以传统常规施肥模式为对照,研究了‘砂糖橘’滴灌施肥的效果。结果表明,在比常规(开沟和撒施)施肥氮、钾用量分别减少42.9%、41.9%的情况下,滴灌施肥处理‘砂糖橘’果实品质与对照无差别,产量比对照略有增加,试验3年全园产量比试验前明显提高。滴灌施肥处理土壤N、K含量在适量范围,P、Mn含量处于过量水平,Ca和Mg含量处于低量水平,其他微量元素含量处于适量范围;叶片P、K含量处于适量范围,N处于低量水平,Ca、Mn含量偏高,Mg、Zn、B含量在适量范围。滴灌施肥处理施肥用工量比常规节省66.8%,每667 m2劳动力成本和肥料成本比对照节约128.92元。
Taking the traditional fertilization mode as a control, the effect of drip fertilization on the sugar orange was studied. The results showed that there was no difference between the control and the quality of ’Zizyphus citri’ fruit after drip irrigation at a rate of 42.9% and 41.9%, respectively, compared with conventional (ditching and spreading) Test 3 years the whole garden output was significantly increased than before the test. The content of N and K in soil was in the range of proper amount, the content of P and Mn was excessive, the content of Ca and Mg was in the low level, while the content of other trace elements was in proper range. The contents of P and K in leaves were in proper range and N was low Level, Ca, Mn content is high, Mg, Zn, B content in the appropriate range. Drip fertilization fertilization 66.8% of the work than conventional savings, labor costs and fertilizer costs per 667m2 compared with the control of 128.92 yuan.
