Problems solved by technology

But as far as the current situation is concerned, due to the influence of various subjective and objective factors, the emergence of various diseases and insect pests in the process of planting rapeseed in some areas of our country has greatly affected the yield of rapeseed.
[0003] The main diseases and insect pests of rapeseed include sclerotinia, downy mildew, white rust, rape beetle, weevil, aphid, etc. Farmers have always used pesticide spraying methods to prevent and control the planting, but with the increasing resistance of insect pests In the long run, it will form a vicious circle, which is not conducive to the cultivation of rapeseed and the improvement of quality, and will cause greater damage to the environment.
[0004] For this situation, no effective solution has been proposed in the prior art

[0045] Preparation of Trichoderma viride spore powder:

[0046] a slope culture: activate Trichoderma viride on a PDA slope, inoculate it into potato glucose liquid culture medium after activation and cultivate it for 36 hours to obtain Trichoderma liquid seed liquid;

[0047] b Fermentation tank culture: 1 ton fermenter tank is prepared with potato glucose culture medium according to the filling volume of 60%, the fermentation tank and the air pipeline are sterilized, and the inoculum volume is 2% for inoculation and culture, and the culture condition is that the rotation speed is 120- 140r / min, culture temperature 26±2°C, ventilation rate 3kg, culture for 48 hours and stop fermentation to obtain Trichoderma fermented seed liquid;

[0048] c solid fermentation spore production: mix the bran and corn flour in a ratio of 1:1, adjust the moisture to 40%, sterilize to obtain a solid medium, and after the solid medium is cooled, ferment the seed liquid obtained in step b Inoculate ...

Embodiment 1

[0052] A special fertilizer for rape is prepared from the following raw materials in parts by weight:

[0053] 20 parts of soybean meal, 25 parts of tung seed meal, 41 parts of pig manure, 6 parts of lotus pod, 7 parts of walnut green skin, 0.2 parts of fermented bacteria agent, and 1 part of compound bacteria agent;

[0054] The special fertilizer for rapeseed is prepared by the following method:

[0055] 1) Primary fermentation: crush tung seed meal, lotus pod, and walnut green husk into small pieces of 1-2 cm in size, as fermentation raw materials, add the fermentation raw materials, pig manure and soybean meal together with fermentation bacteria agent and mix evenly, pile and retting for 25 days, During the stacking process, the temperature is kept at 55-70°C for 10-20 days. When the temperature of the fermentation pile drops below 45°C and the moisture content drops below 45%, the stacking is stopped to obtain fermented organic fertilizer.

[0056] 2) Secondary fermentat...

Embodiment 2

[0058] A special fertilizer for rape is prepared from the following raw materials in parts by weight:

[0059] 15 parts of soybean meal, 10 parts of tung seed meal, 7.5 parts of pig manure, 8 parts of lotus pod, 8 parts of walnut green skin, 0.1 part of fermentation agent, 1.5 parts of compound agent;

[0060] Its preparation method is the same as that of Example 1, and the composting time of the organic fertilizer is 28 days.

Abstract

The invention relates to special fertilizer for rapes. The special fertilizer is prepared from the following raw materials in parts by weight: 15 to 25 parts of soybean meal, 10 to 35 parts of tung seed meal, 24 to 65 parts of pig manure or cattle manure, 5 to 8 parts of lotus seed pot, 5 to 8 parts of walnut green husk, 0.1 to 0.3 part of a fermentation bacterium agent and 0.5 to 1.5 parts of a compound bacterium agent, wherein the fermentation bacterium agent contains bacillus, fungi, actinomyces, hemicellulase, cellulase and laccase; the compound bacterium agent contains bacillus amyloliquefaciens, bacillus megaterium and trichoderma viride. According to the special fertilizer provided by the invention, used raw materials are agriculture wastes; after being fermented, the raw materialscontain a lot of nutrients including organic matters, nitrogen phosphorus potassium and the like, and also contain various amino acids and antibacterial substances; nutrient substances can be providedfor the rapes and diseases and insect pests of the rapes are prevented; after organic raw materials are fermented, the compound bacterium agent is added to carry out secondary fermentation; microorganisms are greatly proliferated in organic fertilizer; meanwhile, metabolic products are produced; sclerotiniose, downy mildew and white rust of the rapes can be inhibited very well.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a special fertilizer for rapeseed and its preparation method and application. Background technique [0002] As an important oil crop in our country, the cultivation of rapeseed can not only provide people with rich edible oil, but also help farmers increase their income and improve their living standards. But as far as the current situation is concerned, due to the influence of various subjective and objective factors, the emergence of various diseases and insect pests in the process of rapeseed planting in some areas of my country has greatly affected the yield of rapeseed. [0003] The main diseases and insect pests of rapeseed include sclerotinia, downy mildew, white rust, rape beetle, weevil, aphid, etc. Farmers have always used pesticide spraying methods to prevent and control the planting, but with the increasing resistance of insect pests If the amount of pesticides is ...
