- 摘要:
- 研究了陕北地区不同覆膜方式绿豆生长发育状况及产量、水分效应，并进行了投入产出分析。结果表明：绿豆垄膜覆盖（LM）、双沟覆膜（GM）和全膜覆盖（QM）三种覆膜方式均可促进绿豆生长发育，株高、茎粗、单株荚数、百粒重较对照（CK）明显增加；LM、GM和QM产量较对照分别提高112.59%、104.90%和100.27%，与对照相比差异达极显著水平（P=0.004＜0.01），水分利用效率提高124.24%、73.48%和81.82%；LM、GM和QM纯收入较对照分别增加156.98%、116.22%和64.98%。3种地膜覆盖方式中，以垄膜覆盖方式提高水分利用效率、增加绿豆产量和经济效益效果最好，且技术简便易行，推广应用前景较好。
- Abstract:
- In this study,the growth status and water effect of mung bean in different mulching methods were researched.The input-output analysis was also performed.The results showed that:(1) Plastic film mulching on ridge(LM),plastic film mulching on‘W’ ridge(GM) and plastic film mulching on whole plot(QM) could promote plant growth of mung bean.The plant height,stem diameter,pod number of one plant and weight of 100-grain were both significantly increased compared to no mulching(CK).(2) The yields of mung bean with LM,GM and QM were increased 112.59%,104.90% and 100.27% than CK respectively,and the differences were very significant than CK(P=0.004<0.01).At the same time,the water use efficiency with LM,GM and QM were improved 124.24%,73.48% and 81.82% respectively.(3) The net income of mung bean with LM,GM and QM were increased 156.98%,116.22% and 64.98% respectively.In the three plastic film mulching treatments,plastic film mulching on ridge was the most effective treatment in improving water use efficiency,yield and economic benefit of mung bean.Furthermore,the operation of plastic film mulching on ridge was very simple,therefor,the prospect for application and extention of LM is relative good.
