Tobacco bare seed seeding device and method

Abstract

The invention provides a tobacco bare seed seeding device, which comprises a rectangular seeding disc with a baffle plate on the periphery, wherein through holes in one-to-one correspondence to tobacco seedling culture disc holes are formed in the disc surface of the seeding disc, wherein the diameter of the through holes is 3 to 5mm; a 40-mesh sieve screen is arranged on each through hole; the edge of the sieve screen is smooth and has no drapes; fixed clamp feet used for clamping the positions of the outer corner edges of the tobacco seedling culture disc are arranged on the four corners ofthe rectangular seeding disc; the horizontal cross section of the fixed clamp feet is of a right angular steel structure; the seeder is also provided with a push plate. A method for seeding by using the seeding device comprises the following steps of firstly filtering a seedling culture substrate by a 40-mesh sieve; then, mixing the filtered dry substrate and seeds according to the proportion of 100:1; then, putting the mixed seed substrate mixture into the seeding disc; pushing the mixture by the push plate to and fro to ensure the falling of 1 to 3 seeds into each seedling culture disc hole.The tobacco bare seed seeding device has the advantages that the uniform seeding of the tobacco bare seed can be realized; the efficiency is high; the waste is avoided; the seed moisture preservationis facilitated; the seed germination rate is improved.

Description

Technical field: [0001] The invention relates to a bare tobacco seed sowing device and method, which are suitable for sowing tobacco seedlings used in fields and laboratories. Background technique: [0002] The sowing in tobacco production is basically all pellet-coated seeds. Due to the existence of the coating, the seed volume is dozens of times that of bare seeds. It is easy to operate during sowing, sows evenly, does not cause waste of seeds, and is convenient for later management. However, in the actual breeding process, many new varieties or lines cannot be coated due to the limited number of seeds, and the tobacco seeds are very small, with a thousand-grain weight of only about 100 mg. Waste and increase post-management workload. In order to better carry out the seedling cultivation of bare seeds, a device and a supporting method that can evenly sow seeds are required in both production and laboratory. [0003] There are many reports on the patents of tobacco bare s...

AI Technical Summary

Problems solved by technology

[0003] There are many reports on the patents of tobacco bare seeds (references [1-9]), but some of these methods are mainly used for a small amount of sowing in the laboratory [1-7], and some are very inefficient [8,9] and are not suitable for multiple Batch operation of the above varieties

In some cases, there will be holes and lack of seedlings, and in some cases, more than 10 seeds will be sown in one seedling hole. growth, so the development of a practical, convenient and fast tobacco naked seed sowing device has attracted the attention of technicians in the industry
