Experimental study on effect of application of biogas slurry in production of Platycodon grandiflorum
In order to ascertain the effects of firedamp liquid on yield increase of Platycodon grandiflorum, promote biogas fertilizer utilization technology progress, promote the healthy development of the industry of platycodon grandiflorum, we launched the firedamp liquid on experimental study on effect of platycodon grandiflorum. Controlled trials through the fields and analysis of variance test data, basically to ascertain the effects of firedamp liquid on yield of Platycodon grandiflorum. Results showed that in late April and late July spraying 600 kg/667 m2 biogas slurry one time at concentration 75%, or in mid-April, June and August spraying 300 kg/667 m2 biogas slurry one time at concentration 75%, the yield-increasing inereased significantly.
