近日,严寒持续,这给大棚蔬菜的生长造成一定的影响。大棚蔬菜防低温的措施如下:清沟培土。要及时清理田内“三沟”和田外渠道,确保排水畅通,提高根系活力。同时,结合清沟,撬沟泥于作物根部,压草保温护苗。保暖防冻。大棚蔬菜可采用地膜、中棚膜、大棚膜分别进行多重覆盖保温防寒,由于中棚与大棚间隔有空气,可明显地提高棚内温度。在播前对种子进行冷冻处理的基础上,幼苗期再进行低温炼苗,以增强植株抗寒能力。对于有条件的大棚尽可能用电热线加温、木炭火炉、小锅炉、燃油风机等补充热量。 Recently, the cold continued, which caused a certain impact on the growth of greenhouse vegetables. Greenhouse vegetable anti-low temperature measures are as follows: Gully soil cultivation. To promptly clean up the Tin “three ditch ” and field channels to ensure that drainage is unblocked, improve root vitality. At the same time, with the Qing ditch, pry ditch mud in the crop roots, pressure grass insulation Miao Miao. Warm antifreeze. Greenhouses vegetables can be used in the film, the greenhouse film, greenhouse film were multi-covered insulation cold, as the shed and the greenhouse air interval, can significantly increase the shed temperature. On the basis of the frozen treatment of seeds before sowing, the seedlings were further subjected to low temperature hardening to enhance the ability of plants to resist cold. As far as possible for the greenhouse with electric heating, charcoal stoves, small boilers, fuel fans and other supplementary heat.
