Embodiment 1

[0044] The tobacco seedling substrate is composed of the following materials: decomposed corn cob hydrolyzed residue, sand, horse manure, vermiculite, and papermaking black liquor alkali lignin fertilizer. The mass ratio of the decomposed corncob hydrolyzed residue, horse manure, vermiculite, and papermaking black liquor soda lignin fertilizer in the substrate is 3.5:1.5:1.5:1.2:0.8, and the raw materials are mixed uniformly.

[0045] The preparation method of the tobacco seedling raising substrate is as follows:

[0046] (1) Add a starter equivalent to 2% of the total weight of the raw materials into the corncob hydrolysis residue and mix well, and then ferment for about 15 days in a closed fermentor to obtain the decomposed corncob hydrolysis residue.

[0047] (2) Papermaking black liquor, add dropwise 10% hydrochloric acid solution to pH=2 under stirring conditions; after centrifugal separation, pour out the supernatant, and dry the remaining solids to obtain papermaking black liq...

Embodiment 2

[0066] The tobacco seedling substrate is composed of the following materials: decomposed corn cob hydrolyzed residue, sand, chicken manure, vermiculite, papermaking black liquor alkali lignin fertilizer. The mass ratio of the decomposed corncob hydrolyzed residue, horse manure, vermiculite, and papermaking black liquor soda lignin fertilizer in the matrix is ​​3:1:1.5:1:0.5, and the raw materials are mixed uniformly.

[0067] The preparation method of the tobacco seedling raising substrate is as follows:

[0068] (1) Add a starter equivalent to 2% of the total weight of the raw materials into the corncob hydrolysis residue and mix well, and then ferment for about 15 days in a closed fermentor to obtain the decomposed corncob hydrolysis residue.

[0069] (2) Papermaking black liquor, add dropwise 10% hydrochloric acid solution to pH=2 under stirring conditions; after centrifugal separation, pour out the supernatant, and dry the remaining solids to obtain papermaking black liquor alkal...

Embodiment 3

[0088] The tobacco seedling substrate is composed of the following materials: decomposed corn cob hydrolyzed residue, sand, horse manure, vermiculite, and papermaking black liquor alkali lignin fertilizer. The mass ratio of the decomposed corncob hydrolyzed residue, horse manure, vermiculite, and papermaking black liquor soda lignin fertilizer in the substrate is 4:2:2:1.5:1, and the raw materials are mixed uniformly.

[0089] The preparation method of the tobacco seedling raising substrate is as follows:

[0090] (1) Add a starter equivalent to 2% of the total weight of the raw materials into the corncob hydrolysis residue and mix well, and then ferment for about 15 days in a closed fermentor to obtain the decomposed corncob hydrolysis residue.

[0091] (2) Papermaking black liquor, add dropwise 10% hydrochloric acid solution to pH=2 under stirring conditions; after centrifugal separation, pour out the supernatant, and dry the remaining solids to obtain papermaking black liquor alka...

Abstract

The invention discloses a tobacco seedling cultivating base material and a preparation method thereof. The tobacco seedling cultivating base material is prepared by the following components including, by weight, 3-4 parts of mature corncob hydrolysis residues, 1-2 parts of sandy soil, 1.5-2 parts of animal waste, 1-1.5 parts of vermiculite, 0.5-1 part of papermaking black liquor alkali lignin fertilizer. The tobacco seedling cultivating base material is loose and porous, good in breathability, good in the water and fertilizer conservation, balance, scientific and reasonable in nutrient supply and capable of meeting the balance requirement on nutrient elements of tobacco seedlings in the whole growth period, improving the seedling growing quality effectively, and improving the survival rate and lowering the rate of catching diseases.

Description

Technical field [0001] The invention belongs to the technical field of floating seedling raising substrates, and specifically relates to a tobacco seedling raising substrate and a preparation method thereof. Background technique [0002] Seedling raising is an important technical link in tobacco production. The quality of seedlings directly affects the growth and development, yield and quality of tobacco. Therefore, cultivating strong seedlings is the first step to produce high-quality tobacco leaves. The ideal tobacco seedlings should be disease-free, with well-developed root systems, high orderliness, strong resistance to adversity, quick return to seedlings after transplanting, and high survival rate. The substrate is the most important in floating seedlings, and it is the key factor that determines the growth environment of tobacco seedling roots. At present, the tobacco floating seedlings matrix is ​​mainly made of peat, perlite, vermiculite and other components, but becaus...
