Investigation on cotton planting and growth in China (may 2021)

?

At the end of May 2021, the cotton farmers branch of China Cotton Association investigated the cotton planting progress and growth of 2306 fixed-point farmers in 12 provinces and cities in the mainland and Xinjiang Autonomous Region. The results showed that as of May 31, the national cotton planting progress was 99.75%, 0.19 percentage points faster than that of the same period of the previous year. The sowing in Xinjiang and the Yellow River basins was completed, and the sowing progress in the Yangtze River Basin was 96.37%, It was 1.11 percentage points faster than that of the previous year. Nearly half of cotton in Xinjiang is in 6-8 true leaf stage, and more than half of cotton in Yellow River Basin and Yangtze River Basin is in 4-5 true leaf stage. According to the weighted average of cotton planting area of the surveyed cotton farmers, the cotton planting area in China was 43.3657 million mu, a year-on-year decrease of 5.66%, and the decrease rate was 1.51 percentage points larger than that in the previous period.

The overall growth of cotton in China was worse than that of last year, and its growth was slower than that of the same period of last year, and the occurrence of diseases and insect pests in different regions was relatively light. Light, temperature and water match well in most cotton areas in China, which is favorable for cotton growth; Drought, gale and rainfall weather occurred in some areas, which was unfavorable to cotton seedling growth. Seedling Damping off and Fusarium wilt were found in some areas of Hebei, Hubei and Jiangsu. According to the survey, 43.84% of cotton seedlings in China are in 6-8 true leaf stage, which is 6.31% less than that of the same period of last year. The occurrence degree of diseases and insect pests was generally light, of which 65.91% were mild diseases, which was 23.04% less than that of last year; 54%, 8. 91% less than the previous year. Among the surveyed households, 17.30% thought that the growth was better, 26.70% less than the same period last year, and 60.31% thought that the growth was poor, 41.26% higher than that of last year.

This year, cotton growth in Xinjiang is relatively lagging behind, and the growth of cotton seedlings is worse than that of last year. According to the survey results, by the end of May, the proportion of cotton growing to 6-8 true leaf stage accounted for 48.63%, which decreased by 6.78 percentage points year on year. In May, the temperature in most cotton areas was higher, which was favorable for cotton seedling growth. However, the windy sand weather at the beginning of the month and the severe convective weather in the middle of the month are unfavorable to the growth of cotton seedlings in some areas, especially providing favorable conditions for the migration and reproduction of cotton aphids. Among the surveyed households, 65.00% of them thought that the disease was mild, with a year-on-year decrease of 25.51%; 76.82% of the cotton fields suffered less insect pests, with a decrease of 7.48% over the same period of last year; 66.35% of the respondents thought that the growth was poor, only 13.04% thought that the growth was better. Affected by the wind disaster, some cotton farmers changed to corn. The actual planting area in Xinjiang was 36.8333 million mu, an increase of 0.49% year-on-year, and the growth rate decreased by 0.13% compared with the previous period.

In the cotton area of the Yellow River Basin, the weather is dry and windy, which has a certain impact on cotton growth. Low temperature weather also occurred in the cotton areas of Hebei and Shandong, which caused some cotton fields to suffer from freezing damage, and the growth of cotton fields was significantly lower than that of last year. By the end of May, the sowing (planting) progress of the basin was 100%, 0.1 percentage point faster than the same period of last year, accounting for 30.60% in the 6th-8th true leaf stage, with a year-on-year decrease of 20.07%; 43.53% of them thought that the growth was better, with a year-on-year decrease of 13.93 percentage points. The incidence of Damping off and Fusarium wilt was slight, accounting for 62.31%, with a year-on-year decrease of 15.27 percentage points; 47.15% of the total pests occurred, with a decrease of 25.40% over the same period of last year, mainly due to natural drought, such as aphids and mirid bugs. The actual sown area of the basin increased slightly compared with the previous forecast, and the actual sown area was 3.3378 million mu, a year-on-year decrease of 32.82%, and the decrease rate was narrowed by 0.38%.

There are many rainy days in the Yangtze River Basin, and the meteorological conditions are generally not conducive to the growth of cotton seedlings. Due to the high humidity in the field, the cotton seedlings grow slowly under waterlogging, and the growth of cotton seedlings is not good. By the end of May, the sowing (planting) progress was 96.37%, 1.11 percentage points higher than that of the same period last year. The seedling age was generally lower than that of the same period last year. 69.60% of the seedlings were in the 4TH-5TH true leaf stage, with a year-on-year decrease of 10.72%; 93% of them were in the 6th - 8th true leaf stage, with a year-on-year decrease of 2.98%. 38.27% thought that the growth was better, with a year-on-year decrease of 15.42%. The incidence of mild diseases accounted for 81.48%, with a year-on-year decrease of 6.67 percentage points; 77.47% of the cases suffered from mild insect pests, with a decrease of 10.54% over the same period of last year, mainly due to a small number of aphids, red spiders and ground tigers. The actual planting area of the basin was reduced compared with the expected, and the actual planting area was 2.9816 million mu, a year-on-year decrease of 25.09%, and the decrease rate was 1.19 percentage points larger than the previous period.
