| 摘 要： | 随畜牧业发展,草田耕作制度在中国北方和南方发展迅速,我国南方逐步形成柱花草和一年生黑麦草为主的种植模式,我国北方呈现紫花苜蓿、黑麦草及沙打旺为主的种植模式。草田耕作具有提高土壤有机质、增加氮素供给、改善土壤物理特性、维持土壤养分平衡和防止土壤侵蚀等作用。草田耕作对合理利用土地资源和实现农牧业可持续发展具有重要意义。草田耕作使用地和养地结合,实现由传统粮食/经济作物二元结构向粮食/牧草/经济作物三元结构过渡,有利于提高光、热、水和土地资源利用,提高系统生产力,达到既提高粮食产量,又提供蛋白质饲料,同时改善生态环境。同时,两种作物或牧草间作或混作可产生互补作用。

| Abstract: | With the development of animal husbandry in recent years,the pasture-crop farming systems developed rapidly in China.Stylosanthes and annual ryegrass were the most important forages planting in South China,and alfalfa,ryegrass and milkvetch were the most important forages planting in North China.The pasture-crop farming systems were commonly recommended for improving soil organic and soil physical properties,and sustaining soil nitrogen content and keeping soil nutrients balance,and reducing soil and water erosion.The pasture-crop farming systems was one of the great approach to improve land use efficiency and good for the sustainable agricultural development and ecological environmental improvement in China.Utilization and enrichment of farmland could be combined in the pasture-crop farming systems with the conversing of the traditional agriculture planting of crops and economical to modern agriculture planting of crops,forage and economical crops.The pasture-crop farming system had a high productivity and a high utilization of light,energy,water and land resources.Also it could provide grain yields for human and protein forage for animals.And the systems of legums intercropped or mixed with crops or pastures had complementary effects on each others. |
