近年来,我国棉花生产滑坡,严重影响了国民经济发展。其主要原因是植棉比较经济效益低。但要与国际市场接轨,通过提高收购价格,改革流通体制等措施,提高经济效益,其潜力有限;而通过增加科技投入,降低植棉成本,增加经济效益,其潜力无限。为此,建议应大力提倡科技兴棉。主要是:1.合理用种。加快选育高产、优质、抗逆的优良品种;加速筛选、推广适宜当 In recent years, the decline of cotton production in our country has seriously affected the development of the national economy. The main reason is that cotton is more economical. However, in order to be in line with the international market and increase economic benefits through measures such as raising the purchase price and reforming the circulation system, its potential is limited. However, its potential is limited by increasing investment in science and technology, reducing cotton planting costs and increasing economic benefits. Therefore, it is suggested that we should vigorously promote science and technology to promote cotton. Mainly: 1. Reasonable use of species. Speed ​​up the breeding of high yield, high quality, anti-adversity of fine varieties; accelerate screening, promotion appropriate
