Abstract: Hegang City is an important grain producing area. With the improvement of grain production level and the increase of yield year by year, the amount of straw resources is also increasing. However, the problem of grain straw waste is becoming increasingly prominent. Under the background of straw burning prohibition, there are still farmers who have been banned but have not stoppeds traw burning. The comprehensive utilization of straw has been aconcern for a long time. Straw returning to the field is the most commonly used method of comprehensive utilization of straw, which can improve the organic matter content of soil and supplement the nutrients in soil, provide sufficient fertility for crops growth, promote stable and high yield of grain; it can effectively solve the problems of rural straw waste accumulation and open burning, and adopt green and sustainable method to treat straw to improve the ecological environment; reduce the waste of resources and improve the utilization rate of straw. Therefore, in order to develop healthy and sustainable circular agriculture, alleviate energy shortage and reduce environmental pollution, by analyzing the current situation and policy subsidies of straw returning in Hegang City, it was pointed out that there were some troubles under the development, such as large technical difficulties, low mechanization level, and inadequate implementation of subsidy policies. Combine with the actual production, suit measures to local conditions, put forward suggestions such as strengthening technology promotion, accelerating the joint research of supporting equipment returning to the field, and strengthening financial subsidies and policy support, so as to provide theoretical reference for the development of straw returning in Hegang City, promote the comprehensive development of straw returning.
