黄瓜夏秋栽培品比试验

为筛选适宜夏秋露地栽培的黄瓜品种。采用宽窄行栽培,以津研4号为对照,观察了津优1号、津优4号等6个黄瓜品种在高海拔地区夏秋期间栽培的表现。7个品种的产量排序为津优4号>中农8号>津优1号>津春4号>津育4号>新秀>津研4号。津优4号、中农8号的产量为61 683.06、0 117.0 kg/hm2,分别比对照增产11.53%、11.24%。单瓜质量以中农8号最重,其次为津优4号。津优4号雌花节位出现较早,以主蔓结瓜为主,中农8号主蔓最长,节数较多。津优4号、中农8号对霜霉病抗性较强,病情指数分别为12.3和16.4。津优4号和中农8号的商品性和抗病性均较好,适合高海拔山区夏秋栽培,可大面积推广使用。

Variety Comparative Test of Planting Cucumber in Summer and Autumn

The study aimed to screen out the cucumber variety suitable for open cultivation in summer and autumn.With Jinyan 4 as CK,the cultivation behaving of 6 cucumber varieties such as Jinyou 1 and Jinyou 4 in the area with high altitude during summer and autumn was observed in the cultivation with wide and narrow rows.The yield order of 7 varieties was: Jinyou 4>Zhongnong 8>Jinyou 1>Jinchun 4>Jinyu 4>Xinxiu>Jinyan 4.The yields of Jinyou 4 and Zhongnong 8 were 61 683.0 and 60 117.0 kg/hm2,increasing 11.53% and 11.24% than CK resp.The single fruit weight of Zhongnong 8 was most,and the next was Jinyou 4.The nodes of female flower of Jinyou 4 grew out earlier,and the fruits were most on the main vine and the main stem of Zhongnong 8 was longest with the most nodes.Jinyou 4 and Zhongnong 8 had stronger resistance to downy mildew,with disease indices of 12.3 and 16.4 resp.Both Jinyou 4 and Zhongnong 8 have better commerciality and disease resistance,which are suitable to plant in the mountainous area with high altitude and can be popularized and used in large area.
