中文摘要:

      为研究多花酢浆草与红花酢浆草在北京地区的生长适应性，采用一系列栽培繁殖措施对两种酢浆草进行研究。试验结果表明:多花酢浆草和红花酢浆草生长期是4-11月，花期是5-10月，低于0℃植株地上部分死亡，冬季露地越冬要用覆盖物或是把球茎挖掘放入大棚；高温对多花酢浆草和红花酢浆草生长不利，减缓植物的生长。多花酢浆草最佳栽植时期是7月，红花酢浆草是4月。这两种酢浆草最适合种植在沙土上，其次是黄土+沙土。8-9月份适合施磷钾肥，延长花期，10月适合施氮肥，促进植物生长。最常见的虫害是红蜘蛛，适于用强内吸性杀虫剂如阿维菌素及时全面喷施防治。

英文摘要:

      In order to study the growth and adaptive cultivation of Oxalis corymbosa DC and Oxalis Martiana Zucc in Beijing area, a series of cultivation and propagation measures were used for these two species. The experimental results show that the growth period of Oxalis corymbosa DC and Oxalis Martiana Zucc is from April to November, their flowering period from May to October. The ground parts of the plant will be dead under 0 ℃ , so in winter, the exposed parts must be covered with mulch, or the carmus needs to put into a shed. The high temperature is unfavorable to the growth of Oxalis corymbosa DC and Oxalis Martiana Zucc, slowing their growth rates. The best planting period of Oxalis corymbosa DC is in July, and Oxalis Martiana Zucc in April. These two kinds of Oxalis are most suitable for planting on sandy soil, secondly on loess and sandy soil. For prolonging the flowering period, it should apply phosphorus and potassium fertilizer in September; for promoting plant growth, it should apply nitrogen fertilizer in October. For the Oxalis , the most common pest is the red spider. It is suitable for timely and comprehensive spraying with strong endo-suction insecticides such as abamectin.
