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. Creatures.

Abstract

The invention discloses a floating seedling culturing method for culturing healthy strong seedlings through biological organic liquid 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 the biological organic liquid fertilizer to water of 1:(20-80), raw liquid of the biological organic liquid fertilizer is added into water; floating discs with sowed seeds are put into the floating seedling culturing pool, and fertilizer applying and managing can be carried out with a conventional floating seedling culturing method. The biological organic liquid fertilizer selected in the floating seedling culturing method has the effects of activating soil nutrients, exciting crop growth, improving the tobacco seedling quality and increasing dry matter accumulation, and is directly added into water with the multi-point applying method, using is convenient, and labor and time are saved; in the applying effect aspect, seedling culturing fertilizer special for tobacco can be completely replaced with the biological organic liquid fertilizer in the seedling stage, and the biological organic liquid fertilizer is suitable for all main cultivated varieties of flue-cured tobacco production, and also has the effects of obviously promoting tobacco seedling growth, leaf development and coordinate growth ground and underground in summer and winter with the low air temperature in the seedling stage.

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 Pl...
