冬小麦与苏丹草不同种植方式下产量效益比较研究

A Comparative Study of Winter Wheat and Sudan Grass of Production Efficiency in Planting Different Ways

通过在新疆奇台县和吉木莎尔县进行冬小麦单播、苏丹草单播、冬小麦与苏丹草套种、冬小麦复播玉米、复播豌豆以及大麦与苏丹草混播试验示范,冬小麦(Triticum aestivum)、大麦(Hordeum vulgare)与苏丹草(Sorghum sudanense)套种、混播,不影响冬小麦、大麦的产量,苏丹草干草产量可达到15000kg/ha。冬小麦套种苏丹草效益明显优于其它播种方式,在昌吉州乃至新疆大部分地区都可推广种植。冬小麦套种苏丹草比冬小麦复播玉米、复播豌豆效益明显。套播苏丹草较复播豌豆效益增加31.3%,套播苏丹草较复播玉米效益增加16.1%,大麦、苏丹草混播较单播大麦效益增加61.2%。冬小麦套种苏丹草技术解决了种粮与种草之间争地的矛盾,为促进畜牧业快速健康发展探索出了新的途径。

Adopted in Qitai county and Jimsar county winter wheat and sudangrass sowing, sudangrass and winter wheat interplanting, winter wheat multiple-sowing corn and peas, barley mixed sowing with sudangrass test model, winter wheat （Triticum aestivum）, barley （Hordeum vulgare） and sudangrass （Sorghum sudanense） interplanting and mixed sowing, do not affect winter wheat and barley production, sudangrass hay production could reach 15000 kg/ha. Effectiveness of interplanting sudangrass and winter wheat is superior to other planting, in Changji of Xinjiang, and in most parts of the state can promote cultivation. Interplanting winter wheat and sudangrass than sowing of winter wheat and corn, peas multiple benefits obvious. Interplanting winter and su wheat and sudangrass than the multiple pea effective increase 31.3 dangrass than multiple corn effective increase 16.1 percent, barley percent, interplanting winter wheat and sudangrass unicast mixed than sowing barley increase effective 61.2 percent. Winter wheat and sudangrass of interplanting technology to solve a conflicts with the grain-growing and grass for land, it is a exploring new way for rapid and healthy development of animal husbandry
