摘要: 以旱优804、旱优649、旱优650和旱优813为试验材料,旱地和水田种植分别以旱优73和丰两优4号作对照,观察了节水耐旱稻(Oryza sativa L.)组合在水田和旱地种植的部分性状表现。结果表明,节水耐旱稻在旱地种植比对照旱优73增产4.86%~36.60%,在水田种植比对照丰两优4号增产-1.47%~3.51%;与水田种植相比,旱地种植各组合的垩白粒率大多明显降低,直链淀粉含量增加,且全生育期比水田种植要长10 d左右。

关键词: 节水耐旱稻(Oryza sativa L.), 组合, 产量, 外观品质, 生育期

Abstract: A field experiment with Hanyou 804,Hanyou 649,Hanyou 650 and Hanyou 813 as materials was conducted in 2019,the control was Hanyou 73 and Fengliangyou No.4 under water and dry cultivation conditions,respectively.Some characters of water-saving and drought-resistant rice (Oryza sativa L.) combinations under water and dry cultivation conditions were observed.The results showed that the yield of water-saving and drought-tolerant rice increased by 4.86% to 36.60% and -1.47% to 3.51% compared with control (Hanyou73 and Fengliangyou No.4) under dry cultivation and water condition,respectively.Compared with water cultivation condition,chalky grain rate of water-saving and drought-tolerant rice was decreased significantly under dry cultivation condition,but amylose content was increased.In addition,the whole growth period of water-saving and drought-tolerant rice under dry cultivation condition was about 10 days longer than that of water cultivation condition.

Key words: water-saving and drought-resistant rice (Oryza sativa L.), combination, yield, appearance quality, growth period
