蔬菜塑料温室电加温线育苗,是陕西地区正在推广的一种蔬菜育苗新形式。通过试验表明:①在西安地区采用塑料温室电加温线育苗,室内必须有小拱棚覆盖,才能有效地保证各种菜苗所需的地温和气温。小拱棚的保温性能:农用无纺布与塑料薄膜比较,夜温可提高3.7℃,地温可提高11℃。②在塑料温室电加温育苗中,由于蔬菜种类不同,耗电量也不同:番茄耗电量最少,每平方米总耗电量为7度;黄瓜次之,每平方米总耗电量为14度;茄子、辣椒最多,每平方米总耗电量为27度。③塑料温室电加温线育苗,与常用的温室炉灶加温育苗、阳畦电加温线苗以及玻璃温室架式育苗相比,其苗子质量虽然差异不显著,而它的投资和经济效益却优于这三种形势。
Vegetable plastic greenhouse electric heating line nursery, Shaanxi is promoting a new form of vegetable nursery. Experiments show that: ① in Xi’an plastic greenhouse electric heating line nursery, indoor must be covered with a small arch, in order to effectively ensure that all kinds of vegetable seedlings required temperature and temperature. Small shed insulation performance: Agricultural non-woven fabric and plastic film compared to night temperature can be increased by 3.7 ℃, ground temperature can be increased by 11 ℃. ② in the plastic greenhouse electric heating nursery, due to different types of vegetables, power consumption is also different: tomato power consumption at least per square meter total power consumption of 7 degrees; cucumber second, the total power consumption per square meter of 14 degrees; eggplant, peppers up to a total power consumption of 27 degrees per square meter. ③ plastic greenhouses electric heating line nursery, and commonly used greenhouse stove heating nursery, electric heating Yangguang line and glass greenhouse-style nursery seedlings, although the difference is not significant, but its investment and economic benefits In these three situations.
