湖北省近10年棉花产量上下波动的原因是棉花面积受植棉政策的影响,棉花单产的高低受栽培技术棉田管理和投入、自然气候的影响。分析了科技植棉现状,在挖掘增产潜力上,要抓好棉田调整,坚持连片种植。重点抓好两萎病田、水旱轮作的调整;选用优良品种,提高大田用种纯度;狠抓壮苗早发技术的推广,延长有效生育期;重点搞好棉田面积和育苗配套,不同类型调节剂配套,棉田管理和种植方式配套;加强后期管理,防止棉花早衰。
The reason for the fluctuations of cotton output in the past 10 years in Hubei Province is that the cotton area is affected by the cotton planting policy. The cotton yield is affected by the management and investment of cotton cultivation techniques and the natural climate. Analyzed the status quo of cotton planting in science and technology, digging the yield potential, we must pay attention to adjust the cotton field, adhere to contiguous planting. Focus on two wilt disease, drought and drought rotation adjustments; selection of fine varieties, improve the purity of species used in the field; pay close attention to early seedling technology promotion, to extend the effective growth period; focus on well cotton area and nursery facilities, different types Conditioner, cotton field management and planting methods supporting; strengthen the late management, to prevent premature aging of cotton.
