19 171month to 1922, the newly born socialist Soviet Union waged a revolutionary civil war to resist foreign armed interference and destroy domestic reactionary troops. Grain shortage is increasing. 19 19. 1, the Soviet regime, issued a decree on the surplus grain collection system, stipulating that the amount of grain needed by the country is the "surplus grain" that must be collected. Farmers must sell all surplus grain according to the amount stipulated by the state and give it to the state at the stipulated price. The state practices a monopoly policy on grain and does not allow private trading. According to the policy, farmers must sell grain to the state at the prescribed price, and they can buy industrial products at a fixed price. With the civil war, the state could not supply industrial products, and the ruble depreciated rapidly, so farmers actually paid grain to the state free of charge. The implementation of severe punishment has damaged the interests of farmers, achieved obvious results in a short period of time, alleviated urban famine, and ensured the food supply of the Red Army at the front line, which has become an important factor in reversing the war situation.
