Stem and Dongmu-70 rye grass (Secale cereale L.) stem. The diameter, length, weight and linear density of stem were measured after sample collection. Shearing force was measured. Meanwhile, the content of moisture were measured, neutral detergent fiber acid detergent fiber lignin, cellulose and hemicellulose were measured. Three Xiaowei sheep were used to determine in situ degradability in 48 h of DM and NDF of alfalfa stem and rye grass stem.

采集2种牧草后，测定茎直径、长度、重量和线性密度，测定剪切力、中性洗涤纤维、酸性洗涤纤维、木质素、纤维素及半纤维素含量，用尼龙袋法测定干物质、中性洗涤纤维48h瘤胃降解率，比较各项指标随茎直径变化的规律，探讨剪切力与各项指标之间的相关性。

CH4 uptake, N2O and CO2 emission, have their own relatively fixed seasonal variation patterns in the ungrazed and the grazed grasslands.

禁牧草原及放牧草原吸收CH4、排放N2O和CO2各自有其相对固定的季节变化形式，草原和大气交换温室气体通量的季节变化形式主要受年度气候变化所控制，而土壤、植被类型、降雨量等禁牧因素和放牧强度等人为因素仅影响排放强度。

In order to evaluate the influence of zokor's consuming and excavating on pasture, the vegetation on zokor mounds was studied by index of grassland quality. The result indicates that,with the succession, the index of grassland quality increases strikingly.

为了评估鼢鼠觅食掘洞行为对草地牧草质量的影响，采用草地质量指数分析了鼢鼠土丘植被状况，结果表明：随着演替的进行，鼢鼠土丘草地质量指数显著增加。

Under the auspices of MOP and MOA in the last ten years, an integrated technical study on forage species selection, variety combination, seed treatment, land surface treatment, proper seeding time, airplane type selection, maintenance after seeding and reasonable utilization was conducted in the county, focused on aviating seeding and protection and utilization.

飞播种草是沙化、退化草地治理的重要技术措施之一，近10年在财政部、农业部的大力支持下，全国开展了以&飞播种草＋保护利用&为核心，对牧草筛选、草种组合、种子处理、地面处理、适时播种、机型选择、播后管护、合理利用8项关键技术进行组装和研究，集成应用在北方沙化退化草地区等6个不同生态区域中。
