摘　　要：针对海南省水稻主栽品种出现抗性减弱,丰产、稳产性减退的状况,于2010年引进广东省农科院水稻研究所选育的优质常规稻品种黄华占,在当年晚造及2011、2012年连续在海南省澄迈县永发镇进行早、晚造试种。结果表明:黄华占在海南种植表现株型集散度适中,后期熟色好,不易落粒,抗病虫性、抗倒性较强,生育期适中,具有高产稳产特性,可在海南进行大面积推广。黄华占是多穗型品种,宜采用小蔸稀植方式移栽;其早造对稻瘟病防治,以及晚造对白叶枯病、纹枯病、稻纵卷叶螟等病虫害防治措施不可或缺;其耐肥性较强,可适当提高施肥水平。Decline has been occurring in yield and disease resistance of leading varieties of rice in Hainan province in recent years, due to the constant planting. Against this background, Huanghuazhan, a high-quality and conventional rice variety recently bred in Rice Research Institute of Guangdong Academy of Agricultral Sciences, was introduced to Hainan province in 2010. Trial planting was carried out at Yongfa town of Chengmai county, during each cropping-season from 2010 to 2012 except the early-season of 2010. The results showed that Huanghuazhan was a moderately compact-type variety and had a medium duration of growth, good grain quality and a nonshattering phenotype. Moreover, this variety was characterized by high and stable yield, moderate resistance to diseases and insect pests, and high resistance to lodging. It can hence be popularized on a large scale in Hainan province. Huanghuazhan is a multi-spike variety, and its seedlings should be transplanted in low density. During the growth period, basic control measures are indispensible in early season for rice blast and in late season for bacterial blight, bacterial streak, and rice leaf roller. Huanghuazhan is also a variety with strong tolerance to fertilizer, suggesting that an increased level of fertilizer application is allowed when cultivating and managing this variety.
