Description
Technical field
The invention belongs to the agricultural film field, be specifically related to a kind of biodegradable weed removal mulch film and preparation method thereof.
Technical background
The plastics agricultural mulching has soil moisture conservation and heats effect soil, brings the volume increase good harvest for agricultural thereupon, is described as revolution for the third time after collecting chemical fertilizer and seed on the agricultural in China.China also is agricultural mulching production in the world and the maximum country of usage quantity at present, is 1.6 times of other All Countries usage quantity summations.
Yet, when plastic mulching cultivation technology brings great economic benefit to agricultural production and income, common ground film is because of can't recycling, cause serious white pollution problems for soil and environment thereupon, use common ground film to cause residual film to accumulate on soil plough horizon year by year year after year, cause soil compaction, permeability variation, root growth to be obstructed the succession crop underproduction.In addition, behind the common ground film nurse crop, formed the ecotope of an interior relatively-high temperature high humidity of film, both helped the crop germination growth, also help growing of weeds, weeds and crop strive water, strive fertilizer, so that influence the normal growth of crop, therefore, peasant household generally adopts the way of first herbicide spraying bonnet common ground film.But the operating method of spray herbicide lid common ground film is time-consuming, and destroys sealing medicine layer easily, reduces herbicidal effect; Simultaneously,, cause chemical injury of crops, contaminated soil easily, or occur because of the weedy inadequately phenomenon of consumption because the consumption of herbicide spraying is difficult to control; In addition, in some water-deficient areas, it is very difficult to fetch water, and also is difficult to carry out the preceding herbicide spraying of bud.
Biodegradable mulch film with weeding function is to have the weeding function that increases mulch film on the basis of biodegradable function at mulch film, thereby make mulch film have biodegradable and complex function weeding, therefore can reach better herbicidal effect, and can not produced residual film and pollute by microbiological degradation after using.Chinese invention patent CN1244549A " a kind of degradable polyethylene mulching capable of killing weeds and production method thereof and purposes ", its preparation method adopt polyvinyl resin, add degradation agents, weedicide and make it have the function of degraded; Chinese invention patent CN1260115A " a kind of wide-effect weeding degradable mulch film and production method thereof and purposes ", its preparation method also is to adopt degradation agents to make polyethylene ground film have degradation function, the evolution hybrid process blown film in twin screw extruder with weedicide and polyethylene makes it have weeding function.But what present weeding degradable mulch film mainly adopted is that polyvinyl resin prepares, do not have biolytic function, and owing to adopt the polyethene preparation weeding degradable mulch film, be subjected to the high influence of PE Processing temperature, its alternative weedicide kind is limited, and can cause the loss of weedicide in the course of processing.
Summary of the invention
The biodegradable weed removal mulch film that the object of the present invention is to provide a kind of biodegradable weed removal mulch film master batch and make with this weed removal mulch film master batch, it is the biodegradable weed removal mulch film of environment-friendly type that is easy to suitability for industrialized production.
