< p > 1. Maize planting area will continue to decrease. Driven by planting income, maize planting area increased slightly in 2018/19, but the national intention to reduce maize planting area has not changed. In the 13th Five-Year Plan, the government put forward the goal of reducing maize planting area and increasing soybean planting area. According to the five-year plan, the area sown by Maize in China will be reduced by about 0.7% annually in the next four years, reaching 500 million mu (33.3 million hectares) by 2020. In 2018, the subsidy standard for maize producers in Heilongjiang Province was 25 yuan per mu of lawful planting area, while that for soybean producers was 320 yuan per mu of lawful planting area. In 2017, maize producers'subsidy was 122.46 yuan per mu and soybean planting subsidy was 173.46 yuan per mu. It can be seen that the policy orientation of the state is still to encourage soybean planting and reduce maize planting area. Maize planting area and yield are expected to decline in 2019/20.
