随着蔬菜育苗技术改革的进展,为了解决架盘集中育原苗后,如何提高分苗后的管理水平问题,我们于1982年开始进行分苗后上通风的炼苗试验,收到了较好的效果。采用上通风降温炼苗,在做营养坨或营养土划沟等方面与正常分苗均相同,不同之处就是将分苗后的冷床改为顶部放风。具体做法是在冷床上面用两块1.5米宽的塑料薄膜覆盖.在冷床上面的中部,分别将两块薄膜每隔1米长扎一个结,并用绳绑好,绳的另一端系棍插在
With the progress of vegetable seedling technology reform, in order to solve the problem of how to raise the level of management after the emergence of seedlings and how to raise the level of management after the seedlings, we started the seedling raising experiment after the seedlings were ventilated in 1982 and received the better effect. Adoption of ventilation and cooling Harvest Miao, nutrient trowel or nutrition in the ditch and other areas are the same with the normal sub-seedlings, the difference is that the sub-seedlings after the cold bed to the top of the wind. The concrete method is to use two 1.5-meter-wide plastic film covers on the cooling bed.At the middle of the cooling bed, separate two films every 1m long and tie them together with a rope, the other end of the rope is a stick Plug in
