Hydroponic plant nutrient solution, preparation of hydroponic plant nutrient solution
The most important thing for hydroponic plants is the hydroponic plant nutrient solution; the nutrient solution is the energy supply station for plant growth. When plants live in soil, they also rely on the roots to reabsorb energy and mineral elements from the water in the soil. Therefore, hydroponic plant nutrient solution needs to have energy and mineral elements added. Below, the editor will share with you the preparation method of hydroponic plant nutrient solution.
First, we need to understand that soilless cultivation plants have the following advantages compared with soil-cultivated plants:
(1) The nutrient solution for soilless cultivation plants is formulated according to the growth needs of the plants, so the flowers cultivated are large and numerous, with a strong fragrance, bright colors, and a long flowering period. (2) For soilless cultivation plants, you only need to regularly supplement the plants with nutrient solution, which is simple to operate and saves labor and time. (3) Clean, free of weeds, and with few pests and diseases.
For soilless cultivation of plants, the following two points should be mainly grasped:
I. Substrate preparation. Hydroponic plants are mainly fixed on the cultivation liquid container, with the roots placed in the liquid. The hydroponic substrates commonly used at present are: (1) Sand particles with a diameter of less than 3 mm. (2) Natural gravel, pumice, volcanic rock, etc. with a diameter greater than 3 mm. (3) Vermiculite, a mica-type mineral with good buffering capacity that does not sink in water. (4) Perlite. Using it mixed with mudstone and sand gives better results. (5) Peat with good air permeability and strong water-holding capacity. It can be used alone as a substrate or mixed with cinder, etc. In addition, cinder, bricks, charcoal, asbestos, sawdust, fern roots, bark, etc. can all be used as substrates. The substrate should be washed and disinfected before use.
II. Nutrient solution preparation。
What various elements and their amounts are used when preparing hydroponic plant nutrient solution must be determined according to the variety of the planted plant, its growth and development stage, flowering time, and the final growing region.
Preparation method of hydroponic plant nutrient solution：
Add 0.22 g of ammonium phosphate, 1.05 g of potassium nitrate, 0.16 g each of ammonium sulfate and ammonium nitrate, and 0.01 g of ferrous sulfate to 1 liter of water, and mix evenly to obtain the nutrient solution. Metal containers must not be used for preparing and storing nutrient solution; it is best to use ceramic, plastic, glass, or ceramic containers.
Usage: For potted flowers during the growing period, apply the nutrient solution once a week, and the amount can be flexibly controlled according to the size of the plant.

Hydroponic plant nutrient solution Hydroponic plant nutrient solution formula
As hydroponic plants become more and more common, there are also more and more formulas for hydroponic plant nutrient solution. The nutrients plants need differ, so the formulas also vary greatly. Let us take a look together at what should be noted when preparing a formula.
Hydroponic plants simulate the scene of plants growing in soil by adding nutrient solution to water. Therefore, when preparing nutrient solution, you should first understand the habits of the plant, which nutrients it needs more of and which nutrients it needs less of. "Adapt measures to local conditions" and "teach students according to their aptitude" are the only ways to achieve the best plant growth. This achieves the advantages of good quality hydroponic plants and saving labor and time. The nutrient elements plants commonly need include 13 essential elements such as N, P, K, Ca, Mg, S, Mn, Mo, Cu, Fe, Zn, C, H, O, CI, etc. At this point, your chemistry skills are put to the test, because nutrient solution is not a fusion of a single chemical element, but a mixture of elements. Generally, we use compound nutrient solutions; it is just that for each type of plant, the emphasis on nutrients differs, with only slight differences.
MacroelementsIn general, calcium nitrate, potassium nitrate, ammonium nitrate, ammonium sulfate, iron salt solution, etc. are basically used in different proportions to achieve the effect of providing nutrition. Macroelements must be in an ionic state to be absorbed by plants, and the spacing between ions must be appropriate. Therefore, the nutrient solution must not be heated or refrigerated during use.
Trace elementsIn general, boric acid, manganese chloride tetrahydrate, zinc sulfate heptahydrate, and copper sulfate pentahydrate are the main preparation elements, and about 1 milliliter of trace element solution should be added to each liter of culture solution.
The elements'PH valueis also quite important. The PH value represents the acidity or alkalinity of the solution. Some plants prefer alkalinity, and some prefer acidity. Being too acidic or too alkaline will cause the plants to die. Generally, adjusting the PH value to neutral and slightly acidic or neutral and slightly alkaline is sufficient.
Finally, there is theconcentration of the culture solution. After preparing the culture solution, add an appropriate amount of tap water or distilled water. What is this appropriate measure? It is roughly 10 milliliters of nutrient solution dissolved in 1 kilogram of water, depending on the specific characteristics of the plant. After preparation is complete, feed your beloved plants. You can first conduct comparative experiments by adding or reducing ingredients such as zinc sulfate or ferrous sulfate according to different plants and plant characteristics based on existing ratios, and then use the optimal ratio. (Warm reminder: because it is soilless, be sure to secure your precious plants.)
Today, as soilless cultivation technology becomes more and more mature, many plants have taken the water route. Do you also want to prepare the nutrient solution for your favorite plants with your own hands and join the large family of hydroponic plant cultivators?
