摘要
采取随机区组试验,研究了宁夏盐池地区几种种植模式对中科2号羊草成苗的影响。研究结果表明,几种种植方式均能对羊草的成苗产生正向影响,其总体表现依次为直接覆黑膜(揭膜)、起垄覆白膜、起垄不覆膜、覆草、点播覆黑膜(不揭膜)、直接覆白膜(揭膜)、空白条播、点播覆白膜(不揭膜),其中覆黑膜、覆草和起垄更有利于羊草的成苗。因此,宁夏盐池地区人工种植中科2号牧草,应采用覆膜、起垄、覆草等种植方式。出苗后,精细管理,保证牧草成苗。
In this study, the effects of several planting modes on seedling of Leymus chinensis Zhongke No. 2 at Ningxia Yanchi area were analyzed. The results showed that the all planting modes had positive effect on seed germination and seedling of Leymus chinensis. The effect was sequenced by Direct coated black film （Film Uncovering） , Ridge covering tunica albuginea, Ridging Mulched, Straw mulching, VOD cover black membrane （don＇t open the film）, Direct over the tunica albuginea （uncovering film）, blank drilling, VOD cover tunical albuginea （don＇t open the film）. And the modes of covering black film, straw mulching and furrow sowing showed more benefit to Leymus chinensis seedling. It indicated that to ensure the ensure the Leymus chinensis seedling at Ningxia Yanchi area the planting modes should be mulching and furrow sowing, covering grass and with fine management.
