摘要：【目的】研究不同土壤改良剂对月季花朵品质的影响，为高品质月季的栽培提供理论和技术支持。【方法】对地栽、盆栽两种不同栽培方式的月季施入不同种类、不同用量的土壤改良剂，每隔1d对月季植株生长情况进行观察，并记录月季植株分枝数、花枝长度、花径、花瓣数和单朵花重等，观察周期为一个完整的生长周期。【结果】在地栽月季栽培中，采用全奉德华土壤改良剂可以增长花枝长度，采用誉中奥土壤改良剂可以有效增大花朵的直径；在盆栽月季中，添加一定质量的全奉德华土壤改良剂和誉中奥土壤改良剂有利于月季分枝数、花瓣数增加及花径的增大，有利于花品质的改善，适宜的施用量为0.64kg/盆。【结论】土壤改良对月季花朵品质具有一定的改善作用。

Abstract：【Objective】Effects of different soil amendments on quality of rosa chinensis were studied in order to provide theoretical and technical support for the cultivation of R.chinensis.【Method】Soil amendments of different kinds and application rates were applied to R.chinensis seedlings planted on ground and in pot.he growth situation of the R.chinensis seedlings was observed every 1 d and branch number， length of flowering branch， flower diameter， number of petal， weight of single flower were recorded.he observation cycle was a complete growth cycle.【Result】For R.chinensis seedlings planted on ground， Quanfengdehua soil amendment could increase the length of branches， Yuzhongao could effectively increase the diameter of the flower.For potted R.chinensis seedlings， adding a certain amount of Quanfengdehua and Yuzhongao soil amendment was conducive to increasing branch number， petal number and flower diameter， which could improve the flower quality.he appropriate application rate was 0.64 kg/ pot.【Conclusion】Soil amendments can improve the quality of R.chinensis to certain extent.

月季（Rosa chinensis）隶属蔷薇科蔷薇属，多年生落叶或常绿灌木，具有极高的观赏价值，是大众喜爱的鲜切花。月季一年可连续多次开花，产花量高，但需肥量大。在传统的切花生产中，随着种植年限的增加，长时间的連作及长期单一施用化肥会造成土壤盐碱化、板结，影响月季根部的透气性[1]，从而降低切花的品质和产量，对月季生产发展产生不良影响。因此，研究土壤改良对月季生长的影响，尤其是对花品质的影响具有重要的生产指导意义。

近年来，对月季的土壤改良研究逐渐增多，多数研究是通过施肥来实施[2-4]。……
