摘　　要：在枇杷基肥施用技术中,施用时间是影响花芽分化的重要因素。采用果园和田对比试验对枇杷基肥适宜施用时间进行初步探讨。结果表明:在采果后1个月之内施用基肥的,每施肥1周,全树花芽分化率降低约8.3%;施用基肥的最佳时间在采果后2周以内,花枝比例可达到75.4%以上;在采果后第3周施基肥的,花枝比例达到64.7%,通过人为调控营养生长和生殖生长的平衡,经抹芽定梢后,全树花枝率在70%以上。基肥施用时间以采果后3周内为宜。试验结果可为指导枇杷基肥施用提供一定的参考。For the technique of fertilization for loquat,application time is a key factor affecting flower bud differentiation.Based on the comparison test in the same orchard,the authors conducted a preliminary study on the appropriate application time of base-fertilizer for loquat.The results showed:when fertilizing after fruit-picking within a month,the bud differentiation rate of the whole tree would decline by about 8.3 percent for the delay of a week.The best time for base-fertilizer application was within two weeks after fruit-picking,which could bring a rate of flowering branches to as high as 75.4%.Application at the third week after the fruit-picking would bring a rate of 64.7%of flowering branches,which could be raised to 70%by artificial regulation between vegetative growth and productive growth balance through bud picking.The appropriate application time of base-fertilizer application was within three weeks after fruit-picking.The results can serve as certain guidance for the base-fertilizer application for loquat.
