摘要
通过模拟实际植树造林操作方法,进行了不同浓度梯度多功能复合材料对土壤物理性质影响的研究。结果表明:多功能复合材料可以降低土壤的pH值和土壤容重,提高土壤总孔隙度,提高土壤阳离子交换容量。随着施用多功能复合材料浓度的增大,土壤中>0.25mm的团聚体含量增加,当保水剂用量为50g时,>0.25mm的团聚体含量比对照提高了约8.91%￣12.50%。
s: In this paper, the effects of multifunctional composite on soil physical properties were investigated through simulated the tree planting method as much as possible. The results showed that multifunctional composite can decreased soil pH and bulk density, increased the contents of total porosity, and improved soil cation exchange capacity. Soil >0.25mm aggregates were increased with increasing of concentration of multifunction composite. When using super absorbent with the dose of 50g, the >0.25mm aggregates proportion was increased in 8.91%~12.50% compared with control.
