Abstract
The invention provides a technique utilizing forage grasses to treat pig farm sewage, the technique introduces warm-season perennial gramineous forage grasses and cool-season annual gramineous forage grasses for year-round planting and for treating sewage in pig farms; and the produced forage grasses are directly fed to pigs or added into mingled forage by different proportions after pulping for breeding pigs at different stages. The technique combines the pig farm pollution treatment technique and forage grass planting, and rationally utilizes culture wastes to develop the grass industry, change waste into valuables, realize the beneficial cycle of pig raising-biogas slurry-forage grasses, reach zero release of sewage in the breeding industry, and avoid the pollution of sewage to the environment in the breeding industry, and the forage grasses grown on the grassland have advantages of good quality, high output and obviously reduced production cost, and the forage grasses produced by adopting the method are used in animal husbandry, the costs for breeding livestock are also reduced obviously, the sewage treatment in pig farms can be realized, functions of forage grasses in environmental ecological safety and bioremediation can be achieved, and the technique has broad application prospect and outstanding economic benefit and environmental protection value.
Description
Technical field
The invention belongs to the improvement technology of pig farm sewage, more specifically relate to a kind of herbage technique for treating sewage water of pig farm that utilizes.
Background technology
Livestock industry is the strong industry and the mainstay industry of China's rural economy, become increasingly conspicuous with its environmental problem that develops association mutually rapidly, the animal waste discharging has become one of important source of pollution that influence China's environmental aspect improvement, and especially pig farm quantity is many, scale big and the sewage of discharging is many.Current, though many pig farms have been introduced technology such as biogas environmental engineering and have been disposed of sewage, but still there are pollution treatment technology and the pollution treatment engineering reasons such as sewage of can not dissolving fully, the controlling liquid and can not reach qualified discharge fully of its discharging, still contaminate environment causes the nutrition of soil rich long-pending, and soil property is degenerated, polluted air, polluted source and underground water also cause nitrate content to exceed standard.But natural pond liquid is high-quality fertilizer, contain organic 30%～50% in the fertilizer of natural pond, humic acid 10%～20%, nitrogen 0.8%～1.5%, phosphorus element 0.4%～0.6%, potassium element 0.6%～1.2%, natural pond liquid also contains a large amount of each amino acid, VITAMIN, protein, Plant hormones regulators,gibberellins, growth hormone, carbohydrate, nucleic acid and microbiotic simultaneously.Nucleic acid and monose can strengthen the crop drought resistance ability, and free state amino acid can strengthen the crop freezing tolerance, and microbiotic can controlling crop diseases and insect pests.Therefore, the Pollution abatement on pig farm must take to realize the pattern of agricultural development and environment protection doulbe-sides' victory, when realizing Pollution abatement, the pollution treatment behavior itself is brought benefits, and reduces aquaculture production cost and waste water control cost, even brings income.
Summary of the invention
The object of the invention provides a kind of herbage technique for treating sewage water of pig farm that utilizes; Pollution abatement technology in pig farm is combined with the pasture growing industry; rationally utilize and culture waste development grass cultivation; accomplishing turns waste into wealth; realize the benign cycle of " raising pigs-natural pond liquid-herbage "; reach the sewage zero-discharge of aquaculture; environmentally safe; and the herbage quality that the grassland produces is good; the productive rate height; cost significantly lowers; the herbage of adopting this method to produce is used for livestock industry; the cost of raise livestock also significantly reduces; can realize the pig farm waste water control, reach the effect of herbage in environmental ecology safety and biological restoration, have broad application prospects and significant economic benefits and environment protection value.
The herbage technique for treating sewage water of pig farm that utilizes of the present invention mainly is: introduce the plantation of season type study of perennial forage grasses and cold-season-type annual gramineae herbage anniversary, the sewage that the pig farm of dissolving produces; The herbage of producing directly feeds pigs or adds the pig that different ratios is used to raise different steps in the mixed feed through making beating back.
Remarkable advantage of the present invention is:
1) the present invention is directed to the specific requirement of China's specific national conditions and modern agricultural development, when realizing the pig farm Pollution abatement, it is combined with the pasture growing industry, rationally utilize and culture waste development grass cultivation, accomplishing turns waste into wealth, realize the benign cycle of " raising pigs-natural pond liquid-herbage ", reached the sewage zero-discharge of aquaculture, avoided pig farm sewage discharge pollution on the environment.
2) the present invention is best reasonably combined by what study pig farm scale, sewage treatment process and plant husbandry scale for many years clear and definite, all absorbed by this reasonably combined natural pond liquid that produces after pig farm sewage is by anaerobically fermenting of can realizing, reach the sewage zero-discharge of aquaculture by herbage.
3) pasture growing technological sciences of the present invention are reasonable, and the herbage quality that the grassland produces is good, output is high and cost significantly reduces.Hybrid Chinese pennisetum general planting method is need execute urea 320kg/hm after cradling at every turn after deliberation
2, the herbage crude protein content of its production is 11.80%, bright careless output is 110.82t/hm
2As long as, need not use urea with the present invention and use the hybrid Chinese pennisetum crude protein content of natural pond liquid production and can reach 13.78%, bright careless output can reach 225.12t/hm
2, improve 16.78% and 103.14% than ordinary method respectively, the per hectare meadow can reduce the urea usage quantity and reach 2.56～3.20t, and 4300～5400 yuan/hm reduces production costs
2
4) herbage of the present invention's production is used to develop animal husbandry, and when widening feed resource, can reduce feeding cost and increase economic efficiency.The hybrid Chinese pennisetum making beating back employing addition of producing with the present invention is that 0.5kg/ .d method added in the ration formulation of fattening pig after deliberation, and the fattening pig day weight gain and the economic benefit of only feeding ration formulation than ordinary method can improve 5.17% and 8.43% respectively.As seen the present invention utilizes herbage to realize the pig farm waste water control; the effect of performance herbage in environmental ecology safety and biological restoration; turn waste into wealth simultaneously; reach the recycle of herbage; reduce the herbage production cost; improved the economic benefit of pig industry, had broad application prospects and significant economic benefits and environment protection value.
