摘　　要：为了筛选出能够提高作物产量并减轻作物病虫害发生的转光农膜,在大棚栽培条件下,对转光农膜覆盖和普通农膜覆盖下甘蓝的生长情况和主要病虫害的发生情况进行了比较研究。结果表明,有些转光农膜能促进甘蓝生长并提高了产量,但均未表现出对甘蓝病虫害的防治作用。与普通农膜相比,除RB9901和RB9902膜下的甘蓝产量低于对照外,RB9903-2、RB9903-3、RB9903-1和RB9904膜下的甘蓝产量均高于对照,增产幅度为6.7%~20.0%。To screen light conversion shed films for increasing crop yield and reducing occurrence of diseases and insect pest,the growth situation of wild cabbage and occurrence situation of main diseases and insect pests covering with light conversion shed film and normal film under greenhouse cultivation conditions were compared.The results showed that some light conversion shed films can promote growth of wild cabbage and increase yield,but no control effects for diseases and insect pests of wild cabbage appeared.In comparison with normal films,except the yields of wild cabbage under films of RB9901 and RB9902 were lower than that of control,the yields of wild cabbage under films of RB9903-2,RB9903-3,RB9903-1 and RB9904 were higher than that of control,and the increasing range was 6.7%~20.0%.
