The effect of potash fertilizer is to increase the physiological activity of cotton and increase the utilization rate of nitrogen fertilizer; the second is to promote the growth of cotton roots, stems, leaves and reproductive organs, extend the functional period of leaves, and prevent premature aging; the third is to enhance disease resistance and resistance. In contrast, in the old cotton area can significantly enhance the ability of resistance to blight; Fourth, increase the rate of ringing, increase the weight of the single boll weight and the finger, according to the comparative test, the application of potassium fertilizer than the control, the single plant bell The number is increased by 2 to 3, the boll weight is increased by 0.6 to 1.4 grams, the child finger is increased by 0.25 to 1.3 grams, and the fifth is the increase of production by more than 10%.
The amount of potash used is generally 20-30 pounds per kilogram, and the insect-resistant hybrid cotton is about 60 pounds per kilogram of potash. In the early stage of application of compound fertilizer, the bud period needs to apply 30 kg of potash fertilizer per acre. Of course, all areas can be controlled by the soil, fertility, and climate.
The application of potash fertilizer for many years and more practices has proved that potash fertilizer is generally applied twice as well, once as the base fertilizer, and the second time as head fertilizer (Leaf Fertilizer). Flowering and boll-lining are also effective. When potassium is applied, mixing with organic fertilizers is promoted and the effect will be better.
