The invention discloses a production method for wide-early-superior raw cotton in a cotton region in Northwest China. The method includes the following steps of 1,
fission type elite seed production,wherein variety selection,10-ten-thousand-times
fission type seed
reproduction, and grain selection according to the grain size are conducted; 2, planting in rows with the equal width and conducting the following matching technologies: the variety selection and rational early
sowing technology, the edge film widening and lighting technology, the
sowing row no-covering-soil and film no-covering-soil technology, the appropriate
seedling water dropping technology, the first water late-drop technology, the
plant-
height increasing and appropriate tip
pruning delay technology, and the cotton-flowering and boll-forming
fertilizer re-application technology; 3, an early-
sowing and early-
ripening matching technology; 4, superior raw cotton
quality control technologies which includes the technology of uncovering mulching films in the optimum period and preventing
pollution, the technology of spraying an appropriate amount of disleave agent and ripener in the appropriate period, the technology ofremoving field weeds and foreign matters and the technology of harvesting in the appropriate period. The method is feasible, operation is simple and convenient, conversion from short-dense-early 'getting cotton by temperature' to tapping of the potential of light, temperature and environment resources is achieved, and support is provided for high-yield, high-efficiency and high-quality cotton.
