摘要 以大石早生李和黑宝石李为试验材料,研究了不同氮磷钾肥配比对李产量及品质的影响。结果表明:施用较高的氮磷钾肥有利于提高李果的产量和单果重,但适宜的氮磷钾肥配比更有利于改善李果的糖度和提高果实中的营养元素的含量。综合经济效益和环境效益,大石早生李的较合理氮磷钾比例为处理2(N∶P2O5∶K2O=1∶0.5∶1)和处理6(N∶P2O5∶K2O=0.5∶0.2∶1);黑宝石李较佳的比例为处理6(N∶P2O5∶K2O=0.5∶0.2∶1)和处理4(N∶P2O5∶K2O=1∶0.2∶1)。 Base on the experimental material of Friar plum and Prunus salicina.Effect of N,P,K fertilizer application methods on yield and quality of plum was studied.The results showed that fertilization of higher level of ratio of N,P,K fertilizer could increase the yield and weight of Plum;N,P,K applicable ratio of fertilizer could improve the content of fruit sugar and the content of nutritive elements;Integrated the relations of economic efficiency and the environmental benefit.The process 2(N∶P2O5∶K2O =1∶0.5∶1) and the process 6(N∶P2O5∶K2O =0.5∶0.2∶1) were suitable proportion of N,P,K fertilizer of Prunus salicina.The reasonable proportion of N,P,K fertilizer of Friar plum were the process 6(N∶P2O5∶K2O =0.5∶0.2∶1) and process 4(N∶P2O5∶K2O =1∶0.2∶1).
