Bacterial manure for peanut planting and preparation method of bacterial manure

Abstract

The invention provides a special bacterial manure for peanut planting, which comprises the following components in parts by weight: 5-25 parts of a compound microbial agent, 30-65 parts of dreg composite powder, 5-20 parts of starch and 10-25 parts of bentonite, wherein the compound microbial agent is composed of bacillus subtilis agent, a rhodopseudomonas palustris agent, a trichoderma harzianum agent and a paecilomyces lilacinus agent; the mass ratio of the bacillus subtilis agent to the rhodopseudomonas palustris agent to the trichoderma harzianum agent to the paecilomyces lilacinus agent is 5:2:1:2, and the total effective viable count of the compound microbial agent is10 billion cfu / g. The bacterial manure is mainly used as a base fertilizer, and can change the microenvironment around the roots of peanuts to prevent various plant diseases and insect pests while promoting nutrient absorption of the peanuts, so that the yield and quality of the peanuts are improved.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a microbial fertilizer for peanut planting and a preparation method thereof. Background technique [0002] Peanut is a traditional bulk export agricultural product in my country, and has strong competitiveness in the international market. According to statistics, in recent years, my country's annual peanut export volume has exceeded 600,000 tons, accounting for more than 40% of the world's peanut export volume, ranking first in the world. Peanut exporter. At the same time, peanut is the main oil crop. As early as the 1950s, peanut accounted for 34.2% of the total planting area of ​​oil crops and 59.5% of the total output of oil crops. With the improvement of people's living standards, the nutritional and health value of peanuts has been increasingly valued, the proportion of food processing has further increased, and the demand has continued to increase. However, with the...

AI Technical Summary

Problems solved by technology

In the main peanut producing areas, due to the large continuous cropping area and long continuous cropping period, peanut diseases and insect pests are very serious. Peanut root rot, bacterial wilt, leaf spot, net spot, grub and other diseases and insect pests have caused a production reduction of more than 40% in some areas. Due to the impact of bacterial wilt and grubs, some fields have lost their harvest, seriously affecting peanut production; at the same time, excessive use of chemical fertilizers and pesticides in the production process has caused heavy metal pollution and excessive pesticide residues in peanut products, seriously affecting the production of peanuts. quality of peanuts
