摘　　要：以山东省齐河县低肥力潮土为供试土壤 ,15年盆栽土培定位试验结果表明 ,长期秸秆还田并配施适量的化肥 ,是培肥地力 ,提高产量的有效措施之一。在秸秆还田量分别为 2 2 5 0、45 0 0、675 0kghm- 2 范围内 ,土壤有机质积累量 ,速效氮磷钾的生物有效性 ,脲酶活性强度等指标与秸秆还田量呈极显著正相关 ,并与气候、作物生长季节。Experiment was carried out with flouvo-aguic soils of low fertility coming from Qihe,Shandong Province The results of 15 years application showed that match ing use of straw and chemical fertilizer is an effective measure to increase yie ld and improve soil fertility As straw application rate at the range of 2 25 0, 4 500,6 750 kg hm -2 , the accumulation of O M ,available nutrient an d activity of urease have markedly positive correlation to amount of straw and a re effected by climate,growing season,soil texture et al
