我省是全国主要产棉区之一,常年植棉面积达一千多万亩,总产皮棉五亿多公斤,棉花生产在农业生产中占有极其重要的地位。但是,由于我省气候温和,棉花病虫害发生种类多,危害时间长,因此,给棉花生产带来十分严重的损失。选用经济、安全、有效的农药防治棉花病虫害是一个急待解决的问题。我们从一九八二年至一九八五年对速灭杀丁(日本住友化学株式会社生产提供)防治棉花害虫的应用技术进行了开发及研究。先后组织了三十多
The province is one of the major cotton producing areas in the country. The annual cotton planting area amounts to more than 10 million mu and the total output of lint more than 500 million kilograms. Cotton production plays an extremely important role in agricultural production. However, due to the mild climate in our province, there are many kinds of cotton pests and diseases and a long time-lapse of time, thus causing serious losses to cotton production. The selection of economic, safe and effective pesticides to control cotton pests and diseases is an urgent problem to be solved. From 1982 to 1985, we developed and researched the application technologies for the control of cotton pests in Japan (Sumitomo Chemical Co., Ltd., Japan). Has organized more than thirty
