Description
The present invention relates to the manufacturing technology field of environment friendly agricultural.
At present, more than 200 of the pesticide species that China produces, wherein bigger basic kind is kind surplus in the of 10 only.In all kinds of agricultural chemicals output, insecticide accounts for 70% of gross yield, although weed killer herbicide development is very fast, only accounts for 16% of gross yield, and bactericide only accounts for 10%, and this and developed country's gap are bigger.In developed country's pesticide structure, general insecticide accounts for 30%, and weed killer herbicide accounts for 45%-48%, and bactericide accounts for 18%.In the insecticide of China, organophosphorous ester insecticides output will account for 70%, and in organophosphorus insecticide, a few high drugs kind output accounts for 70% again, three " 70% " of so-called unreasonable structure that Here it is.And 4 high drugs kinds listing among the PIC (prior informed consent program) account for 22.6% of agricultural chemicals gross yield.Account for 32.4% of insecticidal total output, organic phosphorous insecticide 46.5%.1999 also in rising trend.As acephatemet, 8000 tons of worldwide production less thaies, developed country not only is even China periphery developing country such as Indonesia, Vietnam, Cambodia, Sri Lanka etc. ban use of.These high drugs kinds have been used for many years, all have every year a large amount of people, animal poisonings to take place, and pesticide resistance is also increasing." PIC program " formulated in FAO (Food and Agriculture Organization of the United Nation) and United Nations Environment Programme (UNEP), lists 27 kinds of chemicals wherein in, and 22 kinds in agricultural chemicals comprises mass-produced these 4 the high malicious organophosphorus insecticides of China." PIC program " will rise to the international convention of acquire full legal force, and its enforcement will restrict the use of these kinds in the whole world, will have a strong impact on the outlet of China's agricultural chemicals.
Both at home and abroad aspect the preventing and treating of agricultural pest, all use the agricultural chemicals of chemosynthesis.These toxicity of pesticide are bigger, when killing damage by disease and insect, also absorbed by plant.When people eat these vegetables of using chemical synthetic pesticide, fruit and grain, can cause the incident of hurting sb.'s feelings of remains of pesticide.What have promptly is slight dose, does not cause harm to human health at that time, but often edible such grain, fruit, the vegetables of people in the course of time, have also brought potential harm to human beings'health, have also caused large-area pollution to ecotope simultaneously.So the expert of the parties concerned, scholar are appealing society always: advocate production " environment friendly agricultural ", reduce harm and the pollution of chemical synthetic pesticide to human and environment.
In recent years, along with improving constantly of living standards of the people, people were to the continuous enhancing of life and ecological protection consciousness, also arose at the historic moment in the planting experiment base of the nuisanceless grain in various places, vegetables.But as long as the growth of plant is arranged, damage by disease and insect is also just constantly followed.Because the long-term chemical pesticide that uses, various damage by disease and insect and bacterial virus have also had certain drug resistance.For this reason,, just have to use agricultural chemicals in a large number, even occurred getting more and more the phenomenon that increases the weight of year by year in order to guarantee the good harvest of agricultural.So the mankind expect to occur a kind of " environment friendly agricultural " and solve present this present situation always.Thereby prevent and protect for human life and health, society brings benefit to the mankind.
But development " environment friendly agricultural " is costly, the science and technology strength richness, and the lead time is long, and raw material disperse, and large-scale production is difficult to form.The most basic contradiction is: the pesticide cost of chemosynthesis is very low, and sterilizing rate, killing rate, extension rate are more cheap and efficient than the environment friendly agricultural of extracted form natural plant.So,, also be unable to do what one wants very much to do even each R﹠D institution wants to do.In addition, people's level of consumption and not strong to life protection consciousness, the green product that development person's fearness is put on market, the consumer acceptance leads not high.Simultaneously, be subjected to the restriction of conventional machining process, be difficult to produce the ideal green product.Even in the most flourishing U.S. and Japan, to from plant, extracting the research of environment friendly agricultural, also never have breakthrough progress, its sterilizing rate and killing rate are paced up and down about 30%-40% always.
Traditional Chinese medicine is the rarity of the Chinese nation.Its culture is long with the history source source and course.From the record that Zhang Zhongjing, Sun Simiao, Li Shizhen (1518-1593 A.D.) are shown, just can see the application prospect of Chinese herbal medicine, and can excavate more magnificent elite.
The researcher of our research institute on our basis of the medical older generation to the various argumentations of Chinese herbal medicine, is edified just, just carries out the research and the exploration of this respect from the end of the eighties, has spent a large amount of financial resources and manpower.By the tackling key problem of more than ten years, develop a cover scale finally, the new technology of " environment friendly agricultural " is produced in intensification; the adjustment of operation is on probation from the equipment design selection to technological process; possessed working condition, now formally put into production, produced " environment friendly agricultural " 500 tons per year.This equipment, technology cost are low, small investment, and instant effect, output is big.A factory that produces 500 tons per year needs 1,000,000 yuan of investment RMB.
The used raw material of the present invention is very abundant, and these raw material are discarded object at present entirely, as the roots of crops such as tobacco, cotton, sunflower, stem, leaf, branch, benevolence, shell, nuclear etc., the discarded object of Chinese herbal medicine processing enterprise; The forest farm, the branch of orchard and field crops, do, root, skin, benevolence, nuclear, shell etc.If utilize the present invention, these discarded objects will be fully used, and solve the pollution problem of ecotope simultaneously.
The primary raw material of producing " environment friendly agricultural " is: the root of crops such as tobacco, cotton, sunflower, stem, leaf, branch, benevolence, shell, nuclear etc., we can be rough estimate, at present, tobacco both domestic and external group, the tobacco leaf that annual product cigarette is used tons up to ten thousand, nearly hundred billion yuan of its output values, nearly 50,000,000,000 yuan of profits tax.Among the last 500 of the whole nation, nearly 20 families of tobacco enterprise, will eat up tens thousand of tons of tobacco leaves every year.The ratio of tobacco leaf and cigarette straw, cigarette muscle is 1: 1, and discarded object also will reach tens thousand of tons so.The still untapped at present one-tenth product of these discarded objects all abandons.Not only waste is greatly returned ecotope and has been caused great pollution.
According to the evidence that we study for many years, the discarded object of the cigarette straw of drying per ton, cigarette root and cigarette factory, with the manufacture method of our invention, its ratio defective product is 28%.The data that provides according to Dohanykutato Intezet of the Chinese Academy of Sciences proves that the discarded object of national cigarette straw, cigarette factory reaches few hundred thousand tonnes of, can produce 3100 tons of green products for 10,000 tons so.1550 tons elite part can be used for pharmaceutical industry, accounts for 50% of gross yield.Profit per ton is minimum presses 40,000 yuan of calculating, and gross profit is exactly 6,200 ten thousand yuan.Other remainder is used to make environment friendly agricultural, and profit per ton at least also gets 5000 yuan, and 1550 tons is exactly 7,750,000 yuan so.Above-mentioned two add up to 6,975 ten thousand yuan.This is 10,000 tons a profits tax total value, tobacco company of so national tens of family, and all development benefit is just considerable.In addition, cotton, sunflower etc. also is the main economic crops of China, and annual production is not less than tobacco.Root after crop such as cotton, sunflower is plucked, stem, branch, discarded part such as do, also can be used as our raw material of production " environment friendly agricultural " and made full use of.
