Ｄ优６３水稻谷芽分别用四种菌剂接种，再育苗移栽进行小区比较试验。结果表明，水稻施用不同菌肥（接种剂）的根际效应差异较大，与未用菌肥的ＣＫ相比，差异显著，其中ＦＪ１─Ｎ菌肥的最大，且在不同生育期根际效应亦不一样，从移栽时到齐穗期呈下降趋势。亩产以ＦＪ１─Ｎ菌肥接种的最高，与对照相比增产５．２％，表明根际效应与产量有正相关性 D You 63 rice germ were inoculated with four kinds of fungicides, and then transplanting seedlings for cell comparison test. The results showed that there were significant differences in rhizosphere effects between different bacterial manure (inoculants) and rice varieties, which were significantly different from those of non-used CK, of which FJ1-N was the largest and had the highest rhizosphere effect at different growth stages Not the same, from the time of transplanting to heading a downward trend. The highest yield of FJ1-N inoculation was 5.2% higher than the control, indicating a positive correlation between rhizospheric effect and yield
