In this paper, Irrigation Rice in Sanjiang Plain water is low, resulting in the field of temperature and soil temperature is too low, affecting the normal development of rice, causing severe cuts rice situation, through field trials, focus on the sun sinks, channels and other technical and engineering warming water-saving irrigation, irrigation water temperature on the field, soil temperature regulation and water-saving irrigation irrigation Rice Yield and eventually proposed to solve irrigation rice chilling an effective manner. Test results obtained are as follows: (a) drying pools, water channels warming sun and its influencing factors in Sanjiang Plain rice warming technology development wells should be based on the original with pool, drainage warming based, other growth Temperature measures supplement. Drying pool warming is mainly affected by temperature, drying pool area, pool depth of the sun. Channel is mainly affected by warming temperatures, channel length, channel width to depth ratio, flow and other factors. (2) high-yielding rice soil water saving energy saving control standards based on high-yielding rice soil moisture regulation principles and three or four years experience in controlling irrigation field trials, this test uses soil moisture turning green energy regulatory standards should be kept fully saturated soil moisture, soil water tension minimum, that the soil water potential is zero; early tillering, medium mainly light control, the control-based, so that the soil diurnal temperature increase, good light, soil heat flux and high redox potential ; tillering stage should be re-oriented control to control nitrogen uptake, increased leaf carbon to nitrogen ratio, prompting rice from vegetative growth to reproductive growth timely conversion; booting and heading to the main light control, alternating wet and dry; milky interim control , ripening period Shaitian. (3) water-saving irrigation, irrigation on the field within the water temperature and soil temperature regulation controlled irrigation conditions, using the field surface drying water warming, drying water for 1 hour, the water temperature average increase of 7 ~ 8 ℃, after 2 hours drying water, fields within Average water temperature reaches above 20 ℃, meet crop irrigation water for the minimum requirements. Control of irrigation water layer growth period is not established, low soil moisture, soil heating up fast, is conducive to enhancing soil temperature, soil layers the average ground temperature 1 ℃ higher than about intermittent irrigation on rice yield increase has a significant impact. (4) increase of water-saving irrigation, water saving potential in irrigation conditions, the 2006 rice production and surface water irrigation irrigated rice production was flat. 2007 As good moisture control, irrigation rice yield than surface water irrigated rice yield 6%. Visible through the development of water-saving irrigation, irrigation of rice to overcome cold damage, and surface water irrigation to obtain the same yield, high yield based on the re-production. Irrigation control than intermittent irrigation yield of 7% to 8%, water 10.4%, higher than the provincial average of 25.3% water, irrigation water productivity is 1.2 times intermittent irrigation. In summary, Rice in Sanjiang Plain vigorously develop water-saving technologies warming should be based on the original with pool, drainage warming-based, supplemented by other measures warming, while focusing on irrigation management and water-saving irrigation methods integrated apply. The drying of water, water, irrigation, water-saving unite timely and appropriate scientific irrigation, improved field heat and humidity of the environment environment, adjust crop growth conditions and processes in order to achieve water conservation, warming, increase the purpose of the Sanjiang well irrigated rice to solve the problem of cold damage provides an effective way.
