Problems solved by technology

Long-term continuous cropping of peanuts is prone to continuous cropping obstacles. Peanuts grow slowly, are prone to disease, low yield, and quality decline. Large-scale use 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 peanut continuous cropping, 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 damage, and the quality of peanuts has declined, posing potential hazards to human health.
[0004] Seed coating agents have been developed for many years, but most of the seed coating agents contain highly toxic pesticides, which seriously pollute the environment and are harmful to the production process and application process of the coating agent, which restricts production and application

Embodiment 1

[0021] (1) Bacteria production:

[0022] 1) Peanut Rhizobium: The composition of the liquid medium is 0.08-0.2% (weight / volume) of yeast extract, 0.5-1.5% (volume / volume) of mannitol, 0.05-0.2% magnesium sulfate (weight / volume), 0.1-0.4 % Iron trichloride (weight / volume), 0.05-0.2% sodium molybdate (weight / volume), 0.01-0.1% zinc sulfate (weight / volume), 0.05-0.15% potassium dihydrogen phosphate (weight / volume), 0.08-0.2% calcium chloride (weight / volume), pH 6.6-7.6, sterilized at 121°C for 25-40 minutes. Cool to about 35℃, inoculate peanut rhizobia, the inoculation amount is about 10 per ml of liquid medium 5 -10 6 One peanut rhizobia cultured on a shaker at a speed of 100-180 revolutions per minute. After 48-72 hours, sample the fermentation broth and check that the number of rhizobia reached 20x10 per ml of liquid. 8 At this time, the fermentation is over;

Abstract

The invention provides a special seed coat eco-fertilizer for planting peanuts in red soil and a preparation method and application thereof. The seed coat eco-fertilizer is prepared by the following steps of: uniformly mixing peanut rhizobium, trichodermaviride, bacillus subtilis, phosphobacteria and the like; adding potassium dihydrogen phosphate, zinc sulfate, manganese sulfate, sodium molybdate, magnesium sulfate, carboxymethyl cellulose, sodium alginate and the like, and adjusting pH value to be 6-8; grinding into about 200 meshes to obtain suspension concentrate by using a colloid grinder to obtain the finished product. When in use, the solution of the product is evenly sprayed on the surfaces of peanut seeds; and then, calcium chloride solution is sprayed, and finally, the peanut seeds are dried properly. The product is mainly used for planting peanuts in red soil areas and particularly suitable for peanut continuous cropping, can improve the obstacles in peanut continuous cropping, boost the growth of peanuts, eliminating obstacles in peanut continuous cropping, control peanuts diseases, and improve peanut yield and peanut quality.

Description

1. Technical Field [0001] The invention belongs to the technical field of agriculture, and specifically relates to a special seed coat ecological fertilizer for peanut planting in red soil, and a preparation method and application thereof. 2. Background technology [0002] Red soil is an acid soil with low fertility, which affects the growth of peanuts. Long-term continuous cropping of peanuts is prone to continuous cropping obstacles. Peanuts grow slowly, are prone to disease, low yield, and decline in quality. The large-scale application of chemical fertilizers causes environmental pollution and excessive greenhouse gases. [0003] At present, cropping and intercropping are commonly used in production to solve the obstacles of continuous peanut cropping, but the economic benefits obtained by farmers have declined. At the same time, a large number of chemical pesticides have caused serious environmental pollution and ecological balance damage, and the quality of peanuts has decre...
