Problems solved by technology

However, if the organic water-soluble fertilizer is applied inappropriately, it will not only have poor absorption of its nutrient elements, but also have limited improvement in the quality of tobacco seedlings, and will also cause increased production costs and waste.

Embodiment 1

[0025] Put 1.0 tons of water into the floating nursery pond to make the water depth 10cm, then add "Holiden" fish protein organic water-soluble fertilizer stock solution into the water according to the volume ratio of 1:2000, and stir evenly. "Haoliden" fish protein organic water-soluble fertilizer has a pH value of 4.26, an organic matter content of 44.94%, a total nitrogen content of 4.90%, a total phosphorus content of 0.33%, a total potassium content of 1.66%, and a total free amino acid content of 4.09%. The total copper content is 2.66mg / kg, the total zinc content is 15.16mg / kg, the total iron content is 419.98mg / kg, the total manganese content is 18.21mg / kg, the total molybdenum content is 0.11mg / kg, and the total boron content is 9.51 mg / kg. Next, put the seedling tray sown with the Dajinyuan safflower seeds into the floating seedling pond. The length and width of the seedling tray are 66.5cm×34cm. After that, it can be topdressed and managed according to the conventi...

Embodiment 2

[0027] Put 0.6 tons of water into the floating nursery pond to make the water depth 8cm, then add "Holiden" fish protein organic water-soluble fertilizer stock solution into the water according to the volume ratio of 1:1000, and stir evenly. The active ingredient of "Holiden" fish protein organic water-soluble fertilizer is the same as that in Example 1. Next, put the seedling tray sown with Yunyan 87 seeds into the floating seedling pond, and the length and width of the seedling tray are the same as in Example 1. After that, it can be topdressed and managed according to the conventional floating seedling raising method. Topdressing scheme is with embodiment 1.

Embodiment 3

[0029] Put 1.2 tons of water into the floating nursery pond to make the water depth 12cm, then add "Holiden" fish protein organic water-soluble fertilizer stock solution into the water according to the volume ratio of 1:5000, and stir evenly. The active ingredient of "Holiden" fish protein organic water-soluble fertilizer is the same as that in Example 1. Next, the seedling-raising tray that is sown with K326 seeds is put into the floating seedling-raising pool, and the length and width of the seedling-raising tray are the same as in Example 1. After that, it can be topdressed and managed according to the conventional floating seedling raising method. Topdressing scheme is with embodiment 1.

Abstract

The invention discloses a floating seedling culturing method for improving tobacco-seedling stress resistance and disease resistance through fish-protein organic water-soluble fertilizer. The method includes the steps of water adding, fertilizer applying, disc putting and managing, wherein water is drained into a floating seedling culturing pool, and the water depth is 8 cm to 12 cm; then according to the volume ratio of 1:(1,000-6,000), raw liquid of the fish-protein organic water-soluble fertilizer is added into water; floating discs with sowed seeds are put into the floating seedling culturing pool, and top dressing and managing can be carried out with a conventional floating seedling culturing method. The fish-protein organic water-soluble fertilizer selected in the floating seedling culturing method has rich nutrient substances such as protein, peptide, amino acid, vitamins, a large quantity of microelements, enzymes and natural active substances, and is directly added into water with the multi-point applying method, labor and time are saved, operation is easy, root development of tobacco seedlings can be more effectively promoted, stems are thick and strong, and over-ground parts and underground parts grow in a balanced mode; as the tobacco seedlings have the certain cold resisting capacity and disease resisting capacity, the fish-protein organic water-soluble fertilizer is suitable for all main cultivated varieties of flue-cured tobacco production, particularly is suitable for application and popularization of planting areas with the low temperature in the seedling stage or planting areas with serious cold spell in later spring in the seedling stage.

Description

technical field [0001] The invention belongs to the technical field of floating seedling cultivation of tobacco, and in particular relates to a method of floating seedling cultivation which uses fish protein organic water-soluble fertilizer to improve stress and disease resistance of tobacco seedlings. Background technique [0002] As the saying goes: half of the seedlings are harvested. Most of the nutrients required by tobacco seedlings in floating seedling cultivation are supplied by the nutrient solution, and the root system of tobacco seedlings absorbs nutrients and water from the nutrient solution through the substrate. Therefore, the composition and proportion of fertilizers applied in the nutrient solution for floating seedling cultivation are very important for promoting the healthy growth of tobacco seedlings. , It is of great significance to improve the stress and disease resistance of tobacco seedlings and the survival rate of transplanting. (1) As more and mo...
