Embodiment 1

[0022] The present embodiment adopts formula (parts by weight): 8 parts of bacterial liquid (soybean rhizobia, Bacillus megaterium, Lactobacillus acidophilus); Inorganic fertilizer (5 parts of potassium sulfate, 4 parts of urea, 5 parts of diammonium phosphate, monoammonium phosphate 2 parts); organic fertilizer (20 parts of chicken manure, 20 parts of duck manure, 20 parts of pig manure, 16 parts of straw powder). Prepare as follows:

[0023] (1) The strains of the 3 kinds of bacteria are respectively adopted conventional industrial fermentation technology, that is, the constant temperature shaking table of the triangular flask is expanded, and the two-stage fermentation process of the seed tank and the fermentation tank is used to input the 3 kinds of bacterial liquids that form spores after fermentation into the stirring tank respectively. , and add light calcium carbonate and diatomite accounting for 20% to 30% of the volume of the bacterial liquid into the tank as an adso...

Abstract

The invention relates to the field of soil microbiology, in particular to a microbial fertilizer for eliminating a continuous cropping obstacle and a preparation method thereof. The microbial fertilizer is prepared from the following raw materials in parts by weight: 4-10 parts of a bacterial liquid, 10-20 parts of an inorganic fertilizer and 70-85 parts of an organic fertilizer. The microbial fertilizer is prepared by scientifically mixing nitrogen-fixing bacteria, a phosphate-solubilizing microbial agent, an organic material decomposing microbial inoculum and an organic fertilizer. The microbial fertilizer plays a role in improving crop root system ecology under the actions of these fungi and optimizing a crop nutrient absorbing environment, so that continuous cropping crops grow normally, and the effect of increasing both production and income is achieved. The microbial fertilizer has the effects of improving soil, preventing soil-borne diseases, decomposing toxic substances in soil, promoting growth of plants and enhancing the stress tolerance of plants, and can be used for effectively eliminating the continuous cropping obstacles of crops.

Description

technical field [0001] The invention relates to the field of soil microbiology, in particular to a microbial fertilizer for solving continuous cropping obstacles and a preparation method thereof. Background technique [0002] Facility cultivation has become an important means of vegetable cultivation, which plays an important role in providing various fresh vegetables throughout the year. The main restrictive factor in the sustainable development of protected cultivation is the obstacle of continuous cropping, which is also a worldwide problem. It is only the obstacle of continuous watermelon cropping in greenhouses. Every year, Zhejiang melon farmers have to find nearly 300,000 mu of new watermelon fields all over the country. [0003] Continuous cropping obstacles mainly have three reasons: 1. Soil-borne diseases. Such as: cruciferous soft rot, melon wilt, solanaceous blight, blight, bacterial wilt, and nematodes. 2. Deterioration of soil physical and chemical propertie...
