Problems solved by technology

The tobacco-specific floating seedling-raising substrate of the present invention uses tobacco stalks instead of a large amount of peat, which not only solves the problem that the traditional seedling-raising substrate is prepared with a large amount of peat that will destroy ecological resources, but also can largely reduce the damage caused by the natural decay of tobacco stalks to the soil ecological environment. destroy

Embodiment 1

[0032] A novel floating seedling-raising substrate dedicated to tobacco, expressed in weight percentage, said floating seedling-raising substrate is composed of 37% decomposed tobacco stalks, 33% carbonized tobacco stalks, 17% decomposed rice straws and 13% peat.

[0033] The raw material decomposed tobacco stalks: the moisture content is 35%, 7% of the decomposed tobacco stalks have a particle diameter of <1mm, 19% have a particle diameter of 1-2mm, 62% have a particle diameter of 2-5mm, and 62% have a particle diameter of 2-5mm. 12% are 5-8mm.

[0034] The raw material carbonized tobacco stalks: 2% of the carbonized tobacco stalks have a particle diameter of <1mm, 21% have a particle diameter of 1-2mm, 67% have a particle diameter of 2-5mm, and 67% have a particle diameter of 5-8mm. 10%.

[0035] The decomposing method of raw material decomposed tobacco stalks: firstly crush the harvested fresh tobacco stalks, the particle size of the crushed tobacco stalks is 2-5cm, then d...

Embodiment 2

[0039] Embodiment 2: basically the same as Embodiment 1, the difference is:

[0040] A novel tobacco-specific floating seedling-raising substrate, expressed in weight percentage, said floating seedling-raising substrate is composed of 30% decomposed tobacco stalks, 35% carbonized tobacco stalks, 20% decomposed rice straws and 15% peat.

[0041] The raw material decomposed tobacco stalks: the moisture content is 36%, 5% of the decomposed tobacco stalks have a particle diameter of <1mm, 15% have a particle diameter of 1-2mm, 70% have a particle diameter of 2-5mm, and 70% have a particle diameter of 2-5mm. 5 ~ 8mm accounted for 10%.

[0042] The raw material carbonized tobacco stalks: 5% of the carbonized tobacco stalks have a particle diameter of <1mm, 15% have a particle diameter of 1-2mm, 68% have a particle diameter of 2-5mm, and 68% have a particle diameter of 5-8mm. 12%.

[0043] The decomposing method of raw material decomposed tobacco stalks differs from that of Example...

Embodiment 3

[0047] Embodiment 3: basically the same as Embodiment 1, the difference is:

[0048] A novel floating seedling-raising substrate dedicated to tobacco, expressed in weight percentage, said floating seedling-raising substrate is composed of 40% decomposed tobacco stalks, 30% carbonized tobacco stalks, 20% decomposed rice straws and 10% peat.

[0049] The raw material decomposed tobacco stalks: the moisture content is 37%, 10% of the decomposed tobacco stalks have a particle diameter of <1mm, 15% have a particle diameter of 1-2mm, 60% have a particle diameter of 2-5mm, and 60% have a particle diameter of 2-5mm. 5 ~ 8mm accounted for 15%.

[0050] The raw material carbonized tobacco stalks: 25% of the carbonized tobacco stalks have a particle diameter of 1-2mm, 65% have a particle diameter of 2-5mm, and 10% have a particle diameter of 5-8mm.

[0051] The difference between the decomposing method of raw material decomposed tobacco stalks and Example 1 is that the addition of urea ...

Abstract

The invention discloses a novel floating seedling substrate special for tobacco and a preparation method thereof. The floating seedling substrate consists of the following raw materials in percentage by weight: 30 to 40 percent of decomposed tobacco straw, 25 to 35 percent of carbonized tobacco straw, 15 to 20 percent of decomposed rice straw and 10 to 15 percent of grass carbon. The preparation method comprises the following steps of: preparing various raw materials according to the mixture ratio of the novel floating seedling substrate special for the tobacco; leaching the carbonized tobacco straw by water with a pH value of between 5.5 and 6.5 for 5 to 10 minutes; drying the leached carbonized tobacco straw until no open water flows outwards; uniformly mixing and stirring the various raw materials; sterilizing the mixture at the high temperature of 250 DEG C for 10 to 15 minutes; and adjusting water content until the water content meet the requirement of a product so as to obtain the product of the invention. The grass carbon in a conventional seedling substrate mixture ratio is replaced by a large amount of tobacco straw, so the problem of ecological environmental damage due to the use of a large amount of non-renewable resources and the problem of soil ecological environmental damage due to natural decay of the large amount of tobacco straw are solved, the large amount of tobacco straw are recycled and waste materials are recycled. Therefore, the novel floating seedling substrate special for the tobacco has remarkable economic and social benefits.

Description

1. Technical field: [0001] The invention relates to a tobacco seedling-raising substrate, in particular to a novel tobacco-specific floating seedling-raising substrate and a preparation method thereof. 2. Background technology: [0002] Tobacco floating seedlings are live broadcasting tobacco seeds in a seedling tray filled with a substrate, and the seedling tray floats in a pool filled with nutrient solution. The nutrients and water required for the growth of tobacco seedlings are evenly supplied to the tobacco seedlings through the capillary action of the substrate. Substrate is the core technology of floating seedling cultivation. The main function of substrate is to fix the root system of tobacco seedlings, support the growth of tobacco seedlings, absorb nutrient solution, and provide suitable water and oxygen for tobacco growth. [0003] Tobacco floating seedling cultivation is an advanced seedling raising technology popularized at present, and it is the main technical ...
