Anti-disease composite microbial fertilizer specially-used for American ginseng and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizers and particularly relates to an anti-disease composite microbial fertilizer specially-used for American ginseng and also relates to the preparation method of the microbial fertilizer. The microbial fertilizer includes furfural residue, cassava residue, decayed cow dung, lignite humic acid, plant ash, tea residue, clay, mineralized yellow-brown potassium humate and a composite probiotic agent. The microbial fertilizer is balanced in nutrients and is abundant in microelements and can effectively increase productivity and improve fertility level of soil. The added composite probiotic agent can significantly inhibit the main diseases of the American ginseng, such as cylindrocarpon destructans diseases, root rot, damping off, black spot and the like. By means of the composite microbial fertilizer, the yield of the American ginseng is increased by 30-35% effectively and diseases rate is reduced by more than 90%. The fertilizer, when being used for long time, can effectively improve soil. The fertilizer is long-acting in fertilizer efficiency, achieves the effects in the whole growing period of American ginseng, and also has the effect of improving the quality of the American ginseng.

Description

technical field

[0001] The invention belongs to the technical field of fertilizers, and in particular relates to a special disease-resistant compound microbial bacterial fertilizer for American ginseng, and also relates to a production method of the special disease-resistant compound microbial bacterial fertilizer for American ginseng. Background technique

[0002] American ginseng is native to North America. It is a precious Chinese herbal medicine with high medicinal and economic value. It has formed four major climatic cultivation areas in my country. In these cultivation areas, the decline in soil fertility and disease problems are severely restricted. The development of American ginseng industry.

[0003] American ginseng is a perennial plant with a strong avoidance of land and obvious obstacles to continuous cropping. It is mainly manifested in soil degradation, reduced fertility and vulnerability to various diseases. Up to now, most of them have dealt with this situati...

Embodiment 1

[0059] The preparation method of the special disease-resistant compound microbial bacterial fertilizer for American ginseng comprises the following steps:

[0060] (1) Preparation of compound microbial agent:

[0061] Preparation of Bacillus polymyxa inoculum: inoculate the Bacillus polymyxa strain into a sterilized fermenter, the fermentation medium is: corn starch 0.80-1.50%, yeast extract 0.01-0.06%, magnesium sulfate 0.05-0.15%, Manganese sulfate 0.006-0.012%, pH6.8-7.2, fermentation conditions: initial aeration ratio is 0.9-1.1:0.5, culture temperature 35-40°C, stirring speed 100-200rpm, dissolved oxygen not less than 30%, pH The value is not lower than 6.5, and the stirring culture is 6-8h, so that the viable bacteria content reaches 10 10 pfu / mL, add disodium hydrogen phosphate and calcium chloride to the fermented liquid for flocculation. After the flocculation is completed, the plate and frame filter method is used to obtain the sludge. The sludge is dried at 45-50°C...

Embodiment 2

[0139] 38.5 parts of furfural residue, 36.2 parts of cassava residue, 15.4 parts of decomposed cow dung, 16.9 parts of lignite humic acid, 13.5 parts of plant ash, 6.8 parts of tea dregs, 7.1 parts of clay, 2.4 parts of mineralized After the yellow-brown potassium humate is mixed evenly according to the above ratio, add 90 parts of water and mix to obtain the base fertilizer, and insert the composite microbial inoculum according to the mass ratio of the base fertilizer and the composite microbial inoculum to 300:1, and mix again. Hold the mixed fertilizer tightly until there is water without dripping, stack the mixed fertilizer in a greenhouse at 37°C to ferment for 2 days, turn it upside down once a day, and pile it up for 3 days to ferment to 45°C to obtain the special disease-resistant compound microbial fertilizer for American ginseng;

[0140] The composite microbial agent is composed of Bacillus colloidus powder, Bacillus natto powder, Bacillus megaterium powder and Trich...
