Spent mushroom substrate tobacco seedling nursery substrate and preparation method thereof

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...
