黄瓜采用“四高四低”育苗新法,可使幼苗健壮,抗逆性强,瓜位低,瓜码密,早上市7-10天,增产30%。1.高温浸种、低温贮种。先将黄瓜种子浸入13℃的温水中泡4小时,然后捞出装入布袋,放在5℃的冰箱中冷贮一夜。第2天取出用凉水冲淋,把水晾干后将布袋放入盆内备用。2.高温催芽、低温炼芽。将盆内种子放在30 50℃的高温下催芽,24小时全部出芽。芽拱嘴2小时后降温到20℃炼芽20小时。3.高温催苗、低温
Cucumber using “four high and four low,” a new nursery law, seedlings can be robust, strong resistance, low melon position, melon code dense, morning 7-10 days, an increase of 30%. 1. High temperature soaking, low temperature storage. The first cucumber seed soaked in warm water at 13 ℃ for 4 hours, then remove and put into the bag, placed in a 5 ℃ refrigerator cold storage overnight. 2 days removed with cold water shower, the water bag after drying into the pot reserve. 2. High temperature germination, low temperature refining buds. Put the seeds in the pot at 30 50 ℃ under high temperature germination, all budding 24 hours. Bud arch mouth 2 hours after cooling to 20 ℃ budding 20 hours. 3. High temperature reminder seedlings, low temperature
