Preparation and use of nutrient solution for hydroponic plants

First of all, let's take a look at the advantages of hydroponic plants compared with soil-cultivated plants.

1. The nutrient solution of hydroponic plants is prepared according to the needs of plant growth, so the flowers cultivated are large and many, strong in taste, colorful and long in florescence.

two。 Hydroponic plants only need to replenish nutrient solution regularly, which is easy to operate, labor-saving and time-saving.

3. Clean, no weeds, few diseases and insect pests.

There are a wide variety of nutrient solutions for hydroponic plants on the market, and for novice hydroponics, fake and shoddy products may be bought carelessly. And in their own home to prepare the nutrient solution, it can not only ensure quality and save money, but also experience the fun of their own DIY.

Before learning to make hydroponic plant nutrient solution, learn how to use it.

1. Vibrating to increase oxygen. Fix the flower plant with one hand and gently shake the vessel with the other for more than 10 times. After shaking, the dissolved oxygen content of the nutrient solution can be increased by about 30%.

two。 Increase the number of water changes. To change water is to change the water in the bottle with nutrient solution. In general, water is changed every 5 to 10 days in spring and autumn, about 5 days in summer, and every 10 to 15 days in winter. Domestic hydroponic flowers should use soft water as water source, and tap water in line with national standards can be used generally. After placing the tap water for two hours to half a day, after its temperature is close to room temperature and the chlorine in the water is volatilized, the bought nutrient solution is added in proportion to become a nutrient solution that can raise hydroponic plants.

3. Add an appropriate amount of "solid oxygen" to the nutrient solution or 1% hydrogen peroxide (3% hydrogen peroxide).

4. Using miniature submersible pump or aeration pump (all standard products of aquarium) to carry out waterfall gas to the nutrient solution, plant roots can obtain sufficient oxygen in such an environment to promote the healthy growth of flowers.

After knowing how to cultivate plant nutrient solution with water, let's learn the preparation of nutrient solution together.

1. The various elements and their dosage used in the preparation of hydroponic plant nutrient solution need to be determined according to the variety, growth and development period and flowering time of the plant, as well as the final growth area. When preparing, the tap water should be placed for two hours to half a day, and after its temperature is close to room temperature and the chlorine in the water is volatilized, the concentrated nutrient solution can be added in proportion to become a nutrient solution that can raise hydroponic plants.

two。 A little bicarbonate also interferes with the absorption of iron by the roots. Therefore, when using tap water to prepare nutrient solution, a small amount of sodium ethylenediamine tetraacetate or humic acid salt should be added to treat chloride and sulfide in the water.

The commonly used amount of nutrient solution: add 0.22 grams of ammonium phosphate, 1.05 grams of potassium nitrate, 0.16 grams of ammonium sulfate and ammonium nitrate, and 0.01 grams of ferrous sulfate to 1 liter of water. Metal containers should not be used for the preparation and storage of nutrient solutions. Ceramic, plastic, glass or ceramic containers are best used.

The most important maintenance of hydroponic plants is to change water for them, and attention should be paid to the addition of nutrient solution when changing water.

1. Tap water can be used for water exchange, but it is best to leave it for one or two days. Mineral water or pure water can be used directly. The temperature difference between raw water and fresh water should not be too large. 6ML bagged nutrient solution is mixed into 2.25L large cola bottle and used. 300ML bottle nutrient solution each bottle cap solution mixed with 2.25L large cola bottle of clear water after use. The shelf life of diluted nutrient water is 6 months, which is usually stored away from the sun.

two。 When it is below 10 degrees in winter and above 35 degrees in midsummer, the concentration of nutrient solution should be reduced (usually the normal 1pm 3-1pm 2) or only cultured in clean water.

The above is a little knowledge about the nutrient solution of hydroponic plants. I hope it can help you in the process of growing hydroponic plants.
