| 摘 要： | 研究了不同覆膜方式对旱作大豆产量和水分利用效率影响。结果表明,秋季覆膜的周年栽培模式可有效蓄保秋冬闲期土壤水分,大豆临播前0~100cm土层贮水量比常规覆膜或传统露地增加30.5mm,土壤贮水量的增加可有效缓解大豆生长前期土壤水分不足而造成的水分胁迫;周年覆膜大豆产量为3228.7kg/hm2,较常规覆膜和传统露地分别增产19.0%和40.8%,水分利用效率为10.3kg/(hm2.mm),较常规覆膜、传统露地分别提高10.8%和37.3%。

| Abstract: | According to rainfall characteristics and soybean production in the Loess Plateau,effects of different plastic film mulching modes on water use efficiency(WUE)and yield of soybean were studied.The results showed that soil water content increased obviously under the treatment of whole year mulching cultivation(WYMC).The soil moisture storage of soybean under WYMC of 0 to 100 cm at the seeding stage increased 30.5mm compared with conventional mulching cultivation(CMC) or traditional open field cultivation(TOF... |
