| 摘 要： | 重庆是再生稻的主产区之一,积极发展再生稻生产对确保粮食安全,改善稻米结构、增加农民收入、满足城乡人民生活需求等都具有重要意义.手工栽秧、机栽秧、抛秧、直播是目前水稻的主要栽培方式.本研究设置了人栽人收、人栽机收、机栽人收、机栽机收、抛秧人收、直播人收6个处理,比较了不同栽培处理下杂交水稻的再生性、再生稻产量及中稻-再生稻产量.结果表明:人栽人收在再生性、再生稻产量、中稻-再生稻总产上都具有明显的优势,依次为人栽机收、机栽人收、机栽机收、抛秧人收,直播人收处理下表现最低.

| Abstract: | Chongqing is one of the major grain yield areas of ratooning rice.Development of ratooning rice actively could help to ensure food security,improve rice structure,increase income of farmers and meet the needs of urban and rural people’s living.artificial transplanting,machine transplanting,throwing transplanting,direct seeding were mainly planting patterns.The trials of artificial transplanting manual harvest,artificial transplanting machine harvest,machine transplanting manual harvest,machine transplanting machine harvest,throwing transplanting manual harvest,direct seeding manual harvest were carried out to compare the regeneration, ratooning rice yield and rice-regeneration yield under six different planting patterns of hybrid rice. The results showed that artificial transplanting manual harvest,had obvious advantages in regeneration,ratooning yield,rice-regeneration on the total production,followed by Artificial transplanting machine harvest,machine transplanting manual harvest,machine transplanting machine harvest,throwing transplanting manual harvest,direct seeding manual harvest were the lowest of all. |
