本试验以常规冷床育苗为对照,对电热温床育苗的苗床温度效应、出苗数、幼苗生长发育速度和整齐度、幼苗生育期及经济效果进行了比较分析。结果表明:电热温床育苗能显著增加苗床地温和气温,并保持苗床地温比较平稳,造成地温高于气温的环境,较好地满足了幼苗生育的温度条件,使瓜果类蔬菜播种后出苗快而齐,幼苗生长发育快而一致,幼苗根系发达、茎叶健壮、为丰产奠定了基础。定植后的电温幼苗生育迅速,产品上市比冷床苗提早7—21天,增加产量26.8—27.4%,增加纯收入24.0—43.0%。
In this experiment, the conventional cold bed nursery as a control, hot temperature hotbed nursery seedbed temperature effects, number of emergence, seedling growth and development and uniformity, seedling growth period and economic effects were compared. The results showed that the electric hotbed nursery can significantly increase the temperature of the seedling bed, and keep the ground temperature relatively stable, resulting in the temperature is higher than the temperature environment, better meet the temperature conditions of seedling growth, so that fruits and vegetables quickly sown after sowing Qi, rapid growth and development of seedlings coincide, developed seedling roots, stems robust, laid the foundation for high yield. After the planting, the electric seedlings grow quickly and the products are listed 7-21 days earlier than the cold bed seedlings, increasing the output by 26.8-27.4% and increasing the net income by 24.0-43.0%.
