How do cucumbers grow without soil? At present, there are many vegetable varieties in China that have already carried out soilless cultivation mode. The following series of Huinong.com will bring you a detailed explanation of soilless cultivation of cucumber. If you are interested, you can take a look.
Seed treatment
Before the cucumber is soiled, the seeds should be treated. The treatment method is usually hot water, the water temperature is 55-65 degrees Celsius, and after 10 to 15 minutes, cold water is added to keep the water temperature at about 30 degrees. After soaking for another five to eight hours, remove the seeds and finally wrap the seeds in cotton cloth and germination at a suitable temperature.
2. Sowing, seedling
After the cucumber seeds are germinated, they can be placed in a soilless tray for seedlings. One or two seeds can be placed in each acupoint. Sprinkle with a layer of vermiculite and charcoal, and finally water with water.
3. Colonization
The planting bed and nutrient solution must be well prepared before planting. Here, we must pay attention to see if the nutrient solution can be transported normally. When the cucumber seedlings grow three to four true leaves, the cucumber seedlings are carefully taken out from the chassis and transplanted into the cultivation bed. Remember to pour water once after planting.
4. Seedling management
The concentration of nutrient solution is very important for the management of seedling stage. Because the growth rate of seedlings in cucumber soilless cultivation is faster, it is easy to age, and 400-500 ml of nutrient solution should be poured every day after planting. The developmental stage should be poured to 2000-2500 mL every day, and the concentration of nutrient solution can be appropriately reduced after the development of cucumber seedlings is completed. The temperature should be kept at 15 to 25 degrees. When the cucumber plant grows to 15-20 cm, the scaffold should be installed in the greenhouse, and the cucumber seedlings should grow along the scaffold.
5. Pest control
The most common pests and diseases of soilless cucumber cultivation are aphids and powdery mildew. Downy mildew, whitefly, etc. Downy mildew is generally controlled by Plex, and powdery mildew is controlled by powder rust. Insect pests use professional anti-insect remedies, and everyone should remember to remove the dead yellow leaves in time.
The above is the key point of cucumber soilless cultivation. I like friends who can look at it more. I hope that more comprehensive technical farmers will come to Huinong.com to share their experiences!
