Chemical topping and later-period management method for Xinjiang early-medium ripening upland cotton

Abstract

The invention discloses a chemical topping and later-period management method for Xinjiang early-medium ripening upland cotton, and belongs to the technical field of agriculture. The invention discloses a chemical topping and later-period management method for Xinjiang early-medium ripening upland cotton. The method comprises the steps of chemical topping, pesticide spraying requirements, pesticide selection and pesticide dosage, field management in the later period of chemical topping of the Xinjiang early-medium ripening upland cotton, flowering and boll-forming period management and boll opening period management. According to the chemical topping and later-period management method for the Xinjiang early-medium ripening upland cotton, chemical topping and a chemical topping later-period field management method are combined, and scientific basis and practical guidance are provided for large-area application and popularization of the chemical topping technology in the Xinjiang cotton area.

Description

technical field [0001] The invention relates to the field of agricultural technology, and more specifically relates to a method for chemical topping and post-management of early and mid-maturing upland cotton in Xinjiang. Background technique [0002] Xinjiang is one of the areas with the largest cotton output, the highest fiber quality, and fewer pests and diseases in the cotton area of ​​the country. It is also the most suitable area for planting early and mid-maturing cotton varieties. In 2019, Xinjiang's cotton planting area was 2.5405 million hectares, with an output of 5.002 million tons, accounting for 84.9% of the country's total output. Manual topping is the traditional and main method of cotton topping in Xinjiang. Traditional cotton topping is to manually pinch out the growth point of the main cotton stem, which requires a lot of work and poor timeliness. Now it is increasingly unable to meet the requirements of mechanization and cost-saving and high-efficiency i...

Problems solved by technology

Manual topping is the traditional and main method of cotton topping in Xinjiang. Traditional cotton topping is to manually pinch out the growth point of the main cotton stem, which requires a lot of work and poor timeliness.

Now it is increasingly unable to meet the requirements of mechanization, cost-saving and high-efficiency in the production of early and mid-maturing cotton in Xinjiang, and urgently needs to be replaced by a more advanced topping method.
