本文主要研究内容
作者李彬,戚迎龙,赵沛义,赵举,尹春艳,任永峰,高宇,刘虎,丁艳宏（2019）在《模拟降雨条件下垄膜方式对土壤蓄水效应影响》一文中研究指出：通过小区试验和模拟降雨的方法,分析了旱作区不同降雨量下不同垄膜覆盖方式对土壤水蓄积效应的影响。结果表明:随着模拟降雨量增大,0～50 cm土层的土壤贮水量及其增量增大,表现为垄作全覆膜(QLM)>垄作半覆膜(BLM)>传统平作(CKM)。对于沙壤土,垄作全覆膜较传统平作贮水量增量增大0.9～3.4 mm,产流效率为10.50%～27.50%,蓄墒增加率为36.21%～95.65%;垄作半覆膜较传统平作贮水量增量增大0.6～2.1 mm,产流效率为5.00%～15.00%,蓄墒增加率为17.24%～55.26%。对于壤土,垄作全覆膜较传统平作贮水量增量增大1.7～6.8 mm,产流效率为31.00%～45.83%,蓄墒增加率为75.68%～95.77%;垄作半覆膜较传统平作贮水量增量增大1.4～4.2 mm,产流效率为15.00%～35.00%,蓄墒增加率为75.68%～95.77%。试验验证了不同覆膜方式的集雨效果、土壤蓄水和保墒效应,全覆膜和半覆膜垄上沟播模式能够起到集雨增温保墒作用,可提高土壤蓄水,实现区域降水资源的高效利用。
