【摘要】 长江中游易涝区是洪涝灾害多发区 ,早熟早稻翻秋种植是一种有效的避灾减灾措施 ,为提高翻秋早稻产量和发展翻秋早稻生产提供科学依据及实用技术 ,对翻秋早稻高产栽培技术进行了研究。结果表明 ,赣早籼 37、赣早籼 4 5是 2个早熟、秧龄弹性较强的适种品种。这 2个品种播种期为 7月 2 0日 ,秧龄 15d ,移栽密度 16 .7cm× 13.3cm ,每穴 7～ 8本较为适宜 ,可以获得较高的产量。分析结果 ,翻秋早稻米质优于早稻米质更多还原

【Abstract】 There are many flooding disasters in the flood diversion area in the middle reaches of Changjiang River. It is a method of evading flooding disaster to plant early-maturing early rice in autumn. This paper deals with the technologies for high yield of early rice planted in autumn. The experimental results indicated that Ganzaoxian 37 and Ganzaoxian 45 are two early-maturing varieties with good seedling-age elasticity. The pattern of 20th July as the sowing date, 15 days as the seedling-age and 16.7cm×13.3cm with 7～8 seedlings per hole as the planting density is suitable for their culture. The quality of early rice planted in autumn is better than that in spring.更多还原
