摘　　要：以不同番茄品种‘NB007’、‘金棚95-2’、‘金棚8B’、‘瑞星大宝’、‘冠粉8号’、‘金山511’、‘普罗旺斯’为试验材料,研究了低温处理对不同番茄品种定植前秧苗生长状况,定植后植株成活率、生长量、产量等的影响。结果表明:低温处理可显著降低幼苗株高,降幅为12%~40%,显著增加幼苗根部鲜质量和定植后成活率,增幅分别为27%~120%,51%~100%。低温处理的番茄品种‘瑞星大宝’、‘冠粉8号’、‘金山511’、‘普罗旺斯’小区产量显著高于‘NB007’、‘金棚95-2’、‘金棚8B’,‘NB007’、‘金棚8B’裂果率较高,为16%~22%,‘金棚8B’、‘金棚95-2’畸形果率为0.8%~5.3%。综合幼苗生长情况、成活率、产量等指标,建议早春大棚番茄定植前进行低温处理,可选种‘瑞星大宝’、‘冠粉8号’、‘金山511’、‘普罗旺斯’等品种。Different tomato varieties of'NB007','Jinpeng 95-2','Jinpeng 8B','RuixingDabao','guanfen 8','Jinshan 511'and'Provence'were used as experimental materials,the effects of low temperature treatment on seedling growth,survival rate,growth and yield of different tomato varieties were studied.the results showed that low temperature treatment significantly reduced seedling height by 12%-40%,and significantly increased seedling root fresh weight and survival rate after transplanting by 27%-120%and 51%-100%,respectively.The yield of tomato varieties'Rising Dabao','Guanfen 8','Jinshan 511'and'Provence'was significantly higher than that of varieties'NB007','Jinpeng 95-2'and'Jinpeng 8B'.The cracking rate of'NB007'and'Jinpeng 8B'was higher,which was 16%-22%.The rate of malformed fruit in'Golden shed 8B'and'Golden shed 95-2'was 0.8%-5.3%.Based on the seedling growth,survival rate,yield and other indicators,it is suggested that low temperature treatment should be carried out before greenhouse tomato planting in early spring,and varieties such as'RuixingDabao','guanfen 8','Jinshan 511','Provence'can be selected.
