Persistence of grazing mixed pasture has been a key issue in environment conservation and sustainable utilizing of resources in karst region. Under moderate grazing with Corriedale sheep, the productivity and botanical composition of Trifolium pratense mixtures were studied over a 20-year period in karst region of southwest China. Four mixtures consisted of Trifolium pr...
用考力代绵羊轮牧，在牧前和牧后草地现存量(干物质，DM，drymatter)分别为1800~2500(草层高15~18cm)和900~1200kg·hm-2(草层高3~5cm)的适度放牧利用条件下，对亚热带最常见的豆科牧草红三叶与禾本科牧草的两两混播草地的群落生产力和持久性开展长期研究。20年的结果表明：适度放牧利用下，群落地上总生物量长期稳定，各组合间差异不显著，总盖度20a后仍高达97%以上；适度放牧有利于牧草的生产力持久性，红三叶、鸭茅、多年生黑麦草和黑穗画眉草都在群落中长期存在；群落净产量和持久性是尺度依赖的，群落长期净生产力以红三叶+鸭茅的最高(DM产量353.3g·m-2·a-1)(P.05)，对杂草侵入的抵抗力最强，而前10a红三叶+多年生黑麦草有很高的净生产力DM产量449.8g·m-2·a。。。

The pangola grass with different length was throwed by the free body falling method and the passing time was measured using two infrared ray sensors. The calculative terminal velocity V was calculated through the time and distance. The exeperimental terminal velocity V of grass with different length was measured by the floating method.
本研究之目的乃是以盘古拉牧草为研究对象，改变不同长度的牧草茎，首先以自由落体法，利用红外线感测器量测出时间，藉由时间与距离之关系，代入公式得到计算终端速度；其次以浮力法，量测出不同长度的牧草茎之实验终端速度。

The results show that NPP is larger in June and July than other growth periods, grass LAI and NPP change rapidly from May to June. Estimated error of 44 cases by the biomass model is less than 20%, which show that the biomass model is very good , the model can describe growing status. Photosynthesis and respiration are different because of different type grass , three types grass are more adaptive to desert environment and the biomass are also big, the grass types include Alhagi sparsifolia, Lycium ruthenicum and Reaumuria songarica. The grass biomass is influenced by many factors such as grass type, total cover and plant height et al.
结果表明，2005年牧草生长期内NPP的变化基本是6、7月份最大，其它月份较小，5～6月份是牧草叶面积变化比较大的时期，也是NPP变化比较显著的时期；生物量模型估算得到的44个样本的生物量误差基本都小于20%，说明模型能够反映牧草的实际生长状况；不同荒漠牧草对光的利用能力和对CO2同化能力有很大差异，骆驼刺、红砂、黑果枸杞是荒漠牧草生物量较大的牧草类型；牧草类型、牧草盖度以及平均高度是造成不同牧草产量相差较大的重要原因。

Uses method which the field investigation sample and the indoor analysis unify, 2007-2008 years live the unicast awnless brome lawn and the awnless brome and the alfalfa interlacing in the Inner Mongolian nationality university agriculture school test farm take 2 years mix broadcast the lawn and the colleague mix broadcast the lawn as the objects of study, have studied under the different sowing seeds way the forage grass to the soil physics and chemistry nature influence, finally indicated:the change tendency which under the different sowing seeds way increases the soil bulk specific gravity overall along with the soil layer depth to present after reduces first increases, is the 10-20cm soil layer is lowest; Looking from the 0-40cm soil layer's mean value, the unicast awnless brome lawn soil bulk specific gravity is smallest, the colleague mixes broadcasts the lawn soil bulk specific gravity to be biggest.
科尔沁草原是典型的农牧交错地区，长期以来，由于不合理利用草地资源造成该区生态环境严重恶化，农牧业生产受到严重影响[1]。建立高产优质的人工草地是解决我国高寒地区草畜供求季节不平衡的矛盾，促进草地畜牧业持续发展的关键措施之一[ 2]。无芒雀麦和紫花苜蓿都是营养价值高、适口性好、抗寒抗旱能力强的多年生牧草。将这两种牧草混播不仅能提高牧草产量和品质，延长草地使用年限，还能改善牧草的营养，提高牧草的适口性，有利于调制和青贮[3]。

There were a great deal of kinds of the grass with high quality and quantity fed to fish To determine the best symbiosis ecosystem of fish and grass on a closed system circulated yearly, several cold and warm grass was selected to analyse the adaptability and nutrition absorbed. It indicted that Lolium multiform Lam. and lemarthria compressa were the best option due to high adaptability of wetness, high coarse protein, fat and fibre and so on in the leaf, high biomass, high bio-filtration effect of N and P, adaption to the low or high temperature, resist to the plant diseases and insect pests, and the food of fish whose forage was grass.
鱼用优质高产牧草的种类繁多，为确定最佳的鱼草共生周年循环系统，本文选择几种冷季牧草和暖季牧草进行生长适应性与营养吸收研究，分析表明，多花黑麦草和扁穗牛鞭草是最佳的冷季牧草和暖季牧草，它们耐水性强，叶片中所含的粗蛋白、粗脂肪、粗纤维等化学成分高，植株的生物量也高，生物过滤养殖废水中的氮和磷效果好，而且可以适应外界环境的低温或高温，抵抗病虫侵害，同时为草食性鱼类喜欢食用。
