摘　　要：分析叶面喷施不同剂量微生物制剂对油松幼苗生长,在山东省某油松林地开展试验,依据BGB微生物菌剂的剂量分为四个处理,CK(不做任何处理)A1(10g/株)A2(30g/株)A3(50g/株),观察不同量的微生物制剂对油松幼苗生长以及土壤养分的影响。结果证实,不同剂量微生物制剂均对油松幼苗生长产生影响。各处理的苗高、地径和冠幅从大到小排序是A3>A2>A1>CK(P<0.05)整体而言,A3处理的油松幼苗长势最好;不同剂量微生物制剂不同时期的幼苗成活率均高于CK组,随着微生物制剂剂量的增加,其成活率逐渐增高,呈正相关趋势。净光合速率、气孔导度、蒸腾速率对比,从大到小依次是A3>A2>A1>CK,整体而言,A3处理优势明显;A3处理的有机质、碱解氮、速效磷均高于其他处理(P<0.05),A3速效钾极显著高于CK组(P<0.01),显著高于A1组和A2组(P<0.05),呈A3>A2>A1>CK的趋势。由此可知,叶面喷施微生物制剂也促进油松幼苗的生长,改善土壤养分,以50g/株的剂量最佳。The analysis of foliar spraying dosage for seedling growth,in Shandong province forest test,according to the dose of BGB microbial agent into four treatments,CK(no treatment)A1(10g/strain)A2(30g/strain)A3(50g/strain),observe the effect of different amounts of microbial preparation on seedling growth and soil nutrients.The results confirmed that different doses of microbial agents affected the growth of Pinus tabulaeformis seedlings.The seedling height,ground diameter and crown amplitude of each treatment were ranked by A3>A2>A1>CK(P<0.05).Overall,A3 treated seedlings showed the best growth;the survival rate of seedlings of different doses of microbial preparations was higher than that of CK group.With the increase of microbial dose,the survival rate gradually increased with a positive correlation.The comparison of net photosynthetic rate,stomatal conductance and transpiration rate was A3>A2>A>A1>CK.Overall,A3 showed obvious advantages;organic matter,alkali nitrogen,and quick phosphorus were all higher than other treatments(P<0.05),A3 was significantly higher than CK group(P<0.01),significantly higher than A1 and A2(P<0.05),showing the trend of A3>A2 A 1>CK.This shows that the foliar spraying of microbial preparation also promotes the growth of Pinus tabulaeformis seedlings and improves the soil nutrients,with the best dose of 50g/plant.
