11月份定植的大棚黄瓜在山东、辽宁等地已经栽培成功。但深冬大棚黄瓜的浇水是一项极其严格的技术,若掌握不好,降低了地温,会使栽培失败。掌握好浇水技术的要点是: 1.浇足定植水,覆盖地膜保温。定植前,开沟或开穴浇透水,然后盖地膜及大棚膜升温。2～3天后带坨移栽,并浇水浸透土坨,水渗后封闭,盖严地膜。 2.2月中旬前的3个月内,严格控水,尽量不浇水。这期间是栽培成败的关键时期,各种保护措施用来维持气温,一旦浇水降低了地温,则很难回升,严重影响黄瓜根系的活动。因此,这段时间控制不浇水是保持地温的有效办法。山东苍山县的经验是尽量不
November cucumber planting greenhouses in Shandong, Liaoning and other places have been cultivated successfully. But the winter greenhouse cucumber watering is an extremely strict technology, if not mastered, reducing the ground temperature, will make the cultivation fails. Grasp the key points of watering technology are: 1. Pouring foot planting water, covering the film insulation. Before planting, ditching or open hole watering, and then cover the film and greenhouse film warming. After 2 ~ 3 days with lump transplanting, and water soaking soil Tuo, after the water seepage closed, cover Yan film. 2. 2 months before mid-3 months, strict water control, try not to watering. During this period is the key to the success or failure of cultivation, a variety of protective measures to maintain the temperature, once the water reduces the ground temperature, it is difficult to pick up, seriously affecting the activities of cucumber roots. Therefore, this period of time to control watering is an effective way to maintain ground temperature. Cangshan County, Shandong experience is as far as possible not
