不同温度和光照对紫叶酢浆草生长的影响

[目的]研究不同温度和光照条件下紫叶酢浆草的生长情况。[方法]选取3、6、9月和0、25%、50%、75%4个遮阴度环境下的紫叶酢浆草鳞芽进行交叉试验,形成12个处理区,30 d后调查紫叶酢浆草叶柄长度,第二年观察花期、开花量、叶色以及病虫害情况。[结果]春、秋季紫叶酢浆草生长最快;温度对紫叶酢浆草生长影响较大但对其花期影响不大;光照对紫叶酢浆草的花量和叶色影响较大,当遮阴率25%时对紫叶酢浆草生长最为有利;在高温条件下紫叶酢浆草易发生叶斑病和红蜘蛛危害,强烈阴蔽条件下易发生蚜虫和蜗牛危害。[结论]温度22℃、遮阴率25%是紫叶酢浆草生长的最佳环境。

Effect of the Different Temperature and Light on the Purple Oxalis Growth

[Objective] The growth and development of oxalis were researched.[Method] The bus scale of purple oxalis at age of three,six or nine months and under the shed condition of 1%,25%,50% or 75%,respectively,being taken as experimental material,the length of petiole after 30 days,the flowering period,the amount of flower,the color of leaf and pest/disease occurrence in next year were investigated.[Results] The fastest growth of oxalis appeared in spring and autumn season.The temperature greatly affected the growth of oxalis but its flowering period.The light had the great effect on the amount of flower,the color of leaf of oxalis and under the shed condition of 25% the oxalis grew very well.Under the condition of high temperature,the damage of leaf spot and red spider easily appeared in the plant and the intensive shed condition would result in the aphids and snail occurrence in the plant.[Conclusion] The best condition for the oxalis growth was the temperature was 22 ℃ and the shed condition was 25%.
