为了获取大棚黄瓜的早熟、高产,近年来我们采取了八项增产措施,效果较好。 多层覆盖:即在大棚下面增加一层天幕,天幕下面扣小棚,地面进行地膜覆盖。棚的四周内加一层塑料薄膜围裙,外加一层草苫覆盖。此外,再辅之以炉火、电热线、暖气、热风等任何一种临时加温设备。这样可提前使地表下10厘米地温稳定在10℃以上,比一般大棚早定植10～30天。后期,这些多层覆盖材料可移到春、夏菜使用。在管理中白天揭开天幕和小拱棚,晚上再盖上,其他管理照常。
In order to obtain greenhouse cucumbers early, high yield, in recent years we have adopted eight stimulation measures, the effect is better. Multi-layer coverage: that is, adding a layer of canopy below the greenhouse, canopy buckle under the canopy, the ground mulching. Add a layer of plastic film apron around the shed, plus a layer of grass cover. In addition, supplemented by a fire, hotline, heating, hot air and any kind of temporary heating equipment. This can make the surface temperature below 10 centimeter in advance stable at 10 ℃, 10 to 30 days earlier than the general planting greenhouses. Later, these multi-layer cover material can be moved to spring and summer vegetables. In the management of the canopy and shed during the day and then covered at night, the other management as usual.
