Hydroponic cultivation has become a daily routine, which vegetables are suitable for hydroponic cult

There are many kinds of vegetables suitable for hydroponics, the more common ones are leeks, lettuce, green onions, bok choy, coriander, lettuce, celery, etc. If tap water is used in hydroponic vegetables, it should be dried before use.

Common hydroponic vegetables are: potatoes, garlic, taro, cabbage, lettuce, spinach, tomatoes, peppers, cucumbers, celery, cress, watercress, pear...

Lettuce and spinach are actually suitable for hydroponic planting, and they can also make it grow more robust and more nutritious and healthy.

Hydroponic vegetable cultivation refers to a way of growing vegetables using water and fertilizer, which is the most advanced cultivation method today, which can effectively improve the yield and quality of crops. Once you've prepared your water, fertilizer, and seeds, it's time to start growing vegetables hydroponically:

1. Preparations.

1.Prepare the bucket: In order to control the water temperature, it is best to heat the bucket before planting and control the amount of water in the bucket to 15-20 cm, so that the vegetables can swim freely;

2.Prepare fertilizer: water supply, nutrient input, organic nutrients and inorganic fertilizers can be used, and should be stirred in advance before input;

3.Prepare seeds: Cultivate seeds into barrels, and require the quality of seeds to be healthy to ensure the survival rate;

2. Grow vegetables.

1.Water quality control: Once the seeds are planted, the quality of the water should be checked regularly and tested with a water quality analyzer;

2.Ventilation: During the cultivation process, attention should be paid to controlling the amount of ventilation to ensure the stability of temperature and humidity control;

3.Control plant conduction: During the cultivation process, it is necessary to control plant conduction, adjust the water temperature and water quality of Beihu to ensure the normal activities of vegetables;

4.Fertilizer management: Fertilization should be planned, and fertilizer supply should be carried out regularly to ensure that the cultivated vegetables are nutritious;

5.Pesticide management: prevent the occurrence of pests and diseases, timely application of pesticides at all growth stages, and maintain the surface quality of vegetables;

6.Water control: During the cultivation process, attention should be paid to water control, which not only has an important impact on the absorption and release of organic nutrients, but also can alleviate the obvious changes in soil drainage capacity.

3. Harvest vegetables.

When harvesting, you should pay attention to the color of the vegetable leaves, when the color is getting lighter and lighter, you can harvest, and after harvesting, you can wash it and eat it.

In general, the key to hydroponic planting of vegetables is to control water temperature and water quality, do a good job in water and fertilizer management, timely application of pesticides, and reasonable control of harvest time, so as to obtain higher yield and quality of vegetables.

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.

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.

The hydroponic vegetable cultivation method is as follows:

1. Make a hydroponic box.

Before planting hydroponic vegetables, you should prepare a watertight hydroponic box, it is recommended that you use plastic foam boxes, and place a floating board of the same size on the box, the purpose is to carry vegetables.

2. Handle vegetables.

Before hydroponic planting, the vegetables should be treated simply, the hydroponic vegetables should be selected first, the roots should be rinsed with clean water, and then its roots should be combed, and its dead old roots and rotten roots should be cut off with scissors, and then potassium permanganate should be used to eliminate them.

3. Hydroponics.

Be careful when planting, do not hurt its roots, it is best to add an appropriate amount of nutrient solution to the hydroponic box, the root system of the seedlings is planted, and there should always be water in the hydroponic box.

Fourth, planting and maintenance.

Pay attention to changing the water after planting, because there will be a lot of bacteria in the water during hydroponics, and the water quality will deteriorate over time, so you should pay attention to changing the water, you can use rainwater, water in the pond, or water from the river.

5. Sterilization. The solution in the pool should be disinfected, and chlorobromoisocyanuric acid can be used for sterilization, or fungicides in the fish farming industry, but it should be noted that the chemicals used can not hurt the roots, and the diseases can be controlled by foliar spraying fungicides, such as mesomycin, mainly for the prevention and control of bacterial diseases.

1. Make a hydroponic box.

Before growing hydroponic vegetables, it is necessary to prepare a watertight hydroponic box, and it is recommended that you use plastic foam boxes. A float of the same size is placed on top of the box to carry the vegetables.

2. Handle vegetables.

Before hydroponic planting, the vegetables should be treated simply, and the hydroponic vegetables should be selected first, and the roots should be rinsed with clean water. Then comb its roots, cut off its dead roots and rotten roots with scissors, and then disinfect it with potassium permanganate. The disinfected root system should not be directly hydroponic, but should be rinsed with clean water before colonization.

3. Hydroponics.

Be careful not to damage its roots when planting, and it is best to add the right amount of nutrient solution to the hydroponic box. The root system of the seedlings should be planted well, and there should be water in the hydroponic tank at all times.

Fourth, planting and maintenance.

Pay attention to changing the water after planting, because there will be a lot of bacteria in the water during hydroponics, and the water quality will deteriorate over time. Therefore, it is necessary to pay attention to the water exchange, which can be used from rainwater, water from ponds, or water from rivers.

Hydroponic vegetable precautions

1. The environment of hydroponic vegetables should be kept warm and moist all year round, the temperature is between 10 and 25 degrees, and the minimum should be kept above 5 degrees, and the potted plants should be placed in a cool place after the temperature is higher than 30 degrees, so as to avoid excessive temperature, and if necessary, you can sprinkle water around to cool down.

2. It is not advisable to give too much light to the maintenance of hydroponic vegetables, the irradiation of light is easy to make the container or the root system of vegetables grow green algae, after the green algae wraps the root system or container, it will affect the root respiration of vegetables, easy to cause rotten roots, green algae rot regret emitting odor.

Hydroponic vegetable planting methods: preliminary preparation, root treatment, hydroponic methods.

1. Preliminary preparation: In the process of hydroponics, vegetables use water as the substrate, 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 to avoid the whole plant being soaked in water and rotting.

2. Root treatment: Before hydroponic vegetables, 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: 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, so that the leaves can be envied above the floating board.

Advantages and disadvantages of hydroponic vegetables

High yield: The yield of hydroponic vegetables is several times or even more than ten times higher than that of traditional soil cultivation or substrate cultivation. Good quality:

Because it is grown with nutrient solution, the nutrient supply is balanced, so the taste is better and the quality is better. Safe and delicious: Green vegetables cultivated with nutrient solution can reach grade A, and those cultivated with organic fertilizer can reach grade AA level.

Disadvantages: Generally, hydroponic vegetables are lighter in color, the stalks are longer, they look unenergetic, hydroponics and light can not be carried out at the same time, and strong light will increase the water temperature, or it will have to reduce the light, which makes the plant lack photosynthesis.

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.

1. Root treatment

For the best planting of hydroponic vegetables, generally speaking, it is best to clean the roots of the selected plants with water, and then disinfect them with a small amount of potassium permanganate solution, and then cut off the fibrous roots, dead roots, and excess lateral roots on the old roots to promote the growth of new roots.

2. Equipped with hydroponic box.

It is best to choose an impermeable box for hydroponic vegetable containers, generally common potted shrubs or wooden boxes, with Styrofoam boxes are the best, and then inlaid with different foam plastic floating plates to load vegetable seedlings, and then fix the floating plates.

3. Make nutrient solution.

The most important thing for hydroponic vegetables is the vegetative growth of vegetables, so to ensure the quality of the nutrient solution, 1 gram of magnesium sulfate, 1 gram of potassium nitrate, 3 grams of potassium dihydrogen phosphate, 5 grams of urea, 1 gram of calcium sulfate, and 8 grams of zinc sulfate are added to dissolve the best.

4. Planting and sowing.

Then the seedlings are placed in a mixed liquid substrate filled with grass charcoal and washed slag, the roots are put into it, and then 4 or 5 small holes are made on the floating plate to facilitate air circulation to promote the growth of the plants, and then an appropriate amount of nutrient solution is added to the substrate, and it is best to place it in a ventilated environment.
