一、选择品种应选择中早熟、抗病又丰产的品种。如特选津研4号、津研5号、津研6号、津春4号、夏丰1号等。二、培育壮苗露地春黄瓜定植的生理苗龄为4叶1心,日历苗龄为35-40天。北方大部分在3月份于阳畦内育苗,主要是通过揭盖草苫和通风管理来控制温度。1、苗床管理。在发芽出土期要封好膜,不放风,白天利用阳光提高畦温,促进发芽出土,白天25-30℃,夜间15-20℃,因此,上 First, choose varieties should be selected in the premature, disease-resistant and high yield varieties. Such as selected Jin research on the 4th, Jin research on the 5th, Jin research on the 6th, Jinchun on the 4th, Xia Feng on the 1st and so on. Second, nurturing seedlings planted spring cucumber planting physiological seedling age 4 leaves 1 heart, calendar seedling age of 35-40 days. Most of northern nurseries were raised in the Yanggu clan in March, mainly through the control of grass coverings and ventilation to control temperature. 1, seedbed management. In the period of germination unearthed to seal the membrane, do not let the wind, the use of sunlight during the day to raise the temperature, promote germination unearthed during the day 25-30 ℃, night 15-20 ℃, therefore, on the
