Abstract

Abstract:

In order to improve the pasture yield of alpine meadow and effectively recover the light-degraded grassland, the influences of different nitrogen rates on alpine meadow grassland community, aboveground biomass and soil nutrients were studied using random block design with urea as fertilizer. The results showed that with the increase of N addition, both species richness and the diversity decreased,and the vegetation coverage, height, aboveground biomass and grass yield increased significantly(P<0.05). In certain range of increasing nitrogen application, total nitrogen, phosphorus, available nitrogen, and organic matter were gradually increased, available phosphorus increased at first and then decreased gradually after reaching the peak value, and the pH showed a decreasing tendency. These findings suggested that adding nitrogen could improve soil quality, and 150 kg·hm^-2 is the best option for economic benefits.

摘要：

为提高祁连县高寒草地草场牧草产量、有效恢复轻度退化草地，采用随机区组试验，以尿素作为氮源，探讨不同氮肥水平对祁连地区轻度退化草地群落结构、地上植物量以及土壤养分的影响。结果表明：不同施氮水平处理的高寒草地植物群落物种丰富度、多样性指数均减少，植被盖度、高度显著增加（P<0.05），地上植物量与禾草地上植物量显著提高（P<0.05）。随着施氮量增加全磷含量、速效氮含量、有机质含量呈逐渐增加趋势，而速效磷呈先增加后减小趋势，pH值呈逐渐减小趋势。结论：施氮对高寒草地土壤养分有改善作用，150 kg·hm^-2为最适施肥量。
