摘　　要：利用菌渣进行水稻生产小区试验,以探索其对水稻的增产效果及土壤肥力的影响。试验设无肥、化肥、低量菌渣、中低量菌渣、中量菌渣和高量菌渣6个处理。经过2年的小区试验表明,施用菌渣可有效增加水稻的分蘖数、有效穗数,提高稻谷产量;有效增加稻田土壤的碱解氮、速效钾和有机质含量。在水稻生产中,菌渣的直接施用量以7 180 kg/hm2较为合适。In a plot experiment, utilization of mushroom dregs for carrying on the rice production, which was to probe into the effect of rice yield and soil fertility. The experiment was designed for six treatments which were the no fertilizer control （ CK1 ）, a single application of chemical fertilizer （ CK2）, low quantity of mushroom dregs, medium-low quantity of mush- room dregs, medium quantity of mushroom dregs, and higher quantity of mushroom dregs. The result of two years＇ plot ex- periment showed that fertilizing mushroom dregs increased number of sub-lotus, effective panicles, improved rice yield and had a positive effect on the content of available nitrogen, available potassium and organic matter of paddy soil. It was concluded that the content of fertilizing mushroom dregs was 7 180 kg/hm2which was suitable relatively.
