China News Service, July 15th, according to the National Bureau of Statistics website, the national summer grain production data released by the National Bureau of Statistics showed that the total national summer grain production in 2020 was 1.4281 million tons (285.6 billion catties), an increase of 1.208 million tons (24.2 million) from 2019 100 million catties), an increase of 0.9%. Among them, the wheat output was 1.3168 million tons (263.4 billion catties), an increase of 756,000 tons (1.51 billion catties) from 2019, an increase of 0.6%. Li Suoqiang, director of the Rural Department of the National Bureau of Statistics, explained that the planting area of ​​summer grains will be slightly reduced in 2020, but the yield has increased, and the country's summer grain production has again achieved a bumper harvest, and the output has reached a record high.

  Summer grain area decreased slightly

  In 2020, the national summer grain planting area was 26.172 million hectares (392.59 million mu), a decrease of 18.16 thousand hectares (2.724 million mu) from 2019, a decrease of 0.7%. Among them, the wheat planting area was 22,711 thousand hectares (340.66 million mu), a decrease of 2.735 million hectares (4.102 million mu) from 2019, a decrease of 1.2%.

  Li Suoqiang said that the main reason for the reduction of summer grain sown area: First, the structural reform on the agricultural supply side has been further deepened, and the optimization of the autumn and winter planting structure has been adjusted. Affected by factors such as market demand and planting efficiency, some major summer grain production areas actively expanded economic crops such as vegetables and rapeseed, and appropriately adjusted the wheat planting area. The second is the promotion and implementation of the seasonal fallow system in the groundwater over-exploitation area of ​​the North China Plain, and the relevant areas actively adjusted to reduce the wheat planting area. In order to further improve the quality of cultivated land and promote the implementation of the strategy of storing grain on land, in recent years, my country has combined seasonal fallow systems with comprehensive management of groundwater over-exploitation in some areas of the North China Plain, and has implemented a "one-season fallow, one-season planting" planting model. For example, 47 counties (cities) in Langfang, Baoding, Handan, and Xiong'an New Districts in the groundwater over-exploitation area of ​​Hebei Province organized the implementation of seasonal fallowing and restrictive harvesting measures, and the winter wheat planting area decreased more.

  Yield increase supports summer grain production

  The national output of summer grain per unit area was 5456.5 kg/ha (363.8 kg/mu), an increase of 83.4 kg/ha (5.6 kg/mu) compared with 2019, an increase of 1.6%. Among them, the yield per unit area of ​​wheat is 5798.0 kg/ha (386.5 kg/mu), an increase of 101.9 kg/ha (6.8 kg/mu) compared with 2019, an increase of 1.8%.

  Li Suoqiang pointed out that the main reason for the increase in the yield of summer grain: First, the climatic conditions are generally favorable, and the overall growth of wheat is good. During the winter wheat planting period, most of the main production areas have sufficient bottom moisture, and the wheat can basically sow the whole seedlings, and the emergence quality is high; during the winter, the wheat area temperature is high, the moisture content is suitable, to achieve strong seedlings, safe overwintering, sufficient tillering; During the booting stage, the light, temperature and water conditions in all regions are generally suitable, and the proportion of the first and second types of seedlings is generally higher than that of the same period of last year; the mature period of filling is mainly sunny and good weather, and the temperature difference between day and night is large, which is conducive to wheat dry matter accumulation and quality improvement, especially During the harvest, there were no high-temperature dry ripening and continuous rain, which ensured the smooth return of the summer grain. Judging from the number of grains examined on site, the number of ears per mu of winter wheat this year is generally higher than that of the previous year, and the number of grains per ear is basically the same as that of the previous year. The second is to strengthen field management, effective control of diseases and insect pests in the later period. In response to the characteristics that the warm winter climate will cause wheat rust and gibberellosis in the later period of wheat, local governments will formulate prevention and control plans as early as possible, carry out monitoring and early warning, increase investment in funds, and strengthen the specialized services of “one spray and three prevention” in the later stage of wheat to effectively prevent and control Diseases and insect pests have not caused great damage to wheat yield and quality. Although the new coronary pneumonia epidemic has a certain impact on the field management and the supply of agricultural materials during the wheat rejuvenation period, in the later period, the agricultural material transfer and wheat field management have been strengthened in various regions. Overall, the epidemic situation has not had a major impact on wheat production.

  Li Suoqiang said that the summer grain production will achieve another bumper harvest in 2020, which lays the foundation for stabilizing grain production throughout the year, strengthens confidence for continuing to do a good job of "six stability", fully implement the tasks of "six guarantees", and for building a well-off society in an all-round way. The fight against poverty has further strengthened the foundation.
