1 铺电热线 在温室、阳畦或塑料大棚内铺设电热线加温是冬季育苗和生产蔬菜较有效的措施。特别是苗床铺设电热线,对培育壮苗,达到高产有重要意义。铺设电热线的密度应根据当地气候条件而定,比较寒冷的地区铺的密度可高一些,功率大些;反之功率可小些,以节约用电,一般床内土温保持在10～20℃,每平方米功率可选定100瓦左右,铺线间距10～12厘米,床土厚10厘米
1 shop hotline laying in the greenhouse, sun or plastic greenhouse hotline heating is winter seedling and vegetable production more effective measures. In particular, laying hotbed seedbed, nurturing strong seedlings, to achieve high yield is of great significance. The density of the laying of hotline should be based on local climatic conditions, shop in the more cold areas of the density may be higher, higher power; Conversely the power may be smaller, in order to save electricity, the general soil temperature in the bed at 10 ~ 20 ℃ , The power per square meter can be selected about 100 watts, laying spacing of 10 to 12 cm, bed soil thickness of 10 cm
