【摘要】 当前水资源越来越缺乏,特别是地处内陆的山西,十年九春旱,加之灌溉水利用率低,春季农田用水越显缺乏。农业科技工作者因此引进了W膜盖集雨补灌技术。试验表明,W膜盖集雨补灌技术不仅具有普通膜盖具有的增温保墒提墒增产增收作用,还重点表现出变无效水为有效水、集雨等特点。更多还原

【Abstract】 The current water resources become more and more scarce,especially Shanxi located in the landlocked,nine decades spring is drought,coupled with a low utilization rate of irrigation water,the using water of the farmland in the spring is even lacker.therefore agricultural scientists and technicians introduced W membrane gathering rainwater to irrigate farmland technology.Tests showed that W membrane gathering rainwater to irrigate farmland technology have not only the effects of rising soil temperature,adding soil moisture,increasing outturn and incomes and preserving soil moisture of ordinary membrane covered,but also the key performance making invalid water for the effective water,gathering rainwater etc.更多还原
