Detailed Explanation of the Key Points of Soilless Cultivation Techniques for Water Spinach

With the advancement of science and technology, agricultural planting techniques are also constantly developing, and the most distinctive of these is soilless cultivation technology, which can both save planting costs and achieve high-yield, high-quality results. So how should soilless cultivation of water spinach be carried out? Come to Qinnong Web and take a look at the soilless cultivation techniques for water spinach.

1. Planting Preparation

Soilless cultivation is different from traditional planting methods. It requires special planting equipment—growing troughs, which can be purchased directly or built yourself. Generally, the growing troughs are 30 cm high and 50 cm wide. Another important thing is the preparation of the cultivation substrate, which can be made by mixing coal cinders or furnace slag from daily life with chicken manure, NPK compound fertilizer, and organic fertilizer, then piling it up to compost and filling the troughs. When filling the troughs, first spread a 5 cm thick layer of sand at the bottom of the trough, then fill in the prepared substrate, level the substrate, and be careful not to make it too compact. The thickness should be uniform. Then water it thoroughly with a large amount of water, wait until the water has completely seeped down, cover with film for half a month, and then it can be planted.

2. Sowing and Raising Seedlings

Before sowing, to ensure the germination rate, first treat the seeds by soaking them in warm water within 60 degrees for half an hour, then remove them and soak them in clean water for 24 hours, then wrap the seeds in a wet gauze and place them in a greenhouse environment to promote germination. Open and rinse them once a day with warm water, and sow once the seeds show white sprouts. When sowing, choose a substrate with good air permeability, cover with a layer of sand and gravel after sowing, then cover with film to keep warm and moist, maintaining the temperature at about 25 degrees. Seedlings will emerge in about half a month. After the seedlings emerge, remove the film in time to increase air permeability. When the seedlings grow to about 12 cm, they can be transplanted.

3. Transplanting

For transplanting, control the plant and row spacing at about 15×15. When transplanting, pay attention to the time and climate. Generally, transplant in the afternoon, and be sure not to do it at noon when the sun is strongest or in rainy weather. Before transplanting, water the cultivation substrate thoroughly once, and after the water has penetrated, transplant the seedlings, burying 2-3 stem nodes of the seedlings deeply.

4. Management

Water spinach is a vegetable that can be harvested continuously multiple times a year. In order to allow it to grow rapidly after harvest, generally a base fertilizer should be applied after each harvest to ensure the nutrients needed for its growth. After each harvest, urea can be applied as a top dressing. In addition, water spinach has a relatively large water requirement during cultivation, so it should be watered frequently to replenish moisture, and when watering, water thoroughly. Soilless-cultivated water spinach has fewer pests and diseases, but pest and disease control should still be noted.

The above is the soilless cultivation technique for water spinach brought to you by Qinnong Web. Soilless cultivation is a new type of planting technology, especially suitable for growing vegetables at home in cities. We hope it can help you.
