Organic fertilizer capable of disinfecting soil

Abstract

The invention discloses an organic fertilizer capable of disinfecting soil. The organic fertilizer contains abundant trichoderma viride, flowing actinomycetes, agrobacterium, bacillus subtilis, pseudomonas putida and other biological control bactericides as well as biological fumigant rapeseed meal and the like. After application of the organic fertilizer, pathogenic fungi, bacteria, nematode and other pests causing plant soil-borne diseases can be removed, the soil-borne disease problem can be solved quickly, safely and efficiently, and a healthy soil environment is provided for continuous cropping of vegetables. The organic fertilizer has the effects of bio-fertilizer, organic fertilizer and seaweed fertilizer, contains a large quantity of probiotics and seaweed functional active ingredients and can effectively regulate balance of microorganisms in the soil, decompose organic matter, mineral substances and other organic or inorganic ingredients in the soil, promote release of the organic matter in the soil, improve the physicochemical structure of the soil, increase soil aggregates, enhance permeability, improve the fertility of the soil and boost production capacity.

Description

technical field [0001] The invention relates to an organic fertilizer capable of disinfecting soil and belongs to the field of fertilizer processing. Background technique [0002] At present, the area of ​​protected gardening in my country is nearly 4 million hm 2 , of which the facility vegetable area is about 3.5 million hm 2 , with an annual output of 170 million tons, accounting for 25% of the total vegetable output in the country. The off-season, high-quality, and high-yield vegetable planting technology in the protected area not only greatly alleviates the problem of unbalanced seasonal vegetable supply in our country, but also becomes a resident. food basket. At the same time, it has also greatly improved the efficiency of land use and output, and has become an important channel for farmers to increase their income. [0003] However, there are still many problems in planting vegetables in protected areas: ① relatively single continuous planting for many years lead...

AI Technical Summary

Problems solved by technology

[0003] However, there are still many problems in planting vegetables in protected areas: ① relatively single continuous planting for many years leads to the accumulation of soil pathogenic bacteria year by year, breaks the ecological balance of microorganisms in the soil, and affects crop growth and yield, especially root-knot nematode disease, fusarium wilt, It usually takes 3 to 5 years for destructive diseases such as creeping blight, root rot, and bacterial wilt to occur from sporadic onset to widespread occurrence. Planting areas with more than 5 years are prone to large-scale outbreaks. ② The irrational use of fertilizers, especially the excessive use of nitrogen fertilizers, far exceeds the amount of nutrients required for crop growth, resulting in low utilization rates of nitrogen-based fertilizers. On the one hand, the nitrate content in vegetables increases, which reduces the quality of vegetables On the other hand, the leaching of nitrate nitrogen will also pollute the groundwater

At present, with the elimination of methyl bromide, there is a big gap between our country and the world's advanced countries in the development of soil disinfection products. The substitutes often have poor disinfection effects and serious soil secondary pollution. Therefore, it is our country to develop new, environmentally friendly and efficient soil disinfection products. The key to the development of facility agriculture
