Embodiment 1

[0038] Three batches of naked tobacco species of different varieties were taken, numbered respectively as Yunyan 85-0164, Yunyan 97-0228, and MSK326-0402.

[0039] 1.1 Take the commercially available tobacco substrate, pour it into a mesh sieve with a pore size of 5 mm, shake and sieve it, remove impurities or stones with excessive particle size, and crush the substrate bonded into blocks for later use. Prepare 2mg / L butenolide mother liquor, then get mother liquor and be mixed with 0.15μg / L, 1.5μg / L, 15μg / L, 150μg / L butenolide solution respectively.

[0040] 1.2 Comparative example: Take 100g of sieved substrate, spread it in a 570ml germination box, add 80ml of water, mix evenly; spread the substrate, and evenly sow 100 grains of the above-mentioned 3 batches of tobacco bare seeds in each box, Do 3 repetitions, place at 25°C for seedling emergence test, spray water during the period to keep the substrate moist, and count the seed emergence rate in 5 to 7 days. The statistica...

Embodiment 2

[0048] The difference between the present embodiment 2 and embodiment 1 is that the tobacco seeds sown are 3 batches of seeds of the same variety with different storage years (different vigor): 2001-0064, 2002-0138, 2014-2882. After sowing, the seeds were first placed in a low temperature treatment at 5°C for 4 days, then transferred to 25°C for emergence, and the seed emergence rate was counted on the 7th day after transfer to 25°C, which was used as the result of the determination of seed cold resistance activity.

[0049]It can be seen from Table 2 that when the substrate mixed with butenolide is used for seedling cultivation, after the seeds encounter low temperature stress, the normal emergence temperature is restored, and the seeds in the substrate containing 0.15-15 μg / L butenolide solution The emergence rate is higher than that of the water-containing medium. For example, the emergence rate of the seeds of 2002-0138 in the 0.15-15 μg / L solution-treated medium increased ...

Abstract

The invention discloses a matrix treatment method which comprises the following steps: (1) taking a commercially available tobacco matrix as a to-be-treated matrix, pouring the to-be-treated matrix into a mesh screen, and screening to remove impurities or stones with overlarge particle sizes; and (2) preparing a butenolide solution, adding the solution into the screened tobacco matrix to be treated in the step (1), stirring, and fully mixing the matrix and the solution to obtain the treated matrix. The invention further discloses a tobacco seed seedling raising method using the substrate. The low-temperature stress resistance of the tobacco seeds can be enhanced, the seedling rate of the tobacco seeds encountering low temperature is increased, the tobacco seedling quality is improved, the economic loss in the seed seedling raising process caused by low-temperature stress is reduced, and the effect of promoting farmers to increase income and yield is achieved; the cost is low, the method is simple and convenient to implement, the effect is remarkable, and the good application potential is achieved.

Description

technical field [0001] The invention relates to the technical field of tobacco seedling cultivation, more specifically, to a substrate treatment method and a method for growing tobacco seedlings using the substrate. Background technique [0002] Tobacco seeds are the source of the tobacco industry, and it is the basis for high-quality and stable production of tobacco leaves. When tobacco seeds are used in domestic tobacco areas, floating seedlings are mostly used. The operation of floating seedling cultivation is generally to sow the tobacco seeds into the floating tray filled with the substrate. The substrate, as a water storage and nutrient supply material, plays an important role in the process of seed emergence. The survey of tobacco areas found that many seedling problems in the seedling raising process are caused by substrate problems, which are easily overlooked. And in the tobacco seed seedling raising process, due to improper method, cause the problem that the qua...
