原地放垡振动间隔松土对羊草草地质量的影响（Effect of Situ-vibration Spacing Scarifying Technique to Leymus chinensis Grassland）
原地振动间隔松土 羊草草地 植被特性
2010/12/28
以河北坝上地区羊草草地为研究对象，采用野外取样与实验室分析相结合的方法研究了原地放垡振动间隔松土对羊草草地的影响。结果表明，羊草草地经过原地放垡振动间隔松土处理后，土壤容积密度降低、毛管持水力升高和土壤含水率增加，同时土壤养分也呈现不同程度的优化；植物高度、盖度、密度和地上、地下生产力提高，优良牧草所占的比例有所增加，草地群落的植物多样性得到提高；在草地处理3年内平均每公顷每年增加收入155元。
Photosynthetic Recovery of a Perennial Grass Leymus chinensis after Different Periods of Soil Drought
Carbonic anhydrase Chlorophyll fluorescence Drought adaptation Gas exchange Leymus chinensis (Trin.) Tzvel. Rewatering
2009/7/23
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...
连续5年施用氮肥和羊粪的内蒙古羊草（Leymus chinensis） 草原土壤颗粒状有机质特征
氮肥 羊粪 游离态颗粒状有机质 包被态颗粒状有机质 固体13C核磁共振 内蒙古羊草草原
2008/9/18
【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...
