Problems solved by technology

Long-term continuous cropping of broad beans is prone to continuous cropping obstacles, slow growth of broad beans, short plants, reduced root nodules, prone to disease, low yield, and reduced quality. Large-scale application of chemical fertilizers causes environmental pollution and excessive greenhouse gas production
[0003] At present, stubble changing and intercropping are commonly used in production to solve the obstacles of continuous cropping of broad beans, but the economic benefits obtained by farmers have declined
At the same time, the large-scale application of chemical pesticides has caused serious environmental pollution and ecological balance dam

Abstract

The invention provides a horsebean biological compound fertilizer prepared from ardealite, a preparation method thereof and use thereof. The biological compound fertilizer is prepared by the following steps: uniformly mixing fermentation liquor of horsebean rhizobia, glomus fasciculatum, phosphate solubilizing bacteria and the like; adding ardealite, zinc sulfate, sodium molybdate, manganese sulfate, borax, magnesium sulfate, peat, cut tobacco cutoffs and the like; adjusting water content to 20 to 40 percent; uniformly mixing to make each gram of the mixture contain 3 to 8*10<8> horsebean rhizobia, 2 to 6*10<5> glomus fasciculatum, 53 to 9*10<8> phosphate solubilizing bacteria, 15 to 35 percent of ardealite, 35 to 48 percent of peat and 0.5 to 5 percent of cut tobacco cutoffs and the like; and obtaining the product. To be used, the product is added with a proper amount of water and prepared into mud paste; and the paste is mixed with horsebean seeds uniformly, and the mixture is driedin the shade. The product is suitable to be used in horsebean planting areas, particularly horsebean continuous cropping areas, for relieving the horsebean continuous cropping obstacles, promoting horsebean growth, eliminating cropping obstacles, inhibiting horsebean disease and improving horsebean yield and quality.

Description

1. Technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special biological compound fertilizer for broad beans and its preparation method and application. 2. Background technology [0002] Broad bean is a vegetable with medicinal and health functions, which can be eaten raw or cooked. Long-term continuous cropping of broad beans is prone to continuous cropping obstacles, slow growth of broad beans, short plants, reduced root nodules, prone to disease, low yield, and reduced quality. Large-scale application of chemical fertilizers causes environmental pollution and excessive greenhouse gas production. [0003] At present, stubble changing and intercropping are commonly used in production to solve the obstacles of broad bean continuous cropping, but the economic benefits obtained by farmers have declined. At the same time, the extensive use of chemical pesticides has caused serious environmental pollution and ecolo...
