Description

Technical Field

[0001] The utility model relates to the technical field of tobacco planting, in particular to a flue-cured tobacco topping and bud removing device. Background Art

[0002] During the cultivation of flue-cured tobacco, it is necessary to regularly remove the top buds to remove the apical dominance and reduce nutrient consumption, thereby increasing the accumulation of carbohydrates in the leaves, the weight per unit leaf area and the dry weight, and improving the yield and quality of tobacco leaves.

[0003] Promote root development and improve fertilizer utilization. Topping and branch removal can promote the germination of secondary roots and increase the depth and density of roots. Due to the increase in root depth and root width, the root's ability to absorb and synthesize water and nutrients is correspondingly increased, so the aboveground part grows well, and the synthesis of nicotine is also enhanced, and the nicotine content in the leaves is increased. Topping is one of the most important agronomic measures to control the nicotine content of tobacco leaves.

[0004] Topping combined with pruning can improve ventilation and light transmission in tobacco fields, reduce air humidity in the fields, and reduce the occurrence of pests and diseases, especially aphids. Topping combined with pruning can remove the young organs where the eggs and larvae of tobacco aphids and pests survive, which can significantly reduce the harm of tobacco aphids and viral diseases transmitted by tobacco aphids.

[0005] Improving the maturity of tobacco leaves Maturity is the central factor of quality; after topping, the tobacco plants avoid unnecessary nutrient consumption, save a lot of nutrients, and improve the nutritional status of the tobacco plants, thereby better supplying the leaves with the nutrients necessary to maintain their life activities, which can extend the life of the leaves and help improve the maturity of the tobacco leaves.

[0006] For example, the utility model with application number 202320617185.5 discloses a portable flue-cured tobacco topping and bud-removing device, which is provided with a piston groove, a piston rod and a push block. After topping, press the control button with your finger. At this time, the output end of the micromotor drives the screw to rotate, so that the push block pushes the piston rod to feed a certain distance, and then the micromotor is turned off. At the same time, the solenoid valve is opened for a certain time, and then the solenoid valve is closed to replenish the liquid medicine inside the connecting pipe, so that the liquid medicine enters the inside of the applicator head through the insertion tube. However, the topping and bud-removing device similar to the above-mentioned document requires manual mechanical operation to trim the flue-cured tobacco leaves.
