黄淮海地区日光温室秋延后番茄品种筛选试验

为了筛选适合黄淮海地区日光温室秋延后栽培的番茄品种,以6个番茄新品种为试材,以当地栽培较多的粉之星为对照,对参试各品种的植物学性状、结实性、抗病性和丰产性进行比较分析。结果表明,瑞粉882、爱吉112、欧粉308比对照品种粉之星植株生长势壮,且叶色深绿;株高、茎粗分别比对照高3.09%~1.14%、13.04%~18.26%;结实性方面也显著优于对照品种,表现为果实单果质量大(280~310 g),果实高圆型,商品性好,果实硬度高;抗病性强,其中TY病毒病、早疫病、晚疫病、灰霉病、灰叶斑病发病株率明显比对照低;3个品种的产量分别比对照增产34.8%、30.4%、26.1%。综上所述,瑞粉882、爱吉112、欧粉308综合表现为丰产、抗病、结实性好,是适合黄淮海地区日光温室秋延后栽培的理想品种。

Comparison Experiment of Late Autumn Tomato Varieties in Greenhouse in Huang-huai-hai Region

In order to select tomato varieties for late autumn cultivation in greenhouse in the Huang-huai-hai region,with six new tomato varieties as experimental materials,Fenzhixing planted more locally as the reference,the botany traits, fruitfulness, disease resistance and high yielding of different varieties were compared and analyzed. The results showed that the varieties Ruifen 882,Aiji 112,and Oufen 308 plants grew stronger than the control,with dark green leaves. The plant height increased by 3. 09%—1. 14%, and the stem width increased by 13 . 04%—18 . 26%. The fruitfulness was significantly better than the contrast,with high round fruit,good shelf quality,higher fruit hardness and larger fruit quality of 280—310 g. The varieties showed strong disease resistance,the disease rates of TY virus disease,early blight, late blight,mould,gray leaf spot significantly reduced. The yields of the three varieties were 34. 8%, 30. 4% and 26. 1% respectively higher than the control. Above all,Ruifen 882,Aiji 112,and Oufen 308 have comprehensive performance of high yield,disease resistance,and good fruitfulness,which are ideal varieties suitable for late autumn cultivation in sunlight greenhouses of the Huang-huai-hai region.
