Embodiment

[0021] Tobacco bud suppression work was carried out in a tobacco cultivation field. First, mix flour and water in a pot according to the mass ratio of 1:8, heat to 100°C in an electric furnace with a power of 500W, and boil for 2 minutes to obtain a paste, which is used as a carrier; urea is used as an active substance for removing buds, urea The sprout inhibitor is prepared by preparing the mass ratio of the powder and the paste at a ratio of 1:1.

[0022] Then carry out suppressing bud preparation, select the tobacco strain that has tobacco bud to take place as suppressing bud as processing object, carry out listing mark to processing tobacco bud, prepare suppressing bud;

[0023] On sunny days, for the tobacco buds growing on the listed tobacco plants, use the spare sprout inhibitor urea slurry to directly smear the tobacco buds to form a ring-shaped slurry. The buds smeared with germ inhibitor urea slurry became water-soaked on the same day, began to dehydrate and shrink,...

Abstract

Provided is urea paste tobacco suckercide. According to the suckercide, urea serves as bud removal active matter, paste serves as a carrier, and the suckercide is prepared from urea powder and the paste according to the mass ratio of 1:1. The paste is a pasty body formed in the way that flour and water are mixed in a pot according to the mass ratio of 1:8, and then the mixture is heated to 100 DEG C through an electric stove with the power of 500 W and boiled for 2 min. According to the applied technology, the suckercide is firstly prepared, then sprouting inhibition preparation is carried out, and a tobacco plant with tobacco sprouts emerging is selected as a treatment object; a row brush is dipped in urea paste prepared from the urea powder and the paste according to the proportion of 1:1 to directly smear the tobacco sprouts to form annular pesticide paste; checking is carried out once every 3-5 d after treatment, newly-grown tobacco sprouts are subjected to paste coating and sprout removal, and the aim of sprout inhibiting is achieved. The urea paste tobacco suckercide is harmless to people and livestock and obvious in effect, the tobacco sprouts wither to fall off after being smeared, consumption of potassium nutrients by the tobacco sprouts is reduced, and tobacco leave pesticide residues of chemical sprout removal are removed. The urea paste tobacco suckercide is suitable for all tobacco planting farmers and departments.

Description

technical field [0001] The invention belongs to a sprout suppressant used in tobacco cultivation management, specifically, belongs to a sprout suppressor used in field production of tobacco. Background technique [0002] It is well known that tobacco plants need to suppress or eliminate the growth of tobacco buds during tobacco cultivation. The manual wiping and bud suppression used in the past inevitably provided a transmission route for the pathogen to spread the disease of the virus. At the same time, there are many varieties of tobacco chemical sprout inhibitors, although they are convenient to apply, their residues make tobacco leaves unsafe for smoking. Chemical bud removal itself causes pesticide residues in tobacco leaves; side buds occur due to unsatisfactory bud removal effect, and the subsequent flower bud growth advantage consumes potassium nutrition. [0003] In terms of tobacco bud suppression technology, emerging technology methods emerge in endlessly. Afte...
