北美海棠品种在不同栽植模式下的生长和生理响应研究

Study on the Growth and Physiological Responses of Different Planting Patterns of the North American Begonia Varieties

为了探索北美海棠(North American Begonia)对不同栽植模式的响应,提升北美海棠在园林绿化中的栽植广度。研究了6个北美海棠品种在5种栽植模式下的生长和生理响应。结果表明,从不同品种对栽植模式的响应来看,栽植模式1要优于其他栽植方式;其中露易莎对各种栽植方式适应性最好,其次是罗宾逊、凯尔斯、丰花;各北美海棠品种在园林绿化应用中栽植高度以小于地面40 cm为宜;光合特性差异较小的品种有高原之火、丰花、罗宾逊、凯尔斯;高原之火的成活率最高,为100%,其次是凯尔斯、露易莎、丽丝,成活率为80%。凯尔斯、高原之火植株的叶片发病率较低,丰花、丽丝的植株叶片虫害较轻。

In order to explore the response to different planting patterns and improve the planting width in garden greening,the differences of the growth and physiological responses of 6 North American Begonia varieties were studied under 5 planting patterns. The results showed that： In response to the planting patterns of the varieties, planting mode 1 was better than other planting methods to all the 6 North American Begonia varieties. Adaptability of Malus Louisa was best for all kinds of planting patterns, followed by Malus Robinson, Malus Kelsey, Malus Profusion. The North American Begonia varieties plant height to less than 40 cm above the ground was appropriate in garden greening. Photosynthetic characteristics difference was small among the varieties of Malus Prairifire, Malus Profusion, Malus Robinson, Malus Kelsey; Malus Prairifire survival rate was the highest by 100%; followed by Malus Kelsey, Malus Louisa, Malus Liset, the survival rate was 80%. Malus Kelsey, Malus Prairifire plants had low leaf disease incidence rate; to Malus Profusion and Malus Liset, plant leaf insect pest was lighter.
