National cotton production data released by the National Bureau of Statistics show that the national cotton production in 2020 was 5.910 million tons, an increase of 21,000 tons or 0.4% over the previous year.
1. The national cotton sown area has declined
The national cotton sown area in 2020 was 31.699 million hectares (47.548 million acres), a decrease of 169.4 thousand hectares compared with the previous year. Hectares (2.541 million acres), down 5.1%. In terms of regions, Xinjiang, my country’s largest cotton-producing region, rationally guides cotton production in accordance with the principle of “controlling area, improving quality and efficiency”. The cotton sown area is 25.019 million hectares (37.529 million acres), a decrease of 386,000 hectares (579,000 acres) compared with the previous year. acres), down 1.5%. Affected by factors such as planting efficiency and agricultural structure adjustment, the cotton sown area in other cotton areas has declined. The sown area of cotton areas in the Yangtze River Basin [Note 1] was 2.838 million hectares (4.257 million acres), a decrease of 567,000 hectares (850,000 acres) or 16.6% from the previous year; the sown area of cotton areas in the Yellow River Basin [Note 2] was 358.9 thousand acres. hectares (5.383 million acres), a decrease of 699,000 hectares (1.049 million acres) from the previous year, a decrease of 16.3%.
2. The national cotton yield per unit area has increased
The national cotton output per unit area in 2020 was 1864.5 kg/ha (124.3 kg/mu), which was The annual increase was 100.9 kg/ha (6.7 kg/mu), an increase of 5.7%. Xinjiang’s cotton area has relatively suitable climate conditions, less pests and diseases, and good cotton growth. The cotton yield per unit area is 2062.7 kg/ha (137.5 kg/mu), an increase of 93.8 kg/ha (6.3 kg/mu) over the previous year, an increase of 4.8%. %. Therefore, Xinjiang’s cotton output increased by 159,000 tons compared with the previous year, an increase of 3.2%. Due to the impact of floods in the Yangtze River Basin cotton area, the cotton output per unit area was 1011.1 kg/ha (67.4 kg/mu), a decrease of 53.4 kg/ha (3.6 kg/mu) or 5.0% from the previous year; the unit area of the Yellow River Basin cotton area The yield was 1175.0 kg/ha (78.3 kg/mu), an increase of 57.3 kg/ha (3.8 kg/mu) over the previous year, an increase of 5.1%.
Note:
[1] The Yangtze River Basin cotton area includes 5 provinces: Jiangsu, Anhui, Jiangxi, Hubei and Hunan.
[2] The cotton area in the Yellow River Basin includes 6 provinces (cities): Tianjin, Hebei, Shanxi, Shandong, Henan and Shaanxi.
Announcement of the National Bureau of Statistics on Cotton Production in 2020
Based on statistics from 31 provinces (autonomous regions and municipalities) across the country According to the survey (the cotton sown area in Xinjiang is obtained through remote sensing measurements), the national cotton sown area, unit area yield, and total output in 2020 are as follows:
1. The national cotton sown area is 3,169.9 thousand hectares ( 47.548 million acres), a decrease of 1.694 thousand hectares (2.541 million acres) compared with 2019, a decrease of 5.1%.
2. The national cotton output per unit area is 1,864.5 kg/hectare (124.3 kg/acre), an increase of 100.9 kg/hectare (6.7 kg/acre) compared with 2019, an increase of 5.7%.
3. The country’s total cotton output was 5.910 million tons, an increase of 21,000 tons or 0.4% over 2019.

National and provincial (district, district, City) Cotton Production
Explanation on the cotton yield statistical survey system and methods
The total cotton output in the country is the sum of the cotton output in 31 provinces (autonomous regions and municipalities).
1. Statistical survey methods
The statistical survey of cotton production adopts remote sensing measurement and sampling survey of main production areas, and non-main production areas. A method that combines comprehensive district statistics, and the survey objects include land plots, agricultural production households and business units. Xinjiang obtains the cotton sown area through remote sensing measurement and obtains the yield per unit area through sampling surveys. For cotton in the seven main producing provinces, including Hebei, Jiangsu, Anhui, Shandong, Henan, Hubei, and Hunan, the relevant survey team of the National Bureau of Statistics is responsible for conducting sampling surveys to obtain area and yield data; other regions are approved by the statistics bureaus of each province (autonomous region, municipality) Comprehensive statistics and acquisition of cotton area and yield data.
The sample survey targets in the seven main cotton-producing provinces (Hebei, Jiangsu, Anhui, Shandong, Henan, Hubei, and Hunan) are agricultural production and operation households, and the provinces are used as the overall selection The survey was conducted on representative village groups, farmers and plots. The sown area survey was conducted on all cotton sown areas in the sample points at the time of the survey to estimate the actual cotton sown area. The yield per unit area survey uses the method of household yield measurement to estimate the yield per unit area.
Since 2014, the National Bureau of Statistics has carried out cotton remote sensing measurements in Xinjiang. Through high and medium spatial resolution multi-temporal satellite remote sensing images combined with ground sampling surveys, measurements have been obtained. Cotton sown area in Xinjiang.
The cotton sown area obtained through Xinjiang cotton remote sensing measurements and sampling surveys in seven major cotton-producing provinces accounts for more than 97% of the country’s total cotton area.
2. Survey samples
The field survey of Xinjiang cotton remote sensing measurement includes more than 2,000 samples and a total of more than 500,000 acres of survey land. ; Seven major cotton-producing provinces selected more than 700 villager groups from survey counties in more than 100 countries and conducted sampling surveys in more than 100,000 plots. The cotton yield per unit area was investigated among nearly 1,000 villager groups and nearly 10,000 farmers across the country.
3. Actual measurement method
In accordance with the “Agriculture, Forestry, Animal Husbandry and Fishery Statistical Reporting System”, the cotton yield survey per unit area adopts field measurements. and the method of home birth measurement.
Field measurements are carried out in randomly selected area survey sample points. When the cotton maturity period is approaching, the area in the sample points is measured.The yield of all plots is estimated, and five representative plots are selected as the measured plots according to the yield level of the plots through cumulative sorting by area and then equidistant sampling. After the cotton matures, three small plots are manually selected on site, and the cotton yield per unit area is investigated by counting peaches, weighing, and determining losses.
Household yield measurement is carried out in randomly selected area survey sample points. When the cotton maturity period is approaching, the yield of all households in the sample points is estimated, and the yield is obtained based on the estimated yield. The average yield level of each household is calculated based on the yield of each plot; after the cotton matures, 10 households are selected through the cumulative equidistant sampling method of the average yield of each household by area. After the cotton picking is completed, the cotton sown area of the surveyed household is measured. , harvest volume, sales volume, storage volume, self-use volume, etc. are registered to calculate the yield level. Each survey team of the National Bureau of Statistics estimates the average output per unit area of the province (district, city) based on the yield per unit area of the selected sample plots. </p
