摘要
通过玉米盆栽试验,研究了不同水分条件下菌肥对土壤碱解氮的影响。结果表明:土壤含水量范围在9％-20％时,施用生物菌肥对提高土壤碱解氮有显著效果;不同的水分条件下菌肥发挥的肥效不同,土壤含水量为13％-16％时,菌肥对土壤碱解氮的影响最大,且玉米的生长状况良好。
Potting experiments were carried out to study the effects of bacterial manure on Soil Base dissolving N under different conditions of soil moisture content. The results showed that Soil Base dissolving N increased after application of bacterial manure when soil moisture content was 9%-20%. But under different conditions of soil moisture content , the bacterial manure＇ s efficiencies were different. About 13%-16% of soil moisture contents the bacterial manure had the best effects on Soil Base dissolving N , and the corns grew well.
