| 中文摘要: |
| 为提高‘蜂糖李’产量，改善果实品质。本研究以9年生‘蜂糖李’为试材，研究了4个负载量水平，即201~400个果实/株(T1）、401~600个/株（T2）、601~800个/株（T3）和800个/株以上（T4）对其产量和果实品质的影响。结果表明，随着负载量的增多，产量随之增加，而单果重和果实品质则降低。其中单株负载量在601~800个，果实的整齐度最佳，产量为27.76kg/株，显著高于T1和T2；T3可溶性固形物含量高达19.63%，糖酸比44.98，维生素C含量为3.32 mg?(100g﹣1)，产量和品质表现良好。合理的负载量能提高‘蜂糖李’的产量和品质，单株控果量在601~800个间最适宜。 |

| In order to increase yield and improve fruit quality.Nine-year-old ‘Fengtang plum’trees were used in the experiment. Four fruit loads levels were designed including (201-400)fruits/tree (T1),401-600 ones/tree(T2), 601-800 ones/tree(T3) and 800-above-ones/tree(T4) were design to study the effect of fruit loads on yield and fruit quality. The results showed that as the load arose, the yield increased, but the fruit weight and quality decreased. Among them, when the load per tree was 601~800 fruits per tree(T3), the fruit uniformity was the best, and the yield was 27.76kg/plant, significantly higher than T1 and T2 treatment. T3 treatment also showed better fruit quality with soluble solid content up to 19.63%, sugar-acid ratio up to 44.98, and vitamin C content up to 3.32 mg?(100g﹣1), yield and quality are good. Therefore, in this study, we concluded that a reasonable load can improve the yield and quality of ‘Fengtang plum’, and the optimal fruit load per tree is between 601- 800. |
