肥料的合理施用对提高荔枝的座果率和产量有很大的影响。据报道,荔枝的正常生长发育除需要较多的氮、磷、钾大量元素外,还需要少量的硼、锌、镁、钙等微量元素的供给。荔枝树寿命长,栽活之后,可连续生长数十年至数百年,每年在土壤中吸取所需的各种营养元素。由于过去施肥多偏施氮肥,也施少量的磷、钾肥, The rational application of fertilizers to improve litchi fruit yield and yield have a great impact. It is reported that litchi growth and development in addition to the larger need for a large number of nitrogen, phosphorus and potassium elements, but also require a small amount of boron, zinc, magnesium, calcium and other trace elements in the supply. Lychee tree long life, after planting, the continuous growth of tens to hundreds of years, every year in the soil to absorb the various nutrients required.
