现代化温室中部分国内外番茄品种主要农艺性状的差异研究

RESEARCH OF THE MAIN AGRICULTURAL CHARACTERS OF NATIONAL AND IMPORTED TOMATO VARIETIES UNDER THE ENVIRONMENT OF MODERN GLASS GREENHOUSE

在荷兰产双Venlo型玻璃温室中对国内合作 90 8、申粉 4号、浦红 7号、苏红 1号和荷兰进口品种Trust和Grace主要农艺性状进行了分析 ,并就现代化温室中的温度对番茄生育的影响进行了研究。结果表明现代化温室通过加温措施 ,能使冬季昼夜间温度分别控制在 2 5℃和 16℃以上 ,确保基本消除番茄低温障碍。但国内外番茄品种在不同阶段坐果率和产量存在明显的差异 ,而生长习性和生长势差异较小。由此提出我国现代化温室番茄品种的选育 ,只有努力提高其在亚适温条件下的商品性和中后期产量 ,才能使其逐步具备与国外同类品种的竞争力。

The main agricultural characters of national tomato varieties Hezuo 908, Shenfen No.4, Puhong No.7, Suhong No.1 and imported tomato varieties Trust and Grace were identified and analyzed under the environment of modern Venlo type glass greenhouse imported form Netherlands. The effect of the temperature on the growth and fruiting of tomato was also studied. The results showed that temperature in modern greenhouse can be controlled around 25℃ at day time and 16℃ at night, and such temperature is suitable for the growth and development of tomato during whole growth period without obstacles under low temperature. There is no difference in growth behaviour and growth vigor between national and imported varieties, but difference in fruit setting rate and yield at different stage is obvious among different varieties. Compared with imported varieties, it is necessary to improve the fruit commercial characters under relative low temperature and the yield of middie and late stage of national tomato varieties.
