In order to grasp the situation, problems and solutions of information construction of grain storage in Liaoning province, a systematic investigation was carried out on 13 representative national warehouses in the province. The results show that the main contents of information construction in national warehouses include digital electronic temperature measurement system, grain surface video monitoring system , grain situation remote monitoring technology , early warning system for grain situation monitoring and analysis , grain quantity monitoring system , automatic ventilation control system, intelligent access and storage management system, wireless transmission technology of storage data, etc. The main problems include a large number of "isolated islands" in grain storage data, the lack of information construction funds in grass-roots units, the outdating of grain storage facilities, the aging of employee and the lack of compound talents. It is suggested that the information construction of national storage should be carried out step by step through overall planning, adopt the mode of joint investment, equip or improve the supporting facilities and equipment for grain storage, and build the information technology personnel team, etc.
