寒地水稻滴灌旱作节水栽培技术研究

Research on Water-saving Cultivation Technique of Dry Farming by Drip-irrigation Model on Rice in Cold Region

以18个水稻品种为试材覆膜滴灌处理,试验结果表明:垦稻9、空育131、垦鉴稻6号、垦稻19等品种较适合旱种水稻的生产,垦稻9和垦稻19为主茎10片叶品种,生育期短,较适合水稻旱种,但因抗倒伏能力一般,栽培措施上要加强管理,垦鉴稻6号为主茎12片叶品种,在2013年的气候条件下能够成熟,但在其他年份能否正常成熟有待进一步验证。整个生育期灌溉用水量约为290 m^3。

The test of water-saving cultivation technique of dry fanning by drip-irrigation model were made by 18 rice varieties and the results indicated that Kendao-9, Kongyu-131, Kenjiandao-6 and Kendao-19 which were suited for dry farming, Kendao-9 and Kendao-19 had 10 leaves on main stem with shorter growth period, and were suited for dry farming, they should be strengthen field management because of their lodging-resistant capability, Kenjiandao-6 had 12 leaves on main stem, it can mature under the climate condition of 2013, but it need further testing and research on the maturity can be normal in other years. The irrigation water demand account were about 290 m3 in the whole growth period.
