What are the precautions for growing vegetables by hydroponics?

Hydroponic vegetables are really not easy to grow, the requirements for planting technology are very high, and the investment is also very large, so the planting area of hydroponic vegetables is very small at present, and the total area of hydroponic vegetables nationwide does not exceed 5000 10000 acresIf it is used for sales, there are many varieties that can be planted, and the more popular vegetables in the market are lettuce, celery, coriander, these vegetables are loved by the masses, and the sales volume in the market is also good.

<> most leafy vegetables can be grown hydroponically. Leafy vegetables, the growth cycle is short, from planting to harvesting, two or three months, only need to be planted with a nutrient solution, no need to replace halfway. Therefore, hydroponic vegetables are generally leafy vegetables.

Pay attention when watering, because tap water has no nutrients, you can use some organic fertilizer to enhance the nutrients, water fertilizer and the like to pour water spinach on top. Water spinach should be placed in a sunny place, and the balcony is a good site, and shallow water cultivation is cultivated using shallow water fields or shallow ponds. Before planting, the water is drained, the soil is prepared, weeds are removed, and then cuttings are taken.

The cuttings are about 20 cm long, and are inserted diagonally into 2 3 sections at an interval distance of about 26 cm, and the depth is about 3 cm

Use ordinary tap well water hydroponic vegetables, this is relatively simple, especially suitable for ordinary families, buy a few yuan hydroponic trays and seeds. This hydroponic method uses the nutrients of plant seeds to grow into seedlings, and the cycle is short and the technology is simple. The cultivation pond is generally made of cement, and its shape and size are different according to the types of different vegetables, and the cultivation pond for cultivating leafy vegetables is generally larger, and the cultivation pond also has a ditch type and a pipeline type.

In fact, hydroponic vegetables are not very different from the vegetables that are usually planted in terms of fertilizer absorption, even if they are planted in the soil, fertilizer, they must be in the form of ions to be absorbed, hydroponic vegetables grow faster, it is in accordance with the nutrients required by various plant growth stages, so that the roots and leaves of plants can absorb various nutrients at the same time, and the growth rate is much higher than that of substrate cultivation, which can shorten the production cycle.

The first and most important thing for hydroponic green vegetables is the nutrient absorption of hydroponic green vegetables and the environment in which it grows normally, the first is to ensure the quality of the nutrients absorbed by the vegetables, which is generally the best formula for one liter of water potassium nitrate, calcium nitrate, ammonium phosphate, magnesium sulfate, ferric chloride, potassium iodide, boric acid, zinc sulfate, manganese sulfate. Then put the vegetable seedlings to be cultivated in the configured container, put all its roots into the water, make a few small holes on the floating plate of the container, which is conducive to the circulation of air in the container, so as to better promote the rapid growth of vegetable seedlings, and then add an appropriate amount of nutrient solution, and then put it in a position with better gout for breeding and maintenance.

1. When preparing the nutrient solution, avoid using metal containers, and it is best to use glass, enamel, and ceramic utensils.

2. First use a small amount of warm water of 50 to dissolve various inorganic salts separately, and then configure according to the recipe, stirring while pouring.

3. When using tap water to prepare nutrient solution, a small amount of sodium ethylenediaminetetraacetic acid or humate compounds should be added to treat chlorides and sulfides in the water.

1.When preparing the nutrient solution, avoid using metal containers, preferably glass, enamel, and ceramic utensils.

2.When preparing the nutrient solution with tap water, a small amount of sodium EDTA or humate compounds should be added to treat chlorides and sulfides in the water.

1. First of all, hydroponic vegetables are put in the nutrient solution, and the nutrients of the vegetables are obtained through the nutrient solution, although the growth cycle of the vegetables through hydroponics is shortened, but the nutrients contained in them remain unchanged.

2. For hydroponic vegetables and wild vegetables, we also need some tools, if the planting tools can be made by themselves, you can make them yourself, if not, we can go to the Internet to buy, it is very practical to buy online, and generally do not need to manage after cultivating vegetable seedlings, and basically do not need too much manual management in the later stage.

3. The next step is to cultivate vegetable seedlings, seedlings are the first step, they can be cultivated in sandy soil, and they can be cultivated in other ways.

4. Regarding the culture medium used, it is also a very critical step, we can cultivate it ourselves, of course, we can also buy ready-made ones online.

5. When we choose hydroponic containers, we should choose a relatively large volume, which is conducive to the growth of vegetables. It provides a wide space for vegetables to grow.

6. If the nutrient solution wants to ensure the normal growth of vegetables, it should be replaced regularly, generally about ten days, it can be replaced, of course, depending on the specific vegetables.

Hydroponic planting of vegetables, to prepare a watertight foam box, after the root system of the vegetables is cleaned and disinfected, fixed in the foam board, so that it can be planted in the container hydroponics, in the hydroponic vegetables, to change the water frequently, but also to regularly add nutrient solution to the water, pay attention to the maintenance environment requires warm ventilation.

1. Preparation

If you want to grow vegetables hydroponically, you first need to prepare a suitable container, generally you can use a foam box to hydroponics, the box is required to be watertight, you need to clean it before use, and then you need to prepare a foam board, so that when hydroponic vegetables, it can play a role in fixing vegetables.

2. Hydroponic method

Select vegetables suitable for hydroponics, rinse the soil with water for its roots, and cut off some excess roots, and finally disinfect its roots with a special disinfection solution, dig a small hole in the foam board after processing, and fix the vegetables into it, and the water level in the hydroponic box should just come into contact with the vegetable roots.

3. Change the water regularly

When hydroponizing vegetables, you need to change the water regularly, generally every 5 days or so to replace the best, must not change the water for a long time, otherwise the water quality deteriorates, the vegetables will rot, pay attention to the tap water hydroponics, you must first let the water stand for about 2 days before use.

4. Maintenance management

After the hydroponic vegetables are planted, they need to do a good job in maintenance management, and they should often add nutrient solution to the water every day, so that the vegetables can grow vigorously, and the environment for the maintenance of hydroponic vegetables requires warmth and ventilation, and the vegetables should be exposed to the appropriate light, otherwise the environment is not suitable, and it will also have a negative impact on the growth of hydroponic vegetables.

Planting methods of hydroponic vegetables at home: preparation of containers, vegetable handling, hydroponics, regular water change, and post-maintenance.

1. Prepare the container.

The first thing to do in the cultivation of hydroponic vegetables is to prepare a container, and you can use a foam water tank for home maintenance, which is very convenient. Then put a floating plate of the same size in the middle of the container to carry and fix the vegetables.

2. Vegetable treatment.

Next, the hydroponic vegetables should be treated simply, the roots should be cleaned with water, and then the condition of the roots should be observed, and the old, weak, sick and disabled roots should be cut off and disinfected.

3. Hydroponics.

Add an appropriate amount of water to the container, and add an appropriate amount of nutrient solution to the water to ensure the growth of vegetables. Put the processed vegetables in a container, fix them with a floating plate, and then drill a few small holes in the floating plate to increase its air permeability.

4. Change the water regularly.

When hydroponizing vegetables, you need to change the water regularly, generally every 5 days or so to replace the best, must not change the water for a long time, otherwise the water quality deteriorates, the vegetables will rot, pay attention to the tap water hydroponics, you must first let the water stand for about 2 days before use.

5. Later maintenance.

After the completion of planting, you can carry out normal maintenance, ensure that there is water in the container at all times, need to change the water every 3 4 days, each time the water should be changed to observe the growth of the plant, and at the same time add an appropriate amount of nutrient solution to the water to ensure that the nutrients are sufficient.

When planting hydroponic vegetables, it is necessary to provide them with a well-sealed cultivation plastic box, and it is also necessary to choose vegetables with excellent varieties and health and disease-free vegetables, and then rinse the root system of the plant with clean water, and then the vegetables can be planted in the hydroponic plastic box, and the culture water is replaced every 7-8 days to make the hydroponic vegetables grow vigorously.

1. Provide containers

When planting hydroponic vegetables, in order to choose a container suitable for growth, you can choose a cultivation plastic box with good sealing and suitable space, and then put the plastic box into the water for high-temperature cooking and disinfection, remove the bacteria and germs in the container, and also need to put a floating plate with the same width and length in the hydroponic box to facilitate the carrying of vegetables.

2. Vegetable selection

When planting hydroponic vegetables, you need to choose plants with excellent varieties and then treat them, you can use clean water to clean the soil on the vegetable roots, you also need to use sterilized scissors to cut off the dry and rotten roots of vegetables, and then apply potassium permanganate solution to the fracture of the plant roots for disinfection.

3. Hydroponic method

When cultivating vegetables with water, you need to plant the treated plants in the hydroponic tank, you need to be careful when operating, it is best not to hurt the root system of the vegetables, so as not to reduce the survival rate, and you also need to add a few drops of nutrient solution in the hydroponic tank to provide the nutrients needed for the growth of vegetables and maintain their normal growth.

4. Replace the water

Hydroponic vegetables have higher requirements for water quality, when breeding hydroponic vegetables, if the water quality becomes turbid and black, it will lead to rot of the root system of the plant, so that the vegetables grow poorly, and the culture water needs to be replaced every 7-8 days, and natural water or mineral water that is non-polluting and rich in a variety of nutrients can be used.

Hydroponic vegetable cultivation requires the provision of containers, the selection of plants of good varieties, and the replacement of clean water.

1. Provide containers

When planting hydroponic vegetables, in order to choose a suitable container for growth, you can choose a cultivation plastic box with good sealing and suitable space, and then put the plastic box into the water for high-temperature cooking and disinfection.

2. Vegetable selection

When planting hydroponic vegetables, you need to choose plants with excellent varieties and then treat them, you can use clean water to wash the soil on the vegetable roots, you also need to use sterilized scissors to cut off the dry and rotten roots of vegetables, and then apply potassium permanganate solution to the fracture of the plant roots.

3. Replace the water

Hydroponic vegetables have high requirements for water quality, and when cultivating hydroponic vegetables, it is necessary to replace the culture water every 7-8 days, and no natural water or mineral water can be used.

Hydroponic vegetable production management:

Take pipeline hydroponic vegetable production equipment as an example. The main knowledge of production management is the adjustment of the time and number of nutrient solution supply. The time and frequency of nutrient solution are mainly determined by the cultivation form, vegetable growth state and environmental conditions.

In the cultivation process, the liquid should be supplied in a timely manner to ensure sufficient nutrients**. The liquid supply time is generally selected during the day, and the liquid supply is not supplied at night or the liquid is less.

The number of liquid supply is more on sunny days, and less on rainy days; When the temperature is high and the light is strong, there is more, and vice versa. Under normal circumstances, the liquid is supplied 2-4 times a day, and each time it can be grasped at 30 minutes. This can be adjusted at the right time with a time controller.

1. How to grow vegetables in the early stage of preparing hydroponic vegetables with Zheng You In the process of hydroponics, water is used as the substrate for cultivation, so it is necessary to choose a plastic box that can hold water as a hydroponic vessel, and clean and disinfect it to avoid residual harmful substances, and to put a floating plate into the plastic box to facilitate the fixation of vegetables, so as not to soak the whole plant in water and rot. 2. How to plant hydroponic vegetables with root treatment Before planting hydroponic vegetables, Congyan should take out the vegetables that need hydroponics, clean the roots with water, and then use sterilized scissors to cut off the dead roots and rotten roots of the roots, and then use potassium permanganate dilution solution to soak and disinfect for 30 minutes, and finally rinse the agent with water and hydroponics. 3. Hydroponic method How to grow hydroponic vegetables In the process of hydroponics, water should be injected into the plastic box, and then the processed vegetables should be inserted into the floating plate on the water surface to ensure that the root system is in contact with water, and the leaves are located above the floating plate.
