Abstract
Seedling agent and its production method are strengthened the invention discloses a kind of green acid adjustment of high-effective microorganism.The present invention cultivates aspergillus niger on PDA solid mediums, is linked into afterwards in seed culture medium, and fermentation obtains seed fermented liquid.Then seed fermentation liquid and the suitable fermentation medium to be seeded that has sterilized aseptically are inoculated with by a certain percentage and continue fermentation after be well mixed, produce the conidia powder of the microorganism.Finally again using turf as carrier, after being mixed with quantitative pyrolkigneous liquid and turfy soil, acidification is carried out.A certain amount of crushing of addition, the nitrogen mixed, phosphorus, potassium and trace element mix and produce the microbial-bacterial fertilizer.The present invention has activating soil, adjusts soil aciditiy, increase soil fertility and gas permeability, and killing pests and suppressing bacteria effect is good, nurturing staff, slow seedling is fast after transplanting, and tiller is early, is that the high yield of paddy rice creates the effect of good condition.It is that stalk recycles offer technical support and the soil-borne disease to multiple kinds of crops seedling stage plays certain preventive and therapeutic effect.
Description
Technical field：
Seedling bacterial manure is strengthened the present invention relates to a kind of micro organism green acid adjustment of agricultural technology field, is that one kind is suitable for a variety of farmings
Seedling agent is strengthened in the green acid adjustment of the solid microbe of thing, belongs to circular agriculture.
Background technology
For many years, in arviculture, the consumption of chemical fertilizer is being continuously increased, and the consumption of organic fertilizer is increasingly
It is few, and crops to the utilization rate of chemical fertilizer only 30% or so, about 70% chemical fertilizer deposition be fixed in soil or with
Rain water runoff is without being absorbed and being utilized by crops in rivers, and which results in soil hardening, environmental pollution, rivers and underground water
Negative nutrient laden is on the rise, and soil organic matter content reduction, fertility declines, and beneficial microorganism living space diminishes in soil,
Quantity is reduced, and the disease-resistant of crops, cold-resistant, drought-resistant ability weaken, and the generation of pest and disease damage is increasingly severe, causes crops quality
Decline, yield reduction.
In recent years, bio-organic fertilizer, composite microbiological fertilizer application it is increasingly extensive, particularly composite microbe fertilizer
Material is rapid to emerge, and this will make China's fertilizer industry enter a brand-new epoch, and composite microbiological fertilizer is applied in agricultural production
Show, in the raising of chemical fertilizer utilization rate, chesson reduces river pollution, culture fertility, nurturing staff, reduction disease pest
Extraordinary effect is suffered from terms of harmful generation, the resistance for strengthening crop.Pyrolkigneous liquid is interior as straw charring byproduct
Containing the gas chromatography matter such as acids, alcohols, phenols, environmental protection and public nuisance free changes soil aciditiy, and antibacterial desinsection, increase soil is organic
The effects such as matter, while depositing into the cycle applications of stalk.
The content of the invention：
