开原县老城扶余三队技术员采用“三高三低”变温育苗法,育出了壮苗,配合综合措施,获得了日光薄膜温室黄瓜亩产3万2千斤的收成.高温催芽,低温炼芽.种子浸泡后,在30～35℃高温下催芽,经24小时可以全部出芽.芽拱咀两小时后,降温至20℃炼芽,出芽整齐粗壮.高温催苗,低温蹲苗.播种前室温40℃,床土浇开水,待土温降至40℃时,抢温播种已经催芽的种子,
Kaiyuan County, the old city of Fuyu three teams of technicians using the “three highs and three low” variable temperature nursery method, nurtured a strong seedlings, with comprehensive measures to obtain sunlight thin film greenhouse cucumber yield 3200 kg per mu. High temperature germination, low temperature refining bud Seed soaking, germination at 30 ~ 35 ℃ high temperature, can be all budding after 24 hours bud bud Tsui two hours later, cooling to 20 ℃ budding, budding neat stout. High temperature reminder vaccine, low temperature squat seedlings before sowing at room temperature 40 ℃, bed soil pouring boiled water, until the soil temperature dropped to 40 ℃, seize the warm seeding seeds have been germination,
