Effect of slow-release fertilizer on the growth of persimmon rootstock Taifu container seedlings
Using the persimmon rootstock Taifu(D.kaki Thunb.)container seedlings as the test material,this study compared and analyzed the growth of Taifu container seedlings in different slow-release fertilizer application amounts by means of semi-underground placement of seedlings in root control bags,in order to screen their optimal slow-release fertilizer application amounts and provide technical support for accurate fertilization during Taifu container seedling cultivation.The results showed that there were significant differences in growth,physiology and chlorophyll content among persimmon container seedlings with different slow-release fertilizer application amounts,a-mong which the D3 treatment(105 g/bag year of slow-release fertilizer)had the best overall per-formance,with higher plant height,ground diameter,total fresh weight,fresh weight of above-ground parts,fresh weight of underground parts than those grown with other application rates.The annual application rate of 105 g/bag of slow-release fertilizer can be used as the recommended a-mount for Taifu seedling cultivation.
