摘要:
通过对长山核桃容器苗进行不同微生物菌肥穴施试验,探讨菌肥对长山核桃容器苗生长及生理状况的影响。结果表明,对长山核桃一年生容器苗施用溶磷菌、解钾菌和溶磷菌解钾菌混合菌肥均可促进苗木高生长和地径生长,增加苗木的生物量,且提高叶片叶绿素、可溶性蛋白及可溶性糖的含量。其中溶磷菌对长山核桃容器苗的施肥效果优于解钾菌,混合菌肥的效果不如单施肥的效果。

Abstract:
Effects of different bacteria fertilizers on the growth and physiological conditions of the containerized pecan seedlings were determined. The results showed that application of phosphate-dissolving bacteria, potassium bacteria, or mixed bacteria on one-year-old containerized pecan seedlings could promote the growth of height and collar diameter, increase the seedling biomass and chlorophyll, soluble protein, and soluble sugar contents in the leaf. Overall, the effect of phosphate-dissolving bacteria was better than potassium-solubilizing bacteria and the effect of single fertilization was better than mixed bacteria on the growth and development of the containerized pecan seedlings.
Key words:  microbial fertilizer  Carya illinoensis  container seedling  growth index  physiological characteristics
