据称,在玉米周围种植芥子,可防止所谓“绿色植物害虫”生长。每当玉米成熟时,这种害虫就开始出现,但若欲以农药加以清除似乎不大实际。因为这种害虫更喜欢吃芥子,如在玉米周围种上芥子,将这种害虫引诱至芥子叶上,随后将芥子叶割除,就达到了灭虫的目的。
It is said that planting mustards around corn prevents the so-called “green plant pests” from growing. This pest begins to emerge whenever maize matures, but it seems less practical to remove it with pesticides. Because the pests prefer to eat mustard, such as planting mustard around the corn, the pest lure mustard leaves, and then cut the mustard leaves, to achieve the purpose of pest control.
