Abstract

The present invention provides a kind of livestock and poultry feces and returning to the field method is coupled with stalk, the zymophytes such as cellulase, protease, lipase, saccharomycete, taste removal bacterium will be added in Animal fecal pollution, shorten excrement dirt fermentation time, using livestock and poultry feces as the production of Straw decomposing bacterium, breeding, the carrier applied, decomposer quantity increases by 8 20 times after fermentation, in the presence of protease, lipase, the discharge of excrement dirt fermentation process odorless.Livestock and poultry feces returning to the field and stalk mechanical crushing returning to the field are combined, livestock and poultry feces in excrement dirt in the presence of Mixed Microbes, accelerate rotting for stalk as crop material accelerator.Compared with single stalk mechanical crushing returning to the field method, hence it is evident that shorten stalk and rot the time, it is not perishable to solve straw-returning, and seed sprouting problem is influenceed during sowing；Crumb structure in soil can be obviously improved, improves soil with organic matter, nitrogen, phosphorus, potassium content.Compared with stalk crushes pile fermentation time field method, method is simple, simplifies using link, it is easier to operates, saves substantial amounts of manpower and materials.

Description

A kind of livestock and poultry feces couple returning to the field method with stalk

Technical field

The present invention provides a kind of livestock and poultry feces and returning to the field method is coupled with stalk, belongs to field of agricultural production technologies.

Background technology

The annual stalk in China produces nearly 700,000,000 tons, occupies first place in the world.Because stalk comprehensive utilization rate is low so that stalk turns into " residue " thing in rural area, Open Burning Crop Residue is brought up, pollute environment.Straw-returning is to solve stalk to remain as fertilizer utilization Effective ways that are remaining, improving soil environment condition.It is perishable because main component is cellulose and hemicellulose in stalk, Constrain straw-returning and make fertilizer utilization.At present, Straw Crushed for Reclaiming method has two kinds：One kind is that stalk mechanical crushing is deep Turn over and sternly bury returning to the field, stalk is degenerated using the microorganism in soil and decomposed, the method is due to Soil Microorganism amount, the shadow of moisture Ring, the stalk corruption decomposition of returning to the field is slower, and the time for rotting to need completely is longer, particularly the weather conditions of northern area, shadow Ring spring sowing and emergence.It is after stalk is crushed that another stalk, which returns field mode, is doped into appropriate lime and human and animal excreta, stack retting Fermentation, go bad in the environment of semi-oxidized semi-reduction and rot, further take out and impose on farmland and make Fertilizer application, such a method is due to stalk Transport and administration need to consume substantial amounts of man power and material, with the reduction of rural laborer, are seldom used.

With the development of China's livestock and poultry breeding industry, a large amount of excrement and sewage turn into important dirt caused by livestock and poultry cultivation Dye source.Livestock and poultry feces processing turns into the important environmental problem that people increasingly pay close attention to.The processing of livestock and poultry feces returning to the field utilizes Main way, returning to the field mode are mainly compost direct returning to farmland and the indirect returning to the field of organic granular fertilizer are made, mainly dry method returning to the field profit With, and liquid dung is largely discharged, and causes environment and underground water pollution.

The content of the invention

The invention provides a kind of livestock and poultry feces to couple returning to the field method with stalk, has both solved plant's Animal fecal pollution fermentation Time is grown, odor pollution problem, simplifies livestock and poultry feces fermentation, using link, improves fermenting speed.Solve stalk again to return Field is not perishable, influences seeding quality problem.Excrement dirt mixed liquor is directly applied to field using equipment is sprayed, makes excrement is dirty to utilize Simplify.

A kind of livestock and poultry feces of the present invention couple returning to the field method with stalk, comprise the following steps：

1）By cellulase 0.5-1 parts, aspergillus oryzae 0.3-0.5 parts, protease 0.1-0.3 parts, lipase 0.3-0.5 Part, lactic acid bacteria 0.2-0.5 parts, actinomyces 0.2-0.5 parts are added to the water by above-mentioned parts by weight, are stirred；

2）Mixed Microbes are poured into feace storing pool, add water puddle make feces of livestock and poultry dry matter content 80-100 parts reach 20% ~ 40%, fermented mixture 10-20 days, livestock and poultry feces are made；

3）Before, water-loss reducer 0.6-1 parts are added into livestock and poultry feces；

4）While crop harvesting, by 2-5 centimetres of stalk mechanical crushing length in farmland, it is laid in furrow；

5）Livestock and poultry feces mixed liquor is uniformly sprayed on the stalk of crushing with equipment is sprayed, mixed liquor is covered straw Stalk；

6）Former ridge Qi Xin ridges are broken, livestock and poultry feces and stalk are embedded in soil, then suppressed；

7）Described livestock and poultry feces amount of application is 30-50 tons/hectare.

A kind of livestock and poultry feces of the present invention, it is characterised in that be made of following raw materials by weight portion ratio：

Feces of livestock and poultry 80-100 parts, cellulase 0.5-1 parts, aspergillus oryzae 0.3-0.5 parts, proteinase-10 .1-0.3 parts, fat Enzyme 0.3-0.5 parts, lactic acid bacteria 0.2-0.5 parts, actinomyces 0.2-0.5 parts.

The present invention is using livestock and poultry feces as the production of Straw decomposing bacterium, breeding, the carrier applied.Livestock and poultry feces couple with stalk Returning to the field, in excrement dirt under a variety of fermentations, decomposer effect, accelerate stalk to rot, shorten stalk and rot the time.

The positive effect of the present invention is：It is creative will be added in Animal fecal pollution cellulase, protease, lipase, The zymophytes such as lactic acid bacteria, actinomyces, shorten excrement dirt fermentation time, using livestock and poultry feces as the production of Straw decomposing bacterium, breeding, apply Carrier, in the presence of protease, lipase, excrement dirt fermentation process odorless discharge.Adding water-loss reducer keeps field excrement dirty With stalk moisture content, growth, viability environment are provided for fermentation decomposer, is rotted beneficial to stalk fast decoupled.The technology is by animal dung Dirty returning to the field combines with stalk mechanical crushing returning to the field, and livestock and poultry feces mix as crop material accelerator in excrement dirt In the presence of bacterium, accelerate rotting for stalk.Compared with single stalk mechanical crushing returning to the field method, hence it is evident that when shortening stalk rots Between, it is not perishable to solve straw-returning, and seed sprouting problem is influenceed during sowing；The technology can be obviously improved granule knot in soil Structure, improve soil with organic matter, nitrogen, phosphorus, potassium content.Compared with stalk crushes pile fermentation time field method, method is simple, simplifies Apply link, it is easier to operate, save substantial amounts of manpower and materials.
