Example Embodiment

[0020] It can be seen from the above examples that the performance and effect of Example 4 is the best, the performance and effect of Example 3 and Example 5 are good, the performance and effect of Example 2 and Example 6 are average, and the performance and effect of Example 1 and Example 7 are poor.

[0021] For specific implementation, take fresh, pathogen-free, and seedless yellow soil under the surface of the soil, dry it slightly, then mash it, and sieve it with a sieve tray with a sieve opening of 0.5-0.8 cm. With reference to the composition ratio of Example 4, 70% of the commercial carbonized chaff and 30% of the sieved yellow clay were fully mixed according to the volume ratio, and then the bag was ready for use.

[0022] In the practice of flue-cured tobacco production, the substrate of the present invention is loaded into the seedling tray, and the excess substrate on the surface of the tray is scraped off, so that seeding and seedbed follow-up management can be ...

Abstract

The present invention discloses environment friendly tobacco seedling raising medium and its preparation process. The environment friendly tobacco seedling raising medium consists of charred chaff in 50-90 vol% and loess in 10-50 vol%; and its preparation process includes the steps of air drying loess, crushing, sieving, and mixing with charred chaff. The tobacco seedling raising medium has good ventilation, high water maintaining performance, high fertilizer maintaining performance and good heat transferring performance, and can meet the requirement for tobacco seedling to grow.

Description

1. Technical field [0001] The invention relates to a flue-cured tobacco seedling raising substrate and a preparation method thereof, in particular to an environment-friendly flue-cured tobacco seedling raising substrate and a preparation method thereof. 2. Background technology [0002] The existing flue-cured tobacco seedling raising matrix components mainly include carbonized chaff, peat soil, expanded perlite, etc., and the general peat soil accounts for more than 30%. The annual consumption of peat soil in the country reaches 600,000 cubic meters. With the continuous popularization and application of new technologies for substrate seedling cultivation, the amount of substrate used for seedling cultivation has increased, and the amount of peat soil has also increased. Peat soil, also known as peat soil and peat, is a non-metallic mineral resource distributed on the surface of the earth. It is an important natural resource and has been widely used in the practice of crop s...
