Eggplant Seedlings In The Seedling Tray

Apr. 11, 2022

1. Variety selection

Choose purple eggplant varieties such as purple eggplant and Tanaka which are resistant to low temperature and low light, high yield, fruit type, disease resistance, good commodity, high quality, storage and transportation, and suitable for market demand.

2. Preparation before the broadcast

2.1. Nursery facilities – nursery trays, greenhouses, etc.

According to different seasons, the nursery facilities such as impotence, greenhouse and hotbed are selected. The summer and autumn seedlings should be equipped with marshine insect-proof sunshade facilities to create environmental conditions suitable for seedling growth and development.

2.2. Nutrient soil of seedling propagation tray

Due to the high seeding density, the sowing bed absorbs water and minerals from the bed soil in a large area per unit area. Generally, in marshine method it takes 5 parts of fertile rural soil without pathogens, 4 parts of decomposed farmyard manure, and 1 part of ash. In addition, the root system is dense, and its breathing has strict requirements on oxygen. Therefore, the nutrient soil of the seed bed must have good gas permeability and contain various nutrients required for seedling growth. In addition, 2 kg of diammonium phosphate was added per cubic meter, thoroughly mixed, sieved and crushed, and then made into bed soil.

2.3. Nursery bed

The bed is covered with a small arch shed covering the mulch, which not only maintains moisture but also promotes temperature and promotes emergence.

The method of laying the bed is to first lay a layer of sticky soil, flatten the soil, place 3~5 cm of nutrient soil on top, then pour the water, spread the seeds of the germination evenly on the bed, and then cover 1 cm thick. Nutrient soil. 2.4 Seed treatment. The area of seedlings per acre of field eggplant needs to be 3 square meters.

2.4. Soaking seeds and working in germination trays

Eggplant seeds can be soaked in warm soup or treated with chemicals by adding the seeds to 55 ° C water and stirring until they reach room temperature, or with potassium permanganate 1000 times for 15 to 20 minutes to achieve disinfection. purpose. Eggplant soaking time is 10 to 12 hours. It is required to continuously wash the seeds and remove the mucus to accelerate water absorption and breathing and promote germination. If the temperature is germinated by using 16 hours 30 ° C and 8 hours 20 ° C, the uniformity is obviously improved. After soaking the seeds, remove the seeds from the water and let them dry for 10 to 20 minutes to disperse the water on the surface of the seeds. Wrap them in a clean damp cloth and germination at 27-30 °C. During the germination, it can be washed 1~2 times with warm water of about 30 °C, and continue to germination after drying.

3. Sowing

3.1. Sowing date

In the early spring, the “three-film” cultivation was planted at the end of November; the mulch or open-field cultivation was planted at the beginning of January; and the autumn-post cultivation was planted in the middle and late July.

According to the cultivation season, the seedling raising method and the strong seedling index, the appropriate sowing date is selected.

3.2. Seeding rate 10 grams per square meter seedbed. The cultivated area per 667 square meters is about 50 grams.

3.3. Seeding method When more than 70% of the germination seeds are broken (white), they can be sown, and the summer and autumn seedlings are directly sown with the seeds after disinfection. After sowing, cover the nutrient soil 0.8 cm – 1.0 cm. Pour the bottom water before planting and moisten to 10 cm deep. After the water has been infiltrated, use a layer of nutritious soil to spread a layer, level the bed, and evenly sow the seeds. Each square meter of seedbed reused 2 grams of Luheng No. 1 wettable powder to prevent rickets. In winter and spring, the seedling bed is covered with mulch film, and the dried fine soil is evenly spread on the bed surface. The summer and autumn marshine sowing seedling bed covers the sunshade net or straw, and the bed cover is removed when 70% of the seedlings are topped. After the summer and autumn sowing, the roof of the shed must be covered with shade nets or straw.

4. Seedling management

4.1. Seedling management After planting trays, close the insulation, try to increase the temperature of the seedbed and promote emergence. Eggplant is prone to hatching. The sprayer can be used to spray the shell in the evening, so that the seedlings can be uncapped at night. It is also possible to prevent the capped soil from being unearthed when the seed is arched, evenly spreading a layer of fine soil, and also preventing the air leakage caused by the emergence of the arched soil. During the seedling stage, the daytime temperature should be maintained at 25-28 °C, and the nighttime temperature is 15-18 °C. When you grow 2 true leaves, you can divide the seedlings. After 80% of the emergence, open the mulch to release the wind, reduce the temperature and humidity, and prevent the occurrence of stagnation. One day before seeding, the seedling bed was poured once and permeable.

4.2. Preparation of the seedbed and the preparation of the seedlings. The same as the nutrient soil preparation method of the seedbed. Each acre of field needs to divide the seedbed area by 15 to 20 square meters. In recent years, nutrient mash has been widely applied to the solanaceous seedlings, which can effectively protect the root system and facilitate operation, management and transportation. It is more suitable to use eggplant seedlings with a diameter of 10 cm. The thickness of the marshine seedbed soil is 8-10 cm to ensure the nutrient and air needs of the roots throughout the seedling period. The seedling density is 8 to 10 cm square. Put the nutrient soil into the pot, insert a hole in the center with your fingers, plant the seed into the hole, and then seal the hole to pour water.

5. Strong seedling index winter and spring seedlings.

For 7 to 9 true leaves of eggplant seedlings, the average inter length is about 2 cm, the seedling height is about 20 cm, the stem base is more than 0.5 cm thick, the leaves are dark green, and the eggplant flowers are budded. No pests and diseases. Summer and autumn seedlings, plant height of about 15 cm, 4 leaves and 1 heart, stems about 0.4 cm thick, bred within 25 days.

6. After 3 minutes of management:

The bed will be supported by a small arch shed to increase the temperature, restore root growth as soon as possible, and promote slow seedlings. Generally, growth can be resumed in 5 to 7 days. Subsequently, the seedlings enter the flower bud differentiation stage, and the temperature is required to be appropriately lowered. The daytime temperature is maintained at 25 to 27 ° C to promote flower bud differentiation, and about 15 ° C at night. Treat as appropriate by observing the growth of seedlings and the moisture of the topsoil.

7. Moisture management of seedbed:

To meet the need of water for seedling container, do not over-water or over-control moisture. During the seedlings, the marshine seedlings trays should be properly shaded at noon; after the seedlings are slowed down, the seedlings should be more visible, that is, the film is uncovered during the day and covered at night. If the color of the seedlings is light green and the seedlings are weak, the potassium dihydrogen phosphate and urea can be dissolved in a ratio of 1:1 with warm water, and then 0.5% solution is sprayed with a watering can, and then sprayed again with clean water to prevent burns. When the topsoil is dry and there is mild wilting in the noon seedlings, it should be properly watered in the morning.

8.Fertilization management:

If the bed soil organic fertilizer is sufficient, the seedlings grow normally, generally do not need topdressing. In the case of normal growth of the seedlings, the principle of keeping the face dry and seeing the wetness is the principle. Refining: Early spring seedlings during the day 15-20 ° C, night 10-5 ° C. Summer and autumn seedlings gradually remove the shading net and properly control the moisture.
