摘要
利用加温线和发热膜进行了冬季黄瓜育苗和栽培试验。结果表明,温控相同条件下,加温线的耗电量大于发热膜,发热膜苗床上的基质温度首先达到温控最高点,且一天中变化幅度较平稳。发热膜苗床上春秋王、沪杂3号、沪杂6号黄瓜品种幼苗的下胚轴长、子叶长和宽都大于加温线苗床上的幼苗。定植后的3个处理中,植株叶长、叶宽、叶片数、株高和单株产量表现为发热膜处理>发热膜+小环棚处理>加温线处理。因此利用发热膜进行冬季茄果类育苗,不仅省电而且加热能力和保温效果好。
The heating wire and heating films were used to grow cucumber seedling and plants in winter. Under the same of temperature controller,the electricity consumption of heating wire was more than that of heating film, the temperature of nursery bed first reached the set point and stayed more stable with heating film. The hypocotyl length and cotyledon size of 3 cucumber varieties grown with heating film were greater than those grown with heating wire. The leaf length, leaf width, and leaf number, plant height and yield per plant of the cucumber seedling grown with heating films were the best after transplant. Therefore, heating film is recommended for seedling nroduction during winter season.
