1, making hydroponics box

Before planting hydroponic vegetables, you should prepare a watertight hydroponic box. It is recommended that you use a plastic foam box. It is also necessary to put floating boards of the same size on the box to carry vegetables.

Step 2: Treat vegetables.

Vegetables should be treated simply before hydroponics planting. First of all, choose hydroponic vegetables and wash the roots with clear water. Then comb its roots, cut off its dead roots with scissors, and then disinfect it with potassium permanganate. Disinfected roots cannot be directly cultured in water, so they should be washed with clear water before planting.

3. Hydroponics

Be careful when planting to avoid damaging its roots. It is best to add an appropriate amount of nutrient solution to the hydroponics box. Plant the roots of the seedlings well, and there should always be water in the hydroponic box.

4. Planting and maintenance

Pay attention to changing water after planting, because there will be many bacteria in water during hydroponics, and the water quality will become worse after a long time. So pay attention to changing water, such as rain, pond water or river water.

Extended data:

Nutrient solution preparation is the core technology of normal growth of hydroponic vegetables. At the same time, it is also the foundation and key of soilless culture. According to the demand of plant growth for nutrients, the solution made by dissolving a certain amount of fertilizer in water in an appropriate proportion is called nutrient solution.

The success of hydroponics depends largely on the formula and concentration of nutrient solution, the proportion of various nutrient elements, pH value and liquid temperature, and whether the nutrient solution management during plant growth can meet the requirements of different growth stages.

Only by adopting the correct formula, preparing and managing the nutrient solution according to the appropriate method, can plants be in the most suitable nutrient solution environment at any stage of growth and development, and plants can use more energy to grow, blossom and bear fruit, so as to obtain fast, high-yield and high-quality cultivation results.

Only by deeply understanding the composition principle, change law and regulation method of nutrient solution can we truly grasp the essence of hydroponics. The configuration and management of nutrient solution is by no means a simple mechanical way to take the existing formula and dissolve several fertilizers in water according to the formula.

Because different water quality, cultivation methods, climatic conditions and cultivation period have great influence on the preparation and use of nutrient solution. Only by preparing and using nutrient solution correctly and flexibly and practicing seriously can we achieve the success of cultivation.
