摘　　要：为了研究丘陵红黄壤区水稻一种两收高产关键技术,2013—2014年在湖北省咸宁市咸安区宝塔村用丰两优香1号,以头季栽插密度、促芽肥尿素施用量、留茬高度3个因子,组成12个处理进行品比试验。试验结果表明,在丘陵红黄壤区采用密度17 cm×20 cm、促芽肥225 kg/hm2、留茬高度与倒2叶叶枕平齐的一种两收栽培技术措施,2季产量达15 352.65 kg/hm2,可在生产中推广应用。In order to research the key technologies of harvest twice with cultivation once for rice in hilly yellow red soil region,the composition of the 12 treatment were compared taking Fengliang you No.1 as the material by first season planting densities,bud fertilizer amount of urea,stubble height in Baota Village of Xian′an District of Xianning City in Hubei Province from 2013 to 2014.Through testing and analysis,the results showed that through spreading the cultivation technical measures of harvest twice with cultivation once of rice using the density of 17 cm ×20 cm,bud fertilizer amount 225 kg/hm2,stay height with 2 leaves in hilly yellow red soil region,the yield could reached 15 352.65 kg/hm2,could be applied in production.
