What are the advantages and disadvantages of hydroponics for vegetables

With the development of science and technology, the soilless cultivation of vegetables has become a trend, and hydroponic vegetables have many obvious advantages compared with traditional soil cultivation. The following is a detailed introduction to the advantages of soilless cultivation of vegetables.

First, it prevents or reduces the obstacles caused by continuous cropping and continuous soils. For some special crops, it can be planted at any height, continuous production, uniform market, and improve land utilization. In the process of management, operations such as farming, weeding, and soil disinfection are omitted, which greatly saves labor.

Because it can meet the needs of crops for temperature, light, water and nutrients to the greatest extent, the vegetables produced are not only high yield and good quality, but also clean, fresh, pollution-free and pollution-free. They are pure green foods that can improve the grade of the product.

Secondly, due to the nutrient solution used.

It can be recycled, and in addition to being absorbed by the roots of vegetables and evaporating naturally, the water consumption is very low, which has the advantage of saving water. At the same time, it promotes agricultural automation. Make full use of and conserve land resources.

The project is a mechanical supporting facilities project, abandoning the traditional soil farming mode, and can save a lot of valuable arable land, labor and water under any conditions, including deserts and factories, cement floors and other environmental construction and production. The automatic circulating water system can save tens of thousands of tons of water resources for the country every year. The project has a combination of automation and mechanical equipment.

All aspects required for growth are completely detached from the traditional model of "facing the loess, facing the sky".

Finally, the soilless cultivation of vegetables greatly reduces the labor intensity. The crops of this project are planted in the air, away from soil bacteria, and the labor links such as spring ploughing, ploughing, weeding, blowing, and sun basking are omitted. For many years, China has been striving for pollution-free green food.

This project is to meet this demand, advocate the direction of development, and create high-quality, high-demand assured vegetables. In addition, it is not affected by geolocation.

Influence of external factors such as soil, continuous cropping, fertilization and climate. It has strong cyclical and continuous tillage performance. The description of "cheap vegetables hurting farmers" truly explains the helplessness of farmers. High production efficiency and economic benefits.

Good, not limited by season and variety.

1. High yield: The yield of vegetables grown in this way is several times or even more than ten times higher than that of traditional soil cultivation or substrate cultivation.

2. Good quality: Because the nutrient solution is used for the planting of vegetables, the nutrient supply is balanced, and the nutrients can be accurately controlled according to the different types and growth stages of vegetables, and they are not easily disturbed and affected by conditions that are not conducive to growth like open field cultivation, so the taste of hydroponic vegetables is better and the internal quality is better.

3. Simple management of facilities and equipment: hydroponic facilities and equipment are planted by pipelines or various planting troughs that can hold nutrient solution, and the equipment is relatively simple.

4. Safe and delicious: hydroponic pollution-free vegetables are natural, no additives, no residual pesticides and synthetic fertilizers, and no hormones.

Disadvantages of vegetable hydroponics: the root system is perishable, if the probability of vegetable root rot increases exponentially in high temperature weather, because the water temperature will be higher when the temperature is higher, and the root system is very perishable when soaked in it for a long time. Hydroponic vegetables can only be maintained by liquid fertilizers, which will consume more nutrients, so that the vegetables are deficient, and these aquatic organisms are more cumbersome to clean up, requiring a large area of water change to keep them basically clean.

The advantage of hydroponics for vegetables is that they grow quickly. The root system of hydroponic vegetables is sprinkled in water, there is no growth resistance, the root system is flourishing, the ability to absorb nutrients is strong, the growth rate of crops exceeds that of soil cultivation, and the pressure of pests and diseases is small. The soil is a hotbed of pests and diseases, and without the soil, the pressure of crop pests and diseases is small, and the amount of pesticides used is reduced.

The disadvantage is that the cost is too high and it is difficult to sell. The cost of hydroponic vegetables is higher than that of soil grown vegetables, and it is also higher. Traditional nutrient solution hydroponics is to mix various chemical fertilizers into water, consumers do not have an extra good impression of this kind of fertilizer vegetables that grow in water, and at the same time, it is higher than soil vegetables, so it is difficult to sell.

The advantage is that it can improve the yield of vegetables, to a certain extent, it can make vegetables fresher, it can play a good role in preservation, and it can provide a very good planting environment. The disadvantage is that it is very water-intensive, and the cost of cultivation is very high.

It can make vegetables taste more delicious, shorten the growth cycle, and extend the storage time, making it easier for the body to absorb.

There are many kinds of vegetables that can be hydroponics, such as taro, garlic, potatoes, cabbage, etc., which are common and have a high survival rate of hydroponics. Taro: Soak the roots in water and change the water the next day.

Garlic: Arrange the garlic neatly, leave a gap, and put it in the water to grow garlic sprouts. Potatoes:

Soak half of the potato in water and it will sprout and sprout.

1. Taro. In addition to soil culture, taro can also be hydroponic. During hydroponics, soak the roots in water and change the water every other day, and it can survive without taking care of it. If you want to eat taro, you can switch from hydroponics to soil culture, and it will grow taro.

Taro. 2. Garlic.

Garlic hydroponics can be cultivated as a single piece or as a whole garlic. Place them in containers with gaps between each one as they will expand after absorbing moisture, and the purpose of leaving a gap is to prevent crowding. At the beginning of growth, there is no need to change the water, only the amount of water added to the initial water level is sufficient.

After changing the water, you should often clean up the green algae on the garlic head, because too much green algae will affect their respiration and affect growth. In about a month, the garlic sprouts will be ripe and ready to be cut and eaten.

Garlic. 3. Potatoes.

The hydroponic method of potatoes is different from the above cultivation methods, it can not put the whole potato into the water when cultivating, only half of it can be put to avoid rotting, it will sprout in about three or four days, and seedlings will grow in a week. During the cultivation period, the water should be changed frequently, and the frequency is once or twice a week.

Potatoes:Fourth, cabbage.

Spread a piece of fresh, undamaged cabbage on top of the table, peel it until only the cabbage heart remains, then flatten the roots and place them in a container filled with water. Put it in a sunny place, change the water every other day, and it will grow roots in about a week.

These nine vegetables can be grown at home and over again. If you grow well, you can be self-sufficient! In addition to saving money, it is more important to be healthy.

I can see and eat, my home is full of greenery, and I am in a good mood

When cooking green onions every day, you can leave green onions about an inch long and attached to the roots, as long as you place it in a glass with a little water and place it in a well-lit room, and you can raise it!

Garlic bought back garlic sprouted, you can just put it in a glass and grow it with a little water. The garlic sprouts themselves have a larger flavor, and the garlic sprouts are lighter, so they will have a good effect when added to salads, pasta, etc.

Cabbage cabbage can also be regrown using a small amount of water with plenty of sunlight. In about 1 to 2 weeks, you will be able to transplant it into the culture soil, and it will slowly turn back into a whole cabbage.

CarrotsRaise the top of the carrot with a small amount of water and place it in a well-lit room or balcony. In this way, you can grow non-toxic and pesticide-free carrots! Great addition to salads.

Basil cut 3 to 4 inches of basil with stems, place it in a water glass, and let it grow and lengthen in direct sunlight. When the roots grow to 2 inches, they can be transplanted into pots and planted.

Celery leaves the celery bottom and places it in a cup or dish with a small amount of water to provide plenty of sunlight. When the middle leaves start to grow, they can be transplanted into the soil.

Lettuce soak the lettuce head in 1 2 inches of water, water daily, and keep the water level at the same height. After a few days, the roots and new leaves have grown and are ready to be transplanted into the soil.

Coriander: Put the coriander stalk in water and it will grow. When the roots grow long enough, they can be planted in pots. Remember to keep plenty of light and you will be able to grow a whole coriander in about a month.

Sweet potato leaves will sprout sweet potatoes, put in water for about seven days to grow a bonsai, can be viewed, hungry and eaten.

Bean sprouts, bean sprouts, and more!

Generally, we choose soybeans, red beans, mung beans, peas (50 grams) with full grains, a drainage basin, a water basin, (** seedling tray for sale) nutrient solution, water.

Method Step by Step Read 1 4

First, soak the beans in a pot with clean water. 2/4

I chose peas, basically the buds will emerge on the 2-3 day, mainly referring to the ambient temperature, generally between 15-35 years of growth is good. 3/4

What you need to do every day is to leave the water filter basin still and change the water in the basin every 2-3 days. 4/4

Bean sprouts grow fast, and they can be cooked in about a week, and we can generally harvest them, and then continue to raise the second crop.

Precautions. Note: Add an appropriate amount of nutrient solution to the water, and you can grow better.

Bean sprouts grow well and eat them quickly, the grown beans need a lot of nutrients to maintain every day, and they will soon turn yellow when they are ripe.

Those who know are coriander, bean sprouts, cabbage, etc.

Braised greens with mizuna, leeks, leeks and so on. There should be a lot of vegetables.

You can grow vegetables hydroponically on your own balcony, and these vegetables are very suitable, so take a look.

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.
