Problems solved by technology

[0003] The pit-type transplanting technology is an applicable technology that saves labor, reduces costs, improves quality and increases efficiency, and has been widely promoted. However, after the pit-type transplanting of rice field tobacco strains, the pit walls are easy to harden, especially in the southeast tobacco area. When there is a lot of rain after transplanting, it will affect the growth and development of the root system, resulting in the phenomenon of stiff seedlings after transplanting, which is not conducive to the early growth and rapid growth of tobacco plants.

Abstract

The invention provides a method for promoting the early growth and fast development of well cellar-type transplanted tobacco plants in a rice field. The method includes the steps of firstly, cultivating tobacco seedlings; secondly, preparing nutrient soil, wherein 60-65 parts of mountain soil, 15-20 parts of coal cinder, 15-18 parts of an organic fertilizer, 1-2 parts of a compound fertilizer, 0.5-3 parts of brassin and 0.1-1 part of sodium selenite are weighed and evenly mixed with a calcium magnesium phosphate fertilizer and water after the PH value is adjusted to be 6.5-7.0 to obtain the nutrient soil; thirdly, applying the nutrient soil, wherein the tobacco seedlings are transplanted through a well cellar type transplanting method, 200-300 g of nutrient soil is applied in each well cellar to serve as transplanting dowry soil when the tobacco seedlings are transplanted, and 400-600 g of nutrient soil is applied in each well cellar to serve as after-transplanting soil dressing when the growth point of the tobacco seedlings is 2-3 cm higher than the mouth of the well cellar. The method is simple, can promote the development of root systems and the early growth and fast developmentof the tobacco plants and can improve the quality of tobacco leaves and economic benefits.

Description

Technical field [0001] The invention belongs to the technical field of tobacco planting, and in particular relates to a method for promoting early growth and rapid growth of tobacco plants in paddy fields through cellar transplantation. Background technique [0002] Early growth of tobacco plants plays an important role in improving the regularity, disease resistance, yield quality and industrial availability of tobacco plants in the field. A well-developed root system is the basic condition for achieving early growth and rapid growth of tobacco plants, and root growth depends on the micro-ecological environment conditions in the rhizosphere. Therefore, creating an excellent root growth environment is the key to promoting early growth and rapid growth of flue-cured tobacco. [0003] Well cellar transplanting technology is an applicable technology that saves labor, reduces costs, improves quality and increases efficiency, and has been widely promoted. However, well cellar walls tend...
