Embodiment 1

[0012] Example 1: According to the volume, take 4 parts of purple sand shale and 2 parts of perlite crushed to a diameter of 2mm, then add 0.5 part of powdered bio-organic fertilizer, add water and mix well to form a flue-cured tobacco seedling substrate with a moisture content of 15% .

Embodiment 2

[0013] Example 2: Take 4 parts of deep clay soil and 2 parts of perlite crushed into 2mm diameter by volume, and add 0.5 part of powdered bio-organic fertilizer, add water and mix thoroughly to form a flue-cured tobacco seedling raising substrate with a moisture content of 15%.

Embodiment 3

[0014] Example 3: According to the volume, crushed into 8 parts of purple sand shale with a diameter of 2mm and 4 parts of perlite, then add 1 part of powdered brown coal powder and 0.5 part of powdered bio-organic fertilizer, add water and mix well to form a moisture content 15% flue-cured tobacco seedling substrate.

Abstract

The invention provides an afloat tobacco seedling raising substrate, belongs to the technical field of organic fertilizer application, and in particular relates to a substrate suitable for afloat tobacco seedling raising. The afloat tobacco seedling raising substrate is characterized by consisting of broken deep soil grains, broken perlite grains and powdered bio-organic fertilizer at a volume ratio of 3-5:2:0.5-1 and 14-18% of water. Raw materials of the new afloat tobacco seedling raising substrate are not natural resources clearly forbidden by the government, which does not bring negative effect on environment. And the substrate is rich in nutrient substances and does not carry germ, thus benefiting growth and development of seedlings, and causing a higher survival rate and healthy seedlings.

Description

Technical field [0001] The invention belongs to the technical field of organic fertilizer application, in particular to a substrate suitable for floating seedlings of flue-cured tobacco. Background technique [0002] Floating seedlings is a commonly used method for growing seedlings in flue-cured tobacco production. The existing seedling substrates are all produced by professional manufacturers, and the raw materials are mainly peat, perlite, and vermiculite. Among them, because peat is a precious natural resource, it is considered to be the lungs of the earth. If it is over-exploited, it will cause serious damage to the natural environment. The country has currently restricted its exploitation. Therefore, the replacement of floating seedling substrate for flue-cured tobacco needs to be solved urgently. The invention patent No. 200510048691.3 discloses a floating seedling raising method using sand as a substrate material. This method overcomes the shortcomings of conventional flu...
