大果期喷施特效植物营养素对荔枝增产效果及相关性状的影响

Effect of increase yield and related traits by SPNE on litchi big stage

采用特效植物营养素(SPNE)在荔枝采收前1个月喷施植株两次,比较SPNE处理和KH2PO4对照的果实产量、商品产量,对影响产量的相关性状进行研究。结果表明:SPNE处理后提高了单果重量、可溶性固形物的含量、果肉质量;增加了果枝的粗度,增强其抗大风雨能力因而落果少,平均每穗果数比对照明显增加,取得了较大的增产效果。

SPNE （Special plant nutritional element）was sprayed twice to plant of litchi at the time of one month before harvest, and ＇also comparied the fruit yield, commodities yield and the related traits which influenced yield of litchi with CK. The result showed that the weight of fruit, content of soluble solids, quality of fruit were improved with SPNE. The diameter of fruit branch increased obviously, it also made the wind and rain resistance increased to reduce the fallen fruit,the fruit numbers per spikelet was more than CK, the effect of increase yield significantly.
