摘　　要：根据土壤养分测定结果制定施肥措施,进行固体肥料和液体肥料的对比试验。结果显示,通过灌溉施肥系统进行液体肥料施用,能促进荔枝对养分的吸收,其叶片氮、磷、钾、钙、镁、硼、锌含量比对照分别提高11.5%、19.4%、12.6%、32.6%、34.0%、32.0%和24.4%,产量增加43.8%,可溶糖含量和固形物含量比对照提高7.2%和13.1%,具有显著的节肥增收效应。The contrast test of fluid fertilizer and solid fertilizer based on soil nutrient status was conducted to study the effect of fluidfer tilizer on the yield and quality of litchi. The results showed that the application of fluid fertilizers through irrigation system was more effective. Compared with the treatments of solid fertilizer applied, the yield of litchi increased by 43.8%, and the absorption rate of N, P, K, Ca, Mg, B, Zn enhanced by 11.5%, 19.4%,12.6%, 32.6%, 34.0%, 32.0% and 24.4%, respectively. The litchi applied with fluid fertilizer had better fruit quality that the contents of soluble sugar and solid were higher than that of control with 7.2% and 13.1%.
