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 from abroad the medicines for suppressing buds, such as Flumetralin, Maleichdrazide, and Pendimethalin. Field management has its own characteristics of bud suppression effects, but the price is relatively high (more than 13 yuan / mu), and they are all chemically synthesized preparations. Using this kind of chemically synthesized bud suppressors, some chemical substances remain in the tobacco leaves and soil, which is harmful to flue-cured tobacco. The impact on quality, residual toxicity, environmental and soil pollution and other issues have not been resolved
[0003] After the axillary buds of vegetables and flowers occur, traditional manual bud removal is also used, which is time-consuming and ineffective

preparation example Construction

[0029] 1, the preparation of this natural biological anti-sprouting agent

[0030] The preparation method of the natural biological anti-sprouting agent is basically the same as the preparation method described in (1) in the summary of the invention. in:

[0031] The collected Botrytis cinerea persr fungal virus damage samples come from strawberry, sour papaya, flowers, lettuce and other plants.

[0032] 2. The application of this natural sprout inhibitor

[0033] After the natural sprout suppressant is prepared, it can be dripped, poured in a cup or sprayed in a conventional way, so as to suppress the crazy growth of tobacco buds and obtain good results. The efficacy period in the field is 30-40 days. The sprout inhibitor can also be used for other plants, such as flowers and vegetables, to regulate the growth of crops, improve the quality and increase the yield.

Embodiment 1

[0034] Embodiment 1: (for suppressing bud of tobacco)

[0035] Crude extract obtained by fermentation (natural p-hydroxyphenethyl alcohol and phenylethyl alcohol) 10.0 g

[0036] Medical ethanol (95%) 50ml

[0037] 950ml water

[0038] This is 1000 milliliters of biological tobacco sprout suppressant application solution containing hydroxyphenylethyl alcohol and 0.5% of phenylethyl alcohol. After being applied in a drip manner, the average sprout suppression rate can reach 93%-94%.

Embodiment 2

[0039] Embodiment 2 (for potato)

[0040] Crude extract obtained by fermentation (natural p-hydroxyphenethyl alcohol and phenylethyl alcohol) 8.0 g

[0041] Medical ethanol (95%) 40ml

[0042] 960ml water

[0043] This is 1000 milliliters of bio-type vegetable sprout inhibitor application solution containing hydroxyphenylethyl alcohol and 0.4% phenylethyl alcohol. After spraying, the potato germination is inhibited by more than 93%.

Abstract

The invention relates to a biological anti-sprouting agent and its use, wherein the anti-sprouting agent is prepared from biological strains through the steps of enlarged culture and fermentation, solvent extraction, concentration, separation and purification. The bacterial strain has a systematic name of Botrytis cinerea, its active constituents include natural tyrosol and phenethylol wherein the contents are 25-30% and 22-25%.

Description

Technical field: [0001] The invention relates to a biological sprout inhibitor and its application, belonging to the field of biological technology. Background technique: [0002] Tobacco leaves are planted in a large area in western my country, and the economic benefits are obvious. However, after capping and pruning in the field management every year, traditional manual bud removal is time-consuming and tiring, and the labor investment is huge, and new buds will grow again not long after the axillary buds are removed. In order to improve the output and quality of tobacco leaf products and reduce labor input, my country has successively purchased from abroad the medicines for suppressing buds, such as Flumetralin, Maleichdrazide, and Pendimethalin. Field management has its own characteristics of bud suppression effects, but the price is relatively high (more than 13 yuan / mu), and they are all chemically synthesized preparations. Using this kind of chemically synthesized bud...
