一、试验目的棉花是我区重要的经济作物,对国民经济建设和农村经济发展有着举足轻重的作用,是当地农民致富奔小康的重要经济支柱。1993年以来国内其他重要棉产区棉铃虫大发生,近几年我地区也遭到棉铃虫的严重危害,给棉花生产带来了很大威胁,造成了极大的经济损失。为保证棉花生产持续稳步发展,国家级科研机关已培育出一系列抗虫棉的新品系,为了尽快地使抗虫棉在我地区生产中发挥作用,进行抗虫棉品种的引种试验尤为重要。
First, the purpose of the experiment Cotton is an important economic crops in our region, plays an important role in the national economic construction and rural economic development, and is an important economic pillar for local farmers to get well-run. Since 1993, the major cotton bollworm occurred in other important cotton producing areas in our country. In recent years, the cotton bollworm has also been severely endangered in our region, posing a great threat to cotton production and causing tremendous economic losses. In order to ensure the steady and steady development of cotton production, a series of new strains of insect-resistant cotton have been bred by national scientific research institutes. In order to make the insect-resistant cotton play a role in the production in our region as soon as possible, it is especially important to introduce the varieties of insect-resistant cotton.
