The invention provides a high-yield cultivation method for planting a precocious upland cotton variety in a precocious cotton area, in order to solve the problem of greatly reduced output caused by the windstorm disaster in a southern Xinjiang precocious cotton area or the precocious and middle-mature varieties after late
sowing is performed. Different from the traditional cultivation method for the precocious and middle-mature varieties, the high-yield cultivation method is characterized in that: 1) the
sowing time is delayed for 10-25 days; 2) the
sowing density is increased by 1000 strainsper mu; 3)
topping is performed before and after July 20, the
topping time is delayed for 8-12 days, the number of leaved fruit spurs is increased to 1-2 and the
stem length is increased to 5-10cm; 4) after
topping, the chemical regulating times is changed into two from one, the elongation of the top fruit spurs is boosted, the number of the coped buds and the
bud yield are increased; and 5) the pre-
frost yield rate is increased from 95% to above 98%. According to the high-yield cultivation method provided by the invention, the output of cotton is not reduced by the after-culture or late-culture, the output of pre-
frost lint is slightly increased, the level of the lint is increased and the income of a cotton planter is increased.
