利用抗病品种是防治棉花枯萎病的一个经济、有效措施。目前我国推广抗病品种种植面积已达200万余亩,对减轻病害,提高产量,起着很大作用。全国棉花枯萎病防治研究协作组,每年将各地推荐的抗病、高产、优质品种,组织“区域试验”,统一进行评比。这种做法,既可以利用广大棉区的不同生态环境,对抗病良种的地区适应性,进行鉴定;又能起到示范推广作用,使科研成果
The use of disease-resistant varieties is an economical and effective measure to control cotton blight. At present, the planting area for popularizing disease-resistant varieties in our country has reached more than 2 million mu and played a significant role in alleviating diseases and increasing yield. The National Cotton Fusarium Disease Prevention and Control Research Collaboration Group, each year will be recommended throughout the disease-resistant, high-yielding, high-quality varieties, organizations, “regional test”, unified assessment. This approach can not only make use of the different ecological environment in the vast cotton area to identify the regional adaptability of disease-resistant varieties, but also serve as a model for promoting scientific research
