Based on the food security idea of “storing grain on the ground” and the storage pressure of three major grain crops，the sown area of cereals in China was moderately reduced in 2018，while the sown area of soybean，cotton and sugar crops increased.From the perspective of food security，although the sown area of grain has decreased，the per unit yield has increased，so the annual grain output has slightly decreased compared to the previous year，and it remains at a high level.In 2018，except for corn，the imports of wheat，rice，barley，sorghum，cassava and soybean crops decreased，and rice exports hit a new high.Among the cash crops，the imports of cotton，edible vegetable oil and sugar increased during the same period.In 2018，except for the corn price，the price of wheat，rice，soybean，oil and sugar crops have decreased.The main reason for the increasing cost of production is attributable to the increase in land cost and human cost.In 2019，the output of rice and wheat is not likely to decrease in a substantial manner，the high quality and high price system will be established.The corn production will possibly increase slightly in some places，but the probability of a large increase can be hardly achieved.The production areas of soybean and oil crops will possibly expand with a high probability of production increase.The sugar production will possibly increase.In 2019，the increase in rice prices seems hardly to happen，while the probability of a decrease in wheat and soybean prices is high.Corn and cotton prices are more likely to rise，and sugar prices will be able to bottom out.Affected by a widening price gap at home and abroad and the increase in domestic production cost，the import pressure of the crops industry is still relatively high.
