水稻节水增效栽培技术在江西的应用

根据江西的实际,将旱育秧(含抛秧)、节水整地与栽秧、浅湿干交替灌溉3项主体节水技术,与节水稻田化学除草、平衡施肥与合理经济施肥、化学调控培育多蘖壮秧等配套技术相结合,优化组装形成抛秧、旱床育秧、化控湿润矮壮秧3项节水栽培技术体系,进行了对比试验和大面积示范推广。结果表明,实施这3项节水栽培技术体系可以提高水稻产量、节约用水、节省成本、提高效益与资源利用效率。讨论了节水增效栽培技术在南方稻区的应用前景。

Application of Water-saving and Benefit-increasing Rice Cultural Techniques in Jiangxi Province

According to the practice of Jiangxi province, through combining three water-saving techniques (raising seedlings on dry bed or seedling-thrown tray, preparing paddy and transplanting by water-saving mode, and alternative irrigating in the pattern of shallow water, wet and dry) with several coordinative cultural techniques such as chemical weeding, balanced, reasonable and economic fertilization, and raising vigorous seedlings with more tillers by chemical regulation, three superior water-saving cultural technique systems (seedling-thrown technique, raising seedlings on dry bed, and raising short and strong seedlings on wet bed by chemical regulation) were composed. The results of contrast tests and demonstration as well as popularization showed that the three water-saving cultural technique systems could increase rice yield, save water and costs, enhance benefit and efficiency of resources utilization. Finally, the prospects of applying the water-saving and benefit-increasing techniques in southern rice area were discussed.
