Description
Technical field
The invention provides a kind of new purposes and using method thereof of nuisanceless gas.
Background technology
China market gardening area under cultivation have only 13.9 ten thousand hectares in nineteen ninety, during by 1999 sharp increase 11 times, reach 168.4 ten thousand hectares.
Before nineteen ninety, the market gardening of China mainly is a tunnel type cultivation booth, but after this 10 in the period of, the greenhouse Area Growth 15 times, the plastic tunnel Area Growth 13 times, during by 1999, both totals have arrived 60% of whole market gardening areas.
In 10 years before 1999, the area sharp increase in novel daylight type greenhouse 45 times, the outside in this greenhouse utilizes the heat insulation type material to cover, and need not to heat and just can carry out overwintering cultivation.Before nineteen ninety, most daylight types greenhouse is used for culturing vegetable, belongs to the very thin simple type greenhouse of outer wall, but by 1999, novel solar greenhouse accounted for 60% of whole greenhouses area.
Its reason is that novel solar greenhouse need not to heat, from year June in autumn to the second, the very high crops of income such as cultivated cucumber, tomato, green pepper incessantly.
The market gardening of China has very big potentiality.The area of daylight type greenhouse and plastic tunnel also will significantly increase.Use the SOUTHERN CHINA and the northern summer of agricultural chemicals in a large number at high temperature, the way of using fly net and biopesticide etc. to hang down the agricultural chemicals cultivation is popularized rapidly.
The contribution of chemical pesticide is universally acknowledged.Owing to use agricultural chemicals effectively to control disease, worm, the crop smothering of crops, the whole world retrieve every year with a toll of 30%-40%.There are 838 kinds of insects (evil mite) in China according to statistics, and the SOUTHERN CHINA and the northern summer of using agricultural chemicals at high temperature in a large number, insect pest is lost in more than 90% for vegetable growing.
Yet, using chemical pesticide, medicament residue is serious, and harm is big, has caused relevant department and consumer's great attention; And, use agricultural chemicals, the amount of labour is big, the expense costliness, increased greatly plant, planting cost, benefit is slight.
Summary of the invention
Technical problem to be solved by this invention is: a kind of new purposes of nuisanceless gas is provided, nuisanceless gas is used as the field insecticide, and simple using method is provided simultaneously.
The present invention proposes nuisanceless gas as field desinsection, bactericide.The nuisanceless gas of indication of the present invention is one or both the mist in carbonic acid gas, the nitrogen, or based on its gas, may contain assorted gas such as hydrogen, methane, carbon monoxide, alcohols, organic acid, and in some cases, ozone also can.With carbonic acid gas is best, stable performance, and again than great, the operation of being convenient to fill nuisanceless gas and discharging air.
Using method is that use zone is airtight, to wherein charging into nuisanceless gas, makes in the closed area near anaerobic, breaks off the breathing of insect, aerobic germ, weeds, makes insect, germ, weeds lose the condition of existence and death.
When filling nuisanceless gas to the closed area, the air in the closed area is discharged from outlet, be convenient to realize anaerobic state.
In order to guarantee the survival of crop seeds, the gas disinsection method must carry out before plantation.
Among the present invention:
Gas is high concentration gas, and greater than 90%, effect is obvious as gas concentration lwevel; The concentration of nitrogen is advisable greater than 98%, still, because of the cost height, is unfavorable for applying; Both mists can obtain under some conditions at an easy rate, and are therefore also easy to utilize, and the composition of its gaseous mixture is controlled to be carbon dioxide 30～40%, nitrogen 60～70%.
After nuisanceless gas is filled in the closed area, preferably keep a period of time, to guarantee to obtain effectiveness preferably.Usually, the retention time was advisable with 2 hours～10 days, was preferably 5～7 days, and the time is too short, is unfavorable for guaranteeing treatment effect; Time is oversize, is a kind of waste, increases cost, there is no need.
Utilizing nuisanceless gas to replace traditional agricultural chemicals is a problem that develops green agriculture now as insecticide.In airtight daylight type greenhouse and plastic tunnel, pass through to add certain density nuisanceless gas at certain hour, under the condition that guarantees the vegetables psychological need, make insect, germ death by suffocation, thereby stopped to have of the residual harm of the chemical pesticide of public hazards the human body generation.The soil increase gas permeability of digging is beneficial to desinsection, sterilization before using, and uses back emptying displacement several days, makes soil, air satisfy the vegetables psychological need.
Each 10 yuan to 15 yuan for the every canopy mu of the expenses for prevention and control of damage by disease and insect of peasants, per 5 days of high temperature season is with an agricultural chemicals, about 500 yuan of full year costs.And in protection ground cultivation so long as enclosed system all can use CO throughout the year
2Agricultural chemicals can make full use of the dull season that carbon-dioxide gasfertilizer uses like this, as spring, summer, kind season, makes the annual running of the fertile engineering of gas.The pollution-free vegetable price can be doubled for agricultural, strives for maximum return.
In the crop rotation interval of crop, utilize its closed environment, pour the anaerobic carbon dioxide to its inside, near anaerobic, the content of oxygen is less than 2% in making between the chamber, make all animals and plants lose survival environment, fermentation becomes fertilizer within a certain period of time, harmful to economic crops like this weeds and seed thereof, and the worm's ovum in insect and the soil, germ are all with death, saved the use of the agricultural chemicals of a large amount of desinsection grass, stopped therefore and the public hazards that produce.If in conjunction with the decomposition that utilizes the sterilizing of ozone gas and ozone saturated aqueous solution to agricultural chemicals etc., will make closed environment reach nuisanceless standard at short notice again, save the time of transforming nuisanceless environment traditionally with triennium.Reduce entering of insect by being used fly net after the environmental reconstruction, can make in this protection ground and produce non-harmful victual.
In more than describing, what the composition of gas and content were represented is the volume composition and the content of butt, as follows.
When utilizing nuisanceless gas desinsection; in order to reduce its consumption, environment and personnel are caused damage preventing, can utilize non-ventilated membrane restriceted envelope; if such as the protection ground in only to ground desinsection, sterilization; can shroud with mulch film, behind the row's for the treatment of air will around airtight, airtight nuisanceless gas in soil, permeate kill off the insect pests, the worm's ovum in germ and the soil etc.; several hectosteres of ampoule; price also is an acceptable, for carbon dioxide, and only several yuans.If to ground and desinsection, the sterilization together of body of wall canopy film in the protection ground, can take main space in the canopy is full of with non-ventilative air bag available air filling in the air bag, remaining space CO
2Pour from the bottom, air is discharged from the top, air drains the rear enclosed top eye of wind, is guaranteeing CO
2Use CO under the condition of high concentration less as far as possible
2, several hectosteres of ampoule, price also are acceptables.Also can carry out large tracts of land CO at calm spell for open-air economic crops soil by the large tracts of land mulch film
2Desinsection, sterilization reduce environmental disruption, benefit the whole mankind.Be beneficial to the greenhouse effect of carbon dioxide, sunlight sees through film and carbonic acid gas gas-bearing formation, and directive ground is formed heat zone by carbon dioxide absorption during the longwave optical line reflection in the soil surface layer, and desinsection, bactericidal effect are better, and high temperature virus killing effect is also better.
Points for attention: CO
2Though gas is non-toxic gas, it reaches finite concentration the people is harmful to, and allows maximum concentration 5% in the air, and in 10% environment, the people will suffocate slow-witted a few minutes, so must note its safety in the operation.Store CO easily for low-lying place
2The place of gas must not enter before not ventilating.When consumption is big, need special messenger's operation.
Other nuisanceless gas such as nitrogen is basic identical as the principle and the carbon dioxide of field desinsection, sterilization.
Nuisanceless gas such as carbonic acid gas, nitrogen has isolated effect of breathing, and therefore also is used for fresh-keeping, refrigeration.
The source of the gas of nuisanceless gas can be produced with industrial method, in order to reduce application cost, carbon dioxide and nitrogen can adopt cheap industrial by-product gas, natural mine gas etc., as the carbon propylhomoserin is separated, hydrolysis produces high concentration carbon dioxide gas, ammonia factory and device for producing hydrogen produce greater than 95～99% the carbon dioxide that produces in 98% carbon dioxide, the fermentation process, carbon dioxide gas body burden in the natural mine gas more than 90%, lime production exhaust gas discharged: carbon dioxide 30～40%, nitrogen 60～70% or the like.
The new purposes of nuisanceless gas provided by the invention as field desinsection, bactericide, can be in large-scale application nuisanceless gas, replace agricultural chemicals, avoided the residual harm of agricultural chemicals, fundamentally really realized green planting, saved agricultural chemicals expense usefulness again, reduced to use the big amount of labour of agricultural chemicals greatly, reduced plant, planting cost, because of green plants, can also increase the planting technology added value greatly, improve the plant price, benefit is obvious, has broad application prospects.
