Embodiment 1
[0016] The purple shale is crushed and sieved, and 10 parts of the purple shale with a particle size of 0.5 mm are sterilized at high temperature to prepare a flue-cured tobacco floating seedling-raising substrate. The raw materials used for preparing the flue-cured tobacco floating seedling raising substrate and the weight ratio are:
[0017] 10 parts purple shale
[0018] Organic fertilizer 0 parts
[0019] Using the flue-cured tobacco floating seedling raising substrate of Example 1 above, an effect evaluation test was carried out. The experiment consisted of 4 treatments with 3 repetitions. The 4 treatments are:
[0020] Treatment 1: 10 parts of river sand (particle size 0.5mm) + 0 parts of decomposed organic fertilizer (oil dry)
[0021] Treatment 2: 10 parts of mountain sand (particle size 0.5mm) + 0 parts of decomposed organic fertilizer (oil dry)
[0022] Treatment 3: 10 parts of purple shale (0.5mm particle size) + 0 parts of decomposed organic fertilizer (oil dr...
Embodiment 2
[0030] Crush and sieve the purple shale, fully mix 65 parts of the purple shale with a particle size of 6 mm and 20 parts of the organic fertilizer (chicken manure) that has been decomposed, and then undergo high-temperature sterilization to prepare the flue-cured tobacco floating seedlings. matrix. The raw materials used for preparing the flue-cured tobacco floating seedling raising substrate and the weight ratio are:
[0031] Purple Shale 65 parts
[0032] 20 servings of organic fertilizer
[0033] Using the flue-cured tobacco floating seedling raising substrate of the above-mentioned embodiment 2, an effect evaluation test was carried out. The experiment consisted of 4 treatments with 3 repetitions. The 4 treatments are:
[0034] Treatment 1: 65 parts of river sand (6mm particle size) + 20 parts of decomposed organic fertilizer (chicken manure)
[0035] Treatment 2: 65 parts of mountain sand (6mm particle size) + 20 parts of decomposed organic fertilizer (chicken manur...
Embodiment 3
[0044] Crush and sieve black shale, mix 30 parts of black shale with a particle size of 3mm and 10 parts of decomposed organic fertilizer (pig manure), and then sterilize and disinfect with chemical agent hydrogen peroxide (hydrogen peroxide) , to prepare the flue-cured tobacco floating seedling culture substrate. The raw materials used for preparing the flue-cured tobacco floating seedling raising substrate and the weight ratio are:
[0045] 30 parts black shale
[0046] 10 servings of organic fertilizer
[0047] Using the flue-cured tobacco floating seedling raising substrate of Example 3 above, an effect evaluation test was carried out. The experiment consisted of 4 treatments with 3 repetitions. The 4 treatments are:
[0048] Treatment 1: 30 parts of river sand (3mm particle size) + 10 parts of decomposed organic fertilizer (pig manure)
[0049] Treatment 2: 30 parts of mountain sand (3mm particle size) + 10 parts of decomposed organic fertilizer (pig manure)
