摘要: 通过观测、考察,小型拱棚在春前加强保温,秋后提早盖苫蓄热是目前提高内部气温和土壤温度、延长应用时期的主要方法。由于受生产条件的限制,常因覆盖物遮阳在北侧形成弱光带,这是亟待改进的问题。

关键词: 小型拱棚, 温度, 光照强度

Abstract: By investigating, we think that enhancing heat preservation before spring and storing heat by covering straw mat earlier than normal time are main ways to raise air and earth temperature in plastic tunnel and to prolong its service life. The cover material brings about weak light area on the north side of the plastic tunnel as a result of the current worse condition. Demanding prompt solution is an important problem.

Key words: Plastic tunnel, Temperature, Illumination
