A kind of complex micro organism fungicide for soil conditioning
Technical field
The present invention relates to a kind of new soil recuperation agent, belong to agriculture microbial technique and fertilizer field.
Background technology
Soil is crop growth " parent ", and soil fertility comprises Chemical fertility, physics fertility, organic fertility and biological fertility.Because use of a large amount of, excessive and unscientific fertilization mode, weedicide and agricultural chemicals for a long time etc. causes soil fertility structure destroyed, show as the excessive use of macroelement, cause in the passivation of the accumulation of soil nitrite, excessive phosphate fertilizer and soil beneficial microorganism to reduce or suppressed, soil aggregate is destroyed, soil compaction, soil biological fertility descends, and the soil organism reduces, and four of soil fertility are all destroyed.Long-term continuous cropping continuous cropping plantation, also make farm crop in soil accumulate in a large number from poisonous substance matter.Edatope is destroyed, making the agriculture production means of agricultural production drop into marginal efficiency significantly descends, occurred that farm crop produce Soil-sickness Problem simultaneously, dead seedling and early ageing phenomenon are serious, in plant growing process, disease and pest is occurred frequently, directly affect crop yield reduction, quality decline, and finally caused food safety hidden danger very serious.This situation has entered into the vicious cycle of " Soil structure is destroyed-crop growth is influenced-disease and pest is occurred frequently-fertilizer and agricultural chemicals usage quantity and frequency increasing-edatope further worsen ".Only have edatope is adjusted and is only deal with problems basic.Therefore, how conditioned soil, recover soil fertility, becomes the major issue of current agriculture production.
Microorganism is the biology that a unique class can work with live body in fertilizer, and it has special metabolism synthesis capability.The effect of microorganism in promoting soil fertility is by the fact of scientific and technological circle and growing industry acceptance.The use of agricultural microorganism fertilizer, directly supplement the soil probiotics on the one hand, recovers soil biological fertility; Some specific floras can decompose the nitrite in soil and activate the oxious components such as the phosphate fertilizer be passivated, the toxic substance in decomposition and passivation soil, heavy metal simultaneously, adjust the Chemical fertility of soil; Microorganism and meta-bolites thereof can be nursed one's health soil aggregate and soil acidity or alkalinity, make the material resources fertility of soil be adjusted, organic one side in composite microbe fertilizer is the nutrition carrier of microbial activities, also fast and effeciently supplements organic fertility of soil simultaneously; Microbial metabolites further suppresses and kills harmful bacteria in soil, promotes crop root, the crop phylactic agent is provided, and directly for crop growth, escorts.
The adjustment that the present invention is directed to four fertility of soil is required, and the microorganism of choice for use has: vinelandii, root nodule bacterium, phosphate-solubilizing bacteria, potassium bacterium, actinomycetes, sporeformer, pythium oligandrum etc.Humic acids itself just has good soil conditioning effect, the combination of humic acids and microorganism, on the one hand by the participation of microorganism, increased the effect of humic acids conditioning soil, humic acids, for microorganism provides existence required nutrition, has also increased substantially the vitality of microorganism in soil simultaneously.
Summary of the invention
The present invention releases a kind of complex micro organism fungicide for soil conditioning, and its main component is by actinomycetes, vinelandii, phosphorus bacteria, potassium bacterium, genus bacillus, pythium oligandrum, then is aided with xanthohumic acid, fertilizer and middle trace element.Complex micro organism fungicide of the present invention can be nursed one's health the soil physical chemistry shape, but supplementary soil probiotics kills the pathogeny bacterium, supplements native organic matter and middle trace element, decompose the nitrogen phosphorus potassium in soil, the conditioning soil acidity or alkalinity, thereby reach the effective conditioning to soil, make soil be more suitable for the growth needs of farm crop.
The present invention realizes by following technical solution:
1. feed composition is as follows by weight percentage:
Actinomycetes 3-20%, vinelandii 2-15%, phosphorus bacteria 2-15%, potassium bacterium 2-15%, genus bacillus 3-20%, pythium oligandrum 2-15%, xanthohumic acid 3-20%, fertilizer 35-55%, ferrous sulfate 0.3-2%, sal epsom 0.3-2%, manganous sulfate 0.3-2%, zinc sulfate 0.3-2%, copper sulfate 0.3-2%.
The preferred feedstock compositions in weight percentage is:
Actinomycetes 5-15%, vinelandii 3-10%, phosphorus bacteria 3-10%, potassium bacterium 3-10%, genus bacillus 5-15%, pythium oligandrum 3-10%, xanthohumic acid 5-15%, fertilizer 40-50%, ferrous sulfate 0.5-1.5%, sal epsom 0.5-1.5%, manganous sulfate 0.5-1.5%, zinc sulfate 0.5-1.5%, copper sulfate 0.5-1.5%.
The optimum feed stock compositions in weight percentage is:
Actinomycetes 10%, vinelandii 5%, phosphorus bacteria 5%, potassium bacterium 5%, genus bacillus 10%, pythium oligandrum 5%, xanthohumic acid 10%, fertilizer 45%, ferrous sulfate 1%, sal epsom 1%, manganous sulfate 1%, zinc sulfate 1%, copper sulfate 1%.
2. process for producing:
The first step: by actinomycetes, vinelandii, phosphorus bacteria, potassium bacterium, genus bacillus, pythium oligandrum is mixed and stir;
The living bacteria count of every kind of bacterium all needs>=and 1 * 10
10Individual/gram.
Second step: stir after xanthohumic acid, fertilizer, ferrous sulfate, sal epsom, manganous sulfate, zinc sulfate, copper sulfate are mixed, then high-temperature sterilization;
The 3rd step: the mixture that the first step, second step are made is mixed together, and stirs, and then at 25-30 ℃, aerobic, condition of normal pressure bottom fermentation 24-48 hour, to increase viable count and microorganism derivative, is the quantity of meta-bolites.
The 4th step: the product that the 3rd step is obtained obtains the finished product to moisture at 18-30% at 40 ℃ of oven drying at low temperatures.
The finished product are living bacteria count >=500,000,000/gram, the pulvis of Ph value 4.5-6.5.
Embodiment
Embodiment is to produce 1 ton of complex micro organism fungicide
Proportioning raw materials is as follows:
In above raw material, the living bacteria count of every kind of bacterium all needs>=and 1 * 10
10Individual/gram, fertilizer organic matter>=70%.
Process for producing:
The first step: by actinomycetes, vinelandii, phosphorus bacteria, potassium bacterium, genus bacillus, pythium oligandrum is mixed and stir;
Second step: stir after xanthohumic acid, fertilizer, ferrous sulfate, sal epsom, manganous sulfate, zinc sulfate, copper sulfate are mixed, then high-temperature sterilization;
The 3rd step: the mixture that the first step, second step are made is mixed together, and stirs, and, 25-30 ℃, aerobic, condition of normal pressure bottom fermentation 48 hours, to increase viable count and microorganism derivative, is then the quantity of meta-bolites.
The 4th step: the product that the 3rd step is obtained at 40 ℃ of oven drying at low temperatures to moisture 20%, then be crushed to 20 orders and obtain the finished product.
The finished product are living bacteria count >=500,000,000/gram, organic >=30%, the pulvis of Ph value 4.5-6.5.Product use-pattern of the present invention is soil application, and using time and usage quantity are the 10-20 kilogram for coordinating base fertilizer to spread fertilizer over the fields every mu of usage quantity, and ditch spread, the every mu of usage quantity of spreading manuer in holes are the 5-10 kilogram.
