以5个杂交稻为材料，探索直播—再生稻栽培技术。安排再生稻头季播种期时，应当根据品种的生育期特性，把再生稻再生季的抽穗扬花期安排在9月中旬为宜。水稻品种的分蘖能力不同，会影响到再生季的有效穗数，直播-再生稻栽培要选用分蘖力较强的品种为宜。再生穗着生节位高度与品种特性有关。直播稻栽培的关键技术是：保匀苗、除杂草、防倒伏和治病虫。

The cultural techniques of direct sowing-ratoon rice were studied with five rice hybrids as experimental material. The arrangement of main rice sowing date should be based on growth-development characteristics of varieties, and the suitable flowering stage of ratoon rice was arranged before mid-September. The tillering capacity of rice varieties was different, which affected panicle number of ratoon rice. Therefore, the appropriate varieties of direct sowing-ratoon rice should have strong tillering ability. The height of rationing panicles locating node was related to variety characteristics. The key cultivation techniques for direct sowing rice lied in ensuring uniform seedlings, controlling weeds, preventing lodge and controlling diseases ＆ pests.
