直播机收再生种植对黄华占产量和经济效益的影响OA
Effects of direct seeding and mechanized harvest on yield and economic benefit of ratoon rice Huanghuazhan
再生稻是轻简化生产方式的重要组成,拥有省工、省种、省肥、省药及生态环保等优势,对于保障我国粮食安全具有重大意义.本文于2024年对湖南省再生稻核心生产区—大通湖区千山红镇开展黄华占直播机收再生种植产量和经济效益的调查.结果表明,在正常年份下,千山红镇再生稻头季产量为350～680 kg/667m2,再生季产量为140～330 kg/667m2,周年产量为650～1 010 kg/667 m2,经济效益在191～1 361元/667 m2.合理安排再生稻播期、头季收获期、再生季抽穗杨花期是降低不利气候危害的重要途径.千山红镇直播机收再生稻种植建议4月10日—4月20日播种,8月15日前收获头季,确保9月15日前再生季齐穗.
Ratoon rice,one of light and simplified production modes,has the advantages of saving labor,planting,fertil-izer,medicine and ecological environment protection,which is of great significance for ensuring food security in China.In this study,the yield and economic benefit of huanghuazhan direct seeding system were investigated in Qianshanhong town of Datong-Lake district,the core area of ratoon rice in Hunan province for2024.The results showed that under normal years,the yield of ratoon rice in Qianshanhong town was 350～680 kg/667m2 in the first season,140～330 kg/667m2 in the second season,and the annual yield was650～1 010 kg/667m2,and the economic benefit was as high as 191～1 361yuan/667m2.Reasonable arrangement of sowing date,harvesting date of first season and heading and flowering date of ratoon rice is an important way to reduce adverse climate damage.Direct seeding system with ma-chine-harvest of ratoon rice in Qianshanhong town is planted on April 10—April 20 sowing,before August 15 harvest the first season,to ensure the heading date of the ratoon season before September 15.
