摘要
１９９３年５月至１９９５年１０月，在放牧和刈割处理方式下，对８种混播人工草地进行了生产性能研究，结果表明：（１）２种处理，豆科牧草和杂类草的含量均逐年增加，呈递增趋势；８种组合中，以鸭茅、草芦为主的组合较佳，能与白三叶的侵占力抗衡；（２）多组分的混播较简单混播为优，其中尤以草芦＋早熟禾＋白三叶的组合Ｇ为最佳，明显高于白三叶＋黑麦草的简单组合Ａ，表现在产量的稳定性和较强的抗逆性上；（３）放牧地干草产量明显低于刈割草地干草量。
During May, 1993 to October, 1995, eight types of mixed sowing artificial grasslands were studied in their production characteristics under the condition of grazing and cutting. The results showed that leguminous grasses and weeds increased year by year, the combination of Dictylis glemerate and Phalaris arundinacea was the best among them; more mixed sowing was better than simple one, the combination of P. arundinacea, Poa pratensis and Trifolium repens was the best among them, this combination was obviously better than the one of T. repens and Lolium perenne; its concret appearance was in the stability of production and adverse resistance; the hay yield in grazing was obviously lower than in cutting grassland, however, weeds in grazing was higher than in cutting.
