Embodiment 1

[0023] The tobacco seed germination and strong seedling composition described in this embodiment includes the following components in parts by weight: 80 g of quicklime, 1.5 g of Bacillus subtilis agent (10 billion live spores / g, WP), 80 g of plant ash, and 15 g of ginkgo extract.

[0024] The ginkgo extract is prepared as follows: firstly dry the ginkgo leaves at 60°C until the moisture content is below 13%, then cool to room temperature and pulverize, pass through a 100-200 mesh sieve; mix the pulverized ginkgo leaves with 80wt% The ethanol solution is shaken and extracted at a temperature of 40-45°C for 4-5 hours according to the mass ratio of 1:3.5, and the extract is concentrated in a rotary evaporator to a paste with a water content of less than 10%.

[0025] The tobacco seed germination and seedling strengthening composition is mixed evenly, and 10 g of the obtained mixture is dissolved in clean water to prepare an aqueous solution with a mass concentration of 0.5 wt % t...

Embodiment 2

[0027] The tobacco seed germination and strong seedling composition described in this embodiment includes the following components in parts by weight: 150 g of quicklime, 0.5 g of Bacillus subtilis agent (10 billion live spores / g, WP), 200 g of plant ash, and 5 g of ginkgo extract.

[0028] The ginkgo extract is prepared according to the following method: firstly dry the ginkgo fruit peel at 80°C until the moisture content is below 13%, then cool to room temperature and pulverize, pass through a 100-200 mesh sieve; mix the crushed ginkgo fruit peel with 70wt % ethanol solution according to the mass ratio of 1:5.5, shake and extract at a temperature of 40-45°C for 4-5h, put the extract into a rotary evaporator and concentrate it to a paste with a water content of less than 10%.

[0029] The tobacco seed germination and seedling strengthening composition is mixed evenly, and 10 g of the obtained mixture is dissolved in clean water to prepare an aqueous solution with a mass concen...

Embodiment 3

[0031] The tobacco seed germination and strong seedling composition described in this embodiment includes the following components in parts by weight: 100 g of quicklime, 1 g of Bacillus subtilis agent (10 billion live spores / g, WP), 150 g of plant ash, and 10 g of Ginkgo biloba extract.

[0032] The ginkgo extract is prepared according to the following method: firstly dry the ginkgo fruit peel at 70°C until the moisture content is below 13%, then cool to room temperature and pulverize, pass through a 100-200 mesh sieve, and grind the crushed ginkgo leaves or ginkgo fruit Pericarp and 75wt% ethanol solution according to the mass ratio of 1:4.5, shake and extract at a temperature of 40-45°C for 4-5h, put the extract into a rotary evaporator and concentrate to a paste with a water content below 10%, that is have to.

[0033] The tobacco seed germination and seedling strengthening composition is mixed evenly, and 10 g of the obtained mixture is dissolved in clean water to prepare a...

Abstract

The present invention belongs to the technical field of tobacco cultivation, particularly relates to a tobacco seed germination seedling strengthening agent, and further discloses a preparation method and a use method of the tobacco seed germination seedling strengthening agent. According to the present invention, the formula of the tobacco seed germination seedling strengthening agent is unique, quick lime, Bacillus subtilis, plant ash and a ginkgo extract are adopted as raw materials, and under the premise of no change of the existing seedling culture technical measures, the physiological effects of cold resistance, stress resistance and growth development promoting of seeds can be improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, in particular to a tobacco seed germination and seedling strengthening agent, and further discloses its preparation and use methods. Background technique [0002] Tobacco is a warm-loving crop native to America, and it is also an important economic crop in my country's agricultural production. The optimum growth temperature of tobacco is 25-28°C. The quality of mature tobacco leaves below 16-17°C is relatively poor, and it will stop growing when it is lower than 10-13°C. will die. [0003] Existing tobacco planting mainly adopts the technology of floating seedlings in greenhouses. Floating seedlings is a new method of seedlings. It began in the late 1980s. American tobacco used floating seedlings to raise seedlings. Floating seedling raising technology is to float the foam tray equipped with light seedling raising substrate on the water surface, sow the seeds in the substrate, and t...
