| 摘 要： | 棉花产量的高低与棉花栽培技术措施密切相关。棉花冠层设计超高产栽培技术是以长江下游地区9、10月丰富的热量资源条件为基础,以提高棉花顶部经济性能为目标的栽培技术措施的集成与优化,通过推迟打顶时间,推迟治虫结束时间,增加盖顶肥用量,增加化控量,即"两推迟,两增加"4项技术的创新应用,实现单产较大幅度的提高。试验田测产及生产示范推广结果均表明,棉花冠层设计栽培技术能够明显提高棉花顶部成铃和单铃重,平均增产幅度在2成以上。这项技术的推广与应用,对于利用好本地区秋季优越的热量资源和棉花顶部优势结铃部位,实现棉花生产高产高效将起到积极的推动作用。

| Abstract: | The yield of cotton depends on cultivation methods used. Cotton canopy designing cultivation methods aimed at improving canopy economic productivity through collecting and optimizing traditional technologies based on advantageous thermal resources availiable in the low-reach of Yangtze River. Cotton canopy designing cultivation methods consisted of 4 techniques,i.e, put off topping time,put off ending time of spraying pestcides, added amount of fertilizer applied after topping,added amount of chemical control applied after topping.Results of experiment in the plot and demonstration in the mass area showed that canopy designing cultivation could increase cotton canopy bolling number and single boll weight significantly.lint yield was increased by more than 20% on average. Applicatoin and extension of Cotton canopy designing cultivation methods would have positively stimulating effect for higher yield and higher efficency cultivation by making full use of advantageous thermal resources available in autumn and superior boll bearing part of cotton canopy in low-reach of Yangtze River. |
