| Plot experiment was carried out to study the effects of different irrigation methods on cucumber root characters and yield during fruiting stage,Jinchun 4 was selected as indicating crops.The results indicated that root characters of cucumber were significantly different at 0.05 among different irrigation methods.Root number per plant,root length,root volume and root/top rate of early alternative furrow irrigation and late conventional furrow irrigation were much higher than other treatments.The bleeding sap of root,root activities and yield of each plant reached 19.86 μg/min,0.55 μg/(g·h) and 1.63 kg/plant respectively.Single mass of cucumber were not significantly different under different irrigation methods,while yield of each plant under early alternative furrow irrigation and late conventional furrow irrigation was significantly higher than that under conventional furrow irrigation.In conclusion,early alternative furrow irrigation and late conventional furrow irrigation could improve root growth and increase cucumber yield. |
