摘    要:不同有机物料稻草,猪粪,锯木屑成分不同,入土转化过程不同,对连作土壤pH,EC值产生不同的影响。通过培养实验表明猪粪有降低土壤pH,提高土壤EC值的作用,稻草能提高土壤的pH,EC值,而锯木屑对土壤pH,EC值影响不大。稻草施入土壤后增加了细菌,放线菌数和真菌数。锯木屑能增加土壤细菌数,真菌数,而放线菌数减少。猪粪使土壤细菌数,放线菌数大幅度增加,而真菌数减少。

关 键 词:有机物料  土壤微生物  土壤pH值  土壤EC值  连作土壤

Abstract:Different organic materials such as rice straw, wood dust and pigfeces have different ingredients, which converse in different ways and exert different acts on the pH and EC value of continuous cropping soil.The study shows that pigfeces can lower soil pH and increase the soil EC value; Rice straw can enhance the soil pH and EC; Wood dust, however, have little effect on soil pH and EC value. It is also found that applying rice straw in the soil increases the amount of bacteria, actinernyces and epidhyte; Wood dust can add the amount of bacteria and epidhyte, but decrease the amount of actinemyces in the soil; and the amount of bacteria and actinemyces in pigfeces treatment is more than the controlled one, but the epidhyte is less.
Keywords:organic materials  pH  EC  microbe
