1) topping a big night
打大顶
1.
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.
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。

2.
Compared with the conventional decapitation practice,smearing with 3×10~(-2) mmol·L~(-1) NAA(α-Naphthylacetic acid) after decapitation can increase biomass of the upper part of cotton plants by recovering of apical predominance,but had no significant effect on the middle-low part of plants.
与传统打顶处理相比,打顶后涂抹浓度为3×10-2mmol。
3.
In this paper,the change of hormone and nutrient absorption of cotton in fourth leaves from the top after decapitation is analyzed.

【诗文】：
西蜀冬不雪，春农尚嗷嗷。上天回哀眷，朱夏云郁陶。
执热乃沸鼎，纤絺成缊袍。风雷飒万里，霈泽施蓬蒿。
敢辞茅苇漏，已喜黍豆高。三日无行人，二江声怒号。
流恶邑里清，矧兹远江皋。荒庭步鹳鹤，隐几望波涛。
沉疴聚药饵，顿忘所进劳。则知润物功，可以贷不毛。
阴色静陇亩，劝耕自官曹。四邻耒耜出，何必吾家操。
