| Abstract: | Based on experiment on the 852 farm in the Heilongjiang Province,which applying wet irrigation technology during the whole rice growing period,using the big area contrast method,then conducting the analysis of the ground temperature,observing the temperature change at different depth and in different growing period.The paper is shown that after applying water-saving irrigation technology,the ground temperature will be 0.6 centigrade above applying the regular irrigation technology,the ground temperature changes will directly affect the rice growing,bring the raising of rice tiller capability by 10.9%,these will save the water resource,cut the production cost,raise the rice production capability and the benefits. |
