在重牧条件下，群落中多年生牧草和适口性较好的一年生牧草相继退出，劣质一年生草占绝对优势；

Perennial plants and palatable annual plants withdraw in succession from grassland and annual plants of poor quality dominate absolutely under overgrazing ;

中牧区牧草优势种更替较慢，多年生牧草与一年生牧草优势度比为1∶4左右；

The change of domination plants is slow and domination index ratio between perennial plant and annual plant is 1:4 under moderate grazing ;

多年生牧草在产出上的周期性变化不仅会导致成本上发生变化，也会导致项目新增收入的变化和与收入相关的成本间接发生变化；

Periodical output changes of herbage not only lead to cost changes , but also changes in project incremental income and relative cost indirectly ;

这些结果对禾本科牧草幼胚的发育研究具有重要参考价值，对羊草等多年生牧草的杂交育种具有潜在利用价值。

These results provide useful information for research of immature embryo development in Gramineae forage , and have latent utilization value for crossbreeding of perennial grasses .

结果表明在防风蚀的作用效应中灌木>多年生牧草>林木>作物>一年生牧草；

The results indicated that the effectiveness of different plant types in increasing soil resistance to wind erosion were : perennial shrubs > perennial pasture > forest > annual pasture > forage crops .

结果还表明，封育4年草地产量比封育前增长87.8%，多年生牧草占总产比重增加5.6倍；

The results showed also that forage yields and perennial grass yield ratio af - ter fencing for 4 years increased by 87.8 % and 5.6 times more than those before fencing , respectively ;

Collection , Conservation and Utilization of Forage Resource in the National Field Genebank for Perennial Forage ( NFGFPF ) The annual ryegrass is one of Gramineae forages with high production and rich nutrition .

祁连山中段开垦的温性草原，经退耕种植多年生牧草&苜蓿7年后，土壤有机碳、全氮含量分别显著提高了63-118%，23-49%。

( 4 ) After Temperate Grassland cultivation distributing in the middle of Qilian Mountain plant perennial grass-alfalfa for 7 years , SOC and TN contents significantly increased by 63-118 % and 23-49 % .

对一年生作物和多年生牧草混播条件下，对多年生牧草的栽培进行了研究，并通过不同多年生牧草生产性状的差异分析，筛选出最优的一年生保护作物。

The cultivation technique of the perennial forage is researched under the mixed sowing system . According to the discrepancy analysis of the productivity of the different perennial forage , the optimal annual protective crop is selected .

灌木、多年生牧草与林木则全年覆盖着地面，覆盖度的月动态变化表现为灌木＞多年生牧草＞林木。

While the shrub , perennial pasture and woodland in hill having covered the ground all the time , and theirs monthly dynamic cover behave shrub > perennial pasture > woodland in hill > crop > annual pasture .

初步研究结果表明，在青海环湖地区草原性气候区土壤缺乏灌水的条件下，油菜对多年生牧草第1～2年生长的影响最小，其次是对燕麦、青稞的影响最大。

The study shows that there is a great deal effects of the annual crops on the growth of the perennial forages in the first and second year under the condition of lack of irrigation and the steppe climate on Qinghai Lakeside .

从牧草返青到开花，植物处于短枝阶段，适度放牧并不对多年生牧草的健康和活力造成危害，因为植物会弥补其失去的叶片。

From " green-up " to flowering ( while the plants are in the short-shoot stage ), proper grazing is not particularly detrimental to the health and vigor of perennial grasses because the plants replace the leaves as they are removed ( assuming environmental conditions are conducive for growth ) .
