Abstract
The invention belongs to the field of seed treatment, and in particular discloses a method for treating tobacco seeds, for improving drought resistance and cold hardiness of tobacco seeds. The method for treating the tobacco seeds comprises the following steps: (1) sterilizing the seeds, (2) cleaning and drying the seeds, (3) soaking the seeds by using chemical agents, and (4) rewashing and drying the seeds. By adopting the technical scheme, as the tobacco seeds are subjected to agent soaking treatment, the drought resistance and the cold hardiness are remarkably improved, and the treatment method is simple and feasible and low in cost.
Description
Technical field
The invention belongs to seed treatment field, be specifically related to a kind of processing method of tobacco seed.
Background technology
Tobacco is the warm crop of happiness, poor to low temperature stress tolerance.Chilling injury is the natural calamity often running on tobacco produces, and is one of factor of restriction leaf tobacco production.Meanwhile, tobacco originates from the abundant torrid zone of rainfall, also very high to the requirement of moisture.And part leaf tobacco production district of China is in Hills, not only there is the problem of chilling damage in these areas, and due to reasons such as landform, soil easily occurs water deficit and forms arid infringement, affected the growth of local cigarette seedling.Therefore, improve tobacco seed by the technology such as seed soaking and seedling is cold-resistant, drought-resistant ability has important practical significance.
Summary of the invention
Object of the present invention is just to provide a kind of processing method of tobacco seed, can improve drought resisting, the cold tolerance of tobacco seed.
The processing method of a kind of tobacco seed of the present invention, comprises the following steps (1) seed is carried out disinfection; (2) seed cleans and is dried; (3) adopt chemical reagent to soak seed; (5) seed heavily cleans with dry.
In step 1, adopting mass percent concentration is that 2.1-2.5% liquor natrii hypochloritis carries out disinfection to seed, and disinfecting time is 21-25 min.
In step 2, get seed express developed with distilled water, at 20 ℃, be dried to initial moisture content after blotting the surface of the seed moisture.
In described step 3, chemical reagent adopts in the calcium chloride solution of 7-9 mg/L, dark seed soaking 25 h at 20-30 ℃
In step 5, get seed express developed with distilled water, blot the surface of the seed moisture and be placed at 20 ℃ and be dried to initial moisture content, store stand-by.
By above technical scheme, by the tobacco seed of medicament seed soaking, it can simultaneously cold-resistantly significantly improve with drought-resistant ability, and processing method is simple, with low cost.
Embodiment
A processing method for tobacco seed, comprises the following steps (1) seed is carried out disinfection; (2) seed cleans and is dried; (3) adopt chemical reagent to soak seed; (5) seed heavily cleans with dry.
In step 1, adopting mass percent concentration is that 2.1-2.5% liquor natrii hypochloritis carries out disinfection to seed, and disinfecting time is 21-25 min.
In step 2, get seed express developed with distilled water, at 20 ℃, be dried to initial moisture content after blotting the surface of the seed moisture.
In described step 3, chemical reagent adopts the calcium chloride solution of 7-9 mg/L, and 28h then soaks seed under dark condition at 20-30 ℃.
In step 5, get seed express developed with distilled water, blot the surface of the seed moisture and be placed at 20 ℃ and be dried to initial moisture content, store stand-by.
