摘要
2009年3月在南京林业大学植物生长室采用荧光假单胞解磷细菌(JW-JS1)及红绒盖牛肝菌外生菌根真菌(Xc)2种菌剂接种,通过温室盆栽30天、60天、90天、120天及150天后,测定其对NL-895杨生长和光合特征的影响。结果表明,JW-JS1、Xc单接种和双接种均能明显促进NL-895杨的生长和改善植株的光合特征,且双接种效应优于单接种。双接种150天后,NL-895杨的苗高、地径、生物量、侧根数和菌根侵染率分别比对照增加了24.79%、23.60%、56.35%、150.00%和64.11%;双接种在增加NL-895杨叶片叶绿素含量和改善其净光合速率(Pn)、蒸腾速率(Tr)和气孔导度(Gs)上表现出显著的正交互效应。研究结果为减少林业生产中化肥的施用量和开发杨树复合菌肥提供了理论依据。
The effects of Psudomonas fluorenscens （JW-JS1） and Xerocomus chrysenteron （Xc） inoculation on growth and photosynthesis characteristics of NL-395 poplar under pot conditions were studied. The results indicated that inoculation of JW-JS1, Xc and combined inoculation of these two microorganisms could significantly promote the growth and photosynthesis characteristics of NL-395 poplar, the effect of co-inoculation was better. One hun- dred and fifty days after inoculation, the seedling height, basal diameter, biomass, number of lateral roots and mycorrhizal colonization ratio were 24.79%, 23.60%, 56. 35%, 150.00% and 64. 11% respectively than the control. There was positive interaction effect on photosynthetic rate （Pn）, transpiration rate （Tr）, stomatal conductance （Gs） and chlorophyll content of NL-895 poplar when inoculated with JW-JS1 and Xc. Therefore, the study could provide theoretical basis for reducing the quantity of chemical fertilizer application in the forestry production and developing the compound microbial fertilizer for poplar.
