Both lixiviation and heating digestion methods were used in determination of potassiumand calciumin alfalfa.

牧草在畜牧业发展中起着非常重要的作用，而作为牧草生长发育所必需的矿质元素钾和钙，是则保持牧草营养价值的重要成分[1，2]。

In the fenced plot of site A, the seed percentage of annual and biannual herbs in soil seed bank reserve was very high, and the percentage was even higher in the unfenced plot.

羊草样地围栏内外土壤种子库内的种子均以一、二年生牧草为主，远多于多年生牧草的数量。而围栏外一、二年生牧草在种子库总贮量中所占的比例更高。

In the aspect of grass cold tolerance, these ten grasses were classified into three types by the cluster analysis, based on winter survival adaptability and LT50 measured under low temperature treatment. High cold tolerance: Bromus biebersteinii,Bromus inermis,Festuca arundinacea, Agropyron desertorum,Elytrigia elongate, Phleum pretense; medium cold tolerance: Festuca rubra, Agropyron smithii,Dactylis glomerata; low cold tolerance: Phalaris arundinacea.

禾本科牧草在耐寒性方面，根据牧草越冬适应性表现和低温处理下用电导法得出的半致死温度， 10种牧草进行聚类分析结果表明：耐寒性强的是草地雀麦、无芒雀麦、苇状羊茅、沙生冰草、长穗偃麦草、猫尾草；耐寒性中等的是紫羊茅、蓝茎冰草、鸭茅；耐贫瘠性最弱的是草芦。

As temperature elevatory, grazing grows Ji Youyan's long trend, grow to grazing have certain positive effect, but the live through the winter that also is helpful for plant diseases and insect pests on the other hand, adverse to the growth of grazing of the coming year.

随着温度的升高，牧草生长季有延长的趋向，对牧草生长具有一定的积极功能，但另一方面也有利于病虫害的越冬，对来年牧草的生长不利。

Quality forage has much higher content of protein and lysine than conventional one. Generally, the content of protein in the gramineous is ranged from 13 percent to 15 percent and from 18 percent to 24 percent in the legume.

牧草蛋白质含量和赖氨酸含量都比秸秆等传统饲料高，一般禾本科干草的蛋白质含量为13%～15%，豆科牧草为18%～24%，并且牧草中所含的蛋白质更容易被家畜消化吸收。

牧草蛋白质含量和赖氨酸含量都比秸秆等传统饲料高，一般禾本科千草的蛋白质含量为13%～15%，豆科牧草为18%～24%，并且牧草中所含的蛋白质更容易被家畜消化吸收。

This article summarizes the researching evolu tion of the wild forage grass of leguminosae from both home and abroad, making a preliminary analysis of the issues on how to make use of it for comprehensive d evelopment and utilizations

摘 要：在对国内外野生豆类牧草研究进展进行综述的基础上，对我国豆科牧草的划分、营养价值等进行论述，初步分析了如何利用野生豆类牧草搞好综合开发利用的问题

The optimization techniques to adjust and control stocking rate were as follows: firstly, a quantity of beef cattle should be eliminated through selection or sell before damp off of pasture; secondly, a quantity of rotational grazing districts should be left to be utilized for winter and spring during pasture growth midseason.

18.6 调控载畜量的优化技术是：第一，枯草期前淘汰部分牛只，减少冬春载畜量；第二，在牧草生长旺季，留下部分轮牧区作冬春放牧草地；第三，通过刈制干草、青贮饲料将6—8月牧草生长高峰期的过剩牧草储备或转移到翌年3—5月产犊期利用。

Nine wethers selected from a group at 2-years-old of age were fed with fresh mixtures of Leymus chinensis (30%), Cleistogenes squarrosa (20%) and Artemisia frigida (50%) in known proportions and amounts for 14 days. Artificial QSM capsules were dosed during the experiment. The samples of herbage and feces were collected daily for 7 days and dried for analysing the n-alkane concentration by a gas chromatography. The results showed that there was a difference in concentration of n-alkanes among 3 species forages, and fecal recoveries of n-alkanes linear increased with increasing carbon chain lengths.

于2004年秋季在中国科学院内蒙古草原生态系统定位研究站用不同放牧演替阶段的优势植物羊草、糙隐子草和冷蒿按一定比例混合组成日粮，饲喂9只2岁羯羊，每只羊投喂一粒QSM胶囊，试验期内每天记录绵羊实际牧草采食量、采食成分和排粪量，利用气相色谱分析牧草和粪样的链烷含量，应用链烷技术测定绵羊的排粪量、不同牧草采食比例和总干物质采食量，并与实际值进行比较。
