Background:Root lifespan is an important trait that determines plants’ ability to acquire and conserve soil resources. There have been several studies investigating characteristics of root lifespan of...
To understand root dynamics of the native, perennial clonal grass Leymus chinensis in Inner Mongolia steppe, we examined spatial and temporal effects of N addition on root survivorship and longevity t...
Grassland degradation due to over-grazing causes severe ecological and economical problems in the semi-arid grasslands of Inner Mongolia, PR China. The development of sustainable management systems is...
The nutrient composition of pasture, voluntary intake and digestibility of diet ingested by goats grazing on an introduced Leymus chinensis pasture were measured across spring (May), summer (July), au...
The effects of rewatering after different periods of soil drought stress on the photosynthetic capacity of Leymus chinensis in pots were investigated. The plants were subjected to short-term (10-d), m...
【目的】颗粒状土壤有机质(particulate organic matter,POM)是土壤有机质比较活跃的成分,受施肥、耕作及管理等多种因素的影响,本文研究连续5年施用氮肥和羊粪对内蒙古草原围栏封育的表层土壤颗粒状有机质的含量及其化学结构的影响。【方法】采用物理分组法获得游离态颗粒状有机质(FPOM)和包被态颗粒状有机质(OPOM),并用13C核磁共振法测定其化学结构。【结果】施用氮肥的土壤p...
