重金属和生物有机肥对苹果根区土壤微生物的影响

Shuitu Baochi Xuebao, 2005
通过土壤追施Cd ,Cu和生物有机肥,研究了重金属对红富士苹果根区微生物的危害以及生物有机肥减轻重金属对土壤微生物危害的效应。结果表明:施用生物有机肥后,果园根区土壤细菌、真菌和放线菌数量显著增加,细菌占绝对优势;土壤Cd浓度在10 30mg/kg范围内,随Cd浓度的增加,细菌数量大幅度减少;Cu元素对土壤微生物的危害情况与Cd相似,但程度比Cd轻;从生物有机肥中提取的有机质对Cd和Cu有明显的吸附作用,在pH值6～8的范围内,吸附率随pH升高而提高;在中性微酸的条件下(最适宜苹果栽培的土壤酸碱条件) ,

新疆野苹果腐烂病病原菌鉴定及诱导宿主抗病相关基因表达分析

, 2018
近十年来，由于多种原因，新疆野苹果林遭受了毁灭性的生态危害，大面积的野苹果纯林衰败甚至死亡，腐烂病的爆发成为野苹果林大面积死亡的重要原因之一。苹果树腐烂病不仅是天山野果林中新疆野苹果的主要病害，也是我国乃至世界性的栽培苹果生产中的毁灭性病害，是制约我国苹果安全生产和危害世界苹果产业的主要限制因子。已有研究对分离自栽培苹果（Malus domestica）的腐烂病菌进行了分离与鉴定，认为主要是黑腐皮壳菌（Cytospora mali，又名 Valsa mali）对宿主栽培苹果造成了危害，但是 ...
