每年在牡丹花盛开的时节,都要举行盛大的洛阳牡丹花会。为了解决因春季气温不正常,牡丹花不能如期开放的问题,我们采取了搭塑料棚人工控制棚内、温湿度和光照等措施,达到控制牡丹花期的目的,效果显著。具体方法如下。在3月初,用钢管、钢筋、竹片等材料,搭成拱形或屋脊形骨架,上面覆盖塑料薄膜。塑料棚东西走向,屋面朝南,便于采光。棚的大小视需要而定,高度以不影响牡丹生长发育和便于管理人员往来操作为宜。 Annual Peony blooming season, held a grand Luoyang Peony Fair. In order to solve the problem that the peony flower can not be opened on schedule as a result of abnormal temperature in spring, we have taken the measures of manually controlling the shed, temperature, humidity and light in the plastic shed to achieve the purpose of controlling the peony flowering period, and the effect is remarkable. Specific methods are as follows. In early March, with steel pipe, steel, bamboo and other materials, domed or ridge-shaped skeleton, covered with plastic film. Plastic shed east-west, the roof facing south, easy to light. Shed size as needed, height does not affect the growth and development of peony and facilitate the management of personnel exchanges and operations is appropriate.
