Problems solved by technology

When cultivating tobacco seedlings in existing simple greenhouses or greenhouses, the control of light and temperature in the facility environment is extensive, and it is difficult to make light and temperature meet the growth and development requirements of tobacco seedlings at the same time
Therefore, it is difficult to solve the uneven problem of tobacco seedlings with the existing technologies for growing seedlings using natural light.

Embodiment 1

[0020] The nursery facility adopted in this example is an artificial light-type airtight plant factory; the nursery container is 128 plug trays; the substrate is mixed with vermiculite, perlite, and peat according to 3:1:1, and is made by adding water and fermenting at high temperature; the tobacco varieties are MS Yunyan 85 and MSK326.

[0021] The formula of the nutrient solution of the tobacco seedling raising of the present embodiment is as follows:

[0022] Major elements: calcium nitrate (Ca(NO) 3 ) 2 ·4H 2 O): 410mg / L; magnesium sulfate (MgSO 4 ·7H 2 O): 120mg / L; potassium dihydrogen phosphate (KH 2 PO 4 ): 272mg / L; Ammonium nitrate (NH 4 NO 3 ): 160mg / L; potassium sulfate (K 2 SO 4 ): 74 mg / L.

[0023] Trace elements: manganese sulfate (MnSO 4·H 2 O): 7.2 mg / L; boric acid (H 3 BO 3 ): 5.4 mg / L; ferrous sulfate (FeSO 4 ·7H 2 O): 26.8 mg / L; disodium EDTA (C 10 H 14 N 2 Na 2 O 8 ·2H 2 O): 53.6 mg; copper sulfate (CuSO 4 ·5H 2 O): 0.2 mg / L; zinc su...

Abstract

The invention discloses an artificial light seedling cultivation method of tobacco, belonging to the field of tobacco seedling cultivation. The method can be used for culturing tobacco seedlings within two months by utilizing an artificial light source to adjust and control illumination factors such as illumination intensity, illumination time and the like in the tobacco seedling cultivation environment and combining the environmental elements such as temperature, humidity, concentration of CO2, air velocity and the like as well as proper regulation and control of water and fertilizer. Compared with the traditional tobacco seedling cultivation method, the method improves the tobacco seedling cultivation uniformity, omits the working procedure of cutting seedlings, shortens the production cycle, leads the standard industrial large-scale production to be easily realized, and is beneficial to environmental protection.

Description

technical field [0001] The invention relates to the field of tobacco seedling raising, in particular to an artificial light seedling raising method of tobacco. Background technique [0002] Tobacco industry in my country is a monopoly industry greatly influenced by policies, and implements a management system of unified leadership, vertical management, and monopoly. Tobacco products have been greatly improved in terms of structure, quality and technology, and the harm of cigarette consumption has been greatly reduced. From January to November 2009, China's cigarette manufacturing industry achieved a cumulative industrial sales value of 43.92 million yuan and a total profit of 60.9 billion yuan. Since 1987, the total tax and profit realized by the tobacco industry has ranked first among all industries in the national economy for 14 consecutive years, making great contributions to national construction. It can be said that tobacco production has become a pillar industry in t...
