木薯种茎长度与节点数对其农艺性状的影响
|
摘要
为了探究不同的种植种茎长度和节点数对木薯农艺性状的影响,以华南9号木薯为材料,对木薯种茎的长度(L)和节点数(S)分别设置3个处理(L1、L2、L3和S1、S2、S3)共计9个组合,按照相同管理方式种植。结果表明:木薯种茎的节点数与株高、茎粗、第一分支高度、茎秆叶鲜重、鲜薯重和鲜薯数均无显著相关性,种茎的长度与茎秆叶鲜重和第一分支高度显著相关,增大木薯种茎长度可以提高鲜薯重、茎秆叶鲜重及第一分支高度,试验中处理L3S3鲜薯重比对照(CK)高9.8%,茎秆叶鲜重比对照高19.1%,第一分支高度比对照高10.5%。
Seed stems of cassava cultivar SC9 were collected and 3 treatments were arranged each for stem length(L1, L2 and L3) and for number of stem nodes(S1, S2 and S3), totaling 9 combinations. The seed stems were planted and cultivated in the same pattern to explore the effect of stem length and number of nodes on the agronomic traits of cassava. The results showed that the number of nodes was not significantly correlated with the plant height, the stem diameter, the first branch height, the weight of the stalks and leaves, the weight of fresh cassava roots and the number of cassava, and that the seed stem length was significantly correlated with the weight of the stalks and leaves and the first branch height. The high stem length could increase the weight of fresh cassava roots, the weight of the stalks and leaves and the first branch height. For the treatment L3 S3 the fresh cassava weight was 9.8% higher than that of the control, the weight of the stalks and leaves was 19.1% higher than that of the control, and the first branch height was 10.5% higher than that of the control.
