Waste plastics mulch film is while continuous processing system.
Background technology
1st, agricultural wastes --- stalk and plastic film
Past domestic plastic sheeting large area agriculturally is used, and causes following harm to China's agricultural：
（1）Destroy soil texture
Residual film needs to decompose for 200 years ~ 400 years in farmland, and residual film for many years is not reclaimed, mixed in together with soil,
Hardening layer that is airtight, not returning moisture in the soil is formed in 30 centimetres of the top layer soil of arable land, the reproducibility of soil is restricted, to soil thing
Rationality matter, soil chemistry reaction, the particularly destruction of soil granular structure decline soil productivity, and crop yield is reduced,
Natural environment and farmers' income are all caused and had a strong impact on.
（2）It is unfavorable for crop normal growth and development
The plastic sheeting remained in soil is unfavorable for the motion of soil moisture and the exchange of soil gas, due to plastics relic
Barrier, soil water movement is obstructed, porosity, permeability reduction, is unfavorable for the circulation and exchange of soil air, can make soil
Middle carbon dioxide content is too high, is unfavorable for crop normal growth and development, and residual film can cause germination difficult, root system production by
Resistance, seed is broadcast causes the rotten bud of rotten kind in residual film, and rotten bud rate reaches 5.17%.And according to statistics, overlay film averagely makes Yield Increase In Cotton 16%,
And the overlay film cotton field residual film of 20 years can make the cotton underproduction 12%, volume increase part is almost offseted by residual film harm and mulch film cost.
（3）Influence the microbe survival in soil
Plastic sheeting is a very long process in the decomposition of soil, can decompose and volatilize many harmful substances, cause in soil
Microorganism growth retardation, makes the activity reduction of soil.
（4）Polluted underground water
Plastic sheeting with the addition of the harmful substance produced in many chemical substances, decomposable process in process of production can be to underground water
Impact, polluted underground water.
（5）Plastic sheeting in soil, which is dealt with improperly, can cause the secondary pollution of environment.
By taking Xinjiang as an example：According to the rough estimates of the Agriculture in Xinjiang Room by 2014, Xinjiang crop film-coating area is up to 4700
Ten thousand mu or so, account for crops and always broadcast more than the 70% of area, use mulch film total amount year up to 18.5 ten thousand tons, but whole district farmland is waste and oldly
Film recovery utilization rate is less than 10%.
Investigation result shows that the average every mu of residual mulching film amount in local farmland has reached 16.88 kilograms, and year is total using mulch film
Amount is up to 18.5 ten thousand tons.And in some small towns of Xinjiang region, mulch film residual quantity is even up to more than 40 kilograms, by annual every mu of plastic film mulch
4 kilograms of calculating, 10 layers of mulch film have been spread equivalent to farmland.
By " accumulation " of more than 30 years, the agricultural mulching for being once referred to as agricultural development " boost motor " had resulted in new sorrow
Suffer from, be to push soil aside to look for mulch film in the past, be to push mulch film aside to look for soil now.
