Description

A portable flue-cured tobacco topping device

technical field

The utility model relates to the technical field of flue-cured tobacco strain topping, in particular to a portable flue-cured tobacco topping device.

Background technique

Tobacco is a kind of non-edible foliar economic crops. Most of the products produced in large areas are leaves. After the tobacco plants enter the mature stage and flower buds appear, the entire tobacco plant begins to change from vegetative growth to reproductive growth, which will lead to a large amount of vegetative growth. The inflorescence flowing to the top of the tobacco plant will affect the growth of the tobacco leaves and reduce the yield and quality of the tobacco leaves. Therefore, the key points of management during the maturity stage of the tobacco plants are to control the transformation of the tobacco plants from vegetative growth to reproductive growth. Topping techniques are commonly used to eliminate top dominance, prevent reproductive growth, increase the accumulation of dry matter in tobacco leaves and the single leaf weight of tobacco plants, so as to achieve the purpose of improving the yield and quality of tobacco leaves.

At present, the topping technology adopted in my country is mainly manual topping and chemical topping, but manual topping requires tobacco farmers to pinch off the fireworks one by one, which consumes a lot of time and labor, and the orderliness after topping is not impressive. Topping is easy to have adverse effects on the quality of tobacco leaves, smoking safety and the natural environment of tobacco fields. A few areas have tried to use mechanical topping. Although the efficiency has been significantly improved, it will be difficult to move and disassemble in the complex terrain of the tobacco field. These problems seriously affect the enthusiasm of tobacco farmers and affect the mechanical topping. top promotion rate. For this reason, it is necessary to invent a high-quality, convenient and efficient tobacco topping device.
