Description
Technical field
The present invention relates to a kind of bulk blended fertilizer, be specifically related to a kind of bulk blended fertilizer of preventing and treating soil-borne disease and preparation method thereof.
Background technology
In recent years, Grain in China output increase year after year, vegetable supply is also more and more rich and varied, and this allows people enjoy the well-fed and well-clothed life after the reform and opening-up.But a lot of local when pursuing the grain yield increase, ignored the ability to accept of soil, continue to increase the consumption of the chemical such as chemical fertilizer, agricultural chemicals, weedicide.Because long-term a large amount of unreasonable use chemical fertilizer, pesticide abuse make the soil organism reduce year by year, soil fertility level descends, thereby makes ecological environment of soil lose balance.Particularly in the cash crop area, vegetable growing is regional, and industrialized agriculture is regional.Lost at these ecological environment of soil balance place plantation crop with regard to be easy to occur growing way poor, yield poorly and the problem of disease resistance insect pest ability.Therefore, cause the usage quantity of agricultural chemicals and these chemical of weedicide constantly to increase, made again the quality of crop descend, the problems such as soil pollution is serious, soil acidification, the hardening soil, heavy metals exceeding standard.As seen, this is a pernicious circulation.Above-mentioned problem finally can cause headachy soil-borne disease big area to occur.
Soil-borne disease refers to live in germ main harm plant root or the stem in the residual body of diseased plant in pathogenic bacteria in soil or soil, infect vascular bundle, developed to stem apex by root, pathogenic bacteria breeds in vascular bundle, block it and carry nutritive substance, cause plant withered, dead, rotten etc., bring havoc to agriculture production.
The appearance of soil-borne disease has not only affected the yield and quality of crop, and owing to usually needing agricultural chemicals or microbiotic that the crop state of an illness is controlled and treated, also food, grain security have been arrived in serious threat.According to statistics, the average amount of application of China's agrochemical unit surface reaches 434.3 kg/ha at present.And the chemical fertilizer application upper safety limit of generally acknowledging in the world is 225 kg/ha, and the average amount of application of agrochemical unit surface of China is 1.93 times of upper safety limit.
For avoiding crop to be subject to soil-borne disease, also there is the phenomenon of abuse in the use of agricultural chemicals.Up to the present, the chemical pesticide annual production is nearly 2,000,000 tons in the world, approximately has 1000 kinds of artificial synthetic compounds to be used as the agricultural chemicals such as sterilant, sterilant, algicide, insecticide and defoliant.The average usage quantity of China's agricultural chemicals is 13.4 kg/ha at present, has 60 ~ 70% can remain in soil after the applications of pesticide.And indiscriminate use of pesticide is also the important factor that causes soil and agricultural-food harm.A large amount of uses of agricultural chemicals have caused serious Pesticides Residues, become the serious threat to HUMAN HEALTH.Long-term pesticide residue are accumulated gradually at human body, finally cause body physiological function disorderly, even cause chronic poisoning and teratogenesis, carcinogenic, mutagenesis.Serious threat is to multiplying and living of national health and descendants.
Antibiotic extensive application has also caused impact to soil safety to a certain extent.Calculate according to the expert, annual about 210,000 tons of the microbiotic raw material of producing of China wherein has 9.7 ten thousand tons of microbiotic to be used for livestock breeding industry, accounts for 46.1% of gross annual output amount.These microbiotic also can enter the edaphophyte system by feces of livestock and poultry becomes another source of pollution.
In sum, a large amount of uses of chemical fertilizer are the basic reasons that causes soil-borne disease serious, therefore, are necessary existing chemical fertilizer is improved.
Summary of the invention
The object of the present invention is to provide bulk blended fertilizer a kind of comprehensive nutrition, multi-functional, ecological, environmental protective, unreasonablely use soil pollution, soil-borne disease that chemical fertilizer causes degradation problem under serious, agricultural product quality occurs to solve in prior art due to a large amount of.
For achieving the above object, the present invention adopts following technical scheme:
A kind of bulk blended fertilizer of preventing and treating soil-borne disease, the raw material of described bulk blended fertilizer comprise nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, boron fertilizer, zinc fertilizer, molydbenum fertilizer, manganese fertilizer, copper fertilizer and wilkinite;
Described nitrogenous fertilizer comprises urea and calcium cyanamide; Described phosphate fertilizer comprises monoammonium phosphate and fused(calcium magnesium)phosphate; Described potash fertilizer is Repone K, saltpetre, vitriolate of tartar or solubility in citric acid potassium; Described boron fertilizer is borax; Described molydbenum fertilizer is ammonium molybdate or Sodium orthomolybdate; Described zinc fertilizer is zinc sulfate; Described manganese fertilizer is manganous sulfate or Manganous chloride tetrahydrate; Described copper fertilizer is copper sulfate.
Bulk blended fertilizer provided by the invention comprises macroelement nitrogen, phosphorus, potassium, moderate-element calcium, magnesium, sulphur, and micro-chlorine, manganese, zinc, boron, copper and molybdenum also comprise useful elemental silicon, and comprehensive nutrition comprises the required whole nutrition of plant growth.After using bulk blended fertilizer of the present invention, the resistance against diseases of crop obviously improves, thereby plays the preventive and therapeutic effect to soil-borne disease, reaches few use and does not even use agricultural chemicals or antibiotic effect, makes product reach nuisanceless standard; And the raising product quality is recovered the intrinsic local flavor of product.
Element in the raw material of bulk blended fertilizer of the present invention is plant and can absorbs, so this bulk blended fertilizer use range is wide, environment friendly and pollution-free; Use and can not pollute soil afterwards, can well keep the stable of ecotope, safety, environmental protection are the desirable fertilizer of producing pollution-free food, green food.
Preferably, the parts by weight of described each raw material of bulk blended fertilizer are:
