摘  要:
在对桂牧一号杂交象草繁殖特性了解的基础上,采用种茎半掩埋法越冬和覆盖种蔸留地越冬两种方法使其安全越冬,其中覆盖种蔸留地越冬的方法又采用种蔸覆盖牛粪、覆盖薄膜、覆盖火土灰、覆盖稻草、覆盖黄土等5种不同的处理方式。结果表明:种茎半掩埋法越冬种茎的越冬率为75%,每667m2年产量为18589.2kg,;种蔸留地越冬中覆盖牛粪、覆盖薄膜、覆盖火土灰、覆盖稻草和覆盖黄土的越冬率分别为:80%、100%、80%、70%、75%,比对照区分别高出30%、50%、30%、20%、25%,产量分别为:19451.2kg、19018.5kg、18936.4kg、18106.6kg、17982.9kg,比对照区分别高出19.9%、17.2%、16.7%、11.6%、10.9%。另外对每个处理作出了评价。

摘  要:
Based on the knowledge of reproductive characteristics of Guimu-1 Hybrid Pennisetum urpureum,we can adopt the methods of burying the seed stem half and covering the live seed root to make them live through the winter safely. The methods of covering the live seed root included five treatment ways: using cow dung,membrane,ash soil,rice straw and loess independently to cover the seed root. The results showed that the over-wintering rate of seed stem buried half was 75%,and the output per acre was 18 589.2 kg. While using the method of covering the live seed root,the over-wintering rate of seed stem covered by cow dung,membrane,ash soil,rice straw and loess was 80%,100%,80%,70%,75% respectively which was 30%,50%,30%,20%,25% higher than the control plot. Their output per acre was 19451.2 kg,19018.5 kg,18 936.4 kg,18 106.6 kg,17 982.9 kg respectively which was 19.9%、17.2%、16.7%、11.6%、10.9% higher than the control plot. In addition,each treatment was evaluated.
