Embodiment 1

[0028] Composition A formula: 0.12 parts of naphthaleneacetic acid, 3 parts of 1,2-propanediol, 10 parts of grapefruit peel powder, and 0.12 parts of calcium chloride; just mix well.

[0029] Composition B formula: 3 parts of alkaline phosphatase, 3 parts of Streptocystis siberia, 6 parts of garlic powder, 10 parts of plant ash, 15 parts of soybean superfine powder, and 10 parts of glutinous rice flour;

[0030] Composition B preparation method is as follows:

[0031] (1) Mix alkaline phosphatase, Streptocystis siberica, soybean superfine powder and half of glutinous rice flour evenly to obtain a mixture;

[0032] (2) After mixing garlic powder, plant ash and the other half of glutinous rice flour evenly, add polyethylene glycol-water mixture (V polyethylene glycol: V water = 1:10) to the mixed powder, accounting for 3 times its weight ), stir evenly to obtain slurry;

[0033] (3) Slowly pour the mixture into the slurry, stir evenly, and then spray dry at low temperature; th...

Abstract

The invention belongs to the technical field of crop planting, and particularly relates to a seed-coating fungus for relieving peanut continuous cropping obstacles and a preparation method thereof. The coating bacteria agent includes composition A and composition B; composition A is naphthalene acetic acid, 1,2-propylene glycol, grapefruit peel powder, calcium chloride; composition B is alkaline phosphatase, Streptomyces siberia, Garlic powder, plant ash, soybean ultrafine powder, glutinous rice flour. The seed-coating fungus prepared by the invention can effectively improve the activity of soil enzymes, neutralize the acidic secretions in the soil, and improve soil fertility; the seed-coating fungus provided by the invention can promote the germination rate of peanuts and cooperate with the outer layer bacteria. Under the action of the pesticide, the peanut seedlings are strong; the bacterial agent provided by the invention can form a protective atmosphere around the peanut seeds, so that the diseases cannot multiply rapidly, the occurrence of diseases and insect pests is reduced, and the continuous cropping obstacle of peanuts is fundamentally eliminated.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a seed coating agent for relieving continuous cropping obstacles of peanuts and a preparation method thereof. Background technique [0002] Peanut is an important oil crop and economic crop in my country. The annual planting area of ​​peanut is 70 million mu, with a total annual output of about 17 million tons. Among the main oil-producing crops, the area is the third, and the total output and oil production per unit area rank first. . Peanut is a kind of crop that is more sensitive to continuous cropping, and the yield of pods decreases by 19.8%-33.4% after 2-3 years of continuous cropping, and the quality decreases. After continuous cropping of peanuts, soil-borne diseases such as bacterial wilt, sclerotinia, and root-knot nematode will increase year by year; aphids, red spiders and other above-ground insect pests will increase year by year due to the increasi...
