广两优7203是中国水稻研究所和中国科学院遗传与发育生物学研究所用广占63S与中恢7203组配而成的强优势两系杂交稻组合,2013年通过浙江省审定,2014年通过国家审定。本文主要介绍了该组合在江西大面积试验示范的表现及高产栽培技术。 Guangliangyou 7203 is a two-line hybrid rice combination with two dominant lines consisting of Guangzhan 63S and Zhonghui 7203, which was established by China Institute of Genetics and Developmental Biology, Chinese Academy of Rice Research and Chinese Academy of Sciences. In 2013, it was approved by Zhejiang Province and passed the national Validation. This article mainly introduces the performance of this combination in large-scale experimental demonstration in Jiangxi and its high-yielding cultivation techniques.

在西南稻区的四川省、云南省、贵州省和重庆市实施了水稻农民习惯施肥技术与空白试验(不施肥)对比试验。结果表明,农民习惯施肥技术具有如下不足:一是水稻投入产出率低;二是肥料利用率低;三是大面积水稻产量不高,单产仅520.9 kg/667 m~2;四是水稻生产穗数不足。针对上述问题,笔者从提高水稻产量角度出发,提出了相应的施肥对策。
