Description
Technical field
The present invention relates to a kind of multifunctional agricultural film and preparation method thereof.
Background technology
Agricultural film plays very crucial effect in agriculture prodn, it has the effect of heat and moisture preserving, can improve the output of grain greatly.Yet can there be the problem of the following aspects in agricultural film in daily life:
1) agricultural film can receive the harm of mouse and insect unavoidably in the process of using or preserving.This not only can cause the infringement of agricultural film itself, produces big and small leak on its surface, makes agricultural film lose the performance of insulation, has caused indirect crop production reduction; And in mouse and insect get into booth the time, can directly gnaw farm crop, cause the direct underproduction.
The main method that adds sterilant that adopts obtains to have protection against rodents insect protected ability in the agricultural film at present.Yet along with the agricultural film increase of duration of service, sterilant can constantly be moved to the surface of film, evaporate in the air, flow in the soil through rainwash, environment is produced pollute.In addition, will directly murder mouse, worm extremely, break original food chain, destroy the eubiosis.
2) because airborne dust granules is more, along with the agricultural film increase of duration of service, can deposit one deck dust on its surface, had a strong impact on the light transmission of plastic sheeting for farm use, reduced crop yield.The work-ing life of also having reduced agricultural film simultaneously.
Method commonly used at present is after waiting agricultural film surface deposition at night one deck dust, adopts artificial method of scrubbing agricultural plastic film to remove dust, and practical effect is also not obvious, and has improved manpower greatly.
3) temperature in the agricultural film on daytime is very high, can improve the photosynthesis of farm crop.But the heat in the evening soil can slow release come out, and through being discharged into behind the agricultural film in the outer air of film, its heat insulation effect can be descended greatly.
At present less relatively about the research of agricultural film night insulation, mainly adopt evening at the outer one deck insulation roller shutter that increases of plastic sheeting for farm use, practical effect is also not obvious, and has improved manpower greatly.
If can work out a kind of multi-functional agricultural film, have multiple effects such as protection against rodents insect protected, automatically cleaning, diffuse-reflectance, in the raising the output that improves farm crop, can prolong the work-ing life of agricultural film greatly, reduce the pollution that agricultural film produces environment.
