冀西北坝上地区甜瓜品比试验

Preliminary Report on the Comparison of Melon Varieties in Bashang Region of Northwestern Hebei

[目的]对引进的5个甜瓜品种进行比较试验,以筛选出适合冀西北坝上地区露地栽培的甜瓜品种。[方法]对引进的甜瓜品种进行植物学性状、经济性状、产量、综合抗性及水分利用效率等方面的比较。[结果]4个品种表现均好于对照,其中"红城5号"从开花到果实成熟需时为35 d,中心含糖量达15.7%,对霜霉病、炭疽病和白粉病3种病综合抗性最强,坐果率达96.7%,果实黄白色,肉质甜脆,水分利用效率为471.00 kg/(hm2.mm),产量为17 150.85 kg/hm2,均优于其他品种。[结论]"红城5号"综合性状最优,适合在冀西北坝上地区推广,"真甜王"的综合性状略低于"红城5号",也是一个可以推广的品种。

[Objective] The melon variety suitable for planting in open field in the Bashang region of northwestern Hebei was screened out through the comparison test of five introduced melon varieties. [ Method] The botany character, economic trait,yield, comprehensive resistance and water-nsing efficiency of melon varieties introduced were compared. [ Results ] The perfonnance of four varieties were better than that of the CK, anaong which, the variety- Hougvbeng No.5 was the best one in follow traits：the time from flowering to fruit maturity：35 days; the content of sngar, 15.7% ; its resistance to downy mildew, anthracnese and powdery mildew; the rate of fruit-setting, 96.7 % with yellow-white fruit, fleshy and crisp meat, the water-using efficiency,471.00 kg/hm2＂ mm and the yield, 17 150.85 kg/hm^2. [Conclusion] The variety-Hongcheng No.5 was the best one and suitable for the extension in the open field in the ＂Bashang region of northweste traits in Hebei and also the performance of the variety---Zhengtianwang was slightly lower than Hongcheng No.5, was suitable for planting in the region.
