绿洲植物营养液对龙眼、荔枝生长结果的影响

分别根据荔枝和龙眼的物候期，于采果后沿树冠滴水线开沟浇施２５０倍的绿洲植物花果营养液，并在花果期喷施３次５００倍的绿洲植物花果营养液，可使植株生长健壮，叶片增厚，叶色浓绿、光泽度提高；并能不同程度提高龙眼和荔枝的座果数、单果重和单株产量．株产提高幅度因品种而异，本地种龙眼提高６１％，赤壳龙眼提高４６％；兰竹荔枝提高９０％以上，而乌叶荔枝仅提高１０％右左．绿洲植物营养液有利于提高果实品质，使果粒均匀发育，大小一致．龙眼果实品质测定的结果表明，Ｖｃ含量提高４３％，还原糖、可溶性固形物等也有不同程度的提高．

Effects of Qasis Plant Nutrient Solution on Growth and Fruiting of Longan and Litchi

According to the developmental cycle of longan and litichi,respectively,250times soluted Oasis Plant Nutirent Solution (OPNS,specially used for root)was applied into the soil under the tree-crow after fruit picking and 500 times soluted OPNS (specially used for flower and fruit) was spread 3 times during the developmental stage of the flower and fruit.As a result, plant strongly growing,leaf thickening, greening and lightening,and fruit uniforming were gained;and number of fruit-set,weigh of fruit and single plant yield increased.The single plant yield of various litchi and longan varieties increased as follows:Lanzhu litchi being 91%,Wuye only 10%,Bendizhong longan 61% and Chike 46%.Quality of fruit in Shuizhang longan was improved by spread the OPNS,Vc increased 43%,solutive solid and sugar increased in some content,too.
