technique [0002] Organic fertilizers in the traditional sense are used in the field after fermenting organic matter. Generally, the effect of organic fertilizers is to increase the content of organic matter in the soil, increase organic nutrients and reduce the use of inorganic fertilizers. The various organic fertilizers produced during the degradation process Organic acids can produce gel substances, which have a flocculation effect on the soil, improve the viscosity of the soil, and have the effect of water retention and fertilizer retention. The reduction in the use of inorganic fertilizers has far-reaching significance for the protection of the natural environment and sustainable development strategies. However, not all the actual applicat...
