摘要
通过室内模拟试验,研究了3种植烟土壤饼肥矿化过程中土壤酶活性与理化指标的变化。结果表明:饼肥能有效的调节土壤的pH值,增加土壤中有机质、水解氮、速效磷的含量;红壤中速效磷释放效率最高,紫色土脲酶活性最强,水解氮含量最高,蔗糖酶在土壤中活性较稳定;不同土壤饼肥肥效释放速率为紫色土>水稻土>红壤,紫色土种植烤烟宜施未发酵或者发酵时间较短的饼肥,红壤和水稻土应使用腐熟完全的饼肥。
Changes of enzyme activities and physical and chemical indexes from three tobacco growing soils were studied by indoor experiment using cake fertilizers＇ mineralization.Results showed that cake manure can effectively adjust soil pH value and increase amount of organics,hydrolyzable nitrogen,and available P in the soil.Red soil had the highest release rate of P Cake manure fertilizer efficiency release rate in different soils were paddy soilpurple soilred soil.Unfermented or short-term fermented cake manure should be used in purple soil,while completely fermented cake manure should be used in red soil.
