雅安市主要土壤固硅能力的研究
- Title:
- Research on the Silicon Fixation Ability of the Main Soil in Ya’an City
- Keywords:
- soil; silicon fixation ability; Ya’an City
- 分类号:
- S151.9;S153
- 摘要:
- 在实验室条件下，研究雅安市4 种主要土壤对水溶性硅的固定作用，结果表明：不同土壤类型的固硅能力的差异较为显著，振荡后立即测定和放置3 d后测定的结果均表现出同样的变化趋势，紫色土最高，黄壤最低，水稻土和黄棕壤居中。为该区域土壤的硅肥合理施用提供科学的依据，同时也为环境治理提供了有效途径。
- Abstract:
- Under the laboratory condition,the water-soluble silicon fixation was studied to the four kind of soils of Yaan city.The results indicated that,the different soils to silicon fixation ability were different between measure immediately and three days later,and tendency was consistency basically.Purple soil is the highest,the paddy soil and yellow brown earth are the middle,the yellow soil is the lowest.Thus it provided the certain scientific basis for the silicon fertilization employment reasonably,and it provided a way for the environment control simultaneously.
