摘要
【目的】筛选出适合幼龄枣树的施肥方案。【方法】在枣树整个生育期对树体营养指标进行测验,应用DPS统计进行显著性分析。【结果】施肥方案2,幼龄枣树株高、二次枝粗度、主干干径、新梢增长量、叶片面积、叶绿素含量以及叶片氮、磷、钾的累积吸收较佳,产量较高,比较适合幼龄枣树的施肥。【结论】与CK及其它施肥方案相比,试验方案2(萌芽期N+P2O5+K2O:19.2 kg/667m2+19.2 kg/667m2+11.6 kg/667m2,开花期N+P2O5+K2O:8 kg/667m2+12 kg/667m2+10 kg/667m2,坐果期N+P2O5+K2O:6.7 kg/667m2+6.7 kg/667m2+16.6 kg/667m2)较好。
【Objective】To select suitable fertilizer application scheme for young jujube trees through the experiment.【Method】The nutrition of tree body indicators in the whole growth period of Jujube was tested and DPS statistics was applied to carry out the significance analysis.【Result】The indexes of plant height,secondary branch coarse,trunk diameter,shoot increment,blade area,chlorophyll content,accumulation and absorption of N,P,K of young jujube treated by this fertilization were better than those of the CK,and they yielded higher output.【Conclusion】Fertilization experiment scheme 2（ germination stage： N ＋ P2O5＋ K2O： 19. 2kg/667m^2＋ 19. 2 kg /667m^2＋ 11. 6 kg /667m^2,Blossom period： N ＋ P2O5＋ K2O： 8 kg /667m^2＋ 12 kg /667m^2＋ 10 kg /667m^2,Fruiting period： N ＋ P2O5＋ K2O： 6. 7 kg /667m^2＋ 6. 7 kg /667m^2＋ 16. 6 kg /667m^2） was more suitable for young jujube.
