天目早竹梅雨季节造林效果及其出笋成竹规律研究

经对天目早竹梅雨季节造林试验和笋期观测３年调查资料统计分析，结果表明：梅雨季节移栽天目早竹，成活率高，发笋成竹快，３年即可满园。天目早竹自然出笋期在３月２６日～４月１２日，分为初期、盛期、后期，各期成竹率和早期退笋率以及新竹质量有明显差异；母竹系统质量和距母竹远近对新造竹林的出笋成竹能力有一定影响；笋竹高生长服从Ｓ型曲线增长规律。

Effect of Transplanting Phyllostachys tianmuensis in the Rainy Season on SurvivalRate and Rapid Grove Establishment

A bamboo grove establishment trial was cond ucted with Phyllostachys tianmuen-sis,and an ensuing observational study lasting 3 years made. Restilts showed that transplantingP. tianmuensis in the rainy season not only made possible a high rate of survival of the parentstock,but also attained a dense coverage of yoting bamboos in as short as 3 years. Generally,shoot sprouting with P,tianmuensis occurs from March 26 through April 12,which can be divid-ed into the early phflse,the full phase,and the late phase in terms of shoot sprout.The culms set varied with the phase of shoot sprout in,quality,just as the capacity of shoot production and culmset of the new grove is related to the quality of the parent stock.Height growth of both the shootand the culm comforms to the S curve qattern.
