Abstract:

利用保绿法和萝卜子叶增重法从7年生甜樱桃[cerasuspseudocerasus(lindl.)g.don]根际土壤中,筛选具有促生作用的植物根际促生细菌yt-3(pgpr),以发酵好的鸡粪(dcm)为吸附载体制成甜樱桃专用的pgpr生物肥料(ymf),对比研究了ymf、普通生物肥(nmf)和dcm对樱桃根系和根际土壤生物学特征的影响.结果表明:ymf显著增加了根际土壤中细菌数量和微生物总量,真菌数量明显减少,但对放线菌数量影响差异不显著.ymf处理根系活力分别比nmf、dcm和ck提高了22.49%、13.25%和15.33%.pgpr生物肥料对樱桃根系生长和构建影响显著,ymf处理0~40cm土壤剖面中根系重量尤其是毛细根重量显著增加.同nmf处理相比,ymf处理根际土壤的ph降低8.61%,阳离子代换能力显著提高.此外,ymf处理显著增加了根际土壤中养分离子的有效性,速效磷和有效钾含量分别增加17.21%和9.56%,但碱解氮含量差异不显著.因此,pgpr生物肥的施用在一定程度上改善了根际土壤的生态环境,提高了根际土壤中养分离子的有效性和养分保持能力,提高了根系活力,促进了表层土壤中(主要为0~40cm)根系尤其是毛细根的生长.图2表3参17
