Problems solved by technology

Usually in field production, due to factors such as the increase of soil bulk density and the thickening of the plow bottom, it is often difficult for the root system of flue-cured tobacco to pierce and stretch, and there are problems such as insufficient root development of flue-cured tobacco root system and shallow spatial distribution of root system, which lead to the root system’s influence on the dynamic and variable resources in the soil. The ability to explore and absorb is weakened, and the production potential of superior tobacco varieties cannot be fully utilized

Abstract

The invention discloses a flue-cured tobacco cultivation method capable of effectively promoting flue-cured tobacco root growth. The method comprises the steps of tobacco seedling culture, tobacco seedling transplanting and field management. The flue-cured tobacco root growth environment can be effectively improved, proper conditions are provided for elongation growth of flue-cured tobacco roots, the flue-cured tobacco root length density and depth indexes are effectively enlarged, the root structure is optimized, and growth and development of overground parts of flue-cured tobacoo are promoted.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco cultivation, and in particular relates to a flue-cured tobacco cultivation method capable of effectively promoting the root growth of flue-cured tobacco. Background technique [0002] 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] The root system of flue-cured tobacco not only has the function of supporting, absorbing water and nutrients, but also an...
