Problems solved by technology

The three major thermal power plants produce about 4.5 million tons of waste fly ash every year, which is mainly stored in ash yards, which not only takes up a lot of land, wastes water resources, increases pollution, but also increases the cost of landfilling coal ash in power plants

Embodiment 1

[0027] The flue-cured tobacco floating seedling raising method provided by the present embodiment comprises the following steps:

[0028] screening fly ash;

[0029] Use expanded perlite accounting for 5% to 15% of the total volume to adjust the permeability and buffering properties of fly ash;

[0030] Conduct pH test on fly ash, if the pH value of fly ash is greater than 8.5, use acidic fertilizer or acidic substance to adjust, adjust the pH value of slag to 6~7.5, if the pH value of fly ash is less than 8.5, do not It needs to be adjusted, and in the present embodiment, the superphosphate solution is preferably used for pH adjustment.

[0031] Moisture balance of fly ash: adjust the pH value of fly ash and the adjustment of permeability and buffering property at the same time, use clean water for water balance, and the moisture content of fly ash is more suitable for 60-70%;

[0032] Sowing in a tray: spread the fly ash on the tray, press out a 2-3mm seed hole, and sow th...

Embodiment 2

[0037] The difference between the flue-cured tobacco floating seedling raising method as described in Example 1 is that in this example, 20% to 30% of the total volume of high-temperature decomposed orange stalk farmyard manure is used to adjust the permeability and buffering properties of fly ash.

Embodiment 3

[0039] The difference between the flue-cured tobacco floating seedling raising method as described in Example 1 is that in this example, vermiculite accounting for 5% to 15% of the total volume is used to adjust the permeability and buffering properties of fly ash.

Abstract

The invention relates to the float seedling field, and discloses a float seedling method of a cured tobacco. In the method, pulverized fuel ash is used as a float seedling substrate. The invention cultures the cured tobacco by using the pulverized fuel ash as the float seedling substrate, and the pulverized fuel ash can completely substitute the conventional float seedling substrate to carry out the float seedling on the cured tobacco, can be obtained from local resources, has the advantages of low cost, no poison to soil and tobacco, energy saving and environmental friendliness, and raises the salvage value, thereby creating favorable economic benefits, ecological effects and social benefits.

Description

technical field [0001] The invention relates to the field of floating seedling cultivation, in particular to floating seedling cultivation of flue-cured tobacco. Background technique [0002] Floating seedling cultivation is the main seedling raising method for flue-cured tobacco and vegetable production, which has the advantages of stable performance, convenient operation, convenient centralized management, and easy mastery of technology. This method of raising seedlings has made a huge contribution to the production of high-quality tobacco and the improvement of tobacco leaf production. Flue-cured tobacco floating seedlings need to use a substrate, and the key to the substrate is how to use a material with stable physical and chemical properties, a wide range of sources, low price, no pollution to the environment, and convenient for large-scale commercial production. In my country, the main component of the floating seedling substrate is peat (peat). Peat is popular becau...
