Abstract

The invention provides a flue-cured tobacco seedling substrate and a preparation method thereof, and relates to the technical field of flue-cured tobacco seedling growing. The flue-cured tobacco seedling substrate comprises the following components in parts by weight: 0.5-2 parts of pine needles, 1-3 parts of black soil and 0.5-2 parts of vermiculite. The preparation method of the flue-cured tobacco seedling substrate comprises the following steps: smashing the pine needles, mixing the smashed pine needles with the black soil and the vermiculite to obtain a mixed substrate, sterilizing the mixed substrate and regulating the pH value, thereby obtaining the flue-cured tobacco seedling substrate. The flue-cured tobacco seedling substrate and the preparation method thereof provided by the invention have the benefits that as the pine needles, the black soil and the vermiculite form the mixed substrate, nutritional components are full, and the growth of tobacco seedlings is more facilitated; materials used for the seedling substrate are wide in source, cheap and easy to obtain; turfs are not required to be used, so that the damage to an ecological environment is avoided, a seedling effect can achieve that of an existing substrate formula, the production cost is reduced, and the ecological transformation and the utilization of waste and the environmental protection are facilitated. Meanwhile, the preparation method of the flue-cured tobacco seedling substrate, provided by the invention, is simple, convenient to operate and very suitable for large-area popularization and application.

Description

technical field

[0001] The invention relates to the technical field of flue-cured tobacco seedling cultivation, and in particular to a flue-cured tobacco seedling cultivation substrate and a preparation method thereof. Background technique

[0002] Seedling cultivation is the primary link in tobacco production. Cultivating timely, sufficient, orderly and robust tobacco seedlings is the prerequisite for completing the planting plan and the basis for obtaining high-quality, suitable, efficient, and low-cost tobacco leaves. The main component of the existing flue-cured tobacco seedling raising substrate is peat, and the peat content generally accounts for more than 30%. With the promotion and application of substrate seedling raising technology, the amount of seedling raising substrate is increasing year by year, and the amount of peat is also increasing. Peat, also known as "peat" and "peat", is a product of the development of swamps. It cannot be regenerated in a short perio...
