牡丹以黄河中、下游为主要栽培中心,在黑龙江栽培,其生长发育特点表现为春季4月上、中旬开始萌动,花蕾开始发育,5月末至6月中旬开花,7～8月花芽分化,9～10月份的秋季再发新根,10下旬落叶进入冬季休眠。牡丹进入休眠后,需要通过最低温度在零下28℃～30℃的寒冷冬季,有时甚至更低的温度;因此,高寒地区栽培牡丹,如何从技术上解决好牡丹安全越冬问题,使之越冬后生长发育健壮,花朵硕大,颜色鲜艳,花期延长,达到最佳的观赏时期和效果显得尤为重要。笔者经过多年的牡丹露地越冬防寒栽培引种试验并取得了成功。本文总结了栽培技术。
The middle and lower reaches of the Yellow River as the main cultivation center, the cultivation of peony in Heilongjiang Province, the growth and development of the performance of the spring in April, the beginning of germination, bud development, from late May to mid June blossom, 7 to August flower bud differentiation, 9 ~ October new roots again in autumn, 10 late into the winter dormancy leaves. After the peony enters dormancy, it needs to pass the cold winter with a minimum temperature of minus 28 ℃ ~ 30 ℃ and sometimes even lower temperature. Therefore, how to technically solve the problem of overwintering winter peony after peony cultivation in the alpine region? Sturdy development, huge flowers, bright colors, flowering extended to achieve the best viewing period and the effect is particularly important. After many years of peony open-air cold-proof winter planting introduction test and achieved success. This article summarizes the cultivation techniques.
