摘要

采用稀释平板测数法和最大或然数法研究樱桃年生长周期内不同樱桃砧木(大青叶、山樱、考特和马哈利)对根际与非根际土壤微生物数量动态变化的影响。结果表明

樱桃年生长周期内

4种樱桃砧木根际与非根际土壤微生物数量与其生长发育呈正相关

即土壤微生物数量从萌芽期开始增加

在开花期、坐果期或成熟期达到峰值

落叶期有所下降。不同樱桃砧木根际土壤微生物各生理类群数量差异显著

且均以细菌占绝对优势

放线菌次之

真菌最少。各樱桃砧木土壤微生物数量呈现根际效应。土壤根际微生物多样性指数的变化趋势与土壤根际微生物总数的变化趋势不一致。因此

选择合适的樱桃砧木

有利于土壤微生物数量的提高

从而为樱桃树生长创造良好的土壤微生态环境。

Abstract

Using dilute plate counting method and most probable number method

the dynamic of rhizosphere soil microbial quantity was studied during cherry annual growth period under four kinds of cherry rootstocks(Cerasus pseudocerasus

Cerasus sachalinensis Colt

Cerasu smahaleb). The results showed that soil microbial quantity was positively related to the cherry annual growth stages-soil microbial quantity began to rise at germination period and quickly reached its peak at flowering

fruiting or maturation period

but decreased slightly at leaf fall period. The numbers of microbial physiological groups were significantly differences cherry rootstocks

and bacteria was dominant

followed by actinomycetes

and fungi was the least. Soil microbial quantity presented rhizosphere effects. The change trends of total amounts of soil rhizosphere microorganisms and biodiversity indices were different among cherry rootstocks. Therefore

choosing suitable cherry rootstock varieties can be beneficial to increasing the number of soil microorganisms

and create a good micro-ecological environment for the growth of cherry trees.
