摘　　要：本研究测定了平菇菌糠腐熟后的氮、磷、钾含量,提取了腐熟菌糠的水溶性和醇溶性物质以及腐殖质。用这些提取物对莴笋、玉米、茄子和黄瓜进行了苗期叶面喷施正交试验,其植物促长结果为:平菇腐熟菌糠含全氮0.21%、全磷0.95%(以P2O5计)、全钾0.62%(以K2O计);腐熟菌糠的水提物、乙醇提取物和腐殖质提取率分别为4.05%、0.31%和23.31%;作物苗期最大叶片的长度增量对喷施处理反应敏感,可在较短时间对不同活性物的促长效果做出评价;腐殖质的促长作用最大,对叶片长度的促进效果是商品叶面肥诺贝宁的1.48倍,是乙醇提取物的1.34倍,差异显著。水提物的作用略差于乙醇提取物,略好于诺贝宁,但差异都未达显著水平。In the study,the contents of three major nutrient elements in decomposed SMS from Pleurotus mycelium production were determined.The aqueous extract （AE）,ethanolic extract（EE） and humus were extracted from this kind SMS,and their growth-promoting effects on seedlings of lettuce,maize,eggplant and cucumber were evaluated by foliage spray in various concentrations in an orthogonal experiment.The main results were as follows：the total contents of nitrogen,phosphorus and potassium were 0.21%,0.95%（P2O5 %） and 0.62%（K2O %） respectively.The extraction rates of AE,EE and humus were 4.05%,0.31% and 23.31%respectively.The increment of maximum leaf length was sensitive to the stimulation of the extracts and could be taken as a simple index for evaluating growth-promoting effects of different extracts in a short experiment period.The growth-promoting effect of humus was 1.48 times that of Nuobeining,a commercial foliar fertilizer.The effect of AE was slightly better than that of Nuobeining and inferior slightly than that of EE,but the differences among them were not significant.
