Embodiment 1

[0024] Put 0.6 tons of water into the floating nursery pond to make the water depth 8cm, then add "Jinate" bio-organic liquid fertilizer stock solution into the water by multi-point adding method according to the volume ratio of bio-organic liquid fertilizer: water = 1:40, and stir uniform. The organic matter content of "Jinatai" bio-organic liquid fertilizer is 22%, the total nutrient content is 5%, the humic acid content is 6.7%, and the number of microorganisms is 49×10 8 pcs / g, pH 6.9, N:P 2 o 5 :K 2 O=2:1:2. Next, put the floating plate with safflower Dajinyuan seeds into the floating nursery pond, and then manage it according to the conventional floating seedling cultivation method. During the entire seedling cultivation period, it is necessary to ensure that the surface of the floating pond does not leak light, the bottom film does not leak water, and does not breed. Nitrogenous bryophytes.

Embodiment 2

[0026] Put 1.0 tons of water into the floating nursery pond to make the water depth 10cm, then add "Jinate" bio-organic liquid fertilizer stock solution into the water by multi-point addition method according to the volume ratio of bio-organic liquid fertilizer: water = 1:50, and stir uniform. The nutrient status of "Jinatei" bio-organic liquid fertilizer is the same as in Example 1. Next, put the floating plate with Yunyan 87 seeds into the floating nursery pond, and then manage it according to the conventional floating seedling cultivation method. During the entire seedling cultivation period, it is necessary to ensure that the surface of the floating pond does not leak light, the bottom film does not leak water, and does not breed good nitrogen species within 45 days. Mossy creatures.

Embodiment 3

[0028] Put 1.2 tons of water into the floating nursery pond, so that the water depth is 12cm, and then according to the volume ratio of bio-organic liquid fertilizer: water = 1:60, add "Jinate" bio-organic liquid fertilizer stock solution to the water by multi-point addition method, and stir uniform. The nutrient status of "Jinatei" bio-organic liquid fertilizer is the same as in Example 1. Next, put the floating plate with K326 seeds into the floating nursery pond, and then manage it according to the conventional floating seedling cultivation method. During the entire seedling cultivation period, it is necessary to ensure that the surface of the floating pond does not leak light, the bottom film does not leak water, and no nitrogenous moss grows. creature-like.

Abstract

The invention discloses a floating seedling raising method for cultivating healthy and strong seedlings by using bio-organic liquid fertilizer, which comprises the steps of adding water, fertilizing, placing on trays and managing. First, put water into the floating nursery pond to make the water depth 8~12cm, then add bioorganic liquid fertilizer stock solution into the water according to the volume ratio of bioorganic liquid fertilizer: water = 1:20~80, and then place the floating tray with seeds sown Put it into the floating nursery pond, fertilize and manage according to the conventional floating nursery method. The bio-organic liquid fertilizer selected by the invention has the functions of activating soil nutrients, stimulating crop growth, improving the quality of tobacco seedlings, and increasing dry matter accumulation. The multi-point application method is directly added to the water body, which is convenient to use, saves labor and time. From the perspective of the application effect, the bio-organic liquid fertilizer can completely replace the use of special seedling fertilizer for tobacco at the seedling stage, and is suitable for all main varieties of flue-cured tobacco production. Even in autumn and winter when the temperature is low at the seedling stage, it has obvious effects of promoting the growth of tobacco seedlings, leaf development, and coordinated growth above and below ground.

Description

technical field [0001] The invention belongs to the technical field of tobacco floating seedling cultivation, and in particular relates to a floating seedling cultivation method for cultivating healthy and strong seedlings by using biological organic liquid fertilizer. Background technique [0002] Cultivating robust organic tobacco seedlings is the basis for obtaining high-quality and high-yield organic tobacco leaves. Most of the nutrients required for tobacco seedlings in floating seedling cultivation are supplied by nutrient solution. Quality requirements for the production of ecological high-quality tobacco leaves and organic tobacco leaves. In view of the fact that floating seedling cultivation is the largest and most widely used method of seedling cultivation in recent years, it is necessary to find suitable organic fertilizers to replace chemical fertilizers, and to achieve the goal of reducing the amount of chemical fertilizers by 20% during the "13th Five-Year Plan...
