江西种植外来不同熟性棉花品种的成铃分布

摘要

为研究外来不同熟性棉花品种在江西棉区的成铃分布情况及产量性状 ,于2014年引进黄河流域棉区的早熟、中早熟和中熟3种熟性的3个常规棉花品种在江西九江种植 ,分析其成铃分布及产量性状.结果表明 :中早熟品种中植棉2号的中下部及内围成铃率相对较高,籽棉产量最高.在当前栽培条件下 ,中早熟品种较适宜在江西棉区种植.%In order to study the bell distribution and yield of different maturity cotton varieties in Jiangxi area. In 2014 , the author introduced 3 conventional cotton varieties from the Yellow River cotton area which were 3 kinds of maturity and planted in Jiujiang of Jiangxi province. And in this trial ,the author analyzed the bell distribution and yield.The results showed that mid-early maturing varieties of Zhongzhimian 2 had the high relative boll rate in the middle lower part and inner circle , and the highest seed cotton yield. Under the current cultivation conditions , the mid-early maturing varieties were more suit-able for Jiangxi cotton region.
