一、育壮苗小西瓜棚室早熟栽培的育苗,一般在冬寒季节。若无加温条件的棚室,苗床应设在棚室中部且光照最充足的部位,与棚室方向一致,一般做成宽为1.2-1.5米的高畦。为了提高效果可在底部铺设电加热线(70-100瓦/平方米),苗床上架设小拱棚覆膜保温,双层覆盖基本上可以满足温度要求。必要时可在小棚上加盖草毡、无防布保温防寒,如播种期推迟,床底不必铺设电加温线。
First, nurturing young seedlings watermelon nursery precocious cultivation, generally in the winter cold season. If there is no heating conditions of the greenhouse, seedbed should be located in the middle of the greenhouse and the most abundant parts of the light, and the direction of the same greenhouse, generally made of width 1.2-1.5 meters high 畦. In order to improve the effect of electric heating at the bottom of the laying of the line (70-100 W / m), seedbed set up a small arch shed insulation, double coverage can basically meet the temperature requirements. If necessary, can be stamped on the shed in the shed, no anti-cold cloth insulation, such as the sowing delay, the bed does not have to be laying electric heating line.
