How to grow hydroponic vegetables? Sharing the latest simple method
Hydroponic vegetables are a vegetable-growing technique that has emerged in recent years, and it can also be called soilless cultivation. Especially in cities, where land resources are basically very scarce, the method of growing hydroponic vegetables is also very popular in cities. Many people think hydroponic vegetables are difficult to grow, so today the editor will teach everyone a simple method for growing hydroponic vegetables. Let's take a look below.
1. Building the hydroponic box
When preparing for hydroponic planting, we first need to build the hydroponic box, which is the most basic equipment for growing hydroponic vegetables. The hydroponic box is an opaque water tank, and we can use a basin, a jar, a wooden box, a foam plastic box, etc. The best material among these is the foam plastic box, then build foam plastic of the same or length on the foam plastic box, and then drill holes in the foam plastic at a certain distance, used to place the small bowls or small cups for growing vegetables, etc.
2. Preparing the nutrient solution
Preparing the nutrient solution for hydroponic vegetable growing is the key to vegetable growth and survival. There are also specialized nutrient solutions sold on the market now, but for growing vegetables on a large scale, the required nutrient solution is relatively large, which will increase the cost of growing, so we need to prepare it ourselves. There are many formulas for the nutrient solution, and the most commonly used one is generally prepared in the ratio of 0.568 g potassium nitrate, 0.710 g calcium nitrate, 0.142 g ammonium phosphate, 0.284 g magnesium sulfate, 0.112 g ferric chloride, 0.00284 g potassium iodide, and 0.00056 g each of boric acid, zinc sulfate, and manganese sulfate per 1 liter of water.
3. Raising seedlings in a substrate
For vegetables, we can use nutrient soil to raise seedlings, and when the seedlings grow two or three true leaves, then they can be transplanted and planted. The seedling-raising substrate is generally prepared from peat and furnace ash in a 1:1 ratio. Then sprinkle the substrate on the seedling bed and carry out seedling raising, and when the seedlings grow to a certain size, put an appropriate amount of substrate into the planting cup, move the seedlings into the planting cup, and put in an appropriate amount of substrate to plant them.
4. Planting the seedlings
After the seedlings are placed into the planting cups, we need to add an appropriate amount of nutrient solution to the hydroponic box, and then place the planting cups on the foam plastic floating board for cultivation. Each small hole corresponds to one planting cup, and then adjust the liquid level height of the nutrient solution, generally using just touching the bottom of the planting cup as the standard. There should not be too much or too little nutrient solution; too much will cause the vegetables to die from excess fertilizer, while too little means the vegetables cannot absorb it, which will also cause death.
5. Later-stage management
The later-stage management of hydroponic vegetables directly determines the yield and quality of the vegetables. The management of hydroponic vegetables is actually relatively simple, because it does not require intertillage and weeding, nor watering, nor fertilizing. It only requires reasonably controlling the concentration of the nutrient solution, as well as the growing temperature and light. So we only need to reduce the concentration of the nutrient solution when the temperature is relatively high, and ensure that the liquid level of the nutrient solution is kept at the bottom of the planting cups.
The above is the simple method for hydroponic vegetables that the editor has brought to everyone, hoping it can be helpful to everyone, and at the same time, if you want to learn more detailed growing techniques for hydroponic vegetables, remember to leave a message for the editor.
