覆膜对绿豆产量和主要农艺性状的影响

针对冀西北地区绿豆生产单产水平低、经济效益差的现状，以当前常规品种张家口鹦哥绿豆不覆膜种植为对照，研究了覆膜种类对张绿1号产量和主要农艺性状的影响。结果表明：覆膜可使绿豆产量增加10.6％～28.2％，覆黑膜较白膜增产幅度大；覆膜可增加绿豆千粒重和单株荚数，在一定程度上提高了绿豆的商品性；覆膜可明显提高经济收入，张绿1号覆黑膜较常规品种不覆膜种植增收6741元/hm 2。张绿1号覆黑膜将成为生产上主要推广的种植模式。

Effects of Plastic Film Mulching on Yield and Main Agronomic Traits of Mung Bean

Aimed to the low yield and economic benefit on mung bean production in northwest of Hebei Province , taking the current conventional variety planted with no plastic film mulching as CK , the effects of different types plastic film mulching on the yield and main agronomic traits of Zhanglv No.1 were studied.The results showed that the yield could be increased by 10.6%-28.2% with plastic film mulching , the effects of black film was larger than that of white film.Film mulching could increase the 1000-seed weight and pod number per plant of mung bean, improve the commodity, then significantly increase the economic incomes, and the incomes of planting Zhanglv No.1 covered with black film was higher than CK by 6 741 yuan/hm2 , it will become the main promotion plantingpattern in mung bean production.
