摘要
研究表明：四季竹发笋期在4月下旬至10月下旬,6月发笋数最多,9月次之.6月出笋占总出笋棵数的35.56%,笋重量占总重的39.14%;9月出笋占总出笋棵数的20.78%,笋重量占总重的17.83%.四季竹幼竹高生长表现为生长初期和后期相对缓慢,整个生长期平均日生长量12.7 cm.生长高峰在笋出土后第15～35 d,平均日生长量19.2 cm,最大日生长量25.4 cm.四季竹日高生长量方程式为y=-3.785 5＋1.791 8 t-0.018 t^2-0.000 5 t^3.
The shooting period and height growth of Oligostachyum. Lubricum were observed, the results showed that the shooting period was from the last ten days of May to the last ten days of Oct. The shooting number was the most in june and reached another peak in September. 35.56% of the shoots presented themselves in June, and their weight took up 39.32%. 20.78% of the shoots presented themselves in September. The height growth climax appeared from the 15th to 35th day after emergence, with an average height growth of 19.2 cm · d^-1 and a maximum height growth of 25.4 cm · d^-1. The average height growth amount in the whole growth period was 12.7 cm · d^-1 . There were four phases of bamboo shoot growth. The equation of everyday height growth is y=--3. 7855＋1. 7918t-0. 018t^2-0. 000St^3.
