Abstract
The effect of nitrogen (N) fertilizer rate and the incorporation of corn stalks residue on the soil microbes in the blueberry root zone was determined in a pot experiment.
The result showed that the microbe quantity had a higher level in the treatment by adding 5% stalks of soil weight with 1% nitrogen fertilizer of stalks weight, which the average quantity of bacteria, actinomyces and fungi being 182, 125 and 146% compared to the control of peat incorporation of garden soil during the annual growth period respectively, accounted for 86.1, 12.5 and 1.33% of total microorganisms, respectively.
The dynamic variations of bacteria, actinomyces and fungi in blueberry root-zone showed a low-high-low trend in the annual growth period.
The quantity of rhizosphere microbes of blueberry was higher than non-rhizosphere which showed the obvious rhizosphere effect (R/S>1).
