摘要
在田间试验条件下,以青花5号花生品种为材料,研究了花生覆膜"W"栽培法对花生植株生长动态的影响。结果表明:与覆膜"AnM"栽培法和常规覆膜栽培比较,采用花生覆膜"W"栽培法可降低株高,增加分枝数和有效分枝数,显著提高叶面积系数,且维持较高叶面积系数的时间较长;单株开花数量尤其是前期有效花数量较多,果针总数和入土果针数显著多于其他两种方法。花生覆膜"AnM"栽培法的综合效果优于常规覆膜栽培。因此,花生覆膜"W"栽培法是一项有利于花生植株健壮生长、促进有效花形成、便于集中结实的实用技术。
Under experimental field conditions, the research was carried out on the effects of W-shape plas- tic mulching method for peanut cultivation on the variation of plant dynamic growth, with Arachis hy- pogaea cv. Qinghua 5 as test material. The results showed that compared with AnM plastic mulching method and conventional plastic mulching method for peanut cultivations, the W-shape plastic mulching method for peanut cultivation can reduce the plant height, increase branching amounts and valid branching amounts, significantly improve leaf area index （LAD, and maintain the higher LAI for a long time. Moreo- ver, under W-shape cultivation method, there was more flowering quantity per plant especially at the early stage, more total number of fruit pin and fruit pin amount into soil than the other two methods. The com- prehensive effect of AnM plastic mulching method was better than the conventional plastic mulching meth- od. Therefore,W-shape plastic mulching method for peanut cultivation was a practical technique,which is favor of plant robust growth, promoting the valid flower formation, and centralized fruiting.
