近年来在棉花生产上存在的主要问题是棉铃虫危害猖獗,农民为此过多施用农药而造成种植棉花投入增多效益降低,因而严重挫伤了农民种棉积极性。从一九九七年开始我们引进示范了抗虫棉,把高科技成果直接应用到棉花生产当中很受农民欢迎,为了掌握抗虫棉生长发育规律,摸索出相适应的栽培技术,今年我们进行了抗虫棉较大面积的示范和栽培试验。取得了可喜的成果。
In recent years, the main problem in cotton production is that the bollworm endangers the epidemic. Peasants use too much pesticide for this reason, which leads to the decrease of the benefits of increased cotton input. As a result, they have seriously dampen the enthusiasm of peasants in planting cotton. Since 1997, we have introduced and demonstrated insect-resistant cotton, which is very popular with farmers for applying high-tech achievements directly to cotton production. In order to grasp the law of growth and development of insect-resistant cotton and find suitable cultivation techniques, we conducted this year A large area of insect-resistant cotton demonstration and cultivation experiments. Has made gratifying achievements.
