摘要
对豫南地区引种的金镶玉竹的发笋节律、退笋及幼竹高生长规律进行连续3 a的观测研究,结果表明:豫南地区金镶玉竹的笋期从3月下旬—4月下旬,历时30 d;退笋率为26.56%,退笋高度主要集中在40 cm以下;幼竹的高生长规律符合"S"型生长曲线,Logistic方程为H=237.9791+e4.280-0.401t。
The Shooting rhythm , degeneration and Height growth of young bamboo of Phyllostachys aureosulcata f.spectabilis Intro-duced into South area of Henan Province were observed and analyzed ,The results shows that the shooting period of Phyllostachys au-reosulcata f.spectabilis is from late March to late April,take 30 days,Degenerated shoot rate is 26.56%,In which degraded shoot height often occurred on the following 40 cm,The logistic curve model of height growth was H= 237.9791＋e4.280-0.401t.
