As agriculture gains widespread attention, there is a high expectation for its production and development. With the advancement of society, there is also increased concern for the relevant equipment used in agriculture. One area of particular interest is the use of seedling trays. The use of seedling trays is believed to be well-known, as they protect the growth of seedlings and are highly valued by many. Nevertheless, it is still important to inform everyone that there are practical techniques to master for strong seedling growth, ensuring the healthy development of the seedlings.

One: Prepare nutrient soil. Collect soil from plots that were planted with scallions, garlic, or have not grown solanaceous vegetables in the past few years. Mix the soil with garden soil, decomposed horse manure, and stable manure in a 1:1:1 ratio. Then, add phosphoric acid calcium that is equivalent to 0.1~0.2% of the nutrient soil weight and fill it into the seedling beds, compacting and leveling it.

Seed Disinfection: Soak seeds in warm water at 55℃ or immerse in a 10% sodium tripolyphosphate solution for 20-30 minutes. After removing, rinse thoroughly with clean water and then proceed with germination and sowing.

Three, Seed Treatment. By using a magnetized seed treatment device, seeds can be magnetized. Alternatively, multi-functional ozone water can be used for seed treatment, or the "863 Bio-Growth Enhancer" can be employed to nano-process the seeds. After processing the seeds with any one of the above three methods or all three simultaneously, the enzyme activity within the seeds is activated and enhanced, significantly improving the disease resistance of the seeds. Generally, this can lead to earlier germination by 3 to 4 days and faster, stronger seedling growth.

Four, Timely Sowing: Calculate the appropriate sowing period based on the planting date. Before sowing, water the seedbed thoroughly, then proceed with sowing, covering the seeds, and sealing the ground film.

Temperature Management: Generally, for seedling of solanaceous vegetables, maintain temperatures between 25-30℃ before germination; post-germination, maintain 20-22℃ during the day and 15-16℃ at night; before transplanting, maintain 25-28℃; after transplanting, maintain 20-25℃ during the day and 15-18℃ at night. Conduct a low-temperature acclimatization 7-10 days before planting to enhance the survival rate of the transplanted solanaceous vegetables.

Six. Lighting Management. Vegetable crops such as eggplants and tomatoes thrive in strong light, growing robustly under such conditions, while they tend to become leggy and prone to diseases in low light. Specific lighting management measures include:

Ensure glass or plastic film remains clean to minimize water and dust accumulation, enhancing light transmission rates.

To maximize sunlight hours, uncover and cover the tarp early in the morning and late in the evening while ensuring the temperature remains stable.

Install reflective screens to enhance lighting intensity and coverage area.

④ Even on cloudy days, we uncover the shade cloths.

Seven: Moisture Management. Ensure thorough bottom watering before sowing; avoid immediate watering after sowing; water once during seedling emergence; water from one end, do not back and forth repeatedly. After each watering, sprinkle some dry soil or草木灰 when the leaves are free of water stains to retain moisture, prevent soil compaction and temperature drop. Avoid watering on overcast or snowy days.

Before planting, harden off seedlings. Five to seven days prior to planting, conduct night-time low-temperature training. If the seedlings are too tender, to avoid frost damage, they can first be trained at a higher temperature (7-10℃) for several days, and then further hardening off can be carried out. The suitable temperatures for hardening off solanaceous vegetables are: tomatoes at 3-5℃; eggplants and peppers at 8-11℃, with a training period of 3-5 days. After low-temperature training, solanaceous vegetables can significantly improve their adaptability, withstand general frost, and recover quickly after planting, with early growth. Additionally, methods such as increasing seedling spacing and removing the film to expose the seedlings to sunlight can be used to promote strong seedlings, enhance their resistance to adversity, and increase the survival rate of the plants.

The techniques for seedling cultivation and strengthening introduced above are hoped to help you recognize more, all for the growth of crops. If you have any other questions, please feel free to call for further consultation!
