Problems solved by technology

Therefore, the tobacco seedlings provided by the above-mentioned patents cannot meet the requirements of organic tobacco leaf production
At the same time, the nutrients needed for the existing floating seedling cultivation mainly come from the application of chemical fertilizers, so the tobacco seedlings provided by the conventional floating seedling cultivation technology do not meet the requirements of organic tobacco leaf production

Embodiment 1

[0020] A special seedling fertilizer for organic smoke, the seedling fertilizer is mixed with borax, bentonite and alcohol waste liquid concentrate with a mass volume percentage of 50% (m / v, unit g / mL) according to the mass volume ratio of 3:50:1000 (m / v, unit g / mL), used as liquid fertilizer.

[0021] Specifically adopt the following method to prepare:

[0022] Concentrate to the alcohol waste liquid of 50% mass volume percentage concentration (m / v, unit g / mL), add borax according to the mass volume ratio of 3g / L, add bentonite at a mass volume ratio of 50g / L, and stir evenly with a mechanical stirring device Then, dispense directly into plastic containers.

[0023] The nutrient content of alcohol waste liquid: total nitrogen 19.1g / L, total phosphorus (in P 2 o 5 Total potassium) 1.50g / L, total potassium (in K 2 O meter) 34.7g / L.

Embodiment 2

[0025] A special seedling fertilizer for organic smoke, the seedling fertilizer is 50g / L natural bentonite added to the concentrated liquid of alcohol waste liquid, and the dry powder obtained through spray drying (abbreviated as alcohol waste liquid dry powder) and borax according to the mass ratio of 1000:6 Mix well and use as solid fertilizer.

[0026] Specifically, the following steps and methods are used for preparation: Preparation of alcohol waste liquid dry powder: the alcohol waste liquid concentrated to 50% concentration, unit g / mL, is added with a mass volume ratio of 50 g / L natural bentonite, spray-dried into powder; The waste liquid dry powder and borax are measured according to a mass ratio of 1000:6, stirred and mixed evenly. When mixing, carry out in a closed container and use mechanical stirring.

[0027] The nutrient content of alcohol waste liquid: total nitrogen 22.8g / L, total phosphorus (in P 2 o 5 Total potassium) 1.50g / L, total potassium (in K 2 O me...

Embodiment 3

[0029] Using the seedling fertilizer prepared in Example 2, measure the nitrogen content, then add water and dilute to different concentrations: the nitrogen content is 100mg / L, the nitrogen content is 150mg / L, the nitrogen content is 180mg / L, and the nitrogen content is 250mg / L.

Abstract

The invention relates to a special seedling raising fertilizer for organic tobacco, and a preparation method and application thereof, belonging to the field of fertilizers. The seedling raising fertilizer is prepared by mixing alcohol slops with borax and bentonite. The seedling raising fertilizer for organic tobacco can satisfy the organic requirements for organic tobacco seedling raising, and the tobacco seedling raised by the seedling raising fertilizer for organic tobacco is not worse than the tobacco seedling raised by the seedling raising fertilizer for inorganic tobacco in the aspects of sound seedling index, leaf chlorophyll content and the like. Meanwhile, the special seedling raising fertilizer for organic tobacco can solve the problem of environmental pollution caused by alcohol slops, and implements cyclic utilization of resources.

Description

technical field [0001] The invention belongs to the technical field of seedling fertilizer for agricultural production, and in particular relates to a special seedling fertilizer for organic tobacco using alcohol fermentation waste liquid as a raw material, a preparation method and application thereof, which meets the requirements for planting organic tobacco and is suitable for floating seedling raising of flue-cured tobacco. Background technique [0002] Yunnan is a large province of flue-cured tobacco production. Both the planting area and tobacco leaf output rank first in the country. The unique light, heat and water and soil conditions have made the growth of high-quality flue-cured tobacco, also known as the main pillar industry of local agriculture. Therefore, how to improve the planting level of flue-cured tobacco is of great significance to the healthy development of Yunnan flue-cured tobacco industry and the stability of regional economy. [0003] In the late 1990s...
