The nutrient solution used in hydroponic vegetables is to dissolve the fertilizer in water and absorb it through the roots of the vegetables to supply the water and nutrients necessary for the growth and development of the vegetables. The preparation and management of nutrient solution is the key technology in hydroponic technology, which plays a decisive role in the growth of vegetables.
Introduction of hydroponic cultivation nutrient solution
The main fertilizers used to prepare nutrient solution are: calcium nitrate, potassium nitrate, nitric acid, magnesium sulfate, potassium silicate, potassium dihydrogen phosphate. Micro-fertilizers include: chelated iron, sodium borate, manganese sulfate, copper sulfate, zinc sulfate, ammonium molybdate. The specific dosage and the concentration ratio of the nutrient solution vary depending on the type and variety of the vegetables, the geographical conditions of the cultivation sites, and the seasons. In the process of cultivation and management, it is necessary to observe and adjust in time according to the actual growth of vegetables.
The nutrient solution not only supplies the water and nutrients necessary for the growth of the vegetables, but also supplies the dissolved oxygen required for the roots of the vegetables to breathe. Therefore, it is necessary to install an aeration facility in the cultivation tank to increase the dissolved oxygen amount in the nutrient solution in time, which is extremely important for the cultivation of hydroponic vegetables.
The update and supplement of nutrient solution is the main work of nutrient solution management in the process of hydroponic vegetable cultivation. In general, fruit and vegetable vegetables need to be renewed two to three times during the entire growth period from planting to harvesting; and leafy vegetables from the time of planting to harvesting, if there is no large area of physiology Diseases, nutrient solution does not need to be updated, just need to supplement the amount of nutrient solution consumed once or twice a week.
Hydroponic sowing seedling precautions
Sowing is usually done in the morning. Prepare the seeder and select the seed before planting. When planting, turn on the power to the seeder, then pour the seeds into the suction cup of the seeder, open the switch, and shake it evenly to allow the seeds to adhere to the holes in the suction cup. Then pour out the extra seeds.
Make sure each hole has seeds and maintain the quality of each seed. The breeding substrate is inverted on the suction cup of the seeder with the side of the hole facing down. Then cover the bottom cover, turn the seeder over, close the switch, and open the bottom cover aside. Seeds were examined in the wells of each breeding substrate. The breeding substrate is transferred to a seedling tray. Place the seedling tray on the nursery table, pour the nutrient solution with a watering can, and let the nutrient solution immerse the breeding substrate.
It is very important to moisturize the seed after sowing. Spray the nutrient solution once or twice a day with a watering can to keep the surface of the seed moist and provide the necessary nutrients for seed germination. Where conditions permit, the tidal table can be used for seedling, and the breeding substrate is infested into the nutrient solution twice a day for 40-60 minutes.
During the breeding period, attention should be paid to the control of the temperature. The illumination should not be too strong. If necessary, the shade net can be used to adjust the illumination. Regular observation and understanding of seed germination and growth. Under normal circumstances, 3-5 days can be germinated and emerged, and 5-7 days are seedlings.
How about the taste of the fruit grown by the LED plant growth lamp?
I used to eat the fruit that was born under the bright sunshine and the rain of nature. I suddenly heard that the melons that I had in my hands were ready to be imported.
If you don’t know anything about this before, you really can’t bite it.
Because you are used to naturally bred food, but also afraid of artificial ripening fruits, you may think that the light emitted by LED plant growth lights is also toxic.
Here, in order to give the LED plant lamp a name, explain the taste and nutrition of the fruit grown by the LED plant growth lamp:
LED plant growth lamps can promote plant growth, and adjust the plant growth cycle according to the needs of the market. Therefore, the fruits grown by LEDs are generally sold fresh, and there are few cases where the time is too long.
The spectrum emitted by LED plant growth lamps is customized according to the needs of plant growth, and promotes the formation of vitamins and other organic substances in plants. Strictly speaking, the plants grown by LED plant growth lamps are more nutritious than ordinary fruits. Be high.
Another point is that most of the light emitted by LED plant lights is visible light, and there is no harm to the human body.
In addition, LED plant growth lights also have a certain effect of deworming and insect resistance. Excluding other external factors, plants planted with LED plant lights are safer and more nutritious! The taste of melons will be better
For example, the role of LED plant lights in flower planting:
1. Adjust the flowering period
2. Strong and beautiful
3. Reduce the proportion of deformed flowers
4. Increase plant height, diameter and weight, etc.
5. Improve the quality of fresh cut flowers
The above is the precautions for hydroponic sowing and seedlings and the introduction of nutrient solution for hydroponic cultivation. If you know more about the plant, please Follow us @VanqLedLight.
