Embodiment 1

[0052] (1) Collection and crushing: Most of the unsuitable tobacco leaves contain pathogenic bacteria and insect eggs. Firstly, the unsuitable tobacco leaves are collected in a closed way to reduce the pollution of diseases and insect pests to the tobacco field, and are pulverized by a shredder.

[0053] (2) High-temperature and high-pressure separation treatment: After collecting and crushing unsuitable tobacco leaves, transport them to the filling port of the separation tank with an elevator, and then reach the inside of the separation tank, raise the temperature of the raw materials in the container to 158-164 °C, and the steam pressure reaches 0.5-0.6Mpa, after 1 minute, quickly open the outlet to complete the high temperature sterilization.

[0054] (3) In the fermentation step, the separated unsuitable tobacco leaves, nutrient source substances and auxiliary materials are mixed in a mass ratio of 70:10:20, the water content is adjusted to 50-60%, and 0.5-1‰ of the total a...

Embodiment 2

[0071] (1) Collection and crushing: Most of the unsuitable tobacco leaves contain pathogenic bacteria and insect eggs. Firstly, the unsuitable tobacco leaves are collected in a closed way to reduce the pollution of diseases and insect pests to the tobacco field, and are pulverized by a shredder.

[0072] (2) High temperature and high pressure separation treatment: After collecting and crushing unsuitable tobacco leaves, transport them to the filling port of the separation tank with an elevator, and then reach the inside of the separation tank, raise the temperature of the raw materials in the container to 158°C, and the steam pressure to about 0.6 , After 50 seconds, quickly open the outlet to complete the high temperature sterilization.

[0073] (3) In the fermentation step, the separated unsuitable tobacco leaves, nutrient source substances and auxiliary materials are mixed in a mass ratio of 70: 20: 10, the water content is adjusted to 60%, and 1‰ of the total amount of ferm...

Embodiment 3

[0081] (1) Collection and crushing: Most of the unsuitable tobacco leaves contain pathogenic bacteria and insect eggs. Firstly, the unsuitable tobacco leaves are collected in a closed way to reduce the pollution of diseases and insect pests to the tobacco field, and are pulverized by a shredder.

[0082] (2) High-temperature and high-pressure separation treatment: After collecting and crushing unsuitable tobacco leaves, transport them to the filling port of the separation tank with an elevator, and then reach the inside of the separation tank, raise the temperature of the raw materials in the container to 158°C, and the steam pressure to 0.5Mpa , After 30 seconds, quickly open the discharge port to complete the high temperature sterilization.

[0083] (3) In the fermentation step, the separated unsuitable tobacco leaves, nutrient source substances and auxiliary materials are mixed in a mass ratio of 75:15:10, the water content is adjusted to 500%, and 0.5‰ of the total amount o...

Abstract

The invention discloses a process technology for producing a seedling-growing medium by using tobacco wastes; the process technology comprises the following steps: collecting and crushing the tobacco wastes, separating under high temperature and high pressure, fermenting, fumigating, and disinfecting, so as to obtain a thoroughly decomposed material; uniformly mixing a thoroughly decomposed material, perlite and vermiculite according to a mass ratio of (60-70):(10-30):(10-30), so as to obtain the seedling-growing medium; as turf is replaced by the tobacco waste thoroughly decomposed material, and the perlite and the vermiculite are added according to a certain ratio, the seedling-growing medium provides an excellent nutrition resource, the production cost is reduced, and the deficiency of the non-renewable resource, namely the turf is reduced, the comprehensive utilization of the resource is realized, and the development of the local recycling economy is improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco waste treatment, and in particular relates to a technology for producing seedling raising substrates by using tobacco waste. Background technique [0002] Chemical traditional agriculture is facing problems such as environmental pollution, ecological destruction, and resource depletion. Therefore, it is an important task for the development of modern agriculture to explore a high-quality, efficient and recyclable new agricultural production mode through the development of circular economy, and to form a production mode of "resources→agricultural products→renewable resources→agricultural products". [0003] Tobacco is one of the leading industries in my country's rural economy, and the country's tobacco planting area has reached more than 15 million mu. Tobacco growth requires a large amount of potassium and phosphorus elements, and potassium and phosphorus resources need to be added to the soil e...
