In 2022, the total output of summer grain in China was 147.39 million tons (294.8 billion jin), an increase of 1.434 million tons (2.87 billion jin) over the previous year, an increase of 1.0%. Among them, the wheat output was 135.76 million tons (271.5 billion jin), an increase of 1.286 million tons (2.57 billion jin), an increase of 1.0%.
I. The sown area of summer grain increased slightly
In 2022, the sown area of summer grain nationwide was 2653000 hectares (397.95 million mu), an increase of 921000 hectares (1.382 million mu) over the previous year, an increase of 0.3%, achieving growth for two consecutive years. Among them, the sown area of wheat was 22962000 hectares (344.43 million mu), an increase of 508000 hectares (762000 mu), an increase of 0.2%.
The main reasons for the steady and slight increase in the sown area of summer grain are as follows:first, compaction of grain production responsibility. The Party Central Committee and the State Council attach great importance to the supply of grain and important agricultural products, strictly implement the assessment of the food security responsibility system, compact the production responsibility at all levels, implement the same responsibility of the party and the government for the protection of cultivated land, strictly observe the red line of cultivated land, and strengthen the control of the use of cultivated land. Second, increase policy support. The state raised the minimum purchase price of wheat, stabilized farmers’ grain subsidies, increased incentives for major grain producing counties, promoted the full cost insurance and planting income insurance of the three major grain crops, and fully covered major grain producing counties in major provinces. All localities also made overall arrangements for funds to increase support to ensure farmers’ grain production income. At the same time, the prices of wheat and other grains have increased, and farmers’ enthusiasm for growing grain has increased. Third, stabilize the sown area of winter wheat. Hebei, Shanxi, Shandong, Henan, Shaanxi and other places overcame the impact of the severe autumn flood and basically stabilized the sown area of Winter Wheat by adjusting the planting structure and expanding the area of non disaster areas. The sown area of Winter Wheat in China was 2232000 hectares (334.81 million mu), a slight decrease of 673000 hectares (1.01 million mu) over the previous year, a decrease of 0.3%. Fourth, expand the planting scale of spring wheat. Xinjiang, Gansu, Ningxia and other places have actively expanded the planting of spring wheat. The sown area of spring wheat in China is 642000 hectares (9.62 million mu), an increase of 118.1 thousand hectares (1.771 million mu) over the previous year, an increase of 22.6%, effectively making up for the reduction in the area of winter wheat due to disasters.
II. The unit yield of summer grain increased slightly
In 2022, the national summer grain yield was 5555.6 kg/ha (370.4 kg/mu), an increase of 34.9 kg/ha (2.3 kg/mu) over the previous year, an increase of 0.6%, of which the wheat yield was 5912.3 kg/ha (394.2 kg/mu), an increase of 43.0 kg/ha (2.9 kg/mu), an increase of 0.7%.
The main reasons for the slight increase in summer grain yield in China are as follows:first, the overall favorable meteorological conditions. Although the northern winter wheat area experienced autumn flood last year, the temperature rose rapidly after the beginning of spring, and the disasters such as”cold in late spring” and spring drought occurred less, which was conducive to wheat jointing and tillering. Since the beginning of summer, the soil moisture is sufficient, and the temperature difference between morning and evening is large, which is conducive to grain filling. Most of the southern production areas are suitable for sowing, and the meteorological conditions in the growth stage are good, especially since spring, there is sufficient light and temperature, which is conducive to growth and yield formation. Second, a number of measures have been taken to make precise efforts. In view of the delay of sowing date, all localities should improve the quality of soil preparation, increase the amount of sowing, and increase the application of base fertilizer to reduce the impact of late sowing; Aiming at the high proportion of weak seedlings, we should carry out the action of”strengthening seedlings through science and technology” to effectively promote the transformation of seedlings; In view of the high risk of diseases and pests, we carried out unified control and”one spray, Three Preventions” to fully cover the area of wheat stripe rust and scab; In view of the impact of the epidemic in some areas, we should timely get through the blocking points of farmers’ going to the fields, agricultural materials to the stores, and agricultural machinery on the road, so as to promote the orderly implementation of spring management and summer harvest. Third, production conditions continued to improve. In recent years, all localities have accelerated the construction of high-standard farmland, strengthened the transformation of medium and low yield farmland, made efforts to improve farmland infrastructure conditions, cultivated and popularized excellent varieties, built a diversified agricultural socialized service system, and promoted the steady improvement of grain yield per unit area.
