目前,郊区在春季早熟蔬菜上推广了透明膜,而有色地膜还很少应用。为了扩大地膜的应用范围,探讨其应用效果,我们在本院蔬菜试验队和郊县,进行了不同颜色地膜覆盖不同夏、秋蔬菜的试验。三年试验表明,在夏、秋季节只要选择适当颜色的地膜,就可获得蔬菜高产。试验材料应用的地膜,除透明膜外,还有银色、蓝色、绿色、紫色、黑色、乳白色膜和日本产的黑白双面膜(9224)、半透明的低浓度的
At present, the outskirts promote the transparent film on the spring precocious vegetables, while the colored film is rarely used.
