合作908超大果粉红番茄,双亲均由美国引进,经长征良种实验场选育后,组配而成的新F_1代杂交组合。 一、特点 中早熟,高封顶,抗病性、抗逆性强,大果型,平均单果重达300g以上,最大果可达800g。果色粉红鲜艳,高圆球型,多心室,果肉厚,品味好,商品性极佳,耐贮藏和运输,是大棚生产及露地栽培、外调蔬菜栽培理想品种。 二、特性株高100cm至120cm,7片叶簇生第1花序,以后每隔3片叶簇生花序,具有侧枝少,管理容易,生长势旺盛,采收期较长等优点。 三、栽培要点 要适时播种,培育壮苗,一般苗龄在85天左右,早春育苗遇低温后,影响花芽分化,会出现畸形果。定植前,施足基肥,以农家有机肥和氮磷钾复合肥配合使用,早期坐果,激素浓度不宜过高,防止出现裂果现象,第1花序果一般应留2至3个为好,坐果后,要加强肥水管理,保持土壤适宜干湿度,使植株正常生长发育,并且做好防病除虫工作。该番茄品种春秋二季都能栽培,秋季栽培同样表现抗病高产,果实商品性更佳,在长江流域秋季栽培应考虑到苗龄不宜过长（不超过25天）,应在适宜的播种期播种。
Cooperation 908 large fruit pink tomato, parents were introduced by the United States, the Long March breeding field breeding, the combination of the new F_1 hybrid combinations. First, the characteristics of premature, high cap, disease resistance, strong resistance, large fruit, the average weight of more than 300g, the largest fruit up to 800g. Fruit pink bright, high ball type, multi-ventricular, thick flesh, good taste, good product, storage and transportation, is the production of greenhouse and open field cultivation, the ideal of cultivation of vegetables outside varieties. Second, the characteristics of plant height of 100cm to 120cm, 7 leaf clusters of the first inflorescence, after every three leaves clustered inflorescences, with less collateral, easy management, vigorous growth potential, harvesting longer and so on. Third, the main points of cultivation should be timely sowing, nurturing strong seedlings, the general seedling age of about 85 days, early spring nursery encounter low temperature, affecting flower bud differentiation, there will be deformed fruit. Before planting, apply enough base fertilizer to farm organic manure and NPK compound with the use of early fruit set, the hormone concentration should not be too high, to prevent the phenomenon of split fruit, the first inflorescence should generally stay 2 to 3 as well, after fruit set , We should strengthen fertilizer and water management, to maintain the soil suitable for dry and humidity, so that plants grow normally, and do a good job in disease prevention and pest control. The tomato varieties can be cultivated in spring and autumn, the autumn cultivation also showed disease-resistant and high-yield, fruit commodity better, should be taken into account in the autumn of the Yangtze River valley seedling age should not be too long (not more than 25 days) should be sown in the appropriate seeding .
