More Information
Summary:The invention belongs to the technical field of crop planting, and particularly relates to a cotton cultivation method suitable for farmland polluted by heavy metal cadmium. The cultivation method comprises the steps of field preparation, cotton sowing, fertilization and chemical regulation. Wherein the step of fertilizing comprises one-time application of the phosphorus-potassium fertilizer in the field preparation period; the nitrogen fertilizer is intensively applied within one week after flowering in the field; the boron fertilizer is used for applying boron on leaf surfaces after cotton topping. According to the cotton cultivation method, absorption of the cotton to the heavy metal cadmium in the flowering and boll-setting period is promoted through modes such as nitrogen fertilizer middle moving, boron fertilizer rear moving and chemical control sealing, the high yield of the cotton is ensured, meanwhile, absorption to the heavy metal cadmium is improved, the cadmium removal amount can be larger than or
