摘要
本研究通过25棵样笋对冬笋——春笋高生长的测定,经数学分析得到以下两个关系式: H=1.8H_mt^(0.24-0.004 1T)(?) (1) ⊿H=(0.021T-0.180)H^(0.873) (2)(1)式表示竹笋高度(H)与时间(t)的关系,参数A=1.08H_m(H_m是出土时竹笋高度),B=0.246-0.0041T_(10).土壤积温(T_(10)对竹笋高生长有明显的效应,它通过影响上述参数B控制着冬笋——春笋的高生长,随着积温的递增,竹笋增高加快,出土时间提前。(2)式表示竹笋高生长量(⊿H)与竹笋高度(H)的关系,参数A=(0.021T-0.180),B=0.873.土壤日均温度(T)与高生长量也有紧密关系。随着土壤温度的上升,高生长量以0.021H^(0.873)的递增率直线增加。对此,笔者提出了竹笋促成栽培——土壤增温技术的建议。
Based on the data with 25 bamboo shoot samples, two equations
were obtained as a result of regression analysis:
△H = (0. 021 T- 0. 180)H0.873
where H is the elongation of bamboo shoot, Hm, the height of shoot at the time of emergence of shoot, t, time, T10, accumulated temperature in the soil, AH, the elongation increment of bamboo shoot, and T, daily mean temperature in the soil. For this, the techniques of raising soil temperature which can make bamboo shoot emerge about one month earlier are given in this paper.
