Description

One grow wheat Chinese herbal medicine agriculture chemicals and production method

Technical field

The present invention relates to a kind of green agriculture chemicals of noresidue that can prevent and treat the wheat crop pests, a kind of specifically is the environment friendly agricultural that raw material is made with the Chinese herbal medicine, it does not contain the residuals harmful to animal, be a kind of non-harmful environmental protection agricultural chemicals, the invention still further relates to the method for manufacturing of this environment friendly agricultural.

Background technology

At present, known agricultural year must spray a large amount of chemical insecticides to crops.These have the agricultural chemicals of Hazardous, have caused the serious residue of pesticide that exceed standard in grain and natural environment, and it is encroaching on people's human body, affect the healthy of the mankind.Current, it has been recognized that the harmfulness of its chemical pesticide, it has changed soil, makes alkalization of soils; Polluted environment, caused serious life too uneven, caused a lot of small animals and birds extinction, its residual harmful substance is also having a strong impact on the species procreation of the human healthy and boundless universe.As everyone knows, agricultural chemicals is the important assurance of guaranteeing agricultural foison, but the chemical pesticide pollution level is destroyed the ecological balance, contains high toxicity in agricultural byproducts, high residue causes direct threat to the human life, has also formed global public hazards.

For example: the use of chemical pesticide makes the barren and alkalization of soils in soil; Make that to contain a large amount of harmful chemical pesticides in the grain food residual; The meat of class animal contains and deposits carcinogen in making; Make transmutation of species; Make a lot of animal extinctions; All misleads of these chemical pesticides, all strong proof the extent of injury of chemical public hazards agricultural chemicals to the ecological balance, animal survival, human life and large natural environment, its extent of injury is increasing, also makes human cancer morbidity come height more.Chemical pesticide has hundreds of kinds in the whole world, the number nearly 4,000,000 more than that the annual whole world causes death and dies because of pesticide poisoning, according to statistics, 2/10ths of China's arable area has been polluted by the chemical pesticide degree of depth, there are nearly 1,000,000,000 populations all to eat the food that these contain the high residue chemical pesticide every day, directly endangering the healthy of people, countries in the world government all seek a kind of nuisanceless, avirulence is residual and the novel agrochemical of secondary pollution.

At present, all there is following point in the development of public nuisance-free agricultural chemicals both at home and abroad:

1, existing public nuisance-free agricultural chemicals result of use is poor, is because it does not form the special-purpose agricultural chemicals that the crops classification is used.

Though 2, classification such as biopesticide white muscardine fungi, BT is used, because of being subjected to region and weather condition effect, and the effect of large area control insect pest is all undesirable.

Though 3, plant pesticide has fine insecticidal activity.But because of prescription not reason such as science, folk prescription insect is developed immunity to drugs in a short time and does not reach the expection insecticidal effect because it does not form a kind of plant pesticide of special-purpose control wheat damage by disease and insect.Some plant pesticide can be controlled pest at present, can control forestry pest again, this is unscientific, because agricultural and forestry pest are the insects of two big class life habits, besides the life habit of crop pests is also all inequality, and the insect of paddy rice and wheat is exactly two kinds of life habits, so medication cannot treat different things as the same, must have science, branch seasonality and specific aim and use, otherwise will produce many-sided ill effect.More than many shortcomings, demand urgently improving.
