- 摘要:
- 以上海海湾国家森林公园梅花为试材,通过不完全随机取样,测定土壤的pH和植株生长发育指标,采用统计分析的方法,研究了高土壤pH对梅花生长发育的影响,以期找到耐碱土的梅花品种,并为梅花耐盐碱机理的研究提供参考。结果表明:上海海湾国家森林公园土壤pH在8~9,梅花基本正常生长。梅花具有较强的耐碱土能力,高pH下,梅花生长发育情况有一定变化。一年生枝的长度与土壤pH具有相关性,随pH增加梅花一年生枝的长度有降低的趋势。高pH下,梅花着花量减少,花径有变小的趋势。
- Abstract:
- In order to find the alkali-resisting cultivars and provide reference for the research on alkali-tolerant mechanism of Prunus mume,Prunus mume response to high pH was studied in Shanghai Haiwan National Forest Park by not entirely random sampling and statistical methods.The soil pH and the growth and development of plants were measured.The results showed that the range of soil pH was 8-9 in Shanghai Haiwan National Forest Prk,in which Prunus mume grew well.In the study,it illustrated that Prunus mume had strong alkali-resisting abilities.The growth and development of Prunus mume had some changes in high pH.The length of annual branches were relevant with soil pH.With pH increased,the length of annual branches decreased.Similarly,flower diameter became smaller and blossom quantity decreased in high soil pH.
