井灌水稻增温新机理与新技术研究初探

Study of New Technique and Mechanism about Increasing Temperature of Well Irrigation for Rice

井水温度低,成为影响黑龙江省井灌稻生产的主要矛盾,为此,井水增温意义重大。历来井水增温多采取用晒水池和延长渠道增温等方法,已为井灌稻生产作出重大贡献。随着生产实践的深入,近年来又出现井灌稻增温新机理和新技术,通过生产实践调查和试验,同样取得增温效果,值得深入研究。

Low well water is principal contradiction of well irrigation rice production in Heilongjiang Province. Always well water warming much adopts with exposes to the sun methods and so on basin and extension channel warming, has make the important contributions to the rice production. Along with production practice＇s thorough, presented the new mechanism and the new technology for well irrigation warms in recent years , which make the warming progress. Through production practice investigation and experiment, they are worth the deep research.
