转基因抗虫杂交棉轻简优化栽培技术研究

摘要

根据江苏沿海棉区的生产条件与气候特点,在总结高产经验和试验研究的基础上,提出了以“扩行减密、足肥轻控、留叶枝、迟打顶”为主要内容的转基因抗虫杂交棉轻简优化栽培技术路线,明确了本地区抗虫杂交棉高产栽培的具体技术条件和性能指标.%According to the conditions of cotton production and climate characteristics in the coastal area of Jiangsu province, and based on the summary of the high - yielding experience and experimental studies, this paper put forward the simplified and optimized cultivation technique route of transgenic insect -resistant hybrid cotton, which included "expanding the row spacing of cotton plants, reducing its planting density, applying enough quantity of fertilizer, conducting light chemical control, retaining leafy shoots, and delaying topping", and explicated the specific technical conditions and performance indexes for the high - yielding cultivation of transgenic insect - resistant hybrid cotton in this area.
