Hydroponic Watermelon: a Major Breakthrough In Soilless Cultivation Of Cucurbitaceae Plants

2023-07-04

Recently, a major breakthrough in the agricultural field has attracted widespread attention: using water to cultivate watermelons! The successful application of this technology indicates that the soilless cultivation technology of Cucurbitaceae plants has taken another step forward.

The so-called Cucurbitaceae plants refer to fruits and vegetables such as watermelon, cucumber, pumpkin, loofah, etc. In the past, the cultivation of these plants relied on nutrients in the soil to provide nutrients. However, there are many problems in traditional planting methods, such as soil pollution, waste of land resources, difficulty in Pest control, and so on.

The emergence of hydroponics technology has brought new hope for the planting of Cucurbitaceae plants. Hydroponics technology refers to soaking the roots of plants in a nutrient solution and providing the nutrients needed by the plants through the dissolved nutrients in the water. This method not only avoids soil pollution, but also saves a lot of land resources. In addition, hydroponic cultivation technology can effectively prevent and control diseases and pests, and improve the quality of fruits and vegetables.

Hydroponic Watermelon

However, soilless cultivation of Cucurbitaceae plants is not easy. Due to their well-developed root systems, these plants require a large amount of nutrients to support their growth and development. Therefore, in hydroponic culture technology, the formula and concentration of nutrient solution are crucial. At the same time, attention should also be paid to controlling environmental factors such as water temperature, light, and ventilation to ensure that plants can grow healthily.

Watermelon is a dicotyledonous flowering plant that is a common fruit in people's homes. Watermelon can be hydroponic. In fact, hydroponic watermelons are roughly the same as soil watermelons. Perhaps hydroponic watermelons are sweeter because nutrients can be fully absorbed.

Key points for hydroponic cultivation of watermelon:

1. Cultivating watermelon seedlings is the first step. Water culture seedlings can be raised using the microgreen system, and attention should be paid to sufficient sunlight during seedling cultivation. Wait for about 7-10 days before watermelon seeds begin to sprout. At this point, they need to be separated and only one seedling is left behind.

2. The nutrient solution should be adjusted according to the different growth periods, seasons, and plant performance of watermelon. During the growth period of watermelon, the nitrogen content in the nutrient solution should be appropriately increased, with growth as the center during the fruiting period, and the phosphorus and potassium components should be appropriately increased.

3. After planting, attention should be paid to changing the water, as the dissolved oxygen content planted in high-temperature water culture bottles will decrease, which can easily cause hypoxia in the watermelon root system.

Soilless Cultivation

Precautions for hydroponic watermelon cultivation:

1. Pay attention to frequent water changes, preferably once a week, to ensure better root growth.

2. During hydroponic cultivation, pay attention to frequent exposure to the sun for better photosynthesis.

3. When choosing a hydroponic container, it is important to choose a larger container because watermelon has a well-developed root system and requires sufficient nutrients to meet the growth of the root system. Commonly used hydroponic containers include hydroponic tower systems, NFT systems, or Dutch bucket system for substrate cultivation.

Experts say that using hydroponic cultivation technology to grow watermelon can not only improve yield and quality, but also save land resources and reduce environmental pollution. In the future, soilless cultivation technology will become one of the important directions for agricultural development. We believe that in the near future, we will see more fruit and vegetable products based on hydroponic technology emerge.
