Description
Technical field
The utility model relates to and a kind of soil is carried out to the mechanism that the root nematode is killed in the steam heat injection, belongs to soil heat injection technical field.
Background technology
When vegetable basket is enriched constantly, " residue of pesticide " problem is also a shade of can't get rid of.In the present circumstance, solve " residue of pesticide " problem effective method a lot, still, these methods all can increase considerably Vegetables cost, and then impact is sold.
" residue of pesticide " of vegetables, can be divided into two kinds of situations substantially, and the one, agricultural chemicals is sprayed directly on the residue of pesticide that cause on vegetables, and the 2nd, vegetable plant directly absorbs agricultural chemicals and the residue of pesticide that cause from the soil that contains residue of pesticide.The first situation easily causes everybody attention, as long as and take some simple methods just can to alleviate or eliminate.
The agricultural chemicals remained in soil can enter in plant corpus by the root system of plant.Persticide residue in different plant bodies depends on their absorbing capacities to agricultural chemicals.After agricultural chemicals is absorbed, in plant corpus, the order of abundance is: root > stem > leaf > fruit.This situation just is difficult to cause everybody attention, and this residue of pesticide can be penetrated into a cell of vegetable plant, and the consumer is difficult to remove this residue of pesticide, and this situation is the principal mode that " poisonous vegetables " produce.
Agricultural chemicals is double-edged sword, in pest control treatment weeding and raising crop yield while, also can exceed standard because the agriculture that pesticide abuse causes is residual.Only control the factors such as types of medicines, insecticide spraying time, Drug level, safety interval well, residue of pesticide will reduce.Residual in soil of agricultural chemicals is the maximum root that agricultural environment is polluted.Root knot nematode disease is to occur in the multiple Vegetables such as one of disease comparatively serious on vegetables, main harm cucumber, balsam pear, tomato, eggplant, Kidney bean, celery, spinach, carrot.And along with the adjustment of crop mix, the rapid expansion of vegetable protecting field area under cultivation, root-knot nematode is pathogenetic increases the weight of year by year, and production loss reaches 30%～50%, ruins the seedling event of heavily planting and often occurs.Root-knot nematode harm has simultaneously increased the weight of again the generation of the native transmissibility fungal disease such as fusarium wilt, root rot and parts of fine fungus diseases, has become the large obstacle that current vegetables produce.Root-knot nematode lives in underground, and its mechanics be difficult to is grasped at the plantation family, thereby is difficult to find the best method of preventing and treating, and the fast and medication of its spread speed simultaneously ought be all the reason that causes the root-knot nematode refractory.
Root-knot nematode is mainly invaded the root of vegetables with second instar larvae, make root form root nodule, especially killed serious with lateral root and fibrous root, form atypic large tumour, root system overstriking, air spots when serious on root knot top, and root rots gradually, plant is withered because of lack of water.After being infected, morbidity the lighter overground part Symptoms is not obvious, and the severe one acrial part also has obvious ANOMALOUS VARIATIONS, disease plant depauperation, poor growth.When serious, plant wither, like lack of water, starts the only whole strain of high temperature at noon and wilts, and can also recover normal sooner or later, and plant wither can not recover again afterwards, finally caused withered death.Control to root-knot nematode should be implemented and take cultural control as main mainly to put prevention first, and chemical control is the auxiliary method of preventing and treating, and eliminates the worm source, alleviates harm.
In recent years, due to the continuous expansion of continuous cropping booth vegetable area, and medication science not, causing nematode developmenting spread speed, resistance strengthens.The crop death rate constantly increases, thereby causes the crop Severe Reduction, and quality reduces, and has had a strong impact on crops production.According to our investigation, take cucumber as example, root knot nematode disease generation canopy chamber death rate is generally 20～50%, and the most serious canopy of ruining has no harvest.
Especially at the green house planting vegetable, because the continuous cropping phenomenon is outstanding and for successive years after planting vegetable, nematode population in soil sharply increases, root knot nematode disease occurs serious, have a strong impact on yield of vegetables, simultaneously, the breeding that the warm humid climate condition of booth is damage by disease and insect provides suitable condition, and damage by disease and insect occurs frequent.In production process, in order to improve the output of crops, the agricultural chemicals of having to use in a large number, after agricultural chemicals is used, nearly 80% ~ 90% residue of pesticide are in soil.
In the face of multiple disease pest and weed, keep output, using agricultural chemicals to prevent and kill off is the most convenient feasible way.Along with the enhancing of disease pest and weed resistance, the plantation family increases types of medicines thereupon, improves pesticide concentration, shortens the medication interval phase, so operation, and the residual risk of exceeding criterion of agricultural chemicals will strengthen; In order to pursue higher output, chemical fertilizer and hormone kind are more many with using, and use more assorted and more assorted, and Use out of range chemical fertilizer and hormone phenomenon are seen everywhere now, even more serious in fruits and vegetables growing area situation, and the thing followed is exactly that content of beary metal exceeds standard, hormone-content exceeds standard.
Simultaneously, on market, agricultural product are adulterated, mix the genuine with the fictitious, had a strong impact on market comsupton, the high quality agricultural products dull sale, be difficult to allow those really realize with the matter price in strict accordance with agricultural product nuisanceless or that the pollution-free food production rules are produced, allow the plantation family really enjoy the high-quality excess earnings of bringing.
The aggregate measures of preventing and treating root knot nematode disease are more, but select efficient medicament, are the first-selected means of this disease of control, prompt drop nematode density, emergent control caused harm and had unique advantage, but just have unavoidably negative effect as killing the nematode agricultural chemicals.At present, the plantation householder will adopt methyl bromide fumigation and agricultural chemicals to fill with these two kinds of method control root knot nematode diseases of root.A large amount of highly toxic pesticide that use are filled with root, have not only destroyed crop root, but also have destroyed root system beneficial microorganism living environment in soil, break the soil balance, cause vicious circle, cause nematode more and more serious.
Celfume has severe toxicity, is a kind of strong never poison, can cause direct damage to people's skin, lung, kidney and liver.The symptoms such as heart failure, shock can appear in severe poisoning, and indivedual poisoners also there will be and lose the sight of both eyes.Simultaneously, it has strong fumigation action, can kill various pests efficient, wide spectrum.It has very strong penetration capacity to soil, and can be penetrated in the organism that rots to decompose, thereby reach the purpose of deinsectization, diseases prevention, weeding, be a kind of soil fumigant that welcome by the peasant.
In large field, after soil-fumigating, residual agricultural chemicals can volatilize rapidly, in the short time, can sow or field planting., in airtight greenhouse vegetable booth, it is difficult to volatilization, and, plantation family often excessive use again, uninterruptedly plantation, cause residue of pesticide in soil, and then be absorbed by plants again.
Long-term a large amount of use of agricultural chemicals, residual accumulation, cause soil pollution.When the soil planting crop by pesticide pollution, crops absorb the agricultural chemicals in soil, and agricultural chemicals accumulates in agricultural product, has reduced the quality of agricultural product.Long-term edible food of being cultivated by pesticide contaminated soil, will threaten health.
Bread is the staff of life, and food is with An Weixian, and along with the pay attention to day by day of consumer to food security, traditional cropping pattern way to manage has run into unprecedented challenge." agriculture is residual " problem of repeatedly producing has been pushed " high poison ", " high residue ", " agricultural chemicals " to the teeth of the storm.
Root-knot nematode is distributed in 0～30 centimetre of soil more, particularly in 3～9 centimetres of soil, nematode population is maximum, often with ovum or 2 instar larvaes, with plant residue, be retained in soil or in muck, survive the winter or when next year, environment was suitable with 2 instar larvaes from tender intrusion, breeding is caused harm.In greenhouse by solar heat, can cause harm all the year round.Nematode can be by band worm soil or seedling and irrigation water propagation.25～30 ℃ of soil temperatures, soil moisture is that under 40%～70% condition, the nematode breeding is very fast, easily accumulation in a large number in soil, stop action below 10 ℃, death in 10 minutes in the time of 55 ℃.The worm's ovum buried depth of main soil insect is distributed in substantially in 20 centimetres, adult and the worm's ovum that while more than soil temperature reaches 50 degree, also continuing 15 minutes, can effectively kill various soil insects.
