Description
Technical field
The present invention relates to a kind of method of device and disinfection soil thereof of ozonization soil.
Background technology
Diseases and pests of agronomic crop is one of main natural calamity of facing of the mankind, and it has, and kind is many, influence is big and break out the characteristics of causing disaster often.Annual in the world due to illness insect pest causes the loss of fruit tree, vegetables to be about 15～20%.China is since the fifties in last century, the generation area of crops main diseases insect pest constantly increases, particularly since the phase at the beginning of the seventies in last century, damage by disease and insect generation area and occurrence frequency increase year by year, become the main restricting factor of China's development an agriculture featuring high yields, fine quality and high efficiency.
At present chemical pesticide is mainly adopted in the control of pest disaster.Because long-term a large amount of agricultural chemicals that uses, air, water source, soil and food are polluted, and poisonous substance is accumulated in livestock and the human body and causes poisoning, causes the pesticide hazards problem.Show according to relevant survey data: have people's liver function of 10% bad in the urban human, the vegetables that have remains of pesticide are relevant with eating.Remains of pesticide also can endanger nervous system and other organs of people, brings out sudden change, causes cancer and chronic poisoning etc.Even more serious is that because the stimulation of agricultural chemicals, the pesticide resistance of insect is more and more stronger, because pesticide resistance and the agricultural chemicals of insect kill a large amount of beneficial organisms simultaneously, having caused insect rampant more, formed vicious circle, is " the suicide agricultural " of destroying natural ecological environment.After China joined WTO, agricultural production also is faced with technical challenges such as global green barrier, and the development pollution-less agriculture has become the development trend of the future of agriculture.In recent years, along with the raising of expanding economy and living standards of the people, China's industrialized agriculture is in the opportune moment that unprecedentedly develops rapidly, and indoor crop disease and insect is serious day by day but the thing followed is a canopy; And, in booth, the greenhouse behind the applying pesticides degradation of pesticide speed generally slower.
Soil is the main media that damage by disease and insect is propagated, and also is the main place of damage by disease and insect breeding.Many germs, worm's ovum and insect all survive in soil or survive the winter, and wherein also often have weed seed.Indoor or fixedly during the farming of field piece continuous cropping at canopy, can cause that the pest amount increases severely in the soil, damage by disease and insect increases the weight of year after year, makes that crop yield such as vegetables falls sharply, quality descends.For example a large amount of accumulation of soil-borne diseases such as strawberry fusarium wilt, root rot, verticillium wilt, eqpidemic disease, pathogen will be produced to strawberry and be brought massive losses.Tomato is one of main vegetable species of China's protection ground cultivation.Because continuous cropping for many years causes soil-borne diseases such as fusarium wilt, root knot nematode disease more and more serious, seriously restricted the development that protection ground vegetables produce.The general underproduction 20%～40%, the underproduction reaches more than 60% even total crop failure when serious.Change new soil as if soil in the canopy is shifted out, waste time and energy, also will follow the track of the overturned cart after a period of time.Before crop-planting canopy chamber disinfecting soil being handled is a kind of method of the active and effective insect pests crop smothering that is widely adopted, canopy chamber disinfecting soil is handled the main stifling method of chemical reagent that adopts both at home and abroad, stifling or the physical methods such as baked wheaten cake, water logging of a small amount of employing high-temperature steam are arranged
Soil disinfection is the effective way that addresses this problem.Seedbeds such as vegetables, flowers, treelet are all answered thorough disinfection with soil, potted flower before with uses such as soil, open-air ground, garden, to prevent the generation of disease pest and weed.For a long time, the most frequently used soil disinfectant of people is a methyl bromide, is high malicious insecticide (fumigant), soil is passed pest is efficient, wide spectrum, has desinsection, nematicide, sterilization, kills spider, weeding, multiple efficacies such as kill mouse.Methyl bromide is strong and rapidly to the soil penetration power, and plant parasitic nematodes, perennial weed and most of annual weed seed, cutworm and other larva of all vegetative stages of all kinds, moth aunt, various boa wax, ant, the autochthonal insect of beetle, pure sick, the black corruption of root, the balck shank etc. of falling are had good killing effect.The Celfume soil disinfection method that is widely adopted not only has production-increasing function to this season crop, and succession crop is still had certain production-increasing function.And can obviously improve the yield and quality.After the Celfume soil disinfection, the soil disinfection of multiple spot test Celfume all has production-increasing function to cucumber, and amount of increase in production is 7%～34%, and can obviously improve cucumber Vc content.But, in the methyl bromide use of various uses, there is 32～95% methyl bromide to be discharged in the atmosphere and goes because Celfume is a kind of material that damages the ozone layer.According to " Montreal Protocol Copenhagen amendment ", various countries stopped to produce and using Celfume gradually after 2005, will eliminate in 2015 in developing country.Simultaneously, because Celfume has high toxicity, improper use easily causes the person poultry poisoning, uses also inconvenient.Seeking and substituting the methyl bromide new technology is the hot issue that many scientific domain scientific workers such as extremely national governments and global plant protection, environmental protection etc. pay close attention to.External research is in this respect carried out relatively early, and is also more deep, and China has colleges and universities such as China Agricultural University to carry out adopting other chemical reagent to substitute the research of Celfume at present.At the present situation that agricultural disease Chinese caterpillar fungus disaster is becoming increasingly rampant, chemical pesticide harm is serious day by day, scientists is explored nuisanceless method, and to administer the interest of agriculture disease pest and weed strong day by day.Existing plant disease pest and weed is prevented and treated in the improvement of method cost great amount of manpower and material resources after the disease pest and weed large tracts of land is broken out, expend after the lot of manpower and material resources, still can cause a large amount of losses, and can not root out root, can only control to a certain extent, also can recur during conditions being possessed, a large amount of agricultural chemicals also causes human and the far-reaching lasting harm of natural environment.
