灌溉方式对黄瓜结果期根系特征与产量的影响

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 sa...
