早竹1年生竹鞭上的侧芽即可萌发,翌年无芽节数占总节数的47.75％,5年之内达89.87％,萌发能力特别强。早竹3月中旬开始出笋,5月上旬结束,高峰期2.0天左右,占出笋总数的75.2～80.7％。早竹高度相对生长率与时间的关系符合Logistic曲线方程。温度对高生长有极显著的影响。留养新竹时期推迟,完成高生长的时间缩短,新竹平均胸围和平均高度均下降。
One year old bamboo shoots on the side of the bud can germinate, the next year without the number of buds accounted for 47.75% of the total number of sections, up to 89.87% within 5 years, particularly strong germination. Early bamboo shoots began to shoot in mid-March and ended in early May with a peak period of about 2.0 days, accounting for 75.2 to 80.7% of the total number of shoots. The relationship between the relative growth rate of early bamboo and time accords with the Logistic curve equation. Temperature has a very significant effect on high growth. Hindu stay time to postpone the completion of high growth time shortened, Hsinchu average chest circumference and the average height decreased.
