果桑大棚不同覆膜时间的试验与探讨

Investigation on Different Film Covering Time in Mulberry Fruit Greenhouse

通过多年在永康市丽星农庄的试验调查,在永康地区的气候条件下,单层薄膜果桑大棚的封棚保温时间以1月20日左右为宜,同时封棚保温时间还要根据节日及劳动力状况灵活掌握。果桑大棚内目标温度可以分2个阶段掌握,花期阶段的温度控制在30℃左右,座果后阶段的温度控制在35℃左右。大棚侧膜开启、关闭的时间和大小,要根据户外气温高低、阳光强弱、风力大小来灵活掌握。

It was found that the suitable closing time for single-layer film mulberry fruit greenhouse is about January 20 through many years of experimental investigation in Lixing Farm of Yongkang City under the climatic conditions of Yongkang area,and the time for greenhouse insulation should be flexibly controlled according to festivals and labor conditions. The target temperature in mulberry fruit greenhouse can be controlled in two stages:that is,the temperature in flowering stage can be controlled at about 30 ℃,and the temperature in post-fruit stage can be controlled at about35 ℃. The opening and closing time and size of side film in greenhouse should be flexibly controlled according to outdoor temperature,sunshine and wind.
