The quality of leeks can increase simultaneously with the output

In the production of vegetables, especially leeks, achieving high quality and high yield often seems like a difficult balancing act. However, Li Wanmin, known as the "King of Leeks" from Shouguang City in Shandong Province, has developed effective strategies to overcome this challenge. With years of experience, he emphasizes that proper techniques can ensure both superior quality and increased output. First and foremost, disease prevention is key to achieving high yields. One of the most common issues in leek cultivation is lodging—when the plants fall over due to weak stems or heavy rain. To prevent this, Li recommends using a support system. Wooden poles, about 30 centimeters tall, are placed at intervals of 20 centimeters on either side of the leek rows. Iron wires are then stretched between these poles, with each wire secured every 5 meters using wooden stakes. Between the rows, thin bamboo sticks are laid horizontally along the wires, spaced 20 centimeters apart. This structure allows the leek leaves to grow upright without falling, reducing the risk of damage and disease. Another important measure is controlling insect pests. Li suggests using high-quality insect nets with a mesh size of 18 to 22 threads per inch. These nets effectively block pests while allowing air and light to pass through. Additionally, spreading wood ash around the base of the plants helps prevent tick larvae from hatching, offering a natural and eco-friendly solution to pest management. Lastly, Li introduces the use of a solar wind barrier, a reflective screen designed to enhance light exposure and increase temperature. This technique not only improves plant growth but also helps leeks mature faster, leading to an earlier harvest. The installation involves placing a two-meter-wide reflective film along the northern edge of the leek field. Wooden stakes are inserted every 3 to 5 meters, angled forward at 60 degrees to maximize sunlight reflection. Steel wires are then stretched between the stakes, spaced 10 centimeters apart. The reflective curtain is hung on the north side of the wires, and small bamboo rods are used to secure it tightly, spaced about 30 centimeters apart. This setup ensures optimal conditions for leek development. By combining these methods—strong support structures, effective pest control, and the use of solar wind barriers—Li Wanmin demonstrates how it’s possible to achieve both high quality and high yield in leek farming. His approach not only improves productivity but also promotes sustainable and efficient agricultural practices.

Greenhouse Seedling Bed

A seedbed or seedling bed is the local soil environment in which seeds are planted. Often it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field. A seedling bed is used to increase the number of seeds that germinate.
