The invention discloses a whole-process mechanized planting method for double-cropping multi-cropping cotton that saves labor, fertilizer, and medicine. Pre-emergence weeding and other operations are completed at one time; the whole process of machine management: no thinning, no seedling replenishment, no pruning, no fork, no topping, fertilizer spraying, pesticide spraying, adjustment, defoliation and ripening use drones for operation; One-time machine collection; 60% labor saving. Reasonable densification, one-time application of special controlled-release fertilizer, and drone spraying, saving 50% of fertilizer. The use of insect-resistant varieties, food lures and biological pesticides, insecticidal lamps, and drone spraying saves 40% of the pesticides. Compared with the conventional technology, this method uses 40% of labor, 50% of chemical fertilizers, 60% of chemical pesticides, and mechanized operation in the whole process under the condition of double-cropping and multi-cropping, and obtains 10% of the cotton yield, which can greatly reduce labor and cost, and reduce excess. The non-point source pollution caused by the use of chemical fertilizers and pesticides will improve the mechanization rate, resource utilization rate and cotton planting benefits. |
