Studies on the Technique of Celery Safety Living through the Winter Covered with Multilateral Materials in Plastic Canopy

在塑料大棚内,对西芹多层覆盖安全越冬技术进行了研究。结果表明:多层覆盖可明显提高冬季塑料大棚内的地温和气温,西芹收获早和效益高。该技术使大棚西芹冬季安全生产成为可能。

The technique of celery safety living through the winter covered with multilateral materials in plastic canopy was studied. The results showed that the atmospheric temperature and soil temperature could be improved obviously by covering with multilateral materials in the plastic canopy. The celery could be harvested earlier in early spring and got higher economical efficiency. It was possible that celery could be produced safely in plastic canopy in winter.
