摘要
为了提高无花果果实品质与耐贮性,以无花果品种布兰瑞克为试材,进行果实生长发育期追施钾肥对果实品质与贮藏性能影响的研究。结果表明:适量增施钾肥能提高无花果采收时可溶性固形物含量和维生素C含量,降低果实可滴定酸含量;减缓冷藏期间果实可滴定酸含量的下降,抑制果实可溶性固形物含量的上升和维生素C的损失,较好地保持了果实的品质,提高了果实的耐贮性。无花果每年每株2次追施1.0 kg氯化钾时,果实贮藏效果最佳。
In order to improve the fruit quality and storability of Ficus carica,the effects of the application of potassium fertilizer on fruit quality and storability of F.carica fruit in growth and developmental periods was studied.The results showed that appropriate amount of potassium fertilizer could increase the contents of soluble solids and vitamin C in harvest,and reduce titratable acid content in fruits;slow down the reduction of fruit titratable acid content under refrigeration,inhibit the increase of the content of soluble solids and losses of vitamin C,and well preserve the quality of fruit and its storability.The best storage effect was achieved by applying 1.0 kg potassium chloride each tree for two times.
