Flue-cured tobacco wide-narrow row high-low ridge planting method

Abstract

The invention provides a flue-cured tobacco wide-narrow row high-low ridge planting method. According to the method, plants are distributed alternatively in wide and narrow rows and high and low ridges and plant distance is determined, wherein the row distance of the wide rows is 110-120 cm, the row distance of the narrow rows is 75-95 cm, the height of wide row ridges is 25-30 cm, the width of the ridge surfaces of the wide row ridges is 60-80 cm, the height of narrow row ridges is 10-20 cm, and the width of the ridge surfaces of the narrow row ridges is 30-40 cm. The aim of optimizing flue-cured tobacco group structures is achieved, ventilation and light-permeable conditions of tobacco leaves on the upper portion and on the lower portion are improved, temperature and humidity conditions of soil are adjusted, and disease and pest infection of flue-cured tobacco is effectively prevented.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of flue-cured tobacco planting, and in particular relates to a planting method for optimizing the planting group structure of flue-cured tobacco, in particular to a planting method for wide and narrow rows of flue-cured tobacco with high and low ridges. Background technique: [0003] At present, in order to improve the quality of tobacco leaves, flue-cured tobacco production in the tobacco area implements specialized centralized seedling cultivation, promotes floating seedling cultivation, shallow water seedling cultivation and artificial planting seedling cultivation; implements single-row high ridges, first applies enough base fertilizer, and then ridges. The ridge body is required to be full and straight, the width of the ridge bottom is 80-90cm, the width of the ridge surface is 60-70cm, the height of the ridge body is more than 25cm in the dry soil, and the height of the ridge body is more t...

AI Technical Summary

Problems solved by technology

[0004]1. There are more large tobacco trees and less medium tobacco trees, which affects the appearance and internal quality of tobacco leaves

[0005]2. The group structure of the tobacco field is not good, the lower smoke ventilation and light transmission conditions are poor, the tobacco leaves have weather spots, many false ripe leaves, and the yield and quality are poor; the upper leaves are too long , too wide, too thick, poor usability and quality

[0006]3. The upper leaves mature late and take a long time, and many of them mature after autumn, which affects the normal maturity and quality of tobacco leaves, and there are many leaf spot diseases

[0007]4. Row spacing and ridge height are the same standard, and are easily affected by natural disasters such as drought and waterlogging

[0008]5. It is not easy to increase the planting density of tobacco leaves

However, the above-mentioned planting method only adopts wide and narrow row planting, and the planting technology combining wide and narrow row with high and low ridge planting has not been reported or applied at home and abroad.
