摘  要:
通过秋季对紫花苜蓿铺膜播种,冬季封冻后覆土的方法进行种植,来年返青后对其返青时间、小区产草量、灌水次数和灌溉量、土壤含水量、平均株高、主根长度、侧根数量、茎部分支数等指标进行观测、分析,并对其5年的经济指标用试验结果进行换算分析。结果表明:应用紫花苜蓿铺膜覆土后比对照组节水47.9%,增产15.6%的同时能提高33.1%的经济效益。

摘  要:
Medicago sativa was planted by spreading film in autumn and covering soil after freeze-up in winter,then the indexes,such as green up time,grass biomass,irrigation times and volume,soil moisture,average plant height,axial root length,lateral root number and branch number,were measured and analyzed.And conversion analyses of the economic indexes in five years were conducted based on the experiment data.The result showed that cultivating Medicago sativa with film mulch and soil covering could save water by 47.9% than that of the control group,increase output by 15.6% and economic benefit by 33.1%.
