Problems solved by technology

At present, the method of chemical germination suppression mainly adopts the method of cup spraying or smearing the sprouting inhibitor, and the exposure of the sprouting inhibitor to the air is not only not conducive to the effective absorption of the sprouting inhibitor, but also increases the dosage of the sprouting inhibitor; Sprout agent splashes on the tobacco leaves, affecting the safety of the tobacco leaves
In case of rainy weather after the application of the sprout inhibitor, the effect of the sprout inhibitor will be greatly reduced under the washing of the rain; moreover, the sprout inhibitor will also adhere to the tobacco leaves or flow into the soil, resulting in excessive pesticide residues in the tobacco leaves and soil

Embodiment 1

[0019] 1) Use purified water to dilute the systemic or local systemic sprout inhibitor to the concentration range specified in the instructions, among which the systemic or local systemic sprout inhibitor is currently recommended by China Tobacco Tobacco Leaf Company;

[0020] 2) Spray the diluted sprout inhibitor solution evenly inside the plastic bag, the dosage of each bag is 10-15ml, the thickness of the selected plastic bag is 0.018-0.020mm, the length is 45-50cm, and the width is 25-30cm;

[0021] 3) When the flower buds of the tobacco plant are elongated to the stage of initial flowering, first manually wipe off the axillary buds ≥ 2.0 cm long, and then cover all the inflorescences together with the uppermost 3-4 tobacco leaves with a plastic bag sprayed or coated with a bud inhibitor solution Live, and properly fasten the mouth of the bag until the tobacco leaves are harvested.

Embodiment 2

[0023] 1) Use purified water to dilute the systemic or local systemic sprout inhibitor to the concentration specified in the instructions, among which the systemic or local systemic sprout inhibitor is currently recommended by China Tobacco Tobacco Leaf Company;

[0024] 2) Soak cotton balls, sponges, paper, cotton cloth, etc. in the diluted sprout inhibitor solution, fully absorb 10-15ml of the sprout inhibitor solution, and then put the cotton balls, sponge, paper, cotton cloth, etc. in a plastic bag Inside, the selected plastic bag has a thickness of 0.018-0.020mm, a length of 45-50cm, and a width of 25-30cm;

[0025] 3) When the flower buds of the tobacco plant are elongated to the flowering stage, manually wipe off the axillary buds ≥ 2.0 cm long, and then use a plastic bag with a bud inhibitor solution to cover all the inflorescences and the uppermost 3-4 tobacco leaves. Properly fasten the mouth of the bag until the tobacco leaves are harvested.

Embodiment 3

[0027] 1) Use purified water to dilute the systemic or local systemic sprout inhibitor to the concentration specified in the instructions, among which the systemic or local systemic sprout inhibitor is currently recommended by China Tobacco Tobacco Leaf Company;

[0028] 2) Spray part of the sprout inhibitor solution evenly inside the plastic bag, and the other part is adsorbed on the cotton ball, sponge, paper or cotton cloth, and then arrange the cotton ball, sponge, paper or cotton in the plastic bag; the sprout inhibitor solution The total dosage is 10-15ml, the thickness of the selected plastic bag is 0.018-0.020mm, the length is 45-50cm, and the width is 25-30cm;

[0029] 3) When the flower buds of the tobacco plant are extended to the flowering stage, first manually wipe off the axillary buds ≥ 2.0cm long, and use a plastic bag with a bud inhibitor solution to cover all the inflorescences together with the uppermost 3-4 tobacco leaves, and tie them appropriately Tighten...

Abstract

The invention discloses an application method for a tobacco bud inhibitor. The method comprises the following treatment steps: (1) uniformly sprinkling or smearing plastic bags with a systematic or locally-systematic bud inhibitor; or placing bud inhibitor absorbed bud inhibitor carriers into the plastic bags; or using the two methods in a combined manner; and (2) when flower buds of tobacco plants extend to a flowering phase, firstly, manually erasing axillary buds with length not smaller than 2.0cm, then, covering whole inflorescence together with uppermost 3-4 tobacco leaves with the plastic bags treated in the step (1), and properly fastening bag openings until tobacco leaves are completely harvested. A relatively-closed space is formed through applying the systematic or locally-systematic bud inhibitor into the plastic bags and covering the tops of the tobacco plants free of top pruning with the plastic bags, and a high-temperature environment in the space easily causes the atomization of the bud inhibitor, so that effective absorption of the tobacco plants is facilitated, and the bud inhibiting effect is improved; and when in use, the bud inhibitor is free from weather effect, so that the wasting of the bud inhibitor and residual contamination to soil and the tobacco leaves are avoided. At the same time, the effect of improving the quality of upper-part tobacco leaves is obvious.

Description

technical field [0001] The invention relates to a method for applying tobacco systemic or local systemic bud suppressor, and belongs to the field of tobacco cultivation pesticide use. Background technique [0002] As we all know, tobacco is a crop that is harvested from tobacco leaves. In order to improve the yield and quality of tobacco leaves, it is necessary to remove the growth points of tobacco leaves after budding and flowering, regulate apical dominance, inhibit reproductive growth, and promote vegetative growth. Simultaneously in order to avoid growing axillary buds in the leaf axils of the tobacco plant, consuming nutrients, and reducing tobacco leaf yield and quality, the axillary buds must be removed in time after the tobacco leaves are topped. [0003] At present, the methods of removing axillary buds in tobacco production in my country are manual bud removal and chemical bud suppression. Manual bud removal is labor-intensive, labor-intensive, high production cos...
