< p > project commitment: China < a href= "//www.sjfzxm.com/news/index_c.asp" > Cotton Association < /a > cotton farmers cooperative association, Xinjiang Huatai Cotton Professional Cooperative < /p >
< p > monitoring objects: 13 cotton producing provinces, cities and districts, 2724 cotton growers < /p >
< p > May 2013, the cotton association of China Cotton Association and Xinjiang Huatai Cotton Professional Cooperative respectively conducted 2724 cotton growers in 12 provinces in the mainland and 310 counties (cities and regiments) in Xinjiang autonomous region in 2013, and checked the sowing area of cotton planting, the seeding progress of cotton and the growth of cotton seedlings. The results showed that: in May, the meteorological conditions of most cotton regions in China were suitable for cotton seedling growth, and cotton seeding was almost over. According to the weighted average of cotton planting area of cotton farmers surveyed, the area of cotton planting in the whole country is 68 million 220 thousand mu, which is 6.7% lower than that in 2012. By the end of May, the progress of cotton sowing to the field in the whole country was 96.8%, which was the same as that of the same period of last year. The planting of the the Yellow River River Basin and Xinjiang cotton region was all over. The cotton is in the seedling stage to third and fifth true leaf stage. The local cotton area in Xinjiang has begun to bud. The occurrence of pests and diseases is relatively mild, and the overall seedling situation is slightly worse than the same period last year. < /p >
< p > the Yellow River basin < a href= "//www.sjfzxm.com/news/" > cotton sowing > /a >, transplanting all finished, the progress is basically the same as last year. Most of the cotton growing areas in the early stage of the basin are more drought, which is unfavorable for the spring sowing and seedling growth. The cotton seedlings are smaller, and the early growth of cotton is not vigorous and the overall seedling condition is poor. In the later stage, there are several precipitation processes, the soil moisture content is obviously improved, and the cotton seedling grows better, but there are waterlogging disasters in some cotton areas. By the end of May, cotton seedlings were generally small and uneven, with seven leaves and one heart, and only two leaves. The survey households with 6-8 leaves and one heart accounted for 24% of the total survey households, representing a decrease of 43.7 percentage points compared with that of the total household survey. The age of the seedlings accounted for about half of the 4-5 leaves and one heart, while the seedling age of 2-3 leaves and one heart accounted for nearly 1/3. The authors believe that the 33.1% of the total surveyed households were better than those of the total household survey, which decreased by 33.7 percentage points compared with that of the previous year. Nearly 20% of the survey households thought the seedlings were relatively poor, which increased 6.4 percentage points compared to the same period last year. The occurrence of cotton seedling diseases and insect pests is generally light. The surveyed households accounted for 83.2% of the disease, which was 4.3 percentage points lower than that of the previous year. The proportion of insect pests was 70.1%, an increase of 4.3 percentage points over the same period. < /p >
< p > in the Yangtze River Basin, drought and waterlogging were uneven in May, some cotton areas were dry, < a href= "//www.sjfzxm.com/news/" > cotton > /a > late; heavy rain occurred in some cotton areas, and cotton fields suffered waterlogging disasters. At the same time, the late rainy weather caused the rape and wheat ripening to slow down, which affected the transplanting progress of cotton. Among them, sunny weather in Hubei and Hunan, light and temperature conditions and soil moisture are more suitable for cotton transplanting and cotton seedling growth; Jiangsu and Jiangxi have more precipitation and slower transplanting progress; cotton growth is affected by rain after drought in Anhui. By the end of May, the pace of transplanting to Datian was only 87.3%, slightly slower than the same period last year. Affected by meteorological conditions, the growth of cotton seedlings in the river basin was slower than that in the same period last year. As of the end of May, the survey households with 6-8 leaves and one heart accounted for 19% of the total household survey, which slowed down by 7 percentage points compared with the same period last year, most of which were 4-5 leaves and one mind. The growth of cotton seedlings was slightly worse than that of the same period last year, which accounted for 44.4% of the total survey households, which was 3.6 percentage points lower than the same period last year. The occurrence of cotton seedling diseases and insect pests was relatively low. The surveyed households accounted for 66.6% of the disease, which was 2 percentage points lower than that of the previous year. The disease was mainly caused by Damping off and Damping off. 62.4% of the insect pests were considered lighter, 5.4 percentage points higher than the same period last year. < /p >
< p > greater part of Xinjiang > a href= "//www.sjfzxm.com" > cotton area < /a > light and heat condition is better, but slightly worse than the same period last year, basically suitable for cotton growth and development. During the month, some cotton areas were attacked by rainstorms, strong winds and hailstones, which led to more than 100 thousand acres of cotton being damaged. Since the sowing period, the temperature in Xinjiang is lower than that in the same period last year. The delay of cotton seedling topping may affect the final yield. In the north of Xinjiang, it continued to rain, and cotton growth was affected. Some cotton fields with good moisture retention were replanted because of the rotten cotton seedling roots. By the end of May, the survey households with 6-8 leaves and one heart accounted for 29.1% of the total survey households, representing a decrease of 8.5 percentage points compared with the same period last year. The seedling age was 69.3% of the total 4-5 leaves, and 1.6% of the seedling age was 2-3 leaf one heart. It is believed that the 74.5% of the total surveyed households are better than those of the same period last year. The cotton seedling disease is lighter and the insect pest is heavier. The surveyed households account for 68.6% of the disease, which is basically the same as that of the same period last year. The proportion of pests is 36.5%, which is 2 percentage points higher than that of the same period last year. < /p >
