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。。。
