(三) 温度的管理和控制温度是切花月季生产中一个非常重要的条件,它直接影响切花的产量和品质。比如修剪后出芽的多少、花芽的分化、封顶条的多少、产花的天数、花枝的长度以及花瓣数、花型和花色等等。 1.花芽的分化修剪后枝条上的芽有以下几种可能——(1)休眠芽:生长激素和营养条件都非常差,腋芽不生长。(2)莲座状芽:生长激素和营养条件较差,腋芽长出后,枝生长不高而呈莲座状。(3)封顶条:生长激素和营养条件稍差,出芽后激素水平稍差,花芽分化中途停止,花芽枯死,不开花。(4)开花枝:生长激素和营养水平良好,着蕾开花。当然,是否形成开花枝
(C) temperature management and control Temperature is a very important condition for cut rose production, it directly affects the cut flower production and quality. Such as the number of pruning after budding, the differentiation of flower buds, cap the number of days, the number of days to produce flowers, the length of flowering branches and the number of petals, flowers and colors and so on. 1 flower bud differentiation After pruning shoots on the following possibilities - (1) dormant buds: growth hormone and nutritional conditions are very poor, axillary buds do not grow. (2) rosette buds: poor growth hormone and nutritional status, axillary buds grow, the growth is not high and rosette seat. (3) Ceiling: growth hormone and nutritional conditions slightly less, less hormone level after budding, flower bud differentiation halted, flower buds wither, not flowering. (4) flowering branches: growth hormone and nutrient levels are good, bud blossom. Of course, whether the formation of flowering branches
