摘　　要：以甜柿砧木泰富容器苗为试材,研究不同缓释肥施用量对其生长的影响,以筛选最佳缓释肥施用量。结果表明,不同缓释肥施用量的容器苗在生长、生理方面存在显著差异,以育苗袋内缓释肥用量为105 g/袋·年的植株综合表现最好,株高、苗基部粗度、苗总鲜重、地上部分鲜重、地下部分鲜重均高于其他施用量。可作为泰富砧木苗木培育期间的推荐施肥量。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,among which the D3 treatment(105 g/bag year of slow-release fertilizer)had the best overall performance,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 amount for Taifu seedling cultivation.
