| 采用小区试验研究了不同灌溉方式对津春4号黄瓜根系特性与产量的影响。结果表明,不同灌水方式之间黄瓜根系的特征值差异达到显著水平,前期交替沟灌结果期常规沟灌处理单株根条数、根长、根体积、根冠比均高于其余五种处理,根系伤流量为19.86 mg/min,根系活力高达0.55 mg/(g.h)。灌水方式对黄瓜单果重的影响不大,前期交替沟灌结果期常规沟灌处理的单株产量显著高于常规沟灌。因此,前期交替沟灌结果期常规沟灌有利于黄瓜根系的发育与产量的提高。 |

| 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. |
