太子参施用生物菌肥效果初探

本研究以当地传统施肥为对照，采取拌种、基肥、根外追肥等不同方式对太子参栽培增施生物菌肥，结果表明，在柘荣县及其类似生态环境下，施用生物菌肥对太子参有一定程度的增产增效作用。若基肥用复合肥施得多，将推迟地上部生长转入地下部生长的时间，而影响块根产量；若追肥用复合肥施得少，则中后期肥料供应不足植株生长不良，也影响块根产量；只有在基、追肥施用适量复合肥条件下增施生物菌肥，促进植株前期早生快发，中期生长健壮，后期适时正常转入地下生长，才能获得最佳增产效果。

Primary study on the application of biological bacterial fertilizer to Pseudostellaria heterophyUa

Different measures of fertilizing, such as seed dressing, basic fertilizer and foliage dressing, were taken to add bio-baeterial manure to Pseudostellaria heterophyUa （Miq.）. The traditional fertilization was used as a control. The results showed that, in the ecological environment of Zherong County, by adding bio-bactefial manure, the yield and income were increased. However, more compound fertilizer applied as basic fertilizer would put off the time when aboveground growth turn to underground growth, which had decreased roots yield. Less compound fertilizer applied as foliage dressing would decrease the growth at middle and late stages due to the lack of fertilizer, and which also decrease roots yield. Only adding bio-bacterial manure under proper compound fertilizer applied as basic fertilizer and foliage dressing, the plants would grow earlier, more strong at the middle stage, turn to grow underground at the right time at the late stage, so as to gain the highest yield.
