摘要 | 采用二因素三水平(生物炭用量分别为干土重的0 , 2%和4% ,聚丙烯酰胺用量分别为干土重的0 , 0.02‰和
0.04‰ )完全试验方案设计,研究了两种土壤结构调理剂生物炭和聚丙烯酰胺( PAM )共施对黄绵土水分入渗和土壤
蒸发的影响。结果表明:( 1 )生物炭施用后对 Philip 模型的稳渗率(
A
)和
Horton 模型的衰减指数(
β )有显著影响,
2%
生物炭添加对 A 和 β 影响不大,但 4% 生物炭添加显著降低 A ,显著增加了 β ;施用 PAM 对 Kostiakov 模型的参数 K ,
Philip 模型的吸渗率(
S )和 Horton模型中的稳定入渗率( i f )与初始入渗率( i 0 )有显著影响, 0.02‰PAM 添加对这些
参数无显著影响,但0.04‰PAM 添加显著降低 K , S , i
f 和 i 0 。生物炭和PAM 共施对3种入渗模型的大多数参数存
在显著交互作用。所有处理中,以 2% 生物炭 +0.02‰PAM 增加入渗的效果为最好;( 2 )生物炭、 PAM 及二者交互作
用对蒸发速率和累积蒸发量影响均不显著,表明生物炭和 PAM 单施或共施对黄绵土蒸发影响不大。 |
其他摘要 | Using two - factor and three - level ( Biochar was applied at rates of 0 , 2%and 4%of dry soil weight ,
and polyacrylamide was used at the rates of 0 , 0.02‰and 0.04‰of dry soil weight ) complete experimental
design , we examined the effects of two soil conditioners , biochar and polyacrylamide ( PAM ), on soil infil -
tration and evaporation in loessial soil.The results indicated that :( 1 ) the application of biochar had signifi -
cant effects on steady infiltration rate (
A , Philip model ) and attenuation exponent (
β , Horton model
), the
application of 2% of biochar had no significant effects on these parameters compared to the contrast , while
the application of 4%of biochar had significantly decreased A , but had increased β .The application of PAM
had significant effects on K
( Kostiakov model ), sorptivity (
S , Philip model ), final and initial infiltration
rates ( i f and i 0 respectively , Horton model ); application of 0.02‰ of PAM had no effects on these parame -
ters while application of 0.04‰of PAM siginificantly decreased these parameters ; the significant interaction
of biochar and PAM for most infiltration parameters was found.The mixed application of 2%of biochar and
0.02‰ of PAM was the best in improving the infiltration rates in all treatments ;(
2 ) there were no signifi -
cant effects of biochar , PAM and their interaction on the evaporation rate and cumulative evaporation , indi -
cating that single or mixed use of biochar and PAM had no effects on soil evaporation in loessial soil. |
