First, the fertilizer type is unreasonable: diazo fertilizer, phosphate fertilizer, light potassium fertilizer, organic fertilizer and micro-fertilizer. In particular, the proportion of organic fertilizer in the base fertilizer is small, which causes the disease resistance and stress resistance of cotton to decrease, leading to early premature aging, resulting in a decrease in cotton yield and quality.
Second, the amount of fertilization is unreasonable: blindly increase the amount of nitrogen fertilizer applied during production, and mistakenly believe that the higher the amount of fertilizer applied, the higher the yield. It leads to the mid-term madness of cotton, excessive growth of vegetative growth, inhibition of reproductive growth, excessive consumption, causing early premature aging, resulting in reduced cotton yield.
Third, the fertilization period is unreasonable: the cotton field in production is often late, causing cotton greed, the late madness grows prosperous, the pests occur seriously, causing the buds to fall off, resulting in a decline in yield.
Fourth, the fertilization method is unreasonable: some cotton farmers apply top dressing in the small row of ditch, the amount of fertilizer is large and close to the cotton plant, the emergence of fertilizer rooting, causing the cotton root system to be blocked, premature aging and death, affecting yield.
Fifth, contempt for micro-fertilizer spraying: no attention is paid to foliar topdressing in the later stage of growth. Especially in cotton fields with premature aging, the nutrition can't keep up, causing the cotton buds to fall off a lot, affecting the increase of cotton yield.
Fertilization in cotton fields should be done 1. Soil testing formula, balanced fertilization. 2. Control the dosage and master the period. 3. Reduce nitrogen, increase potassium, increase organic fertilizer, and supplement micro-fertilizer.
