Effects of Irrigation Amount and Times on Yield Traits of Seed Melon in Yangqi Basin
[Objective]To research the effects of irrigation amount and times on yield traits of seed melon.[Method]We researched the effects of irrigation amount and times on yield of seed melon,fresh weight and seed rate in Yanqi Basin.The water requirement of each growth period was calculated.[Result]In 2012,2013 and 2014, yield of seed melon showed significant differences under different irrigating water quota treatments.Especially in 2012 and 2013, different treatments reached extremely significant level.In 2012,irrigation times had signifi-cant impacts on yield of seed melon.Irrigation times had significant impacts on fresh melon weight,and irrigation amount had extremely signifi-cant impacts, which further indicated that irrigation amount showed greater effects on fresh melon weight.Seed rate showed no significant differences under different irrigation amount and times.There was a quadratic parabolic relationship between the yield of seed melon and the water consumption, the optimal water requirement of the seed melon was 3 600 m3/hm2, and the best irrigation times were about 8 times. When the water supply was less than 3 600 m3/hm2,the yield of seed melon enhanced with the increase of water consumption.When the total amount of water supply was greater than 3 600 m3/hm2, the yield decreased.The water requirement of seedling stage accounted for 16.8% of the whole growth period, flowering fruit-bearing period, fruit enlargement period and mature period accounted for 26.9%, 38.2% and 18.1%.[Conclusion]This research provided theoretical basis for grasping the water requirement laws of seed melon, and for fully exterting the greatest potential of limited water resources.
