摘要:【目的】探究微生物菌肥对减少革果花脸病发生,提高产量和果实品质的作用。【方法】以5年生烟富 3/M26/平邑甜茶苹果为试材,采用15N同位素示踪技术,于20152016年进行了2年田间试验。设3个处理:花脸病树施化肥(CK)、健康树施化肥(T1)、花脸病树施化肥+微生物菌肥(T2)。分别于2015年10月12日和 2016年10月15日,每个处理随机采集100个果实,统计花脸病病情指数,并于2016年10月15日对整树进行破坏性取样,测定"N吸收利用情况。【结果】施化肥+微生物菌肥花脸病革果树(T2)根系生物量及新梢长

Abstract: [ Objective J This paper studied the effects of microbial fertilizer on alleviating the Baikal disease and growth, nitrogen uptake, yield and quality of apple plant. [ Method J Taking the seedlings of the five-year-old'Yanfu 3 '/M26/Malus hupehensis Rehd. as tested material, a two-years' field trial was conducted using "N trace technique. Three treatments were designed: sick apple tree (infected with Baikal disease) applied with chemical fertilizer (CK), healthy tree applied with chemical fertilizer (T1) and sick tree applied with both microbial and chemical fertilizer (T2). A hundred of fruits were randomly picked up from each treatment at fruit ripening period The whole trees were cut down as samples, and the absorption and utilization of the "N were determined.[ Results J 1) The root biomass and new shoot length of apple trees in T2 were significantly higher than those in CK and T1. The dry biomass of fine roots and thick roots, the branch length in T2 were 39.4%, 157.0% and 42.0% higher than in CK, respectively. The Ndff values in CK and T2 were significantly lower than those in T1 in all the
