作者对水涨龙眼结果母枝与果穗生长的关系进行了研究。结果表明,结果性能良好的结果母枝,其粗度主要分布范围为0.60—0.90厘米,长度为5—13厘米,复叶数为5—8个。结果母枝粗度与果穗生长关系最为密切,可作为衡量结果性能的主要生物学指标。提高结果母枝粗度可明显增加果穗重量,从而提高龙眼产量。当结果母枝粗度增加,果实数量相应增多时,其果穗会出现小果数增多和单果重下降的现象,可能与树体营养水平有关。上述研究结果,可为制定培养优良结果母枝的综合农业栽培措施提供重要依据。
The authors studied the relationship between the fruit-branch growth and ear growth of longan fruits. The results showed that the results of good performance of the parent branch, the thickness of the main distribution of 0.60-0.90 cm, length of 5-13 cm, the number of compound leaves 5-8. Results The thickness of parent branch was most closely related to ear growth, which could be used as the main biological index to measure the performance of the result. Raising the result The thickness of the parent branch can significantly increase the weight of the ear, thereby improving the production of longan. When the thickness of the parent branch increased and the number of fruit increased correspondingly, the number of small fruit increased and the weight of single fruit decreased, which may be related to the nutrition level of the tree. The results of the above study can provide an important basis for formulating comprehensive agricultural cultivation measures for cultivating good result mother plants.
