Tobacco plant ligation type minimally-invasive topping-free device and method

Abstract

Disclosed is a tobacco plant ligation type minimally-invasive topping-free device. The tobacco plant ligation type minimally-invasive topping-free device comprises a fixed part and a pressure part, wherein the fixed part can be fixed on a tobacco plant, and the pressure part can pierce the surface of the tobacco plant; and a medicine enters the tobacco plant by piercing the surface of the tobaccoplant through the pressure part. A tobacco plant ligation type minimally-invasive topping-free method comprises the steps of fixing the upper end, fixing the lower end, and extruding medicine paste; fixing the upper end, fixing a fixing ring at the top end of the tobacco plant, fixing the lower end, fixing a pressure ring on the tobacco plant at the lower end of the fixing ring, and puncturing thetobacco plant by the pressure ring; and pressing the medicine paste, so that medicine liquid or medicine powder which flows out of the inner surface of the medicine paste enters the opening of the tobacco plant pierced by the pressure ring. The device can be quickly fixed at the top end of the tobacco plant, is high in fixing efficiency, free of topping and good in bud inhibition effect, is smallin damage to the plants, reduces the dip infection of germs, and can be suitable for plants needing to be topping up or needing to block the branch rods, so long as the test achieves the required effect.

Description

technical field [0001] The invention relates to the field of tobacco planting, in particular to a tobacco plant ligation type minimally invasive topping-free device and method. Background technique [0002] Tobacco topping refers to picking off the young flower buds or inflorescences at the top of the tobacco plant when the tobacco plant grows vigorously to the mature stage, so as to control the growth advantage at the top of the tobacco plant. Because tobacco plants have apical dominance, apical buds grow preferentially, which affects the quality of tobacco leaves. However, after topping, the apical dominance is removed, which will promote the growth of axillary buds and affect the quality of tobacco leaves. Tobacco bud wiping refers to erasing the branches (tobacco branches) that germinate from the stem of the tobacco plant; tobacco chemical bud suppression refers to the application of auxin substances to the side buds to inhibit the growth of side buds and improve the yie...

Problems solved by technology

Second, more serious wounds or wounds

After the topping advantage is lost, a large number of axillary buds of tobacco plants will be promoted within a certain period of time, which requires manual wiping and chemical bud suppression, which may cause residual bud suppressants, and requires a lot of labor for field operations, and the labor intensity is relatively high. According to statistics Topping (including fireworks removal) requires 0.33 per mu of labor, and wiping and chemical bud suppression require 0.33 per mu. Since general chemical bud suppression needs to be manually wiped again after 1 month, the labor for the two links is about 0.7

Fifth, it is difficult to control the number of leaves left, which may easily lead to a decrease in the quality of the upper leaves. Due to climate reasons, etc., there may be deviations in the judgment of the residual nutrient supply in the soil. It is not easy to control the number of leaves left during topping. The upper leaves grow violently or even turn over, which affects the use value. If the number of remaining leaves is too large, the upper leaves may not open due to insufficient fertilizer supply, the leaves are small, and the economic value is low.

Sixth, there is a risk of residual sprout inhibitors. Generally, the lower leaves need to be harvested when the sprout inhibitors are applied, and the time interval of application is short, so it is very easy for pesticide residues to exceed the limit or exceed the standard.

[0005] In recent years, a series of topping technology improvements have been carried out in tobacco leaf producing areas, mainly in the following aspects: First, carry out bagging to avoid light, use colored or dark plastic bags to cover the inflorescences, and avoid light to reduce photosynthesis, which can effectively inhibit the topping. Dominance, but lateral bud dominance is not eradicated
