茄果类生产50—60年代采用火窖与薄膜保温育春苗,到70年代推广薄膜保温育冬苗收到一定成效,但由于保温性能差,湿度大,病害严重,成苗率低,往往不能保证大面积生产用苗。随着郊区塑料大棚生产的发展,我们于1978年冬试验大棚(面积1.72亩)育茄果类冬苗成功。
Solanaceous fruit production 50-60 years using fire cellar and thin film insulation spring seedlings, to the 1970s to promote the film insulation winter seedlings have received some success, but due to poor insulation properties, humidity, serious disease, low seedling rate, often Can not guarantee large-scale production with seedlings. With the development of the production of plastic sheds in the suburbs, we succeeded in testing the greenhouse of winter 1978 (covering an area of 1.72 mu) and winter tomato seedlings.
