摘　　要：选择腐熟鸡粪作为基肥,设置3种用量,即2.5、5.0、7.5 kg/m2进行构树(Broussonetia papyrifera)播种育苗试验,研究其出苗率、地径、苗高、叶面积、生物量、根系等情况。结果表明,腐熟鸡粪用量2.5 kg/m2的出苗率为13%、5.0 kg/m2的出苗率为17%、7.5 kg/m2的出苗率为25%;但地径、苗高、叶面积、生物量、根系各项指标以腐熟鸡粪用量5.0 kg/m2的最好,2.5 kg/m2的效果次之,各项指标所反映情况一致,腐熟鸡粪5.0 kg/m2用量最适合构树播种育苗。Using rotten chicken manure as basic fertilizer, three kinds of dosages were set up, inoluding 2.5,5.0 and 7.5 kg/m^2 for planting seedling of Broussonetia papyrifera to study emergence rate, ground diameter, seedling height, leaf area, biomass and root. The results showed that the emergence rate of 2.5 kg/m^2 was 13%,the emergence rate of 5.0 kg/m^2 was 17%, the emergence rate of 7.5 kg/m^2 was 25%. 5.0 kg/m^2 was the best dosage and 2.5 kg/m^2 was the second best according to the indexes. 5 kg/m^2 of rotten chicken manure was most suitable for seedlings of Broussonetia papyrifera.
