水稻两优0328旱直播栽培技术初探

Preliminary Study on Cultivation Techniques of Direct Seeding Rice Liangyou 0328

安全、稳定的水稻(Oryza sativa L.)生产是保障中国粮食安全的重要内容。鄂西北地区是传统的麦稻轮作区。选用双季晚籼新品种两优0328作麦后稻直播种植,探索以水资源低耗、氮肥高效、省工省时为主要内容的麦后稻旱直播轻简栽培技术,并对麦后稻旱直播的推广价值和品种选择进行了讨论。

Safe and stable rice production plays an important role in food security of China. The northwest of Hubei province is a traditional wheat and rice rotation area. A new double season late Indica rice variety, Liangyou 0328, was chosen for direct-seeding cultivation after wheat harvest in this study, to explore a new simple cultivation technological system of rice direct-seeding after wheat harvest under drought situation. This system was aimed at less water consuming, efficient nitrogen using, and labour and time saving. The value of application and variety selection of rice direct-seeding after wheat harvest under drought situation were discussed.
