Abstract：Heilongjiang Province is one principal grain production base in China, and under the background of water-saving and grain-increasing action, high efficiency water-saving irrigation schedules and requirements of corresponding equipment need to be solved urgently. As a result, the situation of completion of annual task, experience gained, existing problems and suggestions are analyzed since the project of water-saving and grain-increasing action has been implemented in the province. The results show that sprinkler irrigation technique is the major irrigation schedule for dry farmland in the province. It is predicted that the walking sprinkler and centered pivot irrigation sprinkler will become the major irrigation schedule gradually by 2020 from the walking sprinkler alone right now. It is estimated that 277 centered pivot irrigation sprinklers, 2 734 walking sprinklers and 415 micro sprinkler irrigation units will be needed in six years from 2015 to 2020 in the province.
