Effects of basal application of potassium fulvic acid on the vegetative growth and fruit quality of bayberry in greenhouse
In order to study the effect of potassium fulvic acid as a humic acid fertilizer on the vegetative growth and fruit quality of bayberry in greenhouse,18-year-old full bearing Dongkui bayberry trees in greenhouse were used as material.The mineral potassium fulvic acid of 500 g/plant as base fertilizer applied in autumn was set as treatment and application of water as control(CK).The results showed that compared with CK,the shoot length,leaf length,thickness of 10 leaves and chlorophyll SPAD value of spring shoots of treated bayberry were increased by 36.16%,13.06%,26.23%and 0.77%,respectively,with significant differences in shoot length,leaf length and leaf thick-ness.The single fruit weight,soluble solid content,total sugar content,vitamin C content,total flavone content and anthocyanin content of treated bayberry were increased by 6.03%,3.73%,5.74%,5.32%,2.11%and 6.90%,respectively,and the total acid content was decreased by 9.42%.Except for the total flavone content,the other pa-rameters were significantly different.In conclusion,basal application of potassium fulvic acid can effectively promote the vegetative growth,and significantly improve the fruit quality of bayberry,which has good popularization and ap-plication value in production.
