Embodiment Construction

[0024] The present invention is described in further detail below:

[0025] A milk vetch microbial fertilizer is made by mixing solid biological fertilizer and mycorrhizal fungus, and its weight ratio is 9 to 1. The solid biological fertilizer is fermented by placing liquid bacterial liquid in a carrier matrix, and the liquid bacterial liquid The strains are inoculated with Bradyrhizobium and Agrobacterium from Chinese milk vetch root nodule Huagui.

[0026] The mycorrhizal fungi are endomycorrhizal fungi.

[0027] The present invention also relates to a preparation method of milk vetch microbial fertilizer, comprising the following steps:

[0028] 1) To make a liquid medium, prepare soybean milk juice, yeast extract, beef extract, and peptone to prepare a liquid medium under autoclaving conditions at 121°C for later use, wherein the mass percentages of soybean milk juice, yeast extract, beef extract, and peptone are:

[0029] Soy milk juice 95-99.3 Yeast extract 0.2-0.8 Bee...

Abstract

The invention discloses a Chinese milk vetch microbial fertilizer. The Chinese milk vetch microbial fertilizer is prepared by mixing a solid biological fertilizer with mycorrhiza fungi in a weight ratio of 9 to 1, wherein the solid biological fertilizer is formed by fermenting a liquid bacterial liquid in a carrier substrate; and a bacterial strain of the liquid bacterial liquid is formed by mixing and inoculating bradyrhizobium and agrobacterium in mesorhizobium huakuii of the Chinese milk vetch. The invention further provides a preparation method of the Chinese milk vetch microbial fertilizer.

Description

technical field [0001] The invention relates to a microbial fertilizer, in particular to a milk vetch microbial fertilizer and a preparation method thereof. Background technique [0002] The development and application of microbial fertilizers play an irreplaceable role in ensuring food security and developing a low-carbon economy. Microbial fertilizers can replace 20% of chemical fertilizers. Under the premise of reducing chemical fertilizers by 20%, crops can still increase yields, improve the quality of agricultural products, and increase stress resistance. Milk vetch is an important organic fertilizer resource and the main winter green manure crop in paddy fields. It is of great significance for improving soil, fertilizing soil fertility, increasing grain production, and maintaining farmland nitrogen cycle in my country's farmland ecosystem. In addition to being used as a green manure crop, milk vetch can also be used as forage forage or prepared hay. It has good adapta...
