1998年我县引进试种杂交棉湘杂棉2号,皮棉平均单产(667平方米产量,下同)达到125.9千克,表现优质高产,比常规棉增产30%。杂交棉试种成功,使我们认识到,我县皮棉单产要从“九五”期间的75千克水平再上一个台阶,达到皮棉单产100千克,除了提高适用技术到位率以外,推广应用杂交棉可能是一个突破口。为了选择适合我县种植的高产优质抗病的杂交棉品种,以及在生产上可否应用杂交棉的F2
In 1998, the county introduced the hybrid cotton Xiangzamian 2, with an average lint yield of 667 square meters (up to 125.9 kilograms), showing high quality and high yield and 30% more yield than the conventional cotton. The success of the hybrid cotton trial so that we recognize that the county lint yield from the “95” during the 75 kg level to a higher level, to lint yield 100 kg, in addition to improving the availability of technology in place than rate, promote the use of hybrids Cotton may be a breakthrough. In order to select the suitable high-quality, high-quality and disease-resistant hybrid cotton cultivars planted in our county, and whether F2
