摘要
[目的]探明pH对松柳芽苗菜生长的影响规律，为松柳芽苗菜的培育提供改进建议。[方法]采用20℃育苗盘恒温水培栽植方法，通过改变不同培养液pH，检测相应松柳苗出芽率及成熟期松柳的整株重量和根重，分析其对酸碱的耐受性。[结果]强酸和强碱条件均会对松柳的生长产生较强的抑制作用，而在弱酸和弱碱环境下，松柳有较强的耐受性。[结论]在松柳发芽的早期阶段，弱酸条件可提高松柳的出芽率；后期生长阶段，弱碱条件可提高松柳的生长速度。
Abstract
Objective] The aim was to explore influence of pH to growth of pine willow sprout, to provide improvement suggestions for culti-vation of pine willow sprout.[ Method] The germination rate of pine willow sprout, whole plant weight and root weight of pine willow in mature period was detected, resistance to acid and alkali conditions were analyzed under the condition of 20℃ water by adjusting pH value.[ Result] The results showed that both strong acid and strong alkali can induce strong inhibition to the growth of pine willow, while the pine willow has stronger resistance to acid and alkali conditions.[ Conclusion] In the earlier germination stage, the weak acid conditions can increase the rate of pine willow budding; In the later growth stage, the weak alkali conditions can speed up the growth of pine willow sprout.
