Cotton should pay attention to the application of boron fertilizer

Cotton is sensitive to boron, and the application of boron fertilizer can prevent cotton "bud without flower" disease and increase the rate of bell formation. Where the effective boron content of the soil is less than 0.5% mg/kg, the boron fertilizer should be added, and the base fertilizer should be mixed with 0.5-0.75 kg of boron per mu and organic fertilizer and phosphate fertilizer. For external root spray fertilizer, generally use 0.2% borax solution 50kg per acre, or use gold ground to liquid boron fertilizer or 20% gold ground to dissolve boron fertilizer 50g water 50kg, from the bud stage to the initial flowering stage Apply twice, each time around 7 days.
