| 摘 要： | 为研究施肥对玛曲高寒沙化草地地上生物量的影响,设置不施肥(CK)、施有机肥(O)、施氮肥(N)、施磷肥(P)、施氮磷肥(NP)、施有机肥和氮肥(ON)、施有机肥和磷肥(OP)及施有机肥和氮磷肥(ONP)等8个处理,采用样方法对玛曲高寒沙化草地植被盖度和地上生物量进行研究。结果表明:在2006年和2007年,3种肥料混施处理(ONP)比对照盖度增加了7%,地上生物量均为最高。2007年施肥处理的地上生物量在不同生长季均比2006年显著增加。氮、磷肥和有机肥组合的处理(ONP)对增加高寒沙化草地的地上生物量效果最显著。 |

| Abstract: | In order to study the effects of fertilization on aboveground biomass, a field experiment was conducted including 8 fertilization treatments： CK （no fertilization）, organic manure （O）, nitrogen （N）, phosphate fertilizer （P）, nitrogen and phosphate fertilizer （NP）, organic manure and nitrogen （ON）, organic and phosphate fertilizer （OP）, and the organic manure, nitrogen and phosphate fertilizer （ONP）. The coverage and aboveground biomass had been studied through quadrat sampling method in this paper. The results showed that the coverage of ONP treatment increased by 7% compared with CK and had maximum aboveground biomass in 2006 and 2007. The aboveground biomass of all fertilization treatments in 2007 was significantly higher than in 2006 in different growing seasons. The treatment of nitrogen, phosphorus and organic fertilizer （ONP） reached the most significant effect among all treatments in Maqu alpine desertification meadow. |
