EFFECT OF DIFFERENT PROPORTION OF CORN STALKS AND NITROGEN FERTILIZER ON SOIL MICROBE QUANTITY AND RHIZOSPHERE EFFECT OF BLUEBERRY ROOT ZONE
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).
