荔枝生产存在结果少、产量低,影响经济收入,限制着荔枝生产的发展。影响荔枝产量因素是多方面的,氮素营养是荔枝营养中重要元素之一,施肥合理能提高产量,施肥不当反而使产量降低,所以,在栽培上有低肥高产,高肥低产的倾向,因此,合理施肥研究是重要的。 Litchi production results less, low yield, affecting economic income, limiting the development of litchi production. Litchi yield factors affecting many aspects, nitrogen nutrition is one of the important elements of litchi nutrition, fertilization reasonable to improve yield, but not to fertilize but lower yields, therefore, the cultivation of low-fat and high yield, high yield and low propensity, Therefore, rational fertilization research is important.
