Eggplant is rich in nutrients, including protein, fat, carbohydrates, vitamins, as well as various nutrients such as calcium, phosphorus, and iron. It has excellent performance in preventing aging and lowering cholesterol to protect the cardiovascular system. It is a delicacy and also has good health effects.
Hydroponics is a gradually popular planting method, which has advantages such as saving water, reducing fertilizer usage, and increasing crop yield. As a widely cultivated vegetable, the research on hydroponic cultivation techniques of nightshade crops has always been of great concern.
In recent years, significant breakthroughs have been made in the technology of using hydroponic tower systems to grow eggplants. The hydroponic tower system is a vertical planting system that plants are planted in a tower shaped container and supplied with nutrients and water through a water circulation system, allowing plants to grow vertically. The advantages of this system include small footprint and water saving.
Compared with traditional soil planting, the hydroponic tower system can save more than 70% of water, reduce fertilizer usage by more than 50%, and increase the yield of eggplants by more than 30% compared to traditional planting methods. In addition, the hydroponic tower system can effectively control diseases and pests, making the quality of eggplants even better.
Let's take a look at how to use a hydroponic tower system to grow eggplants. We need to prepare a tower system and some eggplant seedlings. The hydroponic tower system includes a water tank, water pump, timer, and planting basket, etc. The hydroponic tower system has two options: with or without lights, and can be customized according to needs. Eggplant seedlings can be purchased locally or raised through hydroponic cultivation.
Then assemble the tower system according to the instructions and place the water tank at the bottom. Place the planting basket containing eggplant seedlings on the planting holes of the tower system.
Finally, add an appropriate amount of water and nutrient solution to the water tank of the tower system, and power on the water tank to drive the nutrient solution to the roots of the seedlings, continuously circulating.
Special attention should be paid to regularly checking the water level in the water tank and changing the nutrient solution according to different growth cycles. Eggplant seedlings need to be regularly pruned and weeded to maintain a healthy growth state. When the eggplants are ripe, we can gently pick them and enjoy the fresh eggplants.
Planting techniques for hydroponic eggplant:
1. Select eggplant varieties suitable for hydroponic tower system cultivation. Some varieties are more suitable for hydroponic tower cultivation than others.
2. Keep the water quality clean. The pollutants in the nutrient solution may affect the growth and quality of eggplants.
3. Regularly check the condition of the water pump and water tank. If they malfunction, it may cause damage or death to the eggplant.
4. Control the pH and EC values of the nutrient solution. These values should be within the appropriate range to ensure that eggplants can receive sufficient nutrition.
5. Provide sufficient sunlight. Although the hydroponic tower system can be used indoors, eggplants still require sufficient sunlight to grow healthily.
Planting eggplants using a hydroponic tower system is a major breakthrough in hydroponic culture technology for solanaceous crops. This technology not only has the advantages of saving water, reducing fertilizer usage, and increasing crop yield, but also can effectively control pests and diseases, bringing new ideas and methods to agricultural production.
