| 摘 要： | 为了应对频发的极端干旱气候,2009—2010年引进生产上具有耐旱性强的水稻品种在非灌溉条件下试种,考察各品种在贵州种植的耐旱性,从中筛选出适宜贵州种植的耐旱水稻品种。结果表明:全生育期所需活动积温在2 558.8～3 639.3℃的耐旱性水稻品种适宜贵州各稻区种植;耐旱性较强及产量表现好的杂交稻品种有荃银1号、赣香优2833、黔两优58、黔优568、国稻1号等,常规稻品种武育粳3号、合系41号等;在干旱胁迫环境下,增加有效穗、穗总粒数及干物质重是栽培上应采取的主要措施。

| Abstract: | 118 introduced rice varieties with good drought resistance were cultivated under the non-irrigation condition from 2009 to 2010 in Guiyang to inspect their drought resistance and screen rice varieties with strong drought resistance for rice production in Guizhou.The results showed that the rice varieties with good drought resistance and 2 558.8～3 639.3℃ accumulation temperature during the total growth period could be cultivated in rice planting areas of Guizhou Province.The hybrid rice varieties with strong drought resistance and higher yield were Quanyin 1,Ganxiangyou 2833,Qianyou 568,Qianliangyou 58 and Guodao 1.The conventional rice varieties with strong drought resistance and higher yield were Wuyujing 3 and Hexi 41.The main cultivation measures to increase effective spikes,total grains per spike and dry matter weight should be adopted under the drought stress in rice cultivation. |
