Abstract

The invention belongs to the technical field of soil improvers, and in particular discloses a high-carbon-based soil additive prepared from fermented soybean straw. The high-carbon-based soil additive is prepared from soybean straw as a degradation raw material added with composite bacteria, wherein the composite bacteria comprise the following bacteria: phanerochaete chrysosporium, trichoderma koningii, paracoccus denitrificans, rhodococcus and succinic acid bacillus filiformis in a ratio of (1-3):(2-8):(3-8):(1-3):(2-8). According to the nutrient components of soybean straw, five composite bacteria are adopted to ferment and degrade soybean straw, due to the complementarity and the synergistic effect of the bacteria, not only is the soybean straw sufficiently degraded within a short time, but also the physicochemical property of soil can be improved by using the prepared soil additive, plant growth and development can be improved, resistance of plants can be induced to improve, properties such as cold resistance, drought resistance, disease resistance and inversion resistance can be improved, the yield can be increased, and the product quality can be improved.

Description

technical field [0001] The invention relates to the technical field of soil improvers, in particular to a soil high-carbon-based additive prepared from fermented soybean stalks. Background technique [0002] Straw is a by-product of crops, which is the crop residue left after the seeds are harvested, including cereals, beans, potatoes, oilseeds, hemp, and various crops such as cotton, sugar cane, tobacco, melons and fruits. As the renewable resource with the largest storage capacity in nature, straw cellulose has a global annual output of up to 100 billion tons. my country is a large agricultural country with rich crop straw resources. At present, there are nearly 20 kinds of important crop straws, with an annual output of up to 7 to 1 billion tons. With the adjustment of rural industrial structure, the proportion of economic crop straw has also increased. In addition to a large amount of carbon, crop straw also contains nitrogen, phosphorus, potassium, calcium, magnesium, ...
