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 agronomic traits of Trust and Grace, which are domestic import 90 8, Shenfen 4, Puhong 7, Su Hong 1 and the Netherlands, were analyzed in a Dutch double Venlo glass greenhouse. The temperature in the modern greenhouse The impact of tomato growth was studied. The results show that the heating in modern greenhouse can control the daytime and nighttime temperatures of winter in 25 ℃ and 16 ℃, respectively, to ensure the elimination of low temperature disturbance in tomato. However, there were significant differences in the fruit setting rate and yield of tomato varieties at home and abroad, but the difference of growth habit and growth potential was small. Therefore, it is proposed that the breeding of modern greenhouse tomato varieties in our country can only be gradually made competitive with that of foreign counterparts only by making efforts to improve their commerciality and production in the middle and late stages under the conditions of sub-optimal temperature.
