摘要
以当地栽培的主要品种作对照,研究了引进的4个木薯新品种华南5号(SC5)、华南6号(SC6)、华南7号(SC7)、华南8号(SC8)的适应性。结果表明:在试种区,4个木薯新品种均表现出较强的抗病能力;华南5号和华南7号出现一定的倒伏情况,说明这两个品种抗风、耐倒伏能力差;华南7号、华南5号、华南8号和华南6号的产量均比对照品种明显提高,华南7号的产量与对照品种产量成差异显著;华南5号干物质含量比对照品种干物质含量高且差异显著,华南6号和华南8号干物质含量与对照品种相当,华南7号干物质含量比对照品种干物质含量低且差异显著;华南8号和华南5号淀粉含量与对照品种相当,华南6号和华南7号淀粉含量比对照品种淀粉含量低且差异显著。
The experiment was carried out on 4 newly introduced cassava cultivars to study their adaptability. The results showed that all the 4 newly introduced varieties display the strong disease-resistant ability. SC5 and SC7 appeared a certain lodging circumstance which explained these two varieties anti-lodging abilities were weak. The yields of SC7, SC5, SC8 and SC6 were higher than the CK. The yield between SC7 and the CK appeared significant difference. The dry yield of SC5 was higher than the CK and appeared significant difference. The dry yield of SC7 was lower than the CK and appeared significant difference. The dry yield of other were equal to the CK. The starch content of the CK was higher than all the 4 new introduced varieties.
