蔬菜大棚育苗,以培育适龄壮苗为目标,具有抗逆性强,素质高的菜苗,为高产稳产打下良好基础。经过1986年冬至1988年春两个冬、春的生产试验,我们总结了蔬菜大棚育苗的经验教训,重点应抓好以下几项技术措施。 1.掌握适宜温度:防止冷害、热害,番茄、甜椒自播种到出土,一般需5～7天时间,未经催芽的甜椒需要两星期。齐苗后各自要求的适宜温度分别为:日间,番茄20～25℃,甜椒25～30℃;夜间,番笳13～15℃,甜椒18～20℃。2月30日前重点应放在防冷害上,零度以下就有受冻的危险。
Vegetable greenhouse nursery, nurturing age-appropriate seedlings as the goal, with strong resistance, high quality vegetable seedlings, lay a good foundation for high and stable yield. After 1986 winter to 1988 spring two winter, spring production test, we summed up the vegetable shed nursery experience and lessons should focus on the following several technical measures. 1. Grasp the appropriate temperature: to prevent chilling damage, heat damage, tomatoes, sweet peppers from sowing to unearthed, usually takes 5 to 7 days, without the need for two weeks of germination bell peppers. Qi Miao after the respective requirements of the appropriate temperature were: day, tomato 20 ~ 25 ℃, sweet pepper 25 ~ 30 ℃; night, Fanfan 13 ~ 15 ℃, sweet pepper 18 ~ 20 ℃. Prior to February 30 should focus on anti-chilling damage, there is danger of freezing below zero.
