Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with specific embodiments, where the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0019] Present embodiment provides a kind of method in flue-cured tobacco floating seedling cultivation, described method comprises the following steps:

[0020] Slag sorting: Screen out slag with a particle size of 1-10mm as the seedling substrate, and use it as slag for flue-cured tobacco floating seedling cultivation. Generally, blast furnace slag mainly contains CaO and SiO 2 、AL 2 o 3 Such oxides, whose total amount is generally above 90%, also contain a small amount of iron and impurities. In order to ensure the emergence of flue-cured tobacco and prevent hole leakage, it is necessary to sort the slag to meet the standards of seedling raising materials. The main method is as follows: first, use a m...

Abstract

The invention relates to the field of floating seedling and discloses a method for floating seedling of cured tobacco. The method adopts slag as a floating seedling matrix. The method adopts the slag as the floating seedling matrix and carries out breeding; not only the slag can replace the conventional floating seedling matrix for floating seedling of the cured tobacco completely, but also the tobacco leaf has harmonious internal ingredients, good quality of aroma, strong combustibility and low content of two sugars, thus the requirements of optimizing the tobacco leaf is achieved. In addition, the slag has low cost, can be obtained locally, does not generate toxicity to soil and tobacco left, can save the energy, protect the environment, improve the utilization ratio of waste, and create good economic, ecological 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...
