摘　　要：在落叶松、沙棘育苗地施用生物有机肥料 ,以改善其土壤微生态环境 ,提高落叶松、沙棘育苗成活率 ,加快落叶松、沙棘苗的生长 .试验结果表明 :生物有机肥料可以提高红松育苗地的微生物数量 ,改善 pH值、有机质及速效N ,P ,K等微生态指标 。Bio-organic fertilizer was used in the fields of young plants of Larix olgensis and Hippophase rhamnoides L. to improve their micro-ecologies and raise the rate of young plants of Pinus koraiensis and quicken their growth. The results are that the bio-organic fertilizer can markedly improve the micro-ecologies of fields of young plants of Larix olgensis and Hippophase rhamnoides L.,such as the quantity of microbes,pH value, the containing of organic matter,and the dissoluble N,P,K. In the end, bio-organic fertilizer can quicken the growth of the young plants of Larix olgensis and Hippophase rhamnoides L. .
