1.大棚构建为预防大雪压垮大棚,有条件的可建钢筋和混凝土骨架大棚,采用竹木、塑料构架的要保证强度,尽量采用拱形结构增强支撑力,棚顶要有坡度,以避免积雪。2.降雪前注意检查棚膜破损、棚架坚固、棚口保温、压膜线紧固等情况,并及时维修。采取保温措施,防止蔬菜作物受冻,可提早采收。控制浇水和追肥,以降低湿度,避免旺长。如是喜温蔬菜,可多加一层棚膜或搭小拱棚;如降温较多,育苗大棚除外
1. Greenhouses constructed to prevent snow from collapsing greenhouses, the conditions can be built steel and concrete skeleton greenhouse, the use of bamboo, plastic framework to ensure strength, as far as possible using arch-shaped structure to enhance the support force, the roof slope to have to avoid snow. 2. Check the damage before falling snow film shed, scaffolding sturdy shed insulation, film line fastening and other timely maintenance. Insulation measures taken to prevent the freezing of vegetable crops can be harvested early. Control watering and top dressing to reduce humidity and avoid blooming. If the temperature of vegetables, you can add a layer of film or take small Shed; such as cooling more, except nursery greenhouse
