摘要

[目的] 探索喀斯特山区不同种植年限对山银花产地土壤生物学特性的影响

为促进贵州省山银花的高产优质栽培提供基础数据。[方法] 采用野外采集和室内分析的方法

以贵州省绥阳县不同种植年限山银花根区土壤为研究对象

对比研究了不同年限土壤生物特征。[结果] 随着种植年限的增加

山银花土壤微生物总数和细菌数量(B)在数值上表现为先增加后减少的趋势

放线菌数量(S)和真菌数量(F)呈不断增加的变化趋势;土壤微生物生物量碳、生物量氮和微生物量磷都表现为先增加

后持续减少的趋势;土壤过氧化氢酶和脲酶的活性均有先增加后减少的趋势

土壤磷酸酶有先减少后缓慢增加的趋势;土壤细菌和真菌数比值(B/F)呈先增加后减少趋势

放线菌数量(S)和真菌数量比(S/F)随着种植年限的增加而增加;土壤微生物的Shannon-Wiener指数随着种植年限先增大后减小

Simpson指数和Shannon均匀度指数均随着种植年限呈减少趋势。[结论] 随着种植年限的增加

根区病毒害发病率增大。

Abstract

[Objective] Soil bio-characteristics of Lonicerae hypoglauca with different planting years was studied in karst mountainous area to provide the basic data for the improvement of L. hypoglauca cultivation in Guizhou Province.[Methods] We used the field observation and laboratory analysis in the study. Soil samples from the root zone of L. hypoglauca were collected to investigate soil bio-characteristics with different planting years in Suiyang County of Guizhou Province.[Results] The amount of microorganism and bacteria(B) in the soil increased in the initial planting years and then decreased gradually

while the amount of actinomycetes(S) and fungi(F) in the soil increased continually with the addition of the planting years. Similarly

the content of C

N and P of soil microorganisms showed an increasing trend at the initial planting years and then decreased with the addition of planting years. The activity of both catalase and urease increased initially and then decreased. In contrast

soil phosphatase showed a decreasing trend initially and then increased with the addition of planting years. The B/F ratio of soil increased initially and then decreased. The number of actinomycetes/fungi(S/F) increased with the planting year. The Shannon-Wiener index of soil microorganisms increased initially and then decreased

while both of the Simpson index and Shannon evenness index decreased with the addition of planting years.[Conclusion] Soil fertility declines and the incidence of virus in root zone increases with the addition of planting year.
