摘　　要：采用实地调查和野外试验相结合的方法,对东北黑土区五种埂带植物的固埂作用及经济效益进行分析,结果表明:红小豆和绿豆地上生物量、根长和根幅较大,地埂盖度分别达50%和56%,能够有效提高土壤抗崩解性;黄花菜地埂0-20cm、20-40cm和40-60cm不同土层土壤含水量为8.36%-11.62%,孔隙度为60.95%-63.21%;红小豆和绿豆地埂三个土层土壤有机质含量分别为5.03%-7.98和4.91%和7.94%,对地埂土壤理化性状改善效果显著。与红小豆地埂处理相比,芦笋和黄花菜处理产径流量分别提高60.3%和57.0%,产泥沙量分别提高60.7%和60.6%,红小豆植物地埂对径流泥沙控制作用最为显著。不同试验处理中红小豆和黄花菜净收入分别为23 220元/hm2·a和10 030元/hm2·a,芦笋净收入是红小豆净收入的14.5%。With a combination of methods based on field surveys and field test,the solid ridge effect of five kinds of ridge plants in black soil region of Norheast is carried out analysis.the results showed that：red beans and green beans,aboveground biomass,root length and width are larger,ridge cover respectively 50% and 56% ,can effectively improve soil resistance to disintegration;daylily ridge 0-20cm,20-40em and 40-60cm soil moisture for different soil layers 8.36%-11.62% ,porosity of 60.95%-63.21% ;red beans and green beans ridge,three layers of soil organic matter content was 5.03%-7.98 and 4.91% and 7.94% ,on the ridge of soil physical and chemical properties improved is significant.Compared with red bean processing ridge,asparagus and daylily handle runoff production increased 60.3% and 57.0% respectively, sediment yield increased 60.7% and 60.6% ,red bean plants ridge on runoff and sediment control is most significant.The net income of Red beans and Daylily of different experimental treatment was 23 220 yuan/hm^2·a, 10 030 yuan/hm^2· a,the net in-come of asparagus was 14.5% of Red Bean.
