Problems solved by technology

However, since plant growth is the joint effect of different light qualities, the light qualities used by the above researchers are relatively single and incomplete.
For practical application, there are still problems: 1. There is no specific spec

Embodiment 1

[0021] (1) Peat soil and vermiculite with a particle size of 0-10 mm are evenly mixed with a mass ratio of 1: 1 to form a matrix, put in a sowing tray, determine the humidity of the matrix to 90% according to the kind of tobacco seeds used, and then For sowing, 2 to 3 seeds are randomly sown in each hole, the surface is covered with a film, and the ambient temperature is controlled at 24-26°C. After germination, the film is lifted in time to obtain seedlings;

[0022] (2) Seedling cultivation: transplant the above-mentioned seedlings to the seedling cultivation equipment, and cultivate them for 10 days under the conditions of 24-26° C. and air humidity of 60-70%. 2 *s, photoperiod 12h / d; Hoagland nutrient solution is poured regularly, wherein, the spectral energy distribution in the above-mentioned photoperiod is as follows: the number of photons with a wavelength of 380-399nm accounts for 0.1%, and the number of photons with a wavelength of 400-499nm The proportion of light q...

Abstract

The invention discloses an artificial luminous environment cultivation method of tobacco. The method comprises the steps of (1) uniformly mixing peat soil and vermiculite to form a matrix, installing the matrix into a sowing disc, determining humidity of the matrix according to the variety of tobacco seeds, then sowing the tobacco seeds, uncovering a film timely after germination, and obtaining seedlings; (2) seedling growing: transplanting the seedlings to a seedling growing device, and cultivating the seedlings for 15-20 days at the temperature of 23-28 DEG C and under the air humidity of 60-70%; and (3) cultivation: transplanting the plants obtained in the step (2) to a cultivation region, and cultivating the plants at the temperature of 23-28 DEG C and under the air humidity of 60-70% until harvesting the tobacco. The artificially cultivated tobacco is prevented from being influenced by adverse climatic conditions, and annual continuous production is achieved. Leaf surfaces of the planted tobacco plants are light green, roots are developed, stems are flexible, strong and not easy to break, and yield is obviously increased compared with a traditional fluorescent lamp method.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating tobacco in an artificial light environment. Background technique [0002] my country is the world's largest tobacco-producing country, and the tobacco industry plays an important role in the national economy. The optimum temperature for tobacco growth in my country is 25°C to 28°C, and the sunshine hours are required to be more than 600 hours. At present, tobacco planting is seriously affected by the external environment. Low light intensity, insufficient light hours, and frequent frosts in the seedling and growth stages lead to thin tobacco plants and poor stress resistance, which greatly affects the yield and quality of tobacco leaves. Especially in the seedling raising period, the lack of light will cause the seedlings to grow slowly, the seedling raising period will become longer, the cost will increase, and the poor quality of t...
