The lack of potassium in cotton causes yellow spots between the green veins, which then turn brown. The leaves then shrink, become brittle, turn reddish-brown and fall off, and the cotton bolls are relatively thin and prone to premature aging. Control methods: The absorption of potassium by cotton during the whole growth period is generally less in the early stage and more in the middle and later stages. The absorption of potassium after flowering accounts for about 80% of the whole growth period. Therefore, about 12.5 kg of potassium fertilizer should be applied per mu of cotton field. Bud stage topdressing about 7.5 kilograms, in the middle and late can be appropriate to spray potassium dihydrogen phosphate and other potash, spray once every 7 to 10 days, and even spray about 3 times.
