First: Why Is the Tray Seedling Planter so Popular?
Nutrient soil is used as the substrate when using the nursery seedling machine. Generally speaking, nutrient soil must be fertile and nutrient complete, followed by conditions such as looseness and good aeration, suitable pH, and so on. Of course, nutrient soil does not contain harmful substances and salt, nor will it endanger the pathogenic bacteria and pests of seedlings. This greatly improves the survival rate of seedlings, so it is very popular.
The quality of different types of seedling substrates varies greatly. We should choose a substrate with many voids, good ventilation, and good water absorption and water retention. In this way, day and night temperature changes are small, and in winter and spring, it is beneficial to keeping warm at night; in summer, the root temperature is not easy to rise, and the crop yield is high. So who can not like the seedling machine?
Second: Preparation before Nursery
Drying: The seeds stored in the winter generally have higher water content. You should sun the seed on the sunny days before nursery to reduce the water content of the seeds, promote the after-ripening of the seeds, and can kill insects and sterilize them.
Seed soaking: Seeds with thin coats such as cabbage, cauliflower, spinach, celery, etc. can be soaked in water at 20-30 degrees Celsius, the first two can be soaked for 3-4 hours, spinach seed soaked for 8-10 hours, celery seed soaked for 1 -1.5 days.
Soak seeds in warm water: melons such as cucumber, winter melon, pumpkin, zucchini, loofah, bitter gourd, snake gourd, etc. Solanum fruits, peppers, eggplants, tomatoes, and other seeds can be used with 55 degrees Celsius of warm water, and continue to add warm water to maintain 55 degrees for 10 minutes, when it drops to 30 degrees, you can continue to soak seed in the water at about 20 degrees, thin skin melon seeds soak for 5 hours, thick-skinned melon seeds soaks for one day, solanum fruits seeds soak for half a day to one day.
Hot water soaking: Seeds with waxy, mucus, thick coat and slow water absorption can be soaked in hot water. The method is to soak the seeds in cold water, then pour into 70-80 degrees Celsius hot water, and stir for 1-2 minutes, then lower the temperature to 30 degrees Celsius, and soak until the seeds have no dry cores.
Seed disinfection: Soak the seeds with 40% formalin 100 times solution for 15 minutes. After removing them, cover them with wet gauze for 2-3 hours, and then control dry and to the seedling.
Third: How to Choose a Seedling Machine
When purchasing a tray seedling machine, you must choose a strong manufacturer, because the entire device of the nursery seedling machine is composed of some small parts, not only in terms of design but also in terms of material selection. Both in operation and in the overall operation process, the comprehensive strength of the manufacturer is demonstrated. In addition, it is the professional, and good manufacturers will provide technical assistance during your later use. The quality of the entire device cannot be neglected because of the price.
