A kind of medicine and method for effectively alleviating hypophysis after topping of tobacco plants

Abstract

A drug that effectively alleviates the empty stem disease after topping tobacco plants includes tung oil liquid; the method is to apply the drug liquid that is effective for alleviating the empty stem disease after topping tobacco plants directly on the wound surface of the tobacco plants within 4 hours after topping, which can effectively relieve the disease. The hollow stem disease after topping the tobacco plants does not affect the normal growth of the tobacco plants.

Description

technical field [0001] The invention relates to a method for preventing and treating the empty stem disease after topping tobacco plants, in particular to a medicine and a method for effectively alleviating the empty stem disease after topping tobacco plants. Background technique [0002] Tobacco hypostem disease harms 120 species of plants in 57 families including tobacco, cabbage, carrot, celery, cucumber, radish, and potato; the incidence is more serious in the south than in the north; it causes serious damage in some areas. Often mixed with bacterial wilt, causing greater losses, both seedling and adult plant stages can be affected, more than when topping and wiping branches. The onset occurs at the adult plant stage, and the germs mostly invade from the topping fracture, and spread downward along the pith. First, soft rot occurs in the pith tissue, and when it is severe, the pith rots and emits a stench. Bacteria can also invade from wounds in other parts to cause dise...

Problems solved by technology

[0003] Topping is mainly to control the dominance of the top. The flower buds and the lower 1-2 leaves are removed at one time. Generally, steep hand picking or knife cutting is used. After the picking method, the stem section is not neat and the stem pith is squeezed. , easy to accumulate water or be attacked by pathogens, which will increase the occurrence of tobacco hollow stem disease. The section of the stem in the cutting method is slope-shaped, and the wound surface is slightly larger, which is not easy to accumulate water. However, under long-term rainy conditions, the wound on the section is larger and difficult to heal. increased risk of hypophysis
