Rural planting technology: key points of hydroponic culture technology!

Most of the planting industry in China is traditional planting industry, how to change it to modern planting industry? At this point, we can learn from developed countries in Europe and the United States to promote hydroponic culture technology, which is a kind of soilless cultivation technology, which originated in Israel. The main technical feature is to use nutrient solution instead of soil for plant cultivation.

Introduction of hydroponic culture technology

Hydroponics technology originated from some developed western countries, and essential changes have taken place when hydroponics technology was introduced into China. For the sake of profit, some Chinese businessmen directly put the washed plants into the water to save costs without artificial cultivation and bioengineering, so that the plants did not seem to die at that time, but a few days later the leaves of hydroponic plants began to turn yellow. finally, the hydroponic plants die slowly. This is not only irresponsible to customers, but also harmful to the real hydroponics industry. The real hydroponic plant is to put the plant in the nutrient solution, which is prepared by professional hydroponic technology. Plants are cultivated artificially or nurtured, with a survival rate of more than 95%. If you add professional care in the later stage, it can be said that they will not die. Some fake hydroponics not only hurt themselves, but also tarnished the real hydroponics technology.

Hydroponic technology is a very professional technology, which requires careful and serious people to do this industry. Businesses who do not know the professional skills are not willing to train their own skills, and many businesses do not have that kind of awareness and patience.

Advantages of hydroponic culture technology

1. Hydroponic things grow fast

Because plants are soaked in nutrient solution (chemical fertilizer), it is impossible to grow slowly. Only by growing fast can we make full use of the limited space, achieve the high output of "balcony agriculture" and achieve the goal of self-sufficiency.

2. Reduce soil diseases

China already has a large population and little land, and planting in the field is often repeated. If planted on the urban balcony, 100% of the ordinary vegetable garden soil will have diseases and insect pests, unless a special cultivated soil rich in organic matter is used, and the water will be changed after hydroponic culture and planting. The effect of changing the soil is better than the rotation in the field, and the effect of preventing serious stubble is better than the rotation in the field.

3. Clean

Even if the hydroponic container is turned over, the mop will be clean, while the soil, the flowerpot turned over, watering leakage, overflow, will make the ground very dirty and pollute the balcony environment.

4. Convenient management

There are no complicated procedures such as weeding, spraying and loosening soil in field cultivation, and the management is simple.

The disadvantage of hydroponic culture technology

1. The technology is tedious (note: not complicated)

Understand the basic theory, comprehensive application of other knowledge, hydroponic vegetables is not difficult, but there are a lot of details need to be carefully dealt with. There are many things to be done in the aspects of water, fertilizer, temperature, light, qi, disease and insects, as well as the stages of planting, seedling, flower and fruit.

2. It is difficult to get started at first, which affects confidence.

Because it is tedious, you will encounter a lot of difficulties at the beginning. If you have no confidence, you are likely to give up. In the end, I can't feel the joy of a bumper harvest.

3. More investment at the initial stage

Water culture devices that can reach a practical level should be paid attention to in all aspects, so it is often a set of equipment or materials, and the initial investment is much more than that of potted plants that only need a little soil, a flowerpot or other containers. It's easy to be intimidating. In fact, as long as you can start, a lot of materials are available in life, except for the necessary outsourced equipment, most of them can be DIY, and these devices can be used for a long time, generally speaking, the cost is not high, or cost-effective.

4. there is a gap between complete organic food and organic food.

Hydroponic vegetables, if not controlled, will lead to excessive nitrate and nitrite. Therefore, it is necessary to apply frequently and less, and replace a new nutrient solution for each crop. There is still a gap between the standards of hydroponic vegetables and organic food. But now the things grown in the field, excessive application of chemical fertilizers and even organic fertilizers, may also lead to excessive nitrate and nitrite, and there will certainly be the problem of pesticide residues. In the process of trafficking, the water sprayed by hawkers will inevitably be contaminated by bacteria.

Attached: garlic hydroponic culture method

1. Take garlic, you can peel off garlic cloves and put them in a container (suitable for smaller containers). You can also peel off the outermost skin of garlic, directly expose the garlic cloves, and put them in a container (which can be put in a larger container)!

2. Add water directly and soak the bottom of the garlic. This is good for rooting!

3. Usually change the water every 1 to 2 days to keep the water fresh! In the initial stage, the water can not be changed for 3 days in a row to facilitate the fixation! After rooting is fixed, the frequency of changing water can be more frequent!

4. After general hydroponic culture, it can take root on the same day, and green can be seen after 2-4 days.

5. Harvest: generally, 2-3 stubble can be harvested continuously, the first few stubble can only take more than the part of garlic cloves (white stem), the last stubble can be harvested directly through root, and the last harvest standard: when the nutrition of garlic cloves in water is completely exhausted! As long as the season is right, you can proceed to the next round of garlic hydroponics, the method is the same as above! Generally from October to the Spring Festival of the following year, you can continue hydroponic training for 3-4 rounds, each of which can last for 40-50 days, ensuring that you can continuously enjoy the green garlic seedlings from late autumn to early spring!
