一、增设反光幕。在温室北侧设反光幕,增强室内弱光区光照;可提高地温1～2℃,能增产5％以上。 二、膜下滴灌。在温室内两行黄瓜行间地膜下设置一条带有孔的塑料管作为毛管,灌溉水从毛管上的孔眼上滴出,形成膜下管孔式局部微量滴灌。这样膜下灌溉只增加 First, the addition of reflective screen. Set in the north of the greenhouse light curtain to enhance the indoor light weak light; can increase the ground temperature 1 ~ 2 ℃, can increase yield 5%. Second, drip irrigation. In the greenhouse, cucumber between two rows of lines to set a plastic tube with holes as a capillary, irrigation water dripping from the hole on the capillary tube to form a film under the tube-hole local drip irrigation. This way the irrigation under the membrane only increases
