不同覆盖方式对黑豆光合速率及产量的影响

Effects of Different Covering Methods on Photosynthetic Rate and Yield of Black Bean

针对榆林市黑豆产量长期低而不稳的现状,在2012年5月~2013年10月开展全膜覆盖(QM)、膜际栽培(MJ)、秸秆覆盖(JG)、双沟覆膜(SG)、裸地(CK)五种覆盖方式对黑豆光合速率和产量影响的研究,旨在筛选出适合榆林地区黑豆生产的旱作节水栽培方式。结果显示,膜际栽培(MJ)在促进黑豆生长发育和实现增产方面的效果明显。

In order to select the suitable method for dry farming and water saving cultivation techniques of black beans production in the region of Yulin,the effects of whole membrane covering the event（ QM）,plastic film mulching on ridge（ MJ）,straw mulching（ JG）,plastic film mulching on W-shaped ridge（ SG） and bare land（ CK） on the growth and yield of black bean are studied. This research indicates that the effects of plastic film mulching on ridge（ MJ） in promoting black beans to grow and develop and implement production increase are obvious.
