How can families make their own nutrient solution for potted plants?

In the prescribed volume of nutrient solution, the number of salts containing various essential elements of the nutrient solution is specified. The nutrient solution prepared according to the dosage specified in the formula becomes the stock solution, the standard solution, and its concentration is defined as a dose. Purchase some ordinary nutrient soil, or garden soil, soak in water for 24 hours, collect and control the water, can be precipitated for a long time, take the above clarified water, is the simplest nutrient solution, the amount of water is mastered, how much nutrient solution is needed.

One serving of nutrient soil can be used multiple times. Use daily waste to configure soaking liquid fertilizer according to the current use of nutrient solution formula at home and abroad, the container for filling nutrient solution should use ceramic, plastic or glass materials, not iron products, otherwise the nutrient solution will be invalid. It's best to go with it.

Hydroponic plant nutrient solution formulas are generally divided into two types, these two hydroponic plant nutrient solution formulas are widely used formulas, and are the world's most famous Morad nutrient solution formulas, which are the following two. Liquid a: 125 grams of calcium nitrate, 12 grams of ferrous sulfate.

Add the above to 1 kg of water. Liquid B: 37 grams of magnesium sulfate; ammonium monobasic phosphate 28 g; potassium nitrate 41 g; grams of borate; grams of manganese sulfate; There is also a recipe contributed by netizens for copper sulfate and sulfur:

Add grams of ammonium phosphate, potassium nitrate, ammonium sulfate and ammonium nitrate, and ferrous sulfate grams to one liter of water, and mix evenly to form a hydroponic flower nutrient solution. You can choose your own recipe according to the items you can buy in a store near you, as for what you said, don't use chemical reagents, just use common materials at home to configure, it's really not easy. When preparing the nutrient solution, avoid using metal containers, let alone use it to store the nutrient solution, and it is best to use glass, enamel, and ceramic utensils.

When preparing, it is best to dissolve various inorganic salts separately with a small amount of warm water of 50, and then pour water equivalent to 75% of the specified capacity in the order of the items listed in the formula, stir while pouring, and finally add enough water. If tap water is used in the preparation of nutrient solutions, tap water should be treated, because most of the tap water contains chlorides and sulfides, which are harmful to plants, and some bicarbonates can also hinder the absorption of iron by the roots. Therefore, when preparing a nutrient solution using tap water, a small amount of sodium EDTA2 or humate compounds should be added to treat chlorides and sulfides in the water.

If peat is used as a substrate for soilless cultivation, the above disadvantages can be eliminated. If the quality of groundwater is poor, it can be prepared with unpolluted river or lake water. <>

The culture soil is composed of: garden soil (vegetable garden soil, garden soil), humus soil, river sand, mountain mud, plant ash, sawdust (sawdust), bone meal and other fertilizers in a certain proportion. Different flowers, with different ratios of cultivated soil.

The flowers with fleshy roots are prepared with garden soil and humus soil as the main raw materials; Camellia, orchid, rhododendron and other acid-loving flowers are prepared with humus and mountain mud as the main raw materials; The soil used for the cultivation of cactus pulpy succulents is generally prepared with garden soil, river sand, coal ash and humus. Commonly used nutrient solution formulas 1, sodium nitrate 10 grams, superphosphate 70 grams, ammonium sulfate 25 grams, potassium sulfate 35 grams, magnesium sulfate 40 grams. Usage:

When using the above recipe to prepare the nutrient solution, first mix it with water, and then add the mixed trace elements at a ratio of 3 grams per 100 liters of water before using <>

1. The utensils filled with nutrient solution should be made of plastic or glass materials as much as possible, and iron products should be avoided, otherwise the effect of the nutrient solution will be reduced, and it is best to match with it, according to the size of the plant and the volume of the flower bowl to determine the amount of dosage.

2. After adding the nutrient solution, you can gently shake the utensils with your hands to make the dissolved oxygen content of the nutrient solution improve the use effect of the nutrient solution.

3. Spring and summer are the peak seasons for plant growth, and the amount of fertilizer required is large, and fertilization is generally applied once every 1-2 weeks. In autumn, the amount of fertilizer should be gradually reduced, 1 2 months can be watered 1 time, low temperature in winter, the plant enters the dormant period, stop growing, no need to fertilize, if in a warm room, you can apply less.

4. If the plant has been formed, even in the peak growing season, only a small amount of nutrient solution needs to be watered occasionally. Fertilization should not be too much, otherwise the plant will cause overgrowth, thus destroying the original shape, and the recommended dosage of the nutrient solution should be followed.

5. Hydroponic plants with nutrient solution should be changed frequently, generally once in spring and autumn 5 to 10 days; Change the water about once every 5 days in summer; Change the water every 10 to 15 days in winter.

Rice washing water contains many nutrients, but be careful to ferment it before using it. Put the usual accumulated rice water in a large bottle, screw the cap and put it in the sun for about half a month, then add 50 times the water and stir, and then put it into the bottle for preservation, and it can be used regularly when the water is raised, which is a good nutrient solution.

It is also possible to make a nutrient solution with compound fertilizer. The method is to put the appropriate amount of fertilizer in water, and then stir and dissolve, and then put it in a bottle after it is completely dissolved.

Dig up an appropriate amount of soil from under the fallen leaves in the garden, put it in a pot, fill it with water and stir, then put it in the sun to dry, and stir it again after the water and soil are separated. In this way, the filtered water contains nutrients from the flower soil, which can be used as a nutrient solution to promote the growth of plants.

When cultivating plants in water, it should be noted that the nutrient solution cannot replace adding water and changing water, nor can it be used for a long time to avoid burning the plant and affecting the growth. A small amount should be added regularly, and when the water quality is found to be turbid, it is necessary to change the water, and when the water is less, add clean water and do not add nutrient solution.

1. The nutrient solution is becoming more and more convenient, and the utensils filled with the nutrient solution should be made of ceramic, plastic or glass materials, and iron products cannot be used, otherwise the nutrient solution will be invalid. It's best to go with it.

2. The amount of liquid should be decided according to the size of the plant and the volume of the flower bowl. If the amount is too large, the plant cannot absorb it, and some even cause poisoning; If the amount is insufficient, it will not play a role in promoting growth. The amount of fertilizer applied each time should be about the volume of the flower bowl.

The plant nutrient solution is made of lemon nutrient solution and carbonated drink is made of nutrient solution.

1. Lemon to make nutrient solution

Watering water containing citric acid in the soil can change the properties of the soil to a certain extent, increase the acidity of the soil, and promote the absorption of iron by plants, so that plants can grow healthier. Prepare a few slices of fresh lemon, four tablespoons of white vinegar and a basin of cold water, add the lemon slices and white vinegar to the cold water and stir well, let it sit overnight, and the homemade citric acid is ready!

It is said that this homemade citric acid can not only water flowers, but also clean kitchen utensils after dipping them with a rag, which can effectively remove stains! Watering the flowers is also very simple, take out 10ml each time you use it, add it to 1 liter of water and stir to mix, and then you can use it on the plant!

2. Make nutrient solution from carbonated drinks

The reason why plants like to drink carbonated drinks is actually very simple, the ingredients of carbonated drinks also contain citric acid, which has a promoting effect on the growth of plants. So don't waste the carbonated drinks that you haven't drunk in the future! It's good to make a nutrient solution to water the flowers!

The proportion of carbonated drinks to make nutrient solution is similar to the first method, four spoons of carbonated drinks plus a basin of water stir evenly, let stand for about half a week, and then you can use it to water the flowers!

Precautions for the use of plant nutrient solution:

1. Culture medium

The plant nutrient solution can be used as the culture medium of hydroponic plants, because the nutrient solution is rich in nutrients, which can provide the nutrients needed for the growth of plants, and when hydroponic breeding plants, it is best to replace the culture medium every 10 days, and it should be noted that the concentration of the plant nutrient solution should not be too large.

2. Foliar fertilizer

When cultivating foliage plants, it is necessary to prepare a plastic sprayer or glass bottle, fill it with plant nutrient solution, and dilute the water, and then spray it on the leaves of the plant to make its leaf surface more green and shiny, and the nutrient solution prepared on the same day needs to be used up on the same day, so as not to reduce the fertilizer efficiency.

1. Washing rice water.

Rice washing water contains a variety of nutrients, but it is necessary to pay attention to fermentation before use. Put the accumulated rice water into a large bottle, screw the cap and expose it to the sun for about half a month, then add 50 times of water and stir, and then put it in the bottle for preservation. It can be used regularly when it is in the water.

It's a great nutrient solution.

2. Compound fertilizer.

Compound fertilizers can also be used to make nutrient solutions. The method is to put an appropriate amount of fertilizer into water, then stir to dissolve, and then put it in a bottle for preservation after it is completely dissolved. When the plant is cultivated in water return mold, a small amount of it is dripped into the water, which can promote the growth of the plant, because it contains the nutrients of the flower fertilizer itself, which can make the plant grow more vigorously.

3. Natural nutrient solution.

Dig an appropriate amount of soil from the fallen leaves in the garden, put it in a pot, add water and stir, then dry it in the sun, and then dismantle and bury it after separating the soil and water. The same method can also be stored in a bottle after soil and water separation. The filtered water contains nutrients from the flower soil, which can be used as a nutrient solution to promote plant growth.

4. Precautions.

Note: The nutrient solution cannot replace adding and changing water, nor can it be used for a long time, so as not to burn the plant and affect the growth. It should be added in small quantities at regular intervals. When the water is turbid, it's time to change the water. When the water level is low, the nutrient solution is not allowed to be added to the clean water.

1. How to use hydroponic plant nutrient solution.

1.Vibration oxygenation. Fix the flower plant with one hand, and gently shake the vessel with the other hand more than 10 times. The dissolved oxygen content of the nutrient solution after shaking can be increased by about 30%.

2.Increase the number of water changes. A water change is a change of water in a bottle with a nutrient solution.

In general, change the water once every 5 to 10 days in spring and autumn; Change the water about once every 5 days in summer; Change the water every 10 to 15 days in winter. Domestic hydroponic flowers should use soft water as the water source, and tap water that meets national standards can generally be used. After leaving the tap water for two hours to half a day, when its temperature is close to room temperature and the chlorine in the water has volatilized, then add the purchased nutrient solution in proportion to become a nutrient solution that can raise hydroponic plants.

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

4.The nutrient solution is waterwatered by a miniature submersible pump or an aeration pump (both standard products of the aquarium), and the plant roots can obtain sufficient oxygen in such an environment to promote the healthy growth of flowers.

2. Hydroponic plant nutrient solution formula.

The various elements used in the preparation of hydroponic plant nutrient solution and their dosage need to be determined according to the variety of plants planted, the growth and flowering period, and the final growth area.

Preparation method of hydroponic plant nutrient solution:

Add grams of ammonium phosphate, grams of potassium nitrate, grams of ammonium sulfate and ammonium nitrate, and grams of ferrous sulfate to 1 liter of water, and mix well to form a nutrient solution. Metal containers should not be used for the preparation and storage of nutrient solutions, preferably ceramic, plastic, glass or ceramic containers.

Usage: Potted plants are watered with nutrient solution once a week during the growing season, and the dosage can be flexibly mastered according to the size of the plant.

Wrap the soil in gauze and soak it in water.
