Problems solved by technology

[0003] After retrieval, the relevant patents in this field are: 1. Chinese patent application 02133713.6 discloses a microbial fertilizer agent that directly decomposes straw into fertilizer and its production process and application method. The invention only uses spore-producing functional bacteria to treat straw Obviously, the complex composition of straw is not fully considered, so that the degradation is not sufficient, the fertility of straw returning to the field is not fully released, and the application effect is not good
2. The microbial starter of Chinese patent application 200410065178.0 discloses a microbial starter for the treatment of organic matter from biological sources, especially livestock and poultry breeding waste, crop straw, etc., from the microbial components of the invention and the enzymes in the attached table Live analysis, the microorganisms used mainly degrade organic matter such as feces of livestock and poultry breeding industry, and the degradation effect on crop straw with high cellulose content is not obvious
3. Chinese Patent Application No. 200810033507.1 discloses a method for producing soil bio-fertilizer by using a compound starter to ferment livestock and poultry manure and crop stalks. The invention requires the stalks to be dried to a moisture content of 10% to 15% and crushed to below 20 mesh , put into double-layer black plastic bags for anaerobic fermentation, the operation process is complicated, which increases the production cost and is not conducive to popularization
4. Chinese Patent Application No. 200710054454.7 discloses a method of using straw microorganisms to prepare soil conditioner, because it requires the straw to be crushed to less than 2mm, and requires high-temperature steam explosion and microwave treatment, so the invention has high production cost, complicated operation, and no Good for promotion

Embodiment 1

[0033] Embodiment 1, (taking corn stalk as main raw material, summer production is example)

[0034] Step 1: Chop 1,500 kg of fresh corn stalks and 500 kg of fresh weeds in the field to 1-3 cm, moisten the raw materials with clean water, and make the water content reach 70%, mix well and compost; the internal temperature reaches 70°C Afterwards, the compost was rotted for 3 days, during which it was turned every day to achieve the purpose of removing some bacteria and pathogens carried by the straw.

[0035] Step 2: Spread out and cool down naturally to 25°C to 30°C, add 25 kg of dipotassium hydrogen phosphate, 15 kg of calcium nitrate and 8 kg of urea according to the dry weight of the straw, and mix well.

[0036] Step 3: Stir in 150 kg of solid microbial agent of Group A (total bacterial density 5×10 9 each / gram, the adsorbent accounts for 75%), mix well and accumulate fermentation, the accumulation thickness is not more than 80cm, the control temperature is not more than ...

Embodiment 2

[0039] Embodiment 2, (with wheat straw as main raw material, summer production is example)

[0040] Step 1: Chop 800 kg of wheat straw and 200 kg of field weeds to 1-3 cm, moisten the raw materials with clean water, and make the water content reach 65%, mix well and compost; after the internal temperature reaches 70°C, The composting lasted for 5 days, during which it was turned every day to achieve the purpose of removing some bacteria and pathogens carried by the straw.

[0041] Step 2: Spread out and cool down naturally to 25°C-30°C, add 20 kg of dipotassium hydrogen phosphate, 10 kg of calcium nitrate and 10 kg of urea, and mix well.

[0042] Step 3: Stir in 150 kg of Group A liquid bacterial agent (total bacterial density 10×10 9 per gram, the protective agent is 1.5%), pile up and ferment after mixing well, the pile up thickness is not more than 80cm, the control temperature is not more than 40 ℃, after 7 days, mix in 70 kg of solid bacterial agents of group B (total ba...

Embodiment 3

[0045] Embodiment 3, (taking corn stalk as main raw material, production in winter is example)

[0046] Step 1: Chop 800 kg of corn stalks and 200 kg of rice straw to 1-3 cm, moisten them with clean water, and make the water content reach 75%, mix well and then compost; after the internal temperature reaches 65°C, compost for 10 Days, during which the stirring was done 5 times to achieve the purpose of removing some bacteria and pathogens carried by the straw.

[0047] Step 2: Spread and cool down naturally to 30°C to 35°C, add 25 kg of dipotassium hydrogen phosphate, 15 kg of calcium nitrate and 10 kg of urea, and mix well.

[0048] Step 3: Stir in 100 kg of solid bacterial agent of Group A (total bacterial density 20×10 9 per gram, the adsorbent accounts for 55%), pile up and ferment after mixing well, the pile up thickness is no more than 80cm, the control temperature is no more than 40°C, and after 8 days, mix in 80 kilograms of liquid bacterial agents of group B (total b...

Abstract

The invention provides a preparation method of soil moisturizing bio-fertilizer. The composite microorganism bactericide adopted in the invention comprises an A group bactericide and a B group bactericide, and fermentation preparation is completed by smashing straws, composting and secondary piling fermentation. Compared with the prior art, the invention has simple preparation technique without needing large mechanical equipment, simple and practical method, wide raw material source, and low cost, solves the difficulty in straw treatment, and realizes recycling of resources; the inventive soil moisturizing bio-fertilizer has strong water absorptivity which is increased by over ten times, good moisture retention property to soil, and can eliminate soil hardening and promote root system to grow, improve content of organic matter in soil by 1-1.5 times, reduce dosage of fertilizer by over 35% resulting in planting in the next season without applying fertilizer, adjust soil micro-ecological environment, and reduce occurrence of plant diseases and insect pests and has no putrefactive odor.

Description

technical field [0001] The invention belongs to the technical field of soil moisture retention and biological fertilizer, and in particular relates to a preparation method of soil moisture retention biological fertilizer containing compound microorganisms. Background technique [0002] In my country, with the increase of grain production, the amount of straw is increasing, while the utilization of straw is relatively decreasing, and a large amount of straw is discarded and burned randomly, which not only wastes resources, but also causes the content of soil organic matter to decrease and the micro-ecological environment to deteriorate. , there is a trend of soil compaction, water storage performance reduction, and agricultural product quality decline. Data show that crop straws contain a large amount of organic matter, nitrogen, phosphorus, potassium and trace elements. One hundred kilograms of fresh straws is equivalent to 2.4 kilograms of nitrogen fertilizers, 3.8 kilograms...
