Hydroponics is a new method of indoor soilless cultivation of plants, also known as nutrient solution cultivation, which can make plants grow normally and complete their whole life cycle. Now, we will share the introduction of hydroponics.

Introduction to methods of increasing oxygen and increasing fertilizer for hydroponic plants 1 1. Methods of increasing fertilizer for hydroponic plants

The domestic hydroponic flowers must use special nutrient solution with low concentration, mainly nitrate nitrogen fertilizer. General hydroponic flower nutrient solution contains all the nutrient elements necessary for flower growth, and the proportion of each element is balanced. Inorganic salts are in ionic state, which is suitable for the needs of different flower varieties and their growth and development stages, non-toxic, harmless, and suitable for nutrient absorption.

Increase the frequency of changing nutrient solution

Generally, you can use the special nutrient solution for hydroponics sold in the market. Prepare a suitable concentration according to the instructions, such as diluting 400 times or 1000 times. Don't get the proportions wrong. When preparing, tap water should be allowed to stand for two hours to half a day. When the temperature is close to room temperature and chlorine in the water is completely volatilized, concentrated nutrient solution is added in proportion to become the nutrient solution for hydroponic plants.

Second, hydroponic plant oxygenation method

The water content of domestic hydroponic flowers is in a static state, and the dissolved oxygen is low, which is not conducive to the growth of flowers. The following methods can be used to increase dissolved oxygen.

Vibrate and increase oxygen, fix the flower plant with one hand and gently shake the vessel with the other hand 10 times or more. The dissolved oxygen content of the nutrient solution can be increased by about 30% after shaking.

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

Using micro submersible pump or oxygen pump (both are aquarium standard products) to aerate nutrient solution, plant roots can get enough oxygen in this environment to promote the robust growth of flowers.

Changing water means changing the water in the bottle into nutrient solution. Generally, water is changed every 5- 10 days in spring and autumn; Change water every five days in summer; Change the water every 10- 15 days in winter (after the tap water is left for half a day, add concentrated nutrient solution in proportion).

Changing water is to ensure the oxygen supply in the water. Fresh water contains more oxygen, and plants will grow healthier. If the water is not changed for a long time, plants can persist for a period of time. For example, sometimes people are away from home for ten days, half a month or even a month on business or vacation. Plants cultivated in the soil can't stand it and die.

Hydroponics can persist as long as more water is added; But if the time is too long, the water in the bottle will taste or deteriorate, which will affect the growth of hydroponic plants and even lead to their death in serious cases.

Note: When changing water, please expose the roots of plants by half or one third.

Plants also need to metabolize, breathe oxygen and release nitrogen dioxide, so when you cultivate hydroponic plants, you must master the time and times of fattening, and don't ignore the methods of treating fertilizer damage and increasing oxygen.

Introduction to methods of increasing oxygen and increasing fertilizer for hydroponic plants II. A coup for the maintenance of hydroponic flowers

1, selection of placement position

According to the living habits of flowers, choose the correct placement position, such as: evergreen should not be exposed to the sun, like shade, can be placed in the semi-shade; The octagonal gold plate is easy to burn when exposed in summer, and it is most suitable to be placed in a bright room; Lotus likes light, so we should put them in a sunny place so that they can bask in the sun at any time.

Step 2 change water skills

The most important thing for hydroponic flowers is water, so it is very important to change water regularly.

Before cuttage hydroponic plants take root: change it once a day to keep the oxygen content in the water and promote rooting.

After hydroponics of peanut roots: change the water regularly, usually once every 10- 15. In summer, plants with higher temperature need more water, so change the water once a week.

3. Pay attention to pest control and cold protection.

If the leaves turn yellow or wither, pay attention to whether there are pests and diseases, and remove the withered leaves in time. At the same time, when winter comes, we should keep warm to prevent frostbite.

Second, fertilization management of hydroponic flowers

Although water contains various minerals and trace elements, it is not enough to meet the growth of plants, so we need to fertilize hydroponic flowers regularly. The fertilizer selected here is a nutrient solution composed of various nutrient elements, which is rich in nitrogen, phosphorus, potassium and other trace elements needed by flowers.

Fertilization should follow the principle of "less diligent application" and generally be carried out at the same time as changing water. Every time you change water, you should supplement nutrient solution to make up for the shortage of fertilizer.

Different flowers have different fertilization amounts and laws. Generally, plants with thin roots have poor fertilizer tolerance, and the solubility of nutrient solution is lower, so you can't add too much at a time. Ornamental flowers have a great demand for nitrogen fertilizer, so the required fertilizer is based on the principle of "nitrogen is the main factor, supplemented by phosphorus and potassium".

The above has briefly introduced the very important management measures of hydroponic flowers. As long as you do the above measures, your flowers will show great vitality.

When plants are cultured in water, clean glass bottles should be selected, and the bottle mouth size and bottle depth should be adjusted according to specific plant species. Ensure the water quality is clean and pollution-free, and change the water frequently on weekdays. The height of the water level should be controlled, and the roots or bulbs should not be completely immersed in the water, so the plants will not be able to absorb oxygen. Proper addition of nutrient solution can increase the growth ability of hydroponic plants.

1, water bottle selection

Since it is a hydroponic plant, it is usually better to use glass bottles as vases. On the one hand, it looks beautiful, on the other hand, the transparent vase can monitor the water quality and rhizome growth in the hydroponic environment. The size and depth of specific vases should be adjusted according to the needs of plants.

2. Water quality selection

When maintaining plants in hydroponics, the water quality must be clean and pollution-free, and impurities and microorganisms cannot be left behind. Clean rainwater, snow water or pure water and mineral water collected in nature all have good effects. If aquaculture is carried out with tap water, chlorine will volatilize after standing for 1~2 days. You must change the water quality frequently on weekdays.

3. Water level height

When hydroponic plants are put into vases for maintenance, the choice of hydroponics is also very important. The roots of plants cannot be completely immersed in water, so it is better to leave one third or two thirds in the air, otherwise the ability of roots or bulbs to absorb oxygen will decrease, and finally hydroponics will fail because of lack of oxygen.

4, nutrient solution

Nutrient solution can be understood as fertilizer used in soil culture. You can easily buy special nutrient solution for hydroponics in the market. According to the instructions and the growth status of their own plants, they can be added appropriately to improve the growth ability of hydroponic plants.
