中国沙棘人工林适宜平茬高度的探讨
|
摘要
采用单因素回归设计,在系统分析萌蘖更新效果对平茬高度响应规律的基础上,建立了萌蘖再生率与平茬高度的回归方程,据此确定适宜的平茬高度。结果表明:随着平茬高度的增大,伐桩萌蘖存活率、根系萌蘖数量以及萌蘖生长、克隆扩散、生物量积累能力先升后降(或先升后稳),平茬高度为10 cm时最大。再生率与平茬高度的关系可用二次抛物线拟合,根据回归方程求导,最有利于中国沙棘人工林迅速恢复的平茬高度为10.0～12.0 cm,结果一致。
Based on the single factor regression design, and systematic analysis of the effects of germination update on the height response of the scorpion, the regression equation of germination rate and the height of the raft was established, and the appropriate ridge height was determined accordingly. The results show that with the increase of the height of the sorghum, survival rate of germination, number of root germination and growth of germination, clonal diffusion and biomass accumulation increase first. Maximum when the height of the flat is 10 cm.The relationship between the regeneration rate and the height of the flattening can be fitted by quadratic parabola.According to the regression equation, the height of the flattened height of Hippophea Rhmnoides ssp. sinensis plantation is 10.0-12.0 cm. The results are consistent.
