摘要
以新品种“８６０２”为试材的研究表明，双季茭白的分蘖与叶片的抽生存在同伸关系，株高生长前期呈“Ｌｏｇｉｓｔｉｃ”生长曲线，不同时期发生的分蘖、孕茭在时间和肉质茎大小上存在差异。定植４～５个分蘖的茭苗，分蘖主要在６月中旬以前出现，此时的分蘖孕茭率最高。
In this paper, we studied systematically dynamic of tiller, occuring of leaves and development of plant height on double cropping fewflower wildrice. We studied on the relation of the tiller occuring in different phase and booting flesh stem. The results showed that occuring of tiller's leave kept same pace. The development of plant height showed “Logistic” curve at the beginning phase. The tiller occured in different phase result in the different time of booting and size of flesh stem.
