Effects of direct seeding and mechanized harvest on yield and economic benefit of ratoon rice Huanghuazhan
摘要
Abstract
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.关键词
