Problems solved by technology

However, after capping and pruning in the field management every year, the traditional manual bud removal is time-consuming and tiring, and the labor investment is huge, and new buds will grow after a short time after removing the axillary buds.
In order to improve the output and quality of tobacco leaf products and reduce labor input, my country has successively purchased Fumetralin and Pendimethalin for bud suppression from abroad. These drugs are used in field management, and their bud suppression effects have their own characteristics. But the price is high (more than 13 yuan / mu), and they are all chemically synthesized dinitroaniline preparations. Using this kind of chemically synthesized sprout inhibitors, some chemical substances will remain in the tobacco leaves and soil, especially the nitrite produced by their decomposition. The impact of nitro compounds on the quality of flue-cured tobacco, the environment and soil pollution has always been an unresolved problem

preparation example Construction

[0029] 1. Preparation of tobacco and vegetable sprout inhibitor

[0030] It is prepared by using commercially purchased industrially produced phenethyl alcohol, or p-hydroxyphenethyl alcohol, or a mixture of more than 95% phenethyl alcohol and p-hydroxyphenethyl alcohol, and adding clear water; the composition of the bud inhibitor is divided into:

[0031] (1) 1-5 grams of phenethyl alcohol and 995-999 milliliters of water;

[0032] (2) 1-5 grams of p-hydroxyphenethyl alcohol, add 995-999 ml of water;

[0033] (3) 2.0-2.5 g of p-hydroxyphenethyl alcohol, 2.0-2.5 g of phenethyl alcohol and 9 95-9 96 ml of water.

[0034] 2. Application of Tobacco and Vegetable Sprouting Agent

[0035] After the natural sprout inhibitor is formulated, conventional drip, cup or spray methods can be used to inhibit the wild growth of tobacco and vegetable axillary buds, and good effects have been received. The field efficacy period is 30-40 days.

Embodiment 1

[0036] Example 1 (for tobacco):

[0037] 5 grams of phenethyl alcohol plus 995 milliliters of water. This is 1000 ml of tobacco sprout suppressant application liquid containing 0.5% phenethyl alcohol. After the application is dripped, the sprout suppression rate can reach 91% on average.

Embodiment 2

[0038] Example 2 (for tobacco):

[0039] Add 5 grams of p-hydroxyphenethyl alcohol to 995 milliliters of water. This is 1000 ml of tobacco sprout inhibitor application solution containing 0.5% p-hydroxyphenethyl alcohol. After the application is dripped, the sprout suppression rate can reach more than 91.5%.

Abstract

A bud suppressing agent of vegetable and tobacco for improving their quality and increasing their yield is proportionally prepared from phenylethanol and / or p-hydroxyphenyl thanol through mixing and dissolving in water.

Description

Technical field: [0001] The invention relates to a tobacco and vegetable sprout inhibitor, belonging to an agricultural sprout inhibitor. Background technique: [0002] Tobacco is planted in a large area in western my country, and the economic benefits are obvious. But after capping and branching in field management every year, traditional manual bud removal is time-consuming and laborious, labor input is huge, and new branch buds will grow soon after the axillary buds are removed. In order to increase the yield and quality of tobacco products and reduce labor input, China has successively purchased F1umetralin (inhibition of buds) and Pendimethalin from abroad. These medicines are used for field management, and their bud suppression effects have their own characteristics. But the price is higher (more than 13 yuan / mu), and they are all chemically synthesized dinitroaniline preparations. Using this kind of chemically synthesized sprout inhibitors, some chemical substances remain ...
