摘要
近年来广东省大面积推广应用大量的优质稻品种及其配套技术,丝苗米在全省种植面积大幅增加。19香是广东省主导推广的丝苗米品种。2020年兴宁市丝苗型香稻19香丝苗香米周年产量1300.12 kg/666.7m^(2),刷新了双季稻香米年平均亩产量全国纪录。该品种在示范种植中田间表现良好,株型中集,分蘖力强,穗长粒多,抗倒力强。文章基于兴宁市的示范种植,总结了19香创高产的栽培关键技术要点,提出高产栽培技术管理措施,以期为丝苗型香稻品种的高产栽培提供参考,为我国的粮食安全作出贡献。
In recent years,a vast number of high-quality rice varieties and their supporting technologies have been widely promoted in Guangdong Province,resulting in a significant increase in the planting area of silk seedling rice,of which 19 Xiang is representative.In 2020,the annual yield of 19 Xiang in Xingning City was 1300.12 kg/667 m2(1 mu),breaking the national record for the average annual yield of double season fragrant rice per mu.In addition,this variety has good field performance during demonstration planting,with a medium-set plant shape,strong tillering ability,long spikes and multiple grains,and strong lodging resistance.Based on this,the article summarizes the key cultivation techniques and management measures of 19 Xiang,with a view to providing reference for the high-yield cultivation of silk seedling fragrant rice varieties and contributing to China’s food security.
