【摘要】 以2004年通过不同手段塑造高矮配置栽培模式对棉花产量的影响为依据而进行。结果表明:仅通过单纯化控及早打顶塑造高矮配置栽培模式不可行,通过晚打顶打大顶有利于根系建成、有利于塑造理想冠层结构、有利于棉田通风透光、有利于同步结铃、有利于机械化,可以将公顷理论株数从27万株增加到38.25万株,增加棉花产量24%左右。更多还原

【Abstract】 The effect on the yield of cotton was studied by using different cultivation system with different height configuration and different varieties.The result showed that simply chemical control or early topping to figure different height configuration model was unworkable.Late topping a big night to figure different height configuration model,it were conducive to built root roof and create an ideal crown level structure,it were also conducive to cotton ventilation transmittance,synchronize bolls,and mechanization.The number of plants could increase up to30 000 from 18 000,the yield of cotton would increase about 24%.更多还原
