Abstract

团聚体稳定性是土壤质量的重要指标。鉴于当前团聚体稳定性难以定量的研究现状,本文提出一个可定量
评估土壤团聚体稳定性的超声能量法,并与传统 Yoder湿筛法对比分析了稳定性土样(浙江潮土、重庆黄壤土、江西
红壤)和弱稳定性土样(河北壤土和黑龙江暗棕壤)五种典型土壤的5~3mm 粒级团聚体的平均重量直径( MWD
)和
团聚体粒径分布( ASD )。结果表明:(
1 )测试土样的稳定性为潮土 > 红壤 > 黄壤土  暗棕壤 > 壤土;( 2 )超声能量法
分散强度大,分散效率高,更适用于稳定性土样的评估,对于弱稳定性土样的评估则不如传统 Yoder湿筛法。因此,
评估土壤团聚体稳定性时可以选择合适的测量方法以提高分辨精度,即强稳定性土壤对比分析应选用超声能量法,
而弱稳定性土壤对比分析则可以用 Yoder湿筛法。

Other Abstract

: Aggregate stability is an important index of soil quality , but hard to be quantified.Here an ultra -
sonic energy method was developed to quantify
soil aggregate stability , and its practicability was tested by
comparing with Yoder method in terms of mean weight diameter
( MWD ) and aggregate size distribution
( ASD ) of two groups of soils , 3stable soils ( Fluvo
- aquic soil from Zhejiang Province , Yellow loam from
Chongqing City , Red soil from Jiangxi
) and 2weak soils ( Loam from Hebei Province , Dark brown soil from
Shangdong Province ) .The results show that the stability
indicated by MWD decreases in the order
: Fluvo

aquic soil>Red soil>Yellow loamDark Brown soil>Loam ; the ultrasonic dispersion cam break soil aggre -
gate efficiently due to its strong dispersing power
, and thus this method prefers to strong soil than Yoder
method , but this method seems not to be suitable to assess the aggregate stability of weak soil compared with
Yoder method.Therefore , aproper method assessing soil aggregate stability can be chosen through the rule :
ultrasonic energy method for stable soil
, Yoder method for weak soil.
