摘　　要：通过营养繁殖在黄河滩栽植王草，研究该草的生产性能和越冬性能，探索在温带黄河滩区种植的可能性和必要性，为丰富河南黄河滩区优质饲草资源，发展现代草食畜牧业提供饲料基础。结果表明，王草在河南适合在4月10日到4月20日栽植，生长期为6个月，生长最快在6～7月份，植株全年都处于营养生长期，不抽穗不扬花，全年茎叶比和鲜干比分别平均为0．77和7．01，鲜草产量为323．23t／hm2。在大田条件下，可通过覆盖稻草和外加塑料薄膜来提高王草的越冬率，确保第2年的繁殖成活。该研究结果有利于解决王草在黄河滩区的安全生产问题，降低生产成本，提高种植效益。Based on the soil and climate conditions on yellow river beach, king grass from sub-tropic temperature region was planted on yellow river beach in order to study its production performance and win- tering habit. The present study aimed to analyze the possibilities and necessaries of planting king grass in temperature region to enrich the forage resources in Henan province to facilitate the development of local modern herbivore animal husbandry. The study result showed that the proper time for planting king grass was between 10th of April and 20th of April, and the growing period lasted for 6 months; king grass would stay in vegetation period without experiencing flowering stage on yellow river beach. Stem to leaf ratio and fresh to dry ratio were 0. 77 and 7.01 respectively, and total biomass was 323.23 t ~ hm-2. Wintering plants could be well protected from winter harsh environment if covered with straw and plastic film togeth- er. This research results help to find solutions to the wintering problem of king grass, reduce production cost and improve planting profit.
