中国南方芍药露天栽培适应性及其表现初探

Preliminary study on adaptation and performance of Herbaceous peony(Paeonia L.) open-cultivated in South China

选取大富贵、莲台、杨妃出浴3个芍药品种,在广东和湖南两省纬度、海拔不同的7个地点分别开展露天栽培比较试验。通过观察测定芍药的栽培适应性和植株生长发育等各项指标,结合气象资料分析表明,广东春季的温暖高湿气候不仅导致花芽败育、显著降低成花率,也容易引起芍药病害。温度对芍药营养生长有显著影响,但不同品种的适应性表现出一定的差异,其中莲台的适应性最好。

Three Herbaceous peony（Paeonia L.） cultivars,including Dafugui,Liantai and Yangfei Chuyu,were planted outdoor to investigate their performance in seven locations at different latitudes and altitudes in Guangdong and Hunan province.Through comparison of plant adaptability,vegetative growth,flower development and the meteorological data,it was showed that the warm temperature and higher humidity in the spring of Guangdong not only caused flower bud abortion,but also reduced flower number significantly.Meanwhile,the plants were venerable to disease under such climate conditions.The vegetative growth of Herbaceous peony was significantly influenced by temperature,but the adaptability of plants was cultivar dependent,and Liantai performed the best.
