. Recently, Xinjiang cotton harvest has begun. In Manas County, Changji Prefecture, 740,000 acres of cotton are gradually entering the maturity stage. Cotton farmers are seizing the opportunity to begin large-scale mechanized harvesting of new cotton.
Manas County is adjacent to the Tianshan Mountains in the south, with fertile soil and light Rich in hot water soil resources, it is suitable for growing cotton. It is an important cotton producing area in Xinjiang and a national-level high-quality commercial cotton production base.
In 2023, the local cotton planting area will be 740,000 acres. In the 10,000-mu cotton field in Lujiazhuang Village, Hu Town, Liangzhou County, Manas County, three newly introduced cotton harvesting and packaging machines are harvesting cotton. The cotton picking machine can efficiently and quickly separate cotton from the cotton stalk, with a clean picking rate of over 95%. On average, a cotton picker can pick more than 700 acres of cotton every day, which is equivalent to the total labor of 1,000 flower pickers.
In order to ensure the smooth progress of cotton harvest, Xinjiang organized agricultural organizations at all levels Technicians go into the fields to help growers solve technical problems and coordinate harvesting machinery and vehicles. At present, Xinjiang cotton is gradually matured and harvested from north to south, and will enter large-scale harvest after October 5. Xinjiang cotton output is expected to be more than 5 million tons in 2023.
New technologies and new models help Xinjiang’s cotton harvest
In 2023, the Cotton Research Institute of the Chinese Academy of Agricultural Sciences and relevant scientific research forces in Xinjiang will After more than ten years of intensive research and promotion, the new cotton planting technology and model of “widening, early and optimal” have been jointly researched and promoted, providing strong technical support for high cotton yields and harvests.
In Xinjiang, in the past, “low density and early growth” were used to grow cotton. The cotton planting model specifically involves dwarfing plant height, increasing planting density, and promoting early maturation. The “short-density, early-season” model is suitable for Xinjiang’s characteristics of tight water resources and high evaporation, and played a very important role during the hand-picking cotton period.
With the further improvement of large-scale cotton production and mechanization, In particular, machine-picked cotton has developed rapidly. Based on the innovation and development of the traditional “short, dense, early” cotton planting model, a new cotton planting model of “wide, early, high quality” has emerged. Among them, “wide” means that the row spacing is widened, “early” means that the cotton grows early and matures early, and “excellent” means that the raw cotton is of excellent quality. It is a new green, high-quality, efficient and high-yield cotton planting model that adapts to the needs of mechanized cotton harvesting and improved cotton production quality in Xinjiang.
With good seeds, good methods are also needed. The new cotton planting model of “wide, early and excellent” is combined with the new high-quality cotton variety Zhongmian 113 to achieve a complete set of improved varieties and methods.
In order to speed up the promotion of “wide, early and excellent” cotton planting technology, The Cotton Research Institute of the Chinese Academy of Agricultural Sciences has established a promotion and application system of “seed enterprises + technology demonstration households + cotton gins”, with a cumulative promotion area of more than 41 million acres in Xinjiang.
New equipment and new technology for recycling agricultural waste film in cotton fields
In 2023, in the Bortala Mongolian Autonomous Prefecture of Xinjiang, the first comprehensive utilization industrialization project of anhydrous agricultural residual film was implemented. Relying on this project, the first production line in Xinjiang was built to promote the green production of cotton.
Remnant agricultural film may be blown away by the wind or carried by the water flow Entering rivers and lakes will not only affect the quality of soil and water, but also have a profound impact on local ecosystems.
In response to the problem of recycling agricultural film residues in Xinjiang, the Cotton Research Institute of the Chinese Academy of Agricultural Sciences and relevant scientific research units developed a waste film collection and utilization system. Compared with the currently commonly used waste mulch treatment production line, this treatment system does not require water to clean the waste mulch. Instead, it completely separates the mulch, straw, and dust through production processes such as crushing, dry cleaning, and screening, and directly separates the separated waste. The mulch film is processed into plastic products such as logistics pallets, trash cans, and manhole covers that meet national standards, reducing water waste.
