以中等树势8年生冬枣为试验对象,研究了木质化枣吊摘心对冬枣产量、果实品质的影响。结果表明:木质化枣吊摘心后的冬枣坐果数比不摘心高44.59%,明显提高了产量;摘心后果实纵、横径均有所降低,平均单果重比不摘心的降低了3.7%,但总产量明显提高,果实着色较好,果肉维生素C、总糖、可溶性固形物含量分别提高了7.14%、8.37%和4.29%;而木质化枣吊摘心后的冬枣果实硬度、还原糖含量、总酸含量均降低。因此,可以认为木质化枣吊摘心明显提高了冬枣果实的品质和产量。 Taking 8-year-old jujube with medium tree vigor as test object, the effects of ligninizing jujube-picking on heart jujube yield and fruit quality were studied. The results showed that the number of winter jujube fruit after the topping of lignified jujube was 44.59% higher than that of the uncut heart, and the yield was obviously increased. The vertical and horizontal diameter of the fruit after the topping was decreased and the average fruit weight was reduced by 3.7% The yield of vitamin C, total sugar and soluble solid were increased by 7.14%, 8.37% and 4.29% respectively; while the hardness, reducing sugar content, Acid content decreased. Therefore, it can be considered that the longevity of the woody jasmine significantly improves the quality and yield of jujube fruit.
