Unless they succeed , the gains of the Green Revolution will be largely lost even if the genes in legumes that equip those plants to enter into a symbiosis with nitrogen fixers are identified and isolated,and even if the transfer of those gene complexes , once they are found , becomes possible.

除非他们能取得成功，不然的话，绿色革命的产量收益将在很大程度上损失殆尽，即使豆科植物中使这些植物有条件进入到与固氮细菌共生关系的基因可被辨识出来和分离开来的话，且即使这些基因综合体，一旦被发现之后，其移植得以成为可能的话。

The results showed:(1)Nitrogen addition changed the soil physical and chemical properties, enhancing the content of NO3—- N available resources in the soil, increasing the plants height and cover, reducing the vegetation light penetration. With increasing of N addition, both the species richness and the diversity decrease sharply (P 0.001).(2)N addition increased the aboveground biomass significantly (P 0.05). With increasing of N addition, the aboveground biomass increased first then decreased, and the grasses biomass increased while the forbs and legumes biomass decreased.(3)There was a significant linear positive relationship between species richness and vegetation light penetration (P 0.05), and also between aboveground biomass and soil NO3—- N content (P 0.05). The relationship between aboveground biomass and species richness was negative upon enhanced N supply.

结果表明：（1）氮素添加提高了土壤中NO3—- N等可利用资源的含量，增加了植物群落植被的盖度，减小了植被的透光率，随着施氮量的增加群落中物种丰富度显著降低（P 0.001）；（2）氮素添加显著改变了植物群落地上生产力（P 0.05），随着施氮量的增加地上生产力呈现先增加后降低的变化趋势，各功能群中禾草生物量显著增加，而杂草和豆科生物量随施氮量增加逐渐减少；（3）物种多样性与植被透光率呈线性正相关（P 0.05）；地上生产力与土壤NO3—- N含量呈线性正相关（P 0.05）；随着施氮量的增加物种丰富度与生产力之间呈负相关关系。

The results of aboveground biomass variance analysis are that red clover, alfafa and crested dogstaiVs are significantly higher than the others, then fountain grass, Korean lovegass and tall fescue are followed.

地上鲜重方差分析表明：豆科牧草中的红三叶、紫花苜蓿和非洲狗尾草地上植物量显著高于其它草种，其次地上植物量较高的有东非狼尾草、云南狼尾草、云南知风草和高羊茅。
