摘要
长期连作水田土壤粘朽、冷凉 ,不利水稻高产 ,更不利水田改旱田 ,三江平原有“水改旱瞎一半”之戒律。只有加强排水 ,采取秋耕、深松 ,加上促早熟等措施 ,才能创高产。由于生态环境改变 ,可减少施用化肥和农药 ,实现低耗优质 ,减少污染。其实“水旱轮作”是我国优良传统农业技术 。
Much attention is paid to strengthen the drainage system, adopt autumn cultivating, loosen the soil deeply, introduce the improving early maturing technology, as well gain the high yield. In addition, with the change of ecological environment, the use quantity of the fertilizer and pesticide will be reduced. The lowering expenditure, good quality and reducing pollution also will be realized. The rotation cultivating between the paddy and the dry land is good traditional agricultural technology in China, which will be also mainly developing direction to high quality, high yield and high benefit sustainable agriculture development in future.
