Abstract

Abstract:

Through years of research and practice, Xinjiang has formed a "short, dense, and early" cotton cultivation mode based on reasonable dense planting, dwarf plants, and early emergence and early maturity around 1994. The purpose of this mode was to promote early growth, fully utilize the technical methods of film mulching, drip irrigation, chemical regulation, mechanization, and informatization, and combine with cotton varieties, through dense planting and dwarf plants to promote the growth and development of cotton with synchronization of radiation use efficiency, and coordinate the contradiction between individuals and population of cotton. The group effect was used to increase the source and expand the sink to improve the effective photosynthetic area and photosynthetic production capacity, and to overcome adverse environmental impacts, such as low temperature in spring and rapid cooling in autumn. The "short, dense and early" cultivation mode could achieve early cotton maturity, high yield and high quality, which has increased Xinjiang's lint yield per hectare from 511.5 kg in 1981 to 1 200 kg in 1994. Under this mode, a high yield of 1 966.5 kg was achieved in 2019, and the average annual yield increased by more than 7.2%, which provided a mode for China and the world to explore high-yield cultivation modes. This article reviewed the formation and evolution of the "short, dense, early" cultivation mode, focusing on the content and high-yield mechanism of the mode, and prospects for the development of the mode, in order to provide a reference for the continuous innovation of cotton cultivation modes in the future.

Key words: Xinjiang, cotton, short dense early mode, high yield, cultivation technology
