六十年代初,利用蚜虫喜趋金盏黄颜色的特殊色觉,人们成功地开展了黄皿预测蚜虫发生以及直接诱杀蚜虫的方法,在实际应用中收到了一定效果.随着对蚜虫这种生物学特性的深入研究,人们又进一步发现银色反光材料,能起到驱避蚜虫的作用.因而,从七十年代起,国外就有人在蔬菜上利用铝箔置放田间进行了这方面防治研究,亦收到了防止避病的效果,但由于耗费很大、方法麻烦,不能大面积地推广应用.我们自1979年以来,连续两年在油菜苗期,对秋蚜试用银粉带进行防蚜研究.结果表明,这种银色带不仅成本低、使用简便,而且能够有效地控制蚜虫和所传播的病毒病的发生,增产作用显著,值得进一步研究和完善.
The early 60s, the use of aphids like the color of the gold color Calendula color awareness, people have successfully developed a yellow dish to predict the occurrence of aphids and direct trapping aphids method, in practical applications have received some effect with aphids such creatures Further study on the characteristics of human beings has further found that the silver reflective material can play a repellent role in repelling aphids. Therefore, since the 1970s, some foreign countries have used aluminum foil to lay down fields in vegetables for prevention and treatment in this field. Received the effect of avoiding disease avoidance, but due to the large cost and inconvenience of the method, it can not be widely applied.We have conducted the test of aphid control on aphids with silver powder at rapeseed seedling stage for two consecutive years since 1979. Results It shows that this kind of silver ribbon not only has the advantages of low cost, easy to use, but also can effectively control the occurrence of aphids and transmitted virus diseases, and has obvious stimulation effect. It deserves further study and improvement.
