不同处理葛萝槭生长特性与基质含水量关系研究

Research on Relationship between Different Treatments Growth Characteristic and Substrates Water Content of Acer grosseri Pax

在分析不同处理基质水分动态的基础上,探讨了7月份不同处理葛萝槭移植苗基质含水量的变化规律及其与生长特性的关系。结果表明,7月不同处理葛萝槭的基质含水量变化趋势不同,处理3和CK表现出了平缓的趋势,处理2表现趋势稍有波动但是幅度小,最终都表现为下降的趋势;不同处理葛萝槭(7月1日至7月31日)基质平均含水量大小排序为处理2>处理1>处理3>CK;综合分析叶片气孔导度、苗高、地径指标得出,除处理2外,不同处理的基质含水量与生长指标表现出相关性。

On the basis of analyzing the variation of substrates water content in different treatments, the relationship between the change rules of suhstrates water content and growth characteristic of transplanted Acer grosseri Pax in July were di- cussed, the results showed that the water content trend was different in different substrates of Acer grosseri Pax in July, The treatment 3 and the treatment 4 changed stably, the treatment 2 decreased fluctuately;The order of different substrates aver- age water content of Acer grosseri Pax was treatment 2 〉 treatment 1 〉 treatment 3 〉 treatment 4 ; The relationship between substrates water content and living parameters was significant in different treatments,except treatment 2.
