以白皮菊芋为试材,通过对现蕾期菊芋去除1/4花、1/3花、1/2花、全部去除和不去花等5个处理,测定叶片、小花、分枝和块茎数量等相关指标,探讨了去花对菊芋数量学性状的影响规律,为提高菊芋块茎生物产量提供理论依据。结果表明:去花1/3、1/2和全株去花提高了单株菊芋块茎数量,降低单株块茎质量,1/4去花对菊芋单株块茎数量和单个块茎质量影响不显著;去花处理降低了二级分枝和一级分枝的数量;去花处理增加了单株叶片的数量和单片叶片的质量;随着去花数量的增加,单株小花数量呈现“降-升-降”的变化规律,单个小花质量呈现“降-升”的变化趋势。
Taking white pea taro as test material, 5 treatments of removing 1/4 flower, 1/3 flower, 1/2 flower, all removing and not removing flower were performed on Jerusalem artichoke in budding stage. Leaf, floret, branch and tuber Quantity and other related indicators, to explore the flowering of Jerusalem artichoke quantitative properties of the law, to provide a theoretical basis for increasing tuber biological yield. The results showed that the numbers of tuber of single Jerusalem artichoke increased and the tuber quality of single tuber reduced. The effect of 1/4 decolonization on tuber number per tuber and individual tuber quality was not significant. The flowering reduced the number of secondary branches and primary branches. The flowering increased the number of leaves per plant and the quality of single leaves. With the increase of flowering number, - L - L “, the quality of a single floret shows the trend of” L - L ".
