Detailed guide to sowing and raising seedlings in seedling trays

Autumn is a very suitable season for sowing, especially if the temperature is kept between 15 and 25 degrees. The seeds of most plants can germinate normally. If the temperature is too high or too low, the germination rate of the seeds will be affected.

Before sowing plants, it is recommended to buy a container for sowing. You can use a seedling tray, preferably a high-foot plug tray, which can make the plant's seedling root system grow more vigorously. Then transplant it into the potting soil and then transplant it. The success rate will be higher and recovery will be faster when you get to the ground.

The weather in autumn is relatively dry, so it is best to choose some seedling trays with lids to keep warm and moisturizing. Of course, you can also make some small seedling pots by yourself, or even use disposable cups to grow seedlings in a variety of ways (you need to cut a few more holes at the bottom of the container) ), you can cover the seedling pot with some plastic film, wait for the seedlings to grow, and then gradually lift the film, which can also achieve the effect of heat preservation and moisturizing.

To sow all kinds of plants and flowers, you must choose soil that is loose and breathable, has a certain water-holding capacity, and must be clean and low in fertility. These points are extremely critical.

The simplest method is to use imported peat soil. Pay attention to choosing fine particles. Peat soil is particularly clean, rich in organic matter, and particularly breathable and loose. It has good water retention capacity, which is beneficial to the germination of seeds.

If you feel that peat soil is not environmentally friendly, you can use coconut bran instead. For example, use fine coconut bran mixed with perlite and vermiculite in a ratio of 6:1 or 5:1. You can also mix in a little coarse coconut shell. I also want to remind everyone here. Whether it is fine coconut bran or coarse coconut shell, they are the outer fiber of coconut. Even after industrial desalination treatment, a little salt will remain. Before use, it is recommended to rinse it with clean water more than two or three times. The packaging bags left behind when buying rice are very suitable for cleaning coconut bran.

If you want to increase the water-holding capacity, you can mix some vermiculite on the soil surface or in the soil. Vermiculite is particularly clean and breathable, and the water-holding capacity will be very good.

Next, it is time to germinate the seeds. Different flower seeds have different germination methods. Some seed shells are particularly hard and need to be soaked in warm water to soften the seed shells before sowing (such as nasturtium, etc.). It is recommended that the seeds of most plants be soaked in clean water for 8 to 24 hours, but you should pay attention to cleaning the seeds frequently. When cleaning, be careful not to scatter them. If there is mucus on the seeds, be sure to clean them, such as rosemary seeds. .

After the plant seeds are soaked, they can be sown directly in the soil, or they can continue to germinate. The best way is to prepare some crisper boxes and put some wet paper towels or commonly used paper towels on the crisper boxes. After spraying with water, the seeds can germinate normally. .

Place the seeds on a moist paper towel, fold the paper towel, then cover it and place it in a ventilated and light place. Spray water regularly in the future to keep the paper towel moist and maintain a warm and humid environment.

When the seeds sprout small white roots, they should be spread in the soil in time. Don't wait for the roots to grow too long or even penetrate into the paper towel, which will be difficult to handle.

Some seeds are prone to residual pathogens and are prone to lodging or rotting later. The seeds can be soaked in potassium permanganate solution or carbendazim solution in advance.

During the entire seedling raising period, be sure to keep the soil slightly moist, maintain a warm environment, and maintain good ventilation. After the seedlings grow out, gradually lift off the film or cover.

After the seedlings grow, you must gradually increase the light to allow the seedlings to gradually adapt to the sun, keep the soil moist, and avoid strong winds. Be sure to use relatively fine water when watering to avoid washing the seedlings down.
