利用隶属函数法综合评价4个华北型黄瓜品种

Comprehensively Evaluate 4 North China Type Cucumber Varieties Using Membership Function Method

为了科学地筛选出适宜鲁南地区的早春黄瓜优良品种,提高早春黄瓜种植茬口产量,获得更高的经济效益,将4个华北型黄瓜杂交新品种(津早218、圣优93、圣夏108、冬灵48)进行春提早栽培,对其植物学特性、果实外观品质、商品性、品质、产量和抗病性等进行比较,并利用模糊隶属函数法对瓜条性状、产量,品质、抗病性进行综合评价。结果表明:圣优93采收天数较其他品种延长5~7 d;与其他试验品种相比,圣优93霜霉病病情指数最低,为15.38,并且产量显著高于其他参试品种,为213035.70 kg·hm^(-2);圣优93可溶性固形物含量方面与津早218没有显著差异,但均显著高于其他参试品种,其总糖量方面显著高于其他品种,极显著高于冬灵48;经模糊隶属函数法综合排名,圣优93总隶属函数值排名第1。综上所述,圣优93可作为该地区黄瓜品种栽培的首要选择,隶属函数法能够较客观地评价各品种表现,可辅助黄瓜新品种的综合评价。

In order to scientifically screen out the best varieties of early spring cucumber suitable for the southern area of Shandong Province,increase the crop yield of early spring cucumber and obtain higher economic benefits,four new hybrid cucumbers of North China type(Jinzao 218,Shengyou 93,Shengxia 108,Dongling 48)were cultivated in early spring.Their botanical characteristics,including fruit appearance quality,commercial property,quality,yield and disease resistance were compared,and used the fuzzy membership function method to comprehensively evaluate the characteristics,yield,quality,and disease resistance of melon strips.Quality and disease resistance were evaluated comprehensively.The results showed that the harvesting days of Shengyou 93 were 5-7 days longer than those of other varieties.Compared with other varieties,Shengyou 93 had the lowest downy mildew disease index(15.38),and its yield was significantly higher than other varieties(213035.70 kg·hm^(-2)).There was no significant difference in soluble solid content between Shengyou 93 and Jinzao 218,but it was significantly higher than other varieties,and its total sugar content was significantly higher than other varieties,and it was significantly higher than Dongling 48.According to the comprehensive ranking by fuzzy membership function method,the total membership function value of Shengyou 93 ranked the first.In conclusion,Shengyou 93 can be used as the primary choice for cucumber cultivar cultivation in this area,and membership function method can objectively evaluate the performance of various varieties,which can assist the comprehensive evaluation of new cucumber varieties.
