Notes:

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

2. The data in Inner Mongolia, Jilin, Heilongjiang, Tibet and Qinghai are vacant due to no summer grain.

Explanation on the summer grain output survey

The data released by 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. 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 summer grain output survey, and finally get the summer grain estimates. The output in 17 provinces takes a share of more than 97 percent over that of national total.

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.

II. 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 is conducted in more than 4000 survey villages and 200 thousand rural households selected in national survey counties (cities). 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, of summer grains are estimated by on-site measurement on the summer wheat, which are conducted in the selected 40 thousand sample land segments from more than 3000 selected survey villages in national survey counties (cities).

III. Output Measurement Method

The on-site measurement on wheat output refers to the investigators in the grass roots, before harvesting, in accordance with Sample Survey System on Agricultural Output, stepping in the field and estimating the output of planting land plots one by one, and ranking them by output, then selecting a certain segments 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.

IV. Others

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