A 100-mu area demonstration of new late indica rice variety Yufengzhan and its high yield cultivation technology

玉丰占是玉林市农科所利用香引一号作母本、八桂香作父本有性杂交育成的晚籼稻新品种,2007年3月通过广西农作物品种审定。2008年晚造在广西北流市民安镇才旺村进行玉丰占百亩连片高产栽培示范,项目采用适时早播,稀播培育多蘖壮秧;小苗规范移栽,强化低位分蘖;平衡施肥,适时追肥;合理用水及综合防治病虫害等配套栽培技术措施,玉丰占平均产量达9.03t/hm2,比对照七桂占增产23.4%,示范获得成功。
