A tobacco sprout-inhibiting weed-killing agent and an applying method thereof

Abstract

A tobacco sprout-inhibiting weed-killing agent is provided. The sprout-inhibiting weed-killing agent is a NaOH solution having a concentration of 5% by adopting NaOH the purity of which is 100% as a solute and water as a solvent with a mass ratio of the NaOH to the water being 5:95. An applying method includes a step of preparing the sprout-inhibiting weed-killing agent, a step of sprout inhibition preparation, namely a step of selecting tobacco plants with sprouts or a tobacco farm overgrown with weeds as a treating object, a step of directly smearing tobacco sprouts with the NaOH solution having the concentration of 5% with a brush, a step of spraying weeds in the tobacco farm with the NaOH solution having the concentration of 5%, a step of checking every 3-5 days after treatment and coating newly grown sprouts orderly to remove the sprouts, and a step of spraying or manually pulling up weeds not killed which are of a small amount, thus achieving the objective of inhibiting sprouts and killing weeds. The sprout-inhibiting weed-killing agent and the method are advantageous in that the sprout-inhibiting weed-killing agent is safe to human and livestock and has significant sprout inhibiting and weed killing effects, tobacco sprouts wither and drop after being smeared, potassium nutrient consumption of the tobacco sprouts is reduced, tobacco leaf pesticide residues during chemical sprout removing and chemical weed killing are avoided, and the sprout-inhibiting weed-killing agent and the method are suitable for all tobacco planting farmers and units.

Description

technical field [0001] The invention belongs to tobacco cultivation, in particular to a bud-suppressing herbicide used in tobacco cultivation management. Background technique [0002] It is well known that tobacco plants need to suppress or eliminate the growth of tobacco buds during tobacco cultivation. In the past, manual wiping was used to suppress buds, but because manual wiping is more labor-intensive, and it is easy to infect diseases caused by viruses, many smoking areas also use chemical bud suppression. However, there are many varieties of tobacco chemical germ inhibitors, and their residues have always puzzled the safety of tobacco leaf smoking. These problems include: ①Pesticide residues in tobacco leaves caused by chemical bud removal itself; ②The occurrence of lateral buds due to unsatisfactory bud removal effect, enrichment of food for aphids, and the superposition of disease control and insecticides taken after mosaic disease The effect aggravates the pestic...

AI Technical Summary

Problems solved by technology

In the past, manual wiping was used to suppress buds, but because manual wiping is more labor-intensive and prone to infectious diseases caused by viruses, many smoking areas also use chemical bud suppression

However, there are many varieties of tobacco chemical germ inhibitors, and their residues have always plagued the safety of tobacco smoking

These problems include: ①Pesticide residues in tobacco leaves caused by chemical bud removal itself; ②The occurrence of lateral buds due to unsatisfactory bud removal effect, enrichment of food for aphids, and the superposition of disease control and insecticides taken after mosaic disease The effect aggravates the pesticide residues in tobacco leaves; ③The resulting flower bud growth advantage consumes potassium nutrients

Except for 20141041088.X and 201410457718.3, it is not clear whether these methods have chemical drug residues, and the herbicidal effect has not been reported
