Abstract:

In order to investigate the improvement effect of different soil conditioners on the quality and yield of ginger in continuous cropping greenhouse,a field plot experiment was conducted with five treatments:control,bio-organic fertilizer,bio-organic fertilizer combined with biochar,bio-organic fertilizer combined with humic acid,bio-organic fertilizer combined with foliar silicon fertilizer. The changes in quality,yield and growth indexes of ginger were analyzed. The results showed that compared with the control,the plant height of ginger significantly(p<0.05)increased by 19.0-22.2 cm,the number of tillers significantly increased by 1.8-2.5,fresh weight of stem and leaf significantly increased by 45.9%-54.9%,fresh weight of rhizome significantly increased by 11.7%-20.7%,yield significantly increased by 26.8%-33.6%,and gingerol content significantly increased by 0.34-0.48 percentage point when treated with bio-organic fertilizer combined with biochar,humic acid,or foliar silicon fertilizer. The contents of Cd,Cr and Ni in ginger were significantly decreased by 31.1%,23.3% and 48.8% when treated with bio-organic fertilizer combined with humic acid,and the content of Pb in ginger significantly decreased by 21.8% when treated with bio-organic fertilizer combined with foliar silicon fertilizer. In conclusion,bio-organic fertilizer combined with biochar,humic acid or foliar silicon fertilizer can improve the quality and yield of ginger,and the best one is bio-organic fertilizer combined with humic acid.
