Description
Technical field
The invention belongs to chemical fields, and in particular to a kind of PP Pipe Compound for preparing degradable mulch and use the PP Pipe Compound system
The method of standby degradable mulch.
Background technique
In China's agriculture field, the application of film-mulching technique to productivity significantly improve and the change of production method has
There is huge effect.Covering with ground sheeting has the function of that Meteorological effect, diseases prevention are pest-resistant and inhibits weeds etc., make crop yield 20%~
50%.But meanwhile covering with ground sheeting extensive use also brings a series of problems, uses and recycle unfavorable, mulch residual such as technology is general
Caused " white pollution " etc..
Mulch remains first is that can change soil texture.Residual film can reduce soil moisture content, weaken drought-resistant ability, cause secondary
Salination, causes soil hardening and fertility declines, and hinders soil to crop moisture, nutrient supply；Second is that will affect seed hair
Bud.Seed is wrapped up by residual film, being rotted because of poor air permeability, being withered because cannot get moisture, percentage of seedgermination is difficult to ensure, most
Crop yield is influenced eventually；Third is that agricultural machinery working quality and efficiency can be reduced.A large amount of presence of residual film can make machinery take place frequently in soil
Failure, off and on, quality and efficiency are all severely impacted mechanical work.These problems are to China agricultural sustainable development pole
It is unfavorable.
Whole life cycle design refers to causes a kind of plastics of degradation thin by the effect of microorganism in the natural environment
Film becomes one of the effective way for solving mulch residue problem at present due to its excellent degradability.Europe and Japan are
