Abstract

The invention discloses a planting method capable of promoting root development of tobacco plants, which comprises the following steps: S1, seedling raising: adding a microbial mixed solution into a floating seedling raising nutrient solution when seedlings emerge for 7-10 days, spraying the microbial mixed solution onto the surfaces of tobacco leaves when the seedlings grow for 25-30 days, and then obtaining to-be-transplanted tobacco seedlings after the seedlings grow for 50 days; s2, transplanting: transplanting the to-be-transplanted tobacco seedlings in the S1 to the finished ridges in a cup-type transplanting manner, S3, topping: spraying a microbial mixed solution to tobacco leaf surfaces 5-7 days after the tobacco seedlings are transplanted, and topping 10-13 days after the tobacco seedlings are transplanted; s4, field management, wherein field watering, weeding and topdressing are conducted on the tobaccos, and weeds, accumulated water and hardening are avoided; s5, tobacco leaf harvesting, wherein after the tobacco leaves are mature, manual harvesting is conducted according to specifications. The method can promote root development and further guarantee growth and development of flue-cured tobacco, and is suitable for tobacco planting.

Description

technical field [0001] The invention belongs to the technical field of tobacco planting, and in particular relates to a planting method capable of promoting the root system development of tobacco plants. Background technique [0002] The root system is the general term for all the roots of a plant. The root system is the main organ for crops to absorb soil nutrients and water. The development of the root system is closely related to the distribution, migration, and consumption of water and nutrients in the soil, and is directly related to the growth and yield formation of the aboveground parts of crops. The spatial distribution of crop roots refers to the direction of the roots in the soil, the horizontal and vertical extension properties, etc., and the formation of crop root morphology is affected by both the environment and genes. Moisture, mineral absorption capacity. [0003] As a fixation organ, an absorption organ and an important synthetic organ, the tobacco root sy...
