Fuente: WIPO "tobacco agriculture" The invention belongs to the technical field of tobacco planting and harvesting, and particularly relates to a planting and harvesting method for improving total sugar content of tobacco leaves of tobacco, which comprises the following steps: setting tobacco plant planting density of tobacco plants and setting a tobacco leaf harvesting mode of tobacco leaves of tobacco; the planting density of the tobacco plants of the tobacco is 900-1200 plants per mu; the tobacco leaf harvesting mode is whole-plant harvesting, and each leaf is provided with a stem; experiments show that compared with a conventional planting and harvesting method, the method provided by the invention has the advantages that the total sugar content in the tobacco leaves is remarkably improved, so that the raw material application efficiency of the tobacco leaves of the tobacco-upland tobacco is improved, and the problems that tobacco growers often depend on the previous planting and harvesting experience of the flue-cured tobacco and the total sugar content in the obtained tobacco leaves is too low at present are solved.
