草地

Iv With grazing-height increased and the utilization period deferred, the regrowth-height of needle grass increases accordingly, and reaches the highest height to 17cm.

各草地类型相对日生长量与草群组合或结构有关，草群组合或结构越简单，草地相对生长量延续的时间越短，反之越长。

The main researching contents included as following:relationships betweenspecies diversity,community richness,vegetation succession,soil volume weight,solu-ble Na+concentration and five soil chemical elements(N、P、K、Ca、Mg)concentrationwith grazing intensities in the grassland.Relationships between concentrations,re-serve pools of plant nutrient materials,including five macroelements(N、P、K、Ca、Mg),crude protein,crude fibre,crude fat and total nonstructural carbohydrate,and their allocations in defferent plant parts with grazing intensities in thegrassland.Effects of grazing on Leymus chinensis population were also examined andthat more attentions were paid on the responses of many biological characteristics ofabove-and below-ground plant modules to different grazing intensities.Furthermore,in the respects of plant production,survival rate,tillering ability,total nonstructuralcarbohydrates content and others,the effects of one years different defoliationpatterns on the vitality of Leymus chinensis population were detected.

主要研究内容有：放牧对羊草草地植被和土壤的影响，致力于物种多样性、群落丰富度、植被演替和植物生产量、以及土壤容重、土壤水溶性Na+含量和五种土壤大量营养元素(N、P、K、Ca、Mg)的含量等土壤理化性状与放牧强度关系的分析，分析了不同放牧强度与羊草草地草群和羊草种群地上和地下各植物部分中多种营养物质的浓度、贮量及其分配的关系；放牧对羊草种群的影响，注重了羊草种群的地上与地下各植物器官对不同放牧强度的反应和适应性变化，最后，从植物生产量、存活率、分蘖能力以及总非结构性碳水化合物含量等方面，探讨了不同人为去叶方式组合对羊草种群当年和次年生活力的效应。

The meadow stones glowed white-green and a flintywind worked over the meadow, scraped the fire low, then ruffled it into yellow silk sashes.

The introduction adaptation of Kentucky bluegrass varieties in Beijing is summarized. Indices including growing habit, turf quality, turf duration, winter and summer survival, disease resistance were analyzed.

该文根据3a多的试验，分析了草地早熟禾的生长特征和特性，以及形成草坪的质量、持续年限、越冬越夏性和抗病性等结果表明，草地早熟禾各品种差异十分明显，大多数品种比较适宜北京种植。

Cold stress caused by the low environmental temperature had brought great loss to the grassland animal husbandry in North.The study of composite feed for resisting cold stress was made in this experiment,in order to solve the problem on cold stress and ensure the heathy,stable and sustained development of grassland stock farming.

环境低温引起的冷应激给北方草地畜牧业造成了严重的损失，为解决这一影响畜牧业生产的难题，保证草地畜牧业的健康、稳定、持续发展，本试验对抗冷应激饲草料进行了研究。

According to the models of land use dynamic change, the research on the dynamic change on land use quantity, space structure and land use degree were carried during 1989 and 2001. The results of the research indicated that the area of cultivated land and saline land increased, and the area of meadow, water areas and wetland reduced within 12 years; The variety ratio of cultivated land, meadow, water areas and saline land changed relatively great; and variety ratio of forestland, land used for resident, industrial and mining changed more steady; The land use degree presented a reducible tendency.

研究结果表明，吉林西部在12年内耕地和盐碱地面积增加，草地、水域和湿地面积减少；总体上，耕地、草地、水域和盐碱地的土地利用变化率较大，林地、居民、工矿用地和湿地变化较平稳； 12年间土地利用程度呈减小趋势，全区十个县市中只有白城和扶余的土地利用处于发展期，土地生态环境相对较好，而其他地区由于土地生态环境呈现不同程度的恶化，导致可开发利用的土地资源逐年较少，土地利用潜力小。

The wholecharacteristic behavior of kentucky bluegrass is better than that of tall fescue and perennial ryegrass; while tall fescue is better than perennial ryegrass.
