摘要：月季是中国传统名花，其花色丰富，黄白黛绿，红紫粉披，五彩缤纷，广泛用于园艺栽培和切花，在世界花卉产业中具有极其重要的地位。为了提高月季观赏价值,本实验选择校园内种植的灌木月季进行物候观测，研究月季营养生长对生殖生长的影响，通过观测月季母枝胸径、长度，花枝胸径、长度，叶片数量、面积，花蕾数量，花朵大小等参数，结果表明：（1）月季进入生殖生长期后，营养器官停止生长，现蕾期花蕾数量保持不变，每个花枝上的花蕾数量不同，开花期开花的数量随时间变化而增多，花朵大小无差异；（2）通过物候数据做出相关分析，发现花枝胸径对花枝长度的影响和花枝的胸径、长度对花蕾数量的影响正相关极为显著，母枝的胸径对花枝长度的影响和叶片面积对花蕾数量的影响正相关为显著，其余（母枝胸径对花枝胸径、花蕾数量的影响；母枝长度对花枝胸径、花枝长度、花蕾数的影响；叶片数对花蕾数的影响）没有显著影响。因此，建议在生产中加强月季生长季前期基肥和重修剪，保证植株有足够的矿质营养可供吸收，以促进花枝的萌发和生长强度，增加花蕾数量，提高其开花质量。20511

Effects of Vegetative growth on Reproduction growth  of  R.chinensis
Abstract：R. chinensis is traditional Chinese flowers, its rich colors, yellow and white , purple pink , colorful , widely used in horticulture and cut flowers, has an extremely important role in the world flower industry. In order to improve R. chinensis  ornamental value, this experiment select shrub R. chinensis  planted in the campus conduct phenological observations, research Effects of Vegetative growth on Reproduction growth  of  R.chinensis, Observing mother branch diameter 、 length, flowering branch diameter 、length, the number of leaves , the area of blade, the number of buds , flower size, the results showed that: (1 ) R.chinensis into the reproductive stage , vegetative organs stop growing, the number of buds remains unchanged in budding stage, the number of flowers bud is different between flowering branch , the number of flowering increase by changing over time, no difference in flower size ; ( 2 )  Making correlation analysis by phenological data and found that effects of flowering branch diameter on flowering branch length  ，effects of flowering branch diameter 、length on the number of buds is extremely significant positive correlation , effects of mother branch diameter on flowering branch length ，effects of leaf area on number of buds is significant positive correlation , and the rest (effects of mother branch diameter on flowering branch diameter、number of buds ；effects of mother branch length on flowering branch diameter 、length、number of buds ；effects of number of leaves on number of buds ) no significant effect . Therefore , it is recommended to strengthen basal and heavy pruning in the early growing season of R.chinensis , to ensure there is enough mineral nutrients to absorb to promote germination and the growth intensity of flowering branch , increasing the number of buds and improve the quality of flowering .
