Effect of Controlled Release Fertilizer on the Yield and Quality of Banana and Nutrient Use Efficiency

摘要: 为探讨缓控释肥料在香蕉上的应用效果,在漳州香蕉主产区进行了田间试验。结果表明,在中等肥力条件下,施用缓控释肥比等量NPK化肥具有显著水平的增产效果,平均增产量为2 204.7kg.hm-2,增产率为6.18%;缓控释肥对香蕉可溶性固形物含量、可食率有增加的趋势;香蕉果实和茎叶对施用缓控释肥的N、P、K吸收量分别为277.44、33.43、974.51kg.hm-2,香蕉N、P、K利用率分别为15.1%、17.4%和34.7%,比等量NPK化肥的养分利用率分别提高42.7%、1.2%和10.4%。

Abstract: A field experiment was conducted to study the effect of controlled release fertilizer CRF on banana in Zhangzhou of Fujian province.The results showed that the yield of banana after application of CRF was increased by 6.18%(2 204.7 kg·hm-2) and the total soluble solids and edible part ratio were also increased compared with the normal NPK fertilizers at medium soil fertility.Meanwhile,the uptakes of N,P and K were 277.44,33.43 and 974.51 kg·hm-2,respectively,and the utilization efficiency of N,P and K were 15.1%,17.4% and 34.7%.Our results suggest that,compared with the normal N,P and K fertilizers,the use efficiency of CRF were increased by 42.7%,1.2% and 10.4%,respectively.
