上海地区草莓促成栽培正在迅速发展,一般是利用大棚双层塑料薄膜保温。但是由于冬季尤其是在1～2月份日照短、温度低,大棚内经常出现5℃以下的低温,从12月下旬开始随着日照与气温的不足,长势变差、植株矮化,影响草莓的产量和质量。本试验通过比较简易的电照与土壤电加温的方法,研究对草莓生长与产量的影响,探索实际应用价值。试验于1991～1992年在本院园艺所试验地进行。一、材料与方法 (一)材料 1.供试品种:“丰香”与“宝交早生”。 2.主要栽培措施:促成栽培试验地于9月上旬每100m~2全面撒施腐熟猪粪450kg,氮磷钾复合化肥7.5kg。充分翻耕后作畦。草莓苗经过假植育苗,
Strawberry cultivation in Shanghai is rapidly developing, the general use of plastic double-walled greenhouse insulation. However, due to the short sunshine and low temperature in winter, especially in winter and autumn, the low temperature below 5 ℃ often appears in the greenhouse. From late December, with the lack of sunshine and temperature, the growth becomes worse, the plants dwarf and affect the strawberry Yield and quality. In this study, we compared the effects of simple electric lighting and soil electric heating on the growth and yield of strawberry and explored its practical value. The experiment was carried out in our garden experiment from 1991 to 1992. First, materials and methods (a) material 1 test varieties: “abundance of incense” and “Bao Jiaoshengsheng.” 2. The main cultivation measures: to promote cultivation trials in early September every 100m ~ 2 full application of decomposed pig manure 450kg, NPK fertilizer 7.5kg. After full tillage 畦. Strawberry seedlings after planting seedlings,
