Problems solved by technology

[0003] On the other hand, the incineration of rice, wheat, corn, rapeseed and other crop straws, and the disposal of livestock and poultry manure after large-scale breeding not only seriously pollute the environment, but also greatly waste the organic fertilizer and bio-organic fertilizer products. Raw materials; a large number of nutrient resources (C, N, P, K, S and trace elements) are lost outside the soil-plant system, which obviously weakens the ability of my country's agricultural sustainable development

Embodiment

[0026] Embodiment: ferment after mixing crop straw: livestock and poultry manure: inorganic nitrogen according to 30:68:2 (by dry weight), and keep it for 5-7 days when the compost temperature rises to 60-70°C (turn the compost once a day) , and then when the compost temperature reaches about 60°C, maintain it for 5-7 days (turning the compost once every 2-3 days), adding 0.5% inorganic nitrogen every time the compost is turned, until the compost temperature starts to cool down from 50-60°C, Keep it for another 3 to 5 days, stop immediately, and air dry for later use. The antagonistic bacteria liquid (spore formed) produced by fermentation is added to the fermented high-quality organic material and mixed to make a microbial organic fertilizer. The main properties of the product are shown in Table 1.

Abstract

The present invention relates to an antagonistic bacillus and microbial organic fertilizer produced by using said antagonistic bacillus for overcoming and eliminating continuous-cropping crop blight. Said invention utilizes a separation process to obtain the antagonistic bacillus which has obvious antagonistic action for blight fungus. The microbial organic fertilizer produced by mixing said antagonistic bacillus and organic farmyard manure is applied in the soil, then the antagonistic bacillus can be quickly reproduced, and the blight controlling rate can be up to above 80%.

Description

1. Technical field [0001] The invention discloses an antagonistic bacteria capable of preventing and eliminating the fusarium wilt of continuous cropping crops and its microbial organic fertilizer, which belongs to the intensive agricultural production technology and is specially used for overcoming and eliminating the fusarium wilt of continuous cropping crops. 2. Technical background [0002] The obstacles to continuous cropping of fruits, vegetables, cotton and other crops are the bottleneck of global intensive agricultural production. Thousands of hectares of protected agricultural soil are constantly being abandoned due to continuous cropping obstacles, which greatly wastes the financial resources, manpower and resources invested in facility agriculture. Material resources, even cucumbers, watermelons, tomatoes, soybeans, green peppers, cotton and other crops produced in large areas of open fields have serious continuous cropping obstacles due to successive plantings, wh...
