对黄河源区黑土滩上建植的垂穗披碱草人工草地，利用太阳能提灌系统进行喷灌试验，通过50天的灌溉试验后，对人工草地的地上、地下植物量和土壤水分进行了研究。结果表明：灌溉区的地上总植物量、禾草和莎草均高于对照区（P〈0．05），而灌溉区的杂类草地上植物量低于对照区（P〉O．05）；灌溉区土层深度在0—10cm、10～20cm、0—50cm的地下植物量高于对照区（P〈0．05），而灌溉区土层深度在20-30cm、30—40cm、40-50emmet植物量和对照区相比变化差异不显著（P〉0．05）；灌溉区每个土层土壤水分均显著高于对照区（P〈0．05）。

The above .2 ground and under - ground biomass-an-d the soil moisture in the Elymus nutans artificial grassland established in Black - soil - beach of the area of Yellow River source were studied by solar energy sprinkling irrigation for fifty days. The results showed that the above - ground total biomass, the above - ground biomass of grass and sedge in the irfigacion area were higher than that in the control area （ P 〈 0.05 ）, while the one of weed in the irrigation area was lower than that in the control area（ P 〉0.05）. The under- ground biomass at 0 - 10,10- 20,0 -50cm soil layer in the irrigation area were higher tham that in the control area. There was not significant difference between the underground biomass in the irrigation area and in the control ground at 20 -30,30 - 40,40 - 50cm soil layer （P 〉 0.05）. The soil moisture of every soil layers in the irrigation area were significantly higher than those in the control area （P〈0.05）.
