Description
Technical field
The utility model relates to a kind of soil sundry separating device that purifies soil for reclaiming mulch film, belongs to plant equipment field.
Background technology
Film-mulching cultivation technique is introduced into China in the seventies in last century.Mulch film is a kind of plastic film, spreads it, can heat, moisturizing, soil conservation, fertilizer conservation, insect protected etc.Especially in arid area, there is significant effect of increasing production, become a core technology of China's dry farming.Over nearly two, 30 years, China's plastic mulching area and usage amount occupy the first in the world always, according to < < Chinese agriculture statistics > >, calculate, within 2010, National Agricultural plastic film annual turnover reaches 118.4 ten thousand tons, and area coverage reaches 3.5 hundred million mu; Within 2011, national plastic tunnel plastic film annual turnover is approximately 1,000,000 tons, and area coverage reaches more than 5,440 ten thousand mu.
Eighties of last century is since the eighties, and the west areas such as Xinjiang start on cotton, corn, growing vegetables, to promote the use of film-mulching technique on a large scale, and crop yield is increased substantially.Enter after 20th century modern agriculture that " under-film drip irrigation " technology of take is representative, the growth record that continues refreshing various crop yields.Collection plastic film mulch, sow, tillage method that fertilising, irrigate band are laid in one, not only saved precious water resource, also make a large amount of farmlands inferior, no longer cultivated farmland become high-yield field, become " magic weapon " of various places, the Northwest increasing peasant income.
But a lot of people are perhaps unexpected, the mulch film that can increase production, also can bring harm.Along with mulch film usage amount increases year by year, the problem that overlay film brings also comes one after another.
The cotton planting district in Xinjiang will be counted in the most serious place of China's Plastic-film pollution at present.The a research report demonstration of announcing for 2008, in cotton field, Xinjiang region, 265.3 kilograms of the average per hectares of mulch film residual quantity, and along with the overlay film time limit is longer, pollute more serious.In Xinjiang, the continuous cotton field of overlay film 10 years, 15 years and 20 years, mulch film residual quantity is respectively 262 kilograms/hectare, 350 kilograms/hectare, 430 kilograms/hectare, and severe contamination field agricultural mulching residual quantity is up to 597 kilograms/hectare.Does is what concept this? generally, if spread mulch film to 1 hectare of soil, usage amount is about 60 kilograms, and the mulch film residual quantity of 597 kilograms is equivalent to store 10 layers of mulch film in ground.
These mulch films of being made by polyethylene itself cannot be degraded, if left, it is a large amount of in the ground residual, and after a lot of years, these farmlands just likely cannot regrowth crop, and a large amount of mulch films is residual, will affect China's ability of agricultural sustainable development.And more alarming, except the impact on agriculture, in soil, wrap up in and containing a large amount of white pollutions, can or can not work the mischief to environment, water and soil, produce far-reaching influence more? research work at present does not also relate to.
The research report demonstration providing according to autonomous region academy of agricultural sciences, Xinjiang, crop yield is on a declining curve with the increase of residual-film amount.Take cotton as example, and when in soil, residual-film amount reaches 3.5 kilograms every mu, at least the underproduction 15%.Some agricultural experts point out, in recent years, the technology such as universal fertilization compositions based on earth measurement, high-new water saving are all widelyd popularize in various places, Xinjiang, but the effect of increasing production of crop is offset by residual film substantially.
If be just on fragment after also having planting seed, just influential to its germination, the phenomenon of being short of seedling may be very serious, causes the underproduction.Can have influence on the migration of moisture and nutrient in addition, influential to the growth of crops root system.According to surveying and determination, the with serious pollution soil of residual film can make wheat yield decline 2%～3%, corn yield 10% left and right that declines, and output of cotton declines 10%～23%.
Farmland residual mulching film can also make soil environment worsen, and soil moisture content declines, and weakens drought-resistant ability, causes secondary salinization, hardens and fertility decline, affects crop growth, causes the underproduction.According to surveying and determination, broadcast the seed on residual film, rotten kind of rate can reach 6.92%, and rotten bud rate reaches 5.17%, and output reduction reaches 12% left and right.In addition, it also affects agricultural machinery working quality.
Remove at present mulch film and mainly by machinery, hug and take off, manually pick up, in many places, mulch film is weathered into nail cover size, cannot pick up at all.Because mulch film is mainly that thickness is in 0.008mm and following what is called " ultra-thin mulch film ".This mulch film poor ductility, aging fast, what have even will be damaged less than results season.Strengthened ground membrane removal difficulty.
