Of which, the sown area of grain was 22,711 thousand hectares (340.66 million mu), which decreased 273.5 thousand hectares (4.102 million mu) over last year, and a decrease of 1.2 percent.

II. The yield per unit area of summer grain was 5,456.5 kg/ha (363.8 kg/mu), increased 83.4 kg/ha (5.6 kg/mu) over last year, with a growth rate of 1.6 percent. Of which, the yield per unit area of grain was 5,798 kg/ha (386.5 kg/mu), increased 101.9 kg/ha (6.8 kg/mu) over last year, with a growth rate of 1.8 percent.

III. The total output of summer grain was 142.81 million tons (285.6 billion jin), increased 1.208 million tons (2.42 billion jin) over last year, with a growth rate of 0.9 percent. Of which, the total output of grain was 131.68 million tons (263.4 billion jin), increased 756 thousand tons (1.51 billion jin) over last year, with a growth rate of 0.6 percent.

Explanation on the Summer Grain Output Survey

The data released by the National Bureau of Statistics (NBS) on the summer grain output, were estimated from the sample survey in the main-producing summer grain regions taking the province as the total population, and major investigation in the non-main-producing regions.

I. Statistical Approach

Summer grain includes grain, beans and tubers harvested in summer. Of which, grain harvested in summer includes wheat, barley, oats and buckwheat; beans harvested in summer include broad beans and peas, tubers harvested in summer include potatoes and sweet potatoes.

II. Survey Coverage

Among 17 provinces (autonomous regions and municipalities), including Beijing, Tianjin, Hebei, Shanxi, Jiangsu, Anhui, Shandong, Henan, Hubei, Chongqing, Sichuan, Guizhou, Yunnan, Shaanxi, Gansu, Ningxia, Xinjiang, more than 400 counties (cities) are sampled as national sample counties (cities), and the survey organizations of NBS at provincial level are in charge of organizing the survey organizations in sampled counties to conduct sample survey and actual cutting, and finally get the summer grain estimates.

The output of summer grain in 8 provinces (autonomous regions and municipalities), which including Shanghai, Zhejiang, Fujian, Jiangxi, Hunan, Guangdong, Guangxi, and Hainan, are obtained by estimation from the major investigation by related survey organizations at provincial level.

III. Survey Sample

The sample survey on summer grain output consists of sown area sample survey and yield per unit area sample survey.

The sample survey on summer grain sown areas was conducted in national survey counties (cities). There were more than 6000 sample villages in China, and three sample plots with an area of about 60 mu were selected from each sample village. In the survey season, all the natural plots within the sample plot and its cover were investigated, and the survey organizations at province level estimates the summer grain sown areas at province level based on the basic survey data.

The sample survey on yield per unit area was conducted in the area of survey plots selected by the national survey counties (cities). Nearly 4,000 yield measurement sample points and more than 10,000 yield test plots were selected in the whole country. 3-5 small plots with 10 square feet were selected from each plot according to the requirements. The average wheat yield level in the whole province was calculated by actual cutting of wheat in the sample plots.

IV. Output Measurement Method

The on-site measurement on wheat output refers to the investigators in the grass roots, before harvesting, in accordance with 'Statistical Reporting System on Agricultural, Forestry, Animal Husbandry and Fishery', stepping in the field and estimating the output of planting land plots one by one, and ranking them by output, then selecting a certain segment and marking them out. During harvesting period, investigators of the survey organizations at county level or assistant investigators will put sample and select sample on-site, and then estimate the yield per unit area through threshing, drying, water-checking, weighting and other steps on the selected land segments. The survey organizations at province level estimate the provincial average yield per unit area based on the data from the selected land segments.

The outputs of summer grain are multiplied by the sown areas from sample survey and the yield per unit area.

V. Others

The data in Gansu, Ningxia, and Xinjiang are preliminary due to later mature for the spring wheat.
