在已有研究的基础上,选用8个番茄品种进行越冬栽培试验,采用隶属函数方法,对番茄植株抗寒性生理指标进行综合评价。结果表明:“光辉101”、“劳斯特”品种叶片和根部各指标的隶属函数值较大,抗寒性较强,较适合黑龙江中部地区进行日光温室越冬栽培,表现较差的是“极早红粉”。 Based on the existing research, eight tomato varieties were selected for overwintering cultivation experiment, and the membership function method was used to evaluate the physiological indices of cold tolerance of tomato plants. The results showed that the membership functions of the leaves and roots of “brilliant101” and “louse” were larger and their cold resistance was stronger, which was more suitable for the overwintering cultivation in solar greenhouse in the central part of Heilongjiang Province, with poor performance It is “very early pink ”.
