| 摘 要： | 在大田栽培及桶栽两种栽培条件下,对甘蔗进行剪叶处理,分析剪叶处理对甘蔗开花的影响。结果表明:一定程度的剪除量会推迟甘蔗的始花期,推迟的天数因品种(系)而异;甘蔗经剪叶处理后,其抽穗率显著降低,降低程度因品种(系)而异;剪叶处理会给某些甘蔗品种(系)带来枯心死株等负面影响。

| Abstract: | Leaf cutting was conducted for sugarcane which planted in farmland and buckets,and the effect of leaf cutting on sugarcane's flowering was analyzed.The results showed that some degree of leaf cutting could postpone sugarcane's initial time of flowering,the number of the days be postoned was different for different variety;The earing rate of sugarcane was debased after leaf cutting,the reduced degree was different for different vatiety;Leaf cutting could bring negative effect on the growth of sugarcane,such ... |
