Planting technique of Chinese chive in hydroponic culture

Many vegetables can be hydroponic, hydroponic culture also has many advantages, reducing diseases and insect pests, saving space, saving planting time and so on are the benefits of hydroponics. Leek maggots often do harm to Chinese chives when planted in soil, and they often do harm in the field, and continue to do harm after laying eggs in the roots of leek. But hydroponics can just solve this problem. So how to cultivate chives in hydroponics, how to carry out them, we can learn about the contents of hydroponics.

1. Preparation for sowing

Prepare to clean vermiculite, then soak it with medicament, rinse clean, soak for a day before use. Soak the seeds with about 40 degrees hot water, stir and soak to avoid scald, the water temperature will gradually drop, after the drop, continue to soak the seeds for a day, fish out and rinse, after draining, use wet gauze to wrap around 18 degrees to accelerate germination, wash the mucus every day, and show white in a few days.

2. Sowing method

Cover the seedling tray with wet papyrus, covering each hole, but fit the tray, and then sow two seeds in each hole. Then cover the papyrus so that the seeds are not exposed. Finally, vermiculite is placed on the papyrus and laid evenly, so that it can be moisturized and insulated, forming a unique environment, so that the seeds will break through the papyrus and grow out. The papyrus is not easy to break, but the seeds can pass through.

2. Post-broadcast management

Seeds need to keep about 60% to 70% water, and the water retention of river sand is good, but it is not as good as that of soil, so you can water and spray more frequently. Don't be too dry before watering. The temperature is kept at 20 degrees, not more than 25 degrees. If the temperature exceeds the germination rate, it will be affected and the germination rate will decrease. Especially if it is more than 30 degrees, it may not germinate smoothly. After sowing, the surface can be covered with papyrus, which can keep warm and wet, and the seedling tray can be placed in the greenhouse for management.

3. Transplanting and planting

Using a special fixed plate of custom leek, remove the seedlings, clean the river sand from the roots, then fix it to the planting plate, and install the prepared nutrient solution in the nutrition trough. Install nutrient solution reflux equipment to prevent nutrient solution from rotting roots due to lack of oxygen for too long. There has to be a circulatory system. The nutrient solution must have a disinfection system.

Hydroponic leek is mainly a unique method of raising seedlings, so as to ensure the good germination of seeds. Sowing and planting to manage the temperature is very important, the right temperature and moisture to promote the growth of leek.
