随着立体高效农业的快速发展,棉田间套西瓜已逐步发展成为我国棉区特别是鲁西南地区的生产栽培模式。由于近年来气候条件的影响和棉铃虫抗药性的增强,棉铃虫(Hliothis armigera Hubner)防治不可避免地造成西瓜污染问题,这已成为广大消费者关注的焦点和农业上急需解决的大难题。日益增长的化学农药对西瓜的污染也迫使我们尽快寻找一种有效的防治新方法。为此,我们于1992年开始研究棉田无公害西瓜生产技术。本文报道的是无公害农药品种的筛选试验结果。
With the rapid development of three-dimensional high-efficiency agriculture, watermelon in the cotton field has gradually developed into a mode of production and cultivation in cotton area in our country, especially in southwestern Shandong. Due to the climatic conditions in recent years and the enhancement of the resistance of H. armigera, the prevention and treatment of the Hibothis armigera Hubner inevitably causes the problem of watermelon pollution, which has become the focus of consumers and the major problem urgently needed to be solved in agriculture. The growing pollution of chemical pesticides on watermelon also forced us to find an effective new control methods as soon as possible. To this end, we started in 1992 to study pollution-free watermelon cotton production technology. This article reports the screening results of pollution-free pesticide varieties.
