Effects of drip infusion on yield and quality for longan

以桂香龙眼品种为试材,开展输液滴灌施肥对龙眼产量及品质的影响试验。结果表明:输液滴灌施肥显著提高了果实品质,单果重、单株产量、可溶性固形物含量和可溶性糖含量等指标均优于常规土施。输营养液和输复合肥处理的比常规土施处理的单果重分别提高了20.62%、25.53%;单株产量分别提高了17.90%、29.44%;可溶性固形物含量分别提高了18.15%、11.40%;可溶性糖含量分别提高了19.43%、7.24%。

Longan cv. Guixiang as the test material the experiment had been carried out to find the effect between drip fertilizing and conventional soil fertilizing. The results showed that drip fertilizing obviously increases the fruit quality. The weight per plant, the yield per plant, soluble solids content and soluble sugar content and so on were all superior to those of conventional soil fertilizing.Compared with conventional soil fertilizing,the two treatment,in- fusing nutrient solution and compound fertilizer,can respectively increase weight per plant by 20.62 % and 25.53 %, the yield per plant by 17.90 %,29.44 %,soluble solids content by 18.15 %,11.40 % and soluble sugar content by 19.43 %,7.24 %.
