摘要

采用盆栽试验方法

以不施赤泥为对照

分析不同赤泥施用量对Cd污染稻田水稻产量和土壤生物性状的影响。结果表明

施适宜用量赤泥能提高水稻有效穗和促进水稻生长

实现水稻增产

与不施赤泥处理相比

RM-2处理(0.5%赤泥)的水稻株高、有效穗、结实率和水稻产量分别提高了3.40%

4.20%

3.87%和6.86%。从分蘖期到成熟期

施用赤泥处理各生育期的水稻土微生物量碳、氮明显高于对照RM-0处理的。其中

RM-2处理(0.5%赤泥)各时期水稻土微生物量C(SMBC)、微生物量N(SMBN)都明显高于RM-0处理的(P<0.01)。施用赤泥处理的稻田土壤细菌、真菌和放线菌数量多数情况下高于对照RM-0处理的。RM-2处理土壤细菌、真菌和放线菌菌群数量多数情况下高于其他处理的。RM-2处理土壤脲酶活性、酸性磷酸酶活性和过氧化氢酶活性均为最高

分别比RM-0处理的提高了10.5%

32.4%和15.9%

且两处理间差异均达到显著水平(P<0.05)。与RM-0处理相比

施用赤泥各处理pH和阳离子交换量均有不同程度增加

但有机质的变化不明显。0.5%(W/W)的赤泥施用量较其他施用量有利于改善Cd污染水稻土生物性状

提高...

Abstract

A pot experiment was conducted to study the effect of application of different amount of red mud on rice yield and the soil biological properties in Cd-polluted paddy soil

with no red mud application as the control(RM-0).The results indicated that appropriate application of red mud could apparently promote rice growth and increase effective panicles and rice yield.With no red mud application as the control(RM-0)

plant height

effective panicles

seed setting rate and rice yield in RM-2 treatment(0.5% red mud)...
