Độc đáo mô hình trồng rau không cần đất

Hello everyone, you are now watching the show on VTG 16 agricultural TV channel. Dear everyone, no need for land, the vegetables grown in this large area are still growing very well. Only after 15 days, from when the seeds are harvested, the vegetables can be harvested. Not only that, the yield of vegetables has increased from 25% to 40% compared to those grown in the field. In 4 seasons, this area can grow vegetables. These are the differences that this hydroponics model brings to Mr. Nguyen Van Tuan in Ngo Quyen, Bac Giang province, Bac Giang province. To learn more about this model, please follow the interview right after this. Water spinach, green cabbage, lettuce, Japanese mustard. All of them grow on plastic pipes. There is no land, but we can see that the vegetables here live very well. This is my secret. This is a solution to grow water spinach. This vegetable garden is grown by Mr. Tuan according to the water spinach method. According to this method, the seeds are harvested and the vegetables are grown without land at all. With this method, Mr. Tuan has increased the yield of vegetables by 20% to 50% compared to traditional methods. In particular, he can grow vegetables all year round. So, what is his secret? The vegetables will be grown directly by Mr. Tuan in the clean water system. And the nutrients have been tested by the state authorities to determine the quality. No heavy metals or other toxins are left. Each type of tree will have a different method of growing water spinach. However, according to Mr. Tuan, the best growth rate of water spinach is from 1,000 to 1,300 per thousand. Normally, the cost of a set of water spinach is between 100,000 and 1,000 VND per set. That is 1 liter of water. With 1 liter of water, we can grow more than 300 tons of water. With the same family size, we can grow 10 square meters. It takes about 3 months to replace a set of water spinach. Now, there are two ways to grow water spinach. They are frozen water spinach, also known as Hoi Luu water spinach and Tinh water spinach. Mr. Tuan has chosen to grow water spinach. Hoi Luu is an automated system. It uses a continuous water pumping system to supply nutrients to the tree on schedule. The advantage of this method compared to Tinh water spinach is that it does not need an oxygen pump. But the roots of the vegetables are still fully nourished. In particular, Mr. Tuan also studied and gave birth to his own product for water spinach. Since then, the water in the tube is no longer stagnant, no bacteria are formed, and it is easier to regenerate. Therefore, the vegetables in Mr. Tuan's garden have a 100% survival rate. Compared to growing vegetables on the ground, water spinach harvests earlier than 10 to 15 days, depending on the type of vegetables. The vegetables we are growing here can also be grown in the garden. The water spinach solution ensures that the vegetables in the garden do not get sick. Secondly, if it is sunny in this season, we use a solar system to keep the vegetables from getting hot and dead. It is difficult to grow, so we use a system that spreads out to make the vegetables cooler. This is a high-tech vegetable growing model. It is very environmentally friendly and effective. Using this technology will help vegetables in Vietnam export more efficiently in the future. Without using soil, Mr. Tuan does not have to spend a lot of time growing vegetables. Although the area to grow vegetables is nearly 1,000 square meters, Mr. Tuan only needs two workers. In particular, compared to the traditional way of growing vegetables, the vegetables are grown in nests, so they are restricted from getting sick. Mr. Tuan does not have to use any pesticides at all. Why do you think you will grow water spinach? We have been growing water spinach for about two years now. This solution is suitable for vegetable growing families. In terms of the cost of vegetables, this product is about 50% higher than growing vegetables on the ground. But it brings back the clean vegetables for consumers. On average, every year, Mr. Tuan sells about 4.5 tons of vegetables for the Thien An supermarket chain and the 24-hour store system in Bac Giang and nearby provinces. In addition, to ensure a clean supply of vegetables according to the market demand, Mr. Tuan also connects with many other farmers in Quang Ninh and Hanoi provinces to transfer technology as well as export products to them. Water spinach is sold on the market from 30,000 to 40,000 VND per kilogram, which is 6 to 5 times more expensive than water spinach. But many people still use water spinach. Water spinach is still very new compared to people in Hanoi. Therefore, the number of customers who use water spinach is not much. But most of the people who use water spinach come back and continue to use this product. First of all, the taste is very good. Then gradually there is a belief. And the belief comes from the reputation and quality of the product. I often eat vegetables. So the feeling of eating vegetables here is very delicious and crunchy. Both technology transfer and export of vegetables. On average, Mr. Tuan earns about 5 billion VND per year. According to Mr. Tuan, this model has quite a wide range of applications in all provinces of the country. Materials such as soap boxes and plastic boxes are available on the Vietnamese market. Water spinach can be used in areas that are not suitable for planting, but can still produce high-quality products. Water spinach is a technique for planting vegetables without using soil. Planted directly in a nutritious or cost-effective environment. And the secret of this technique is to supply enough and at the right time for the plant the necessary minerals to ensure enough light. Therefore, in the next part of the program, Mr. Nguyen Van Tuan in Bac Giang, who has successfully grown vegetables for many years, will share with the people some tips when growing water spinach to achieve the best results. Light is the most important factor for the development and growth of vegetables. Sunlight is the only source of energy to create light, turn inorganic materials, water and carbon dioxide, turn inorganic materials in leaves, flowers, fruits and vegetables. Different types of vegetables have different needs for light. Therefore, according to Mr. Tuan, people who grow water spinach need to understand this in order to properly grow vegetables and create the right light for the best development of vegetables. When serving households, we must pay attention to whether there is enough sunlight on our shelves. Normally, in the shelves of the family, the sunlight is not enough. To grow vegetables with water spinach or soil, the sunlight must ensure at least 5-6 hours a day to shine into our vegetables for them to grow. If the sunlight is weak, we can add a LED system. If the sunlight is not enough, the vegetables will grow in high places, and the trees will be very thin. This will not ensure the best yield, and the vegetables will not be healthy, and the quality of the vegetables will be poor. Direct sunlight into the water spinach system can increase the temperature. Trees are prone to drought. It can also change the pH concentration in the soil. Therefore, if you grow water spinach outdoors, you should use a black net to cut the sunlight. The black net can both reduce the intensity and expand the light, helping the plant to grow well without affecting health and development. In addition, water spinach is a short-lived plant, but has a large yield, so it needs to be supplied with sufficient nutrients. Therefore, according to Mr. Tuan, people need to regularly check the nutrient concentration to ensure the necessary amount of nutrients for the plant. There are two main types. One is a type of water spinach for eating leaves, the other is a type of water spinach for fruit. The composition and content of water spinach and water spinach are different. With water spinach, the plant grows from 1,000 to 1,300 mm. But for the fruit tree, depending on the type of tree, and depending on the time when the tree grows, we mix the nutrients differently. Mr. Tuan also said that if the roots of the tree are deep in the nutrients, they will lack oxygen due to the nutrients preventing the transfer of nutrients and gases. Therefore, only 1-2 cm of the root of the plant should be submerged in water spinach. In addition, Mr. Tuan also noted that water spinach nutrients need to be mixed at a certain rate. With the young tree, which has just been planted, the nutrient concentration is 600-900 ppm. After a week of growing, the nutrient concentration is adjusted from 1,000 to 1,300 ppm. An important factor in growing water spinach is the price. This is the base for the roots. From here, the roots will grow out to find water and nutrients for the growth and development of the tree. Therefore, the price of water spinach must be fresh and clean. To ensure that water spinach does not get sick, before planting, we mix the nutrients with biological products. We mix all the nutrients together before putting them in the water spinach system. In addition, Mr. Tuan advises those who plant vegetables to regularly, from 3 to 5 days, use a pesticide-free method such as 1 kg of garlic plus 1 kg of chili, 1 kg of ginger and 1 liter of white wine. Mix after grinding so that it is soaked for 10 days. Then, apply the mixture to the leaf by 200 ml of pesticide-free solution with 5 liters of clean water. Or you can mix the pesticide-free solution from leafy parts of the plant to treat the root, root, leaf, stem, onion, spinach, white powder, and eucalyptus. If the garden is automatically installed in a curtain, for all the vegetables in the garden.
