棉花新品种鄂抗棉3号是用鄂光棉和荆3247杂交,再注入中2535的抗病基因,经10年强压力逆境条件下系统选育出的高产(比中棉12增产9.68%~19.49%)、高抗枯萎病(病指3.60)、耐黄萎病(病指34.40)、适应性广的高优质陆地棉品种;适宜的栽培密度为37500~52500株/hm2,栽培管理上应抓好种子处理、配方施肥、全程化调和防治虫害。 The cotton variety E-resistant cotton 3 was crossed with E-Guangmian and Jing 3247 and then injected with the resistance gene in Zhong-2535. After 10 years of stress-resistant conditions, the high-yielding cotton (yielding 9.68 % ~ 19.49%), high resistance to Fusarium wilt (disease index 3.60), Verticillium wilt resistance (disease index 34.40), wide adaptability of high quality Upland cotton varieties suitable planting density of 37500 ~ 52500 Plant / hm2, cultivation and management should do a good job of seed treatment, formula fertilization, the whole process of reconciliation pest control.
