摘要
为制定促进古松柏良好生长及复壮措施提供科学依据,对曲水园古白皮松、古桧柏进行了土壤质量调查与分析,结果表明:古白皮松、古桧柏生长环境的土壤pH值较高、而土壤的EC值、有机质和速效氮的含量偏低,由此会对古白皮松、古桧柏的生长造成不利影响;经测试,古白皮松和古桧柏土壤中的有效磷含量达丰富水平,土壤中的微生物含量,古白皮松比古桧柏要高。对存在的问题提出了相应的改良措施。
The qualities of soil around old trees - Pinus bungeana and Sabina chinensis in Qushui Garden were investigated and analyzed. The results shows that pH value of soil is higher, but EC value and eontent of organic substance and nitrogen are quite lower, which would effect growth of these old tress; there are higher content of effective apatite in the soil around Pinus bungeana and Sabina ehinensis, microbes in the soil at Pinus bungeana are richer than those at Sabina chinensis. The paper gives relevant measures for improving soil.
