试验表明,“四高四低”变温育黄瓜苗,可以使幼苗健壮,坐瓜密,瓜位低,根系发达,抗逆性强,为早熟高产打下良好基础。其技术要点是: 1.高温浸种,低温贮种先将黄瓜种子浸入13℃的温水中浸4小时,然后捞出装入布袋里,放在一5℃的冰箱中冷贮一夜,第二天取出 Experiments show that the “four high, four low” variable temperature cucumber seedlings can make seedling robust, sit melon dense, low melon, root system developed, strong resistance, lay a good foundation for early maturity and high yield. The technical points are: 1. High temperature soaking seeds, low temperature storage First cucumber seeds immersed in warm water at 13 ℃ for 4 hours, then remove and put into the bag, placed in a refrigerator at 5 ℃ cold storage overnight, the next day take out
