Technical field
The present invention relates to a kind of method of utilizing environment amenable material and physical characteristic thereof to come desinsection, weeding.
Background technology
China is the more serious country of agriculture pest disaster.It is reported, 1648 kinds of the main agriculture pests of China, wherein disease is 724 kinds, 838 kinds of worm (mite) evils, 64 kinds in weeds, 22 kinds of bandicoots.Chemical pesticide has been brought into play important function at the agriculture pest of control, protection agricultural production secure context.
Along with the increase year by year of applications of pesticide amount, the side effect of agricultural chemicals progressively is familiar with by people and is paid attention to.
One, the toxicity of agricultural chemicals; Agricultural chemicals also causes murder by poisoning to the natural enemy biology of the mankind, domestic animal, fowl, fish, honeybee, silkworm, birds, pest, the beneficial organisms such as beneficial microbe group in the soil in the agriculture pest of control.
Two, poisoning; The agricultural chemicals biologically active if crop growthing development is produced harmful effect, causes plant corpus to be injured, or the finally loss of agricultural output, quality, is exactly poisoning.Along with the fast development of farmland chemical weed control technology, the herbicide damage problem becomes increasingly conspicuous, and particularly wheatland uses the weed killer herbicide contain first, the grand composition of green phosphorus, and the poisoning of some of back stubble being made deposits yields should arouse attention.
Three, pesticide resistance; Pesticide resistance generally just can display under the condition of the same class agricultural chemicals of single use repeatedly, and pesticide resistance can heredity.Someone adds up, and the whole world is identified to have 504 kinds to develop immunity to drugs insect and mite class of some agricultural chemicals, and many plant species cause of disease plan biologies have produced resistance to some bactericide simultaneously, and some weeds is to also production resistance of some weed killer herbicide.Pesticide resistance becomes very important side effect in the agricultural chemicals use, has limited the development of agricultural chemicals.
Four, agricultural chemicals is to the pollution of agricultural product; The too short and direct pollution that causes dispenser excessive or interval dispenser phase apart from harvest time is wherein arranged, also have crop from pollute half to absorption, biological concentration and the food chain transfer function of agricultural chemicals and the indirect pollution that causes, embody a concentrated expression of that persticide residue exceeds standard in the agricultural product, person poultry poisoning's accident that persticide residue exceeds standard and causes in the vegetables, not only influence food security, but also influence the agricultural products in China export trade.
Five, agricultural chemicals is to the pollution of atmosphere; Mainly show spray insecticide, pesticide producing adds or the direct pollution that causes when storing and transporting.
Six, agricultural chemicals is to the pollution of soil; There is 25% ~ 50% medicament to fall into soil after the dispenser of farmland, float simultaneously and removing agricultural chemicals on crop also because of the flushing that drenches with rain falls into soil, form pollution, and then underground water is formed pollution soil in atmosphere neutralization, also comprise the unreasonable processing of pesticides packaging thing, the pollution that soil is caused.At present China suffers about 200,000,000 mu of the soil of pesticide pollution, and some soil pesticide concentration is up to 3,7 * 10
-6(weight ratio).
Seven, to the influence of agroecological environment; Agricultural chemicals also plays toxic action to the natural enemy biology in the control pest, may cause the minimizing and the elimination of responsive biological species, destroys the agricultural ecological balance, influences bio-diversity.
Because chemical pesticide uses the ill-effect that produces directly to threaten the food and the ecological safety of China.So the integrated control of harm such as phytopathy Chinese caterpillar fungus more and more obtains paying close attention to.
