摘要
试验在上海和黑龙江2个地区进行,于扁豆生长2～9叶期作不同的掐尖处理,分析其对扁豆主要农艺性状及产量的影响.结果表明：于扁豆生长2～5叶期进行掐尖,可以有效控制扁豆的蔓生特性,降低植株高度,控制倒伏在1.3～2.4级,植株提早开花7.3～10.7 d,采收提前4.6～8.3 d,茎杆鲜重比对照减少58.0％～76.7％,鲜荚数量为34.0～50.7个/株,鲜荚重283.3～403.5 g/株,经济系数为0.216～0.405.
Different topping treatments of Lablab purpureus plants at 2-9 leaf stage were carried out in two areas of Shanghai and Heilongjiang to investigate the topping effect on the agronomic traits and yield.The experimental results showed that topping the plants at 2-5 leaf stage could effectively control the plants＇ sprawling character,decrease the plant height,lower the degree of lodging to 1.3-2.4 levels,make the flowering time 7.3-10.7 days earlier and the picking time 4.6-8.3 days in advance,and reduce the fresh haulm weight by 58.0%-76.7% ;The number of fresh pods was 34.0-50.7 per plant,the fresh pod weight was 283.3-403.5 g per plant,and the economic coefficient was 0.216-0.405.
