Seedling raising method for flue-cured tobacco

Abstract

The invention discloses a seedling raising method for flue-cured tobacco and belongs to the field of tobacco planting. The method comprises several steps such as carrying out disinfection, carrying out substrate loading, carrying out sowing, carrying out fertilizer application, carrying out humiture management and seedling raising house management and carrying out leaf cutting. According to the method, during specific implementation, two stages of seed sowing and seedling raising are adopted, the sowing time interval of the two stages is 10 to 15 days, and the time for reaching transplanting standards after the sowing of a second stage is only 3 to 5 days behindhand that of a first stage, so that tobacco seedlings cultivated in the first stage can be used during primary-stage transplanting, tobacco seedlings cultivated in the second stage are used during later-stage transplanting, and the condition that the tobacco seedlings are all sound and healthy seedlings reaching standards for shaft-kiln-type young seedling transplantation during transplanting is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco planting, and relates to a method for raising seedlings by floating. Specifically, it is a method for raising seedlings by floating based on the technique of "well-kiln-type seedling transplanting" widely promoted in southwest tobacco areas. Background technique [0002] Tobacco seedlings are the basis of tobacco field production, and seedling cultivation is an important part of flue-cured tobacco production. The goal is to provide timely, sufficient, robust and neat tobacco seedlings. Since the cultivation of tobacco, tobacco seedling cultivation has gone through from traditional seedling cultivation to now widely used nutrient blocks, nutrient pots, and nutrient bag artificial planting seedlings, and the tobacco seedling cultivation technology has been greatly improved. But these seedling raising methods are all based on soil, from sowing, emergence and tobacco seedling growth are all...

Problems solved by technology

[0008] However, "well kiln type seedling transplanting" needs to punch deep holes on the ridge surface with a puncher, and the punching efficiency is low, so that the transplanting time of tobacco seedlings is relatively slow. Sowing is completed within 2 days, so that the mature seedlings must be transplanted as soon as possible when the tobacco seedlings emerge. Therefore, on the basis of the "well-kiln-style seedling transplanting" technology, large-scale transplanting can easily cause tobacco seedlings transplanted in the early stage. It is strong seedlings and healthy seedlings, and weak seedlings and diseased seedlings are transplanted later, which will eventually lead to a decline in the yield and quality of tobacco leaves, and the income of tobacco farmers and fiscal taxes will decrease
