由性状特殊的结晶材料和常规成膜聚合物混挤而成的漫反射农膜,具有光转换效应和对可见光增透、红外光谱透过率较低等功能。用其作为栽培覆盖材料,对31个稻作、蔬菜品种进行试验,面积达13.2万亩,不少作物的增产效果比对照(覆以常规农膜)均达到极显著水平,被确认是一种较理想的膜种。经国家计委等审定,向全国推广。这种农膜在制作过程中掺入产生漫反射效应结晶
The diffuse reflectance agricultural film, which is a mixture of special crystalline materials and conventional film-forming polymers, has the functions of light conversion effect, penetration enhancement of visible light and low transmittance of infrared spectrum. Using it as a cultivation covering material, 31 rice and vegetable varieties were tested with an area of 132,000 mu. The yield increase of many crops was extremely significant compared with the control (covered with conventional agricultural film) and was confirmed to be a The ideal species. Approved by the State Planning Commission, etc., to promote the country. This kind of agricultural film is mixed in the production process to produce diffuse reflection effect crystallization
