恰当选择种苗催花种苗的品质是关键因素之一这里包括品种和质量两个方面。牡丹品种很多,但并非个个都适宜催花,据经验,容易催花并具良好效果的品种并不太多,有‘朱砂垒’、‘赵粉’、‘胡红’、‘紫二乔’、‘肉芙蓉’、‘银红巧对’、‘藏枝红’等。一般选择健壮的4～5年生植株,株型紧凑,有粗壮枝干5～8枝,分布匀称,芽体饱满充实,根系强健发达。打破休眠在自然生长情况下,牡丹要经过了冬季低温期才能在来年春季顺利萌芽。因此催花过程中,前期的低温对解除休眠十分重要。用于春节供花的植株,上盆时正处于头年11月或12月,已过了一段时间的自然低温,一般可直接催花;若想在元旦或圣诞节供花,则必须经过人工低温处理(0～5℃下处理5～7周)后
Appropriate choice of seedlings Promote the quality of seedlings is one of the key factors here, including variety and quality of two aspects. There are many varieties of peony, but not all of them are suitable for urging. According to experience, there are not many varieties that are easy to flower and have good effects. There are many varieties of peony, such as’ Cinnabar, ’’ Zhao Fen, ’,’ Meat hibiscus’, ’silver red coincidence’, ’Tibetan red branches’ and so on. Generally choose robust 4 to 5-year-old plants, compact plant type, with thick branches 5 to 8, well-distributed, bud full enrichment, robust root developed. Break dormancy In the case of natural growth, peony to go through the winter low-temperature period in order to successfully sprout in the spring of next year. Therefore, the process of urging, pre-low temperature on the release of sleep is very important. For the Spring Festival flowers for the plants, the basin is in the first year in November or December, after a period of natural low temperature, the general can be direct reminder flowers; if you want to New Year’s Day or Christmas flowers, you must go through artificial low temperature treatment (5 ~ 7 weeks after treatment at 0 ~ 5 ℃)
