南方鲜食枣二次枝结果特性

Bearing fruit properties of secondary branches in southern fresh jujube

为充分了解南方鲜食枣的结果特性,以"中秋酥脆枣"为试材,调查研究二次枝不同二次副梢的现蕾、开花和坐果规律以及不同节位的现蕾数、开花数和坐果数,对比分析不同二次副梢的开花率、座果率及成果率。结果表明:二次枝不同二次副梢的现蕾、开花和坐果规律的变化趋势大致相同。所有二次副梢的现蕾数和开花数都随着节位的升高而减少,二次副梢的坐果数随着节位的升高呈现先升高后降低,再升高再趋于平稳的变化趋势。二次枝不同二次副梢的现蕾数、开花数和坐果数的变化趋势相同,随着节位的升高反而减少。Ⅱ的总现蕾数、开花数和坐果数的最多,其次是Ⅰ,Ⅲ至Ⅷ。不同二次副梢的开花率、座果率和成果率存在差异。Ⅱ的开花率及座果率最大,Ⅳ、Ⅴ的成果率最大,Ⅷ的开花率、座果率和成果率都最小。

In order to fully understand the bearing fruit properties of fresh jujube in South China,a variety of Fresh Zizyphus jujube cv.in Southern China called Mid-Autumn festival jujube was used as test materials.This paper studied the law of budding,flowering and fruit setting of different secondary shoots of secondary branches and the number of buds in different nodes,and the flowering rate,fruit setting rate and fruit rate of the secondary shoots were compared and analyzed.The results showed that the trends of buds,flowering and fruit setting of secondary side shoots of secondary branches were almost the same.The number of buds and flowering numbers of all secondary side shoots decreased with the increase of node number,and the fruit number of secondary side shoots increased first and then decreased,then increased and then became stable.The trend of the bud number,flowering number and fruit number of secondary side shoots of secondary branches was the same,but decreased with the increase of nodes.The total number of blooming buds,flowering number and fruit setting number of the No.2 secondary side shoot were the highest,followed by No.1,No.3 to No.8.The flowering rate,fruit setting rate and fruit rate of different secondary side shoots were different.The rate of flowering and fruit setting of No.2 were the highest,the rate of the No.4 and No.5 were the highest,and the rate of flowering,fruit setting and fruit setting of No.8 were the least.
