Example Embodiment

[0013] Example 1 of the present invention: edible fungus residue and tobacco seedling nursery substrate, calculated by weight, including 70 parts of edible mushroom residue, 30 parts of mountain sand and tobacco floating nursery nutrient solution; tobacco floating nursery nutrient solution consists of 1× 10 6 Parts of water, 170 parts of urea, 80 parts of phosphorus pentoxide, 200 parts of potassium oxide, 70 parts of superphosphate, 25 parts of magnesium sulfate, 0.5 parts of borax and 0.5 parts of zinc sulfate.

[0014] The preparation method of the edible fungus chaff tobacco seedling substrate is to crush the edible fungus chaff into chaff with a particle size of less than 3mm according to the above weight parts, adjust it to pH 7.5 with quicklime, and add organic material decomposing agent (using the market The conventional organic material decomposing agent sold is sufficient), the weight ratio of the fungus chaff to the decomposing agent is 1000:1, add water and mix until t...

Example Embodiment

[0016] Example 2 of the present invention: edible fungus residue and tobacco seedling nursery substrate, calculated in parts by weight, including 60 parts of edible mushroom residue, 40 parts of mountain sand and tobacco floating nursery nutrient solution; tobacco floating nursery nursery nutrient solution consists of 0.5× 10 6 Parts of water, 200 parts of urea, 100 parts of phosphorus pentoxide, 250 parts of potassium oxide, 80 parts of superphosphate, 35 parts of magnesium sulfate, 0.7 parts of borax and 0.7 parts of zinc sulfate.

[0017] The preparation method is the same as in Example 1.

Abstract

The invention discloses a spent mushroom substrate tobacco seedling nursery substrate and a preparation method thereof. The spent mushroom substrate tobacco seedling nursery substrate comprises the following components in parts by weight: 60-80 parts of mature spent mushroom substrate, 20-40 parts of bonded silica sand and a tobacco floating seedling nursery nutrient solution. According to the preparation method disclosed by the invention, after the mature spent mushroom substrate and the bonded silica sand are mixed, the mixture is jointly used with the special tobacco floating seedling nursery nutrient solution as the tobacco seedling nursery substrate, through the way, a substitute for a grass carbon type tobacco seedling nursery substrate can be provided, tobacco seedlings obtained by nursery are robust and tidy, a root system is advanced, and the effects are better than the existing grass carbon type substrate. The spent substrate is composted and fermented mature bacterial residue, the bonded silica sand is natural weathered bonded silica sand, and the two raw materials have the advantages of extensive sources, convenience in taking the materials, low cost, and simple assembly. Therefore, by popularizing and using the spent mushroom substrate tobacco seedling nursery substrate disclosed by the invention, the seedling nursery cost can be reduced, and the exploitation of grass carbon resource is further avoided for being conductive to environmental protection.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to an edible mushroom chaff tobacco seedling-raising substrate and a preparation method thereof. Background technique [0002] Floating seedling cultivation is the main way of raising flue-cured tobacco seedlings in my country. The main material of floating seedling cultivation substrate is peat, which is popular because of its good physical coordination, stable performance and strong buffer capacity. However, the distribution of peat resources is uneven and non-renewable. The large-scale popularization of peat as a substrate material for floating seedlings will definitely cause the exhaustion of this resource and cause damage to the environment. [0003] my country is a big country in the production of edible fungi. The production scale of edible fungi is large, the distribution is wide, and the amount of edible fungus residues is large and easy to obtain. Using ed...
