特效植物营养素对龙眼增产效果及相关性状的影响

Effect of increase yield and related traits by SPNE on longan

用特效植物营养素(SPNE)在龙眼采收前2个月进行系列试验,比较SPNE喷施3次、喷施1次和KH2PO4对照的果实产量、商品产量及对影响产量的相关性状进行研究。结果表明:SPNE处理提高了单果重量、果实数、可溶性固形物、糖和维生素C的含量、果肉的质量,增加了果枝的粗度,增强了抗大风雨的能力,落果少,使每穗结果数比对照明显增加,取得了显著的增产效果,喷施3次的效果最好。

SPNE（Special plant nutritional element）was sprayed three times, once to plant of longan before two month when fruit ripe for the picking, compared fruit yield, commodities yield and researched the related traits that influence yield of longan. The result, showed that the longan plant treated by SPNE, and weight of fruit, fruit number, content of soluble solids, sugar and vitamin C,quality of fruit all were improved. The fruit number of each ear be increased obviously for branch more strong then fruit not easy fall from trees when faced storm. Effect of increase yield was remarkable for sprayed SPNE to the plant, the best was sprayed three times.
