为开发利用野生牧草资源及探索其建植不同利用方式的人工草地途径,在天山北坡低山带乌鲁木齐段的南山试验种羊场对野生牧草引种驯化的同时进行了混播组合试验。羊茅与华北岩黄芪混播,第三年干草产量2970kg/ha,比单播提高3.7%和62.3%,增产效果明显。用红豆草与两种禾草混播,第三年干草分别为7260kg/ha和7425kg/ha,其中红豆草与新麦草混播比单播分别提高5.67%和16.34%。中间偃麦草与黄花苜蓿混播以后3年的平均产量为4875kg/ha。本文重点介绍野生牧草混播试验方法,混播以后的牧草产量、牧草的营养成分等内容。
In order to exploit the resources of wild forages and explore the artificial grassland ways of establishing their different utilization ways, a mixed-sowing combination experiment was carried out on the introduction and domestication of wild forages in the Nanshan experimental breeding farm in the Urumqi section of the northern slope of the Tianshan Mountains. Festuca and North China rock Astragalus mixed, the third year hay output 2970kg / ha, increased by 3.7% and 62.3% than unicast, yield increase effect is obvious. In the third year, the hay was 7260kg / ha and 7425kg / ha, respectively. The mixed sowing date with new grass increased 5.67% and 16.34% respectively. The average yield of 3-year mixed media was 4875 kg ha-1 after mixed planting of Elytrigia intermedium and Medicago falcata. This article focuses on the wild forage mixed-sowing test methods, mixed pasture yield, forage nutrients and so on.
