| 摘 要： | 连续3年定点试验表明:龙眼果园施用土壤改良剂有极显著的增产效果,增产量可达0.11～2.96kg/株。还能改善果实质量,增加单果重和果肉率,提高果肉维生素C、可溶性糖和固形物含量,并提高土壤pH值、代换性Ca和Mg含量,在肥力水平低的土壤上施用土壤改良剂能使土壤有效N、P2O5和K2O含量分别提高1.28、9.0、4.0倍。改良剂适宜施用量为6kg/株。 |

| Abstract: | Results of field experiment over successive3years sho wed that applying soil amendment could obviously increase the production of lon gan.The yield per tree was increased by0.11～2.96kg;the fruit weight ,flesh edible ratio,soluble solids and ascorbic acid content were also increa sed.Applying soil amendment could much improve soil nutrients,increase soil p H,exchangeable Ca ,and exchangeable Mg.The unfertile soil after amendment ap plied the active N,active P 2 O 5 ,and active K 2 O were increased by1.28,9.0and4.0times respectively.The appropri ate dosage of amendment ap plied was6kg per tree. |
