摘　　要：以石硖龙眼为试材,通过花穗短截及疏除花穗等不同处理,对龙眼树叶营养及果实品质的影响进行对比试验。结果表明,花穗短截+疏除花穗处理使石硖龙眼树体的氮、磷、钾元素的含量保持相对较高的水平,明显提高龙眼果实可溶性固形物含量、可溶性糖含量及还原糖含量,改善果实品质,优于其他处理。Longan cv. Shixia is as test materials for this experiment, for the target yield of producting 1000 kg fruit at 667m2,according to trunk perimeter for yield per plant （y=0.0125c2, y：production （kg）,0.0125 for constant,c for trunk perimeter）,on the basis of ensuring that 500g fruit per cluster, through the following four kinds of processing, （1） Short cut flowers spikes; （2） Thin redundant spend spikes; （3） Short cut flowers spikes ＋ thin redundant spend spikes （4） control. Ensure the number of grains for every plant. To study the content of blade total nitrogen, total phosphorus, total potassium of different periods and the content of Soluble sugar, reducing sugar, titratableacid and TSS of fruits on harvest.The results indicate that： processing（3） makes the content of blade total nitrogen, total phos- phorus, total potassium highest of longan cv Shixia, improve the content of TSS,Soluble sugar, reducing sugar of fruits significantly, processing（3） is better than other processings.
