Abstract
The invention discloses an ecological organic fertilizer for restoring soil balance. The fertilizer is an organic, inorganic, carbon-based and microbial integrated fertilizer capable of restoring ecological balance of soil, and increasing yield of crops. The fertilizer is prepared from the following components: 20%-32% of urea, 15%-25% of monoammonium phosphate, 15%-22% of a carbon-based fertilizer, 20%-30% of potassium chloride or potassium sulfate, 3%-5% of vegetable organic matters, 3%-8% of biological humic acid, 2%-5% of biological amino acid, 1%-3% of medium and trace nutrients and 1%-2% of beneficial biological bacterium. The physical characteristics of soil can be improved after the ecological organic fertilizer is continuously used; the ecological organic fertilizer especially has a good effect on soil adopting straw manure for many years, the surface area of the soil is increased, the soil structure is loose, lots of silk fossa-shaped structures are formed and the soil hardening is alleviated; a food chain of earthworm is restored by humus generated by combination of a lot of beneficial microorganisms and organic matters (including straws) in soil; and the ripping expert (earthworm) turns back to the farm, so that the ability of soil in regulating and controlling water is increased; and the drought resistance and the flood resistance of the crops are significantly improved.
Description
Technical field
The present invention relates to a kind of agricultural fertilizer, be specifically related to a kind of ecological organic fertilizer recovering soil balance.
Background technology
At present, China's agriculture production mainly relies on chemical fertilizer, from the beginning of the eighties to this day, fertilizer amount is increasing, utilization ratio reduces gradually, agricultural prods Quality Down, trace it to its cause, organism in soil, middle amount, trace element and beneficial organism bacterium reduce day by day, soil ecology serious unbalance, many unfavorable factors are brought to agriculture production, such as: beneficial microorganism disappearance has interrupted earthworm food chain, earthworm this " loosen the soil expert " is from soil, soil-borne disease has lacked killer's (beneficial microorganism) and rampant, this just means soil compaction, transparency, the ability of regulation and control of water is reduced, crop root point component and length obviously weaken, drought resisting, waterlogging-resistant ability declines.Have statistics, soil fungi venereal disease evil causes global wheat, corn, the large crop failure loss of paddy rice three up to 60,000,000,000 dollars every year.(Agence France-Presse, Paris on April 11st, 2012) fungi has toxicity, and the vigorous spore dispersal of vitality, these spores can by Feng Heshui, and tillage machinery and personnel, be carried to Anywhere.As: the 2012 many local wheatlands in Nian Chun Zhumadian prefecture, Henan province city there occurs yellow mosaic disease viral disease, it carries caused by virus by Polymyxa Graminis, also has southern banana yellowtop after big area occurs, banana still can not be planted in 30 years in this plot, all can not accomplish that As the medicine took effect, the symptoms lessened in the world at present, it is by long-term effect crop yield.
Summary of the invention
The object of the invention is the problem for soil ecology serious unbalance in current agriculture production, a kind of microorganism, organic and inorganic, charcoal base ecological fertilizer are provided, this fertilizer can help to recover soil ecology balance, improve utilization rate of fertilizer, make more than fertilizer metabolism cycle stretch-out to year, reduce irrigation amount, reduce fertilizer in soil evaporation and under ooze, reduce the pollution to air and surface water, achieve the object of water saving, energy-conservation, ecological, environmental protection, high yield, high-quality agricultural.
For achieving the above object, the present invention adopts multiple beneficial bacterium to be inoculated in vegetalitas organism (tangerine bar or animal excrement), be equipped with lower inorganic again, charcoal base manure component, microbial organic fertilizer is generated by the aerobic abundant fermentation of strict temperature control, i.e. a kind of organic biofertilizer recovering soil ecology balance, this fertilizer is made up of following component: urea 20 ~ 32%, monoammonium phosphate 15 ~ 25%, charcoal base manure 15 ~ 22%, Repone K or potassium sulfate 20 ~ 30%, vegetalitas organic matter 3 ~ 5%, biological humic acid 3 ~ 8%, biological amino acid 2 ~ 5%, in, trace element 1 ~ 3%, beneficial organism bacterium 1 ~ 2%.
Based on technique scheme, described organic biofertilizer is made up of following component: urea 23%, monoammonium phosphate 17%, charcoal base manure 18%, Repone K or potassium sulfate 25%, vegetalitas organic matter 4%, biological humic acid 5%, biological amino acid 4%, medium trace element 1.5%, beneficial organism bacterium 1.5%.
Based on technique scheme, described middle and trace element is: calcium, magnesium, sulphur, silicon, iron, copper, manganese, molybdenum, zinc, boron.
Based on technique scheme, described calcium, magnesium, sulphur, silicon, iron, copper, manganese, molybdenum, zinc, boron ratio are: 1:1:1:1:2:1:1:1:1:3.
Based on technique scheme, described charcoal base manure is biological powdered carbon.
Based on technique scheme, described beneficial organism bacterium is made up of fungus and bacterium, and fungus and bacterium ratio is 1:1.
Beneficial effect of the present invention: Eco-fertilizer of the present invention is at nitrogen, phosphorus, on the basis of potassium, add organic matter, charcoal base manure, in, trace element and beneficial microorganism, continuous use, soil physical property can be changed, especially to the soil adopting straw-returning for many years, effect is better, soil surface area can be made to increase, short texture, go into various silk nest shape structures, alleviate soil compaction, organism (comprising stalk) in a large amount of beneficial microorganisms and soil combines, the soil ulmin produced, repair the food chain of earthworm, the expert (earthworm) that makes to loosen the soil turns back to field, the current whole world all knows that wormcast is the best fertilizer of plant, it contains 300 multiple beneficial microorganisms and 18 seed amino acids, the beneficial microorganism material that metabolism goes out in survival and reproduction process is commonly called as " jelly ", participate in the link between soil particle, thus add the ability of regulation and control of soil to water, make crop drought resistance, Flood resistance significantly improves, the metabolite that beneficial microorganism produces is again the base substance of crop root branch and growth just, the branch amount of root system and length are increased.Beneficial microorganism also makes phosphorus, potassium and the medium trace element be fixed in soil be decomposed, due to the participation of medium trace element, accelerate crop metabolism process, improve crop to nitrogen, phosphorus, the absorbing of potassium, add the accumulation of nutritive substance, thus improve output.Model field shows: it is 78 yuan that model field every mu is increased input, this season volume increase 150-200 jin wheat, and it is more worthwhile to it is generally acknowledged, but it can increase production more than 10% to crop of lower season, once use and still have obvious drought-resistant ability to wheat next year, except economic benefit, social benefit is to make the soil restoration eubiosis, improve utilization rate of fertilizer, reduce wheat sowing quantity, irrigation times, reduce the usage quantity of agricultural chemicals, reduce surface water pollution, an also healthy the earth, also mankind's health.
