A Detailed Guide to Soilless Cultivation Methods and Techniques for Vegetables
As planting techniques continue to improve, many regions now use soilless cultivation to grow vegetables; it is not only clean and environmentally friendly, but also saves a lot of cost. So what is soilless vegetable cultivation?
I. What is soilless vegetable cultivation?
Soilless vegetable cultivation is the cultivation of vegetables without soil. It can obtain nutrients through a mineral nutrient solution; this method saves water, and as long as the nutrient solution is sufficient, it can produce a high yield. Vegetables that can currently be grown soillessly include cucumber, tomato, water spinach, ginger and others.
II. What are the benefits of soilless cultivation?
1. It is not limited by seasons and can grow various crops throughout all four seasons of the year.
2. Soilless cultivation techniques can meet the needs of crop growth by monitoring and adjusting the nutrients in the water, precisely control plant growth, and avoid excessive vegetative growth.
3. In a hydroponic system, the water in the hydroponics can be circulated and reused, which can reduce water use and save water.
4. Soilless cultivation of crops does not require the use of chemical agents, chemical fertilizers and the like, providing a sterile environment for crop growth.
5. Soilless cultivation crops grow quickly, yields increase, there is no trouble of soil setup and testing, and space is fully utilized.
6. Compared with traditional planting methods, crops grown soillessly have 50% more vitamins than those grown traditionally, and have very high nutritional value.
III. Which vegetables can be grown soillessly?
1. Tomato
Tomatoes can be grown soillessly throughout all four seasons of the year. Generally, soilless tomato cultivation in solar greenhouses is used. When cultivating in a greenhouse, the crop rotation arrangement needs to be specifically determined according to the greenhouse's performance; tomato production is mainly based on the winter-spring crop and the early spring crop.
2. Bitter melon
Bitter melon is a plant of the genus Momordica in the Cucurbitaceae family. Its fruit tastes sweet and bitter. It is mainly used as a vegetable and can also be candied. It is grown in both the north and south, has low requirements for the cultivation environment, and has advantages such as vigorous growth, strong fruit-setting ability and a long harvest period, making it very suitable for soilless cultivation.
3. Eggplant
In recent years, most eggplant cultivation has used solar greenhouses and plastic tunnel cultivation, but because of continuous cropping on the same land, soil-borne diseases have become increasingly serious, and the use of soilless cultivation techniques can overcome soil-borne diseases.
4. Ginger
In traditional planting models, continuous cropping leads to a large amount of soil residue, and the ginger blast pathogen cannot be eliminated, causing infection with ginger blast during the growth and planting process, while the use of soilless cultivation techniques can effectively solve this problem.
5. Cucumber
Cucumbers are easily harmed by pests and diseases during the planting process, while the use of soilless cultivation techniques can not only effectively avoid pest and disease damage and soil transmission, but also reduce the amount of pesticides used, improve crop quality and yield, and has advantages such as saving fertilizer and labor and not being limited by land fertility.
