Problems solved by technology

However, the seeds of tobacco are very small. Taking flue-cured tobacco seeds as an example, they are 600 μm to 800 μm in length and 450 μm to 600 μm in width; the thousand-grain weight is 0.07g to 0.09g, and the number of seeds per gram is 11,000 to 14,000. It is difficult to control the number of seedlings sown at the midpoint of the seedling hole, usually 3-5, resulting in a large workload of thinning after emergence and a high amount of seed waste

Embodiment 1

[0021] Take the Duchuan Tobacco Experimental Station in Fangxian County as an example for sowing seedlings in 288-hole seedling trays in the way of floating seedlings in greenhouses. On February 1st, the seedling tray, seedling substrate and tools for seedling cultivation were fumigated and disinfected. On February 20, the bottom of the seedling pond was disinfected with quicklime, and the ground was paved with plastic film to prevent water seepage or extravasation in the seedling pond. On February 25, inject an appropriate amount of water into the nursery pond, the water depth is 10 cm, add 1 Kg of tobacco-specific compound fertilizer (N:P2O5:K2O=10:12:20) per cubic water, and stir with a stick. The seeds were sown on February 27, and the seeds were the naked species of flue-cured tobacco variety Yunyan 87 harvested in August of the previous year.

[0022] First, fill the seedling trays with the seedling substrate prepared in advance, and then place the seedling trays on the ...

Abstract

The invention provides a naked seed water sowing method for tobacco seedling culture. The method comprises the following steps: preparing naked seed suspension liquid by adding 20 to 50ml of water into every 0.1g of tobacco naked seeds, then, sucking the naked seed suspension liquid by using a rubber head dropper, and injecting the naked seed suspension liquid into planting holes of a prepared seed tray. If the method disclosed by the invention is adopted, the rate of emergence can be guaranteed. Compared with a naked seed bunch planting method, the naked seed water sowing method has the advantages that a single-hole multiple-seedling planting hole ratio can be obviously lowered, sowing and thinning labor can be reduced, and the seed use amount is reduced. The method is suitable for tobacco seedling culture ways, such as the paper-pot seedling culture, the nutrition bag seedling culture, the tray seedling culture, the floating seedling culture and the like of tobacco breeding materials.

Description

technical field [0001] The invention belongs to the technical field of tobacco breeding, and in particular relates to a bare seed water sowing method for growing tobacco seedlings. Background technique [0002] Tobacco is the main raw material crop for cigarettes, and it is also an important economic crop in China, and the variety is the basis of flue-cured tobacco production, so the selection of tobacco varieties is very important, and sowing seedlings is an important part of tobacco breeding. Due to the large number of breeding materials, the number of plants that need to be planted for each breeding material is not many, generally between 10-500 plants. Therefore, in the currently popular seedling raising methods of floating tray seedlings, bare seeds are often used for on-demand sowing. However, the seeds of tobacco are very small. Taking flue-cured tobacco seeds as an example, they are 600 μm to 800 μm in length and 450 μm to 600 μm in width; the thousand-grain weight i...
