In the past, vegetables were often stored or pickled in northern winter to prolong the edible period of winter vegetables. However, fresh vegetables stored and pickled for a long time, especially leafy vegetables, will not only cause the loss of original nutrients, but also increase the content of nitrate and nitrite in vegetables, affecting human health. The emergence of new planting technology can make up for the lack of nutrients brought by a single vegetable variety in winter and spring, and play an important role in the rational diet.
Hydroponic cultivation is the most popular technology in new agriculture. Hydroponic cultivation is not only suitable for large-scale planting, but also suitable for small-scale family planting. Nowadays, young people prefer to pursue excitement. Some people are also very interested in growing vegetables and want to experience the joy of growing crops slowly. However, living in the crowded environment of the city, there is no one mu of land for people to display. The hydroponic cultivation technology, which is simple and does not occupy a lot of space, has been favored by everyone.
Hydroponic culture is one of soilless culture techniques. It uses nutrient solution to replace soil for plant cultivation, and hydroponics technology is widely used in the production of vegetables, fruits and flowers in developed countries such as Europe, America and Japan. At the beginning of hydroponic planting, the first thing we need to do is to select hydroponic system. There are many hydroponic systems we can choose from, such as hydroponic tower system, nft system and aeroponic system. We can choose suitable planting system according to our own needs.
Hydroponic tower system is very popular in family planting. This is not only because of its beautiful appearance, but also because all kinds of leafy vegetables can be planted, such as lettuce, spinach and other household common vegetables. In addition, the operation of the hydroponic tower system is relatively simple. We just need to plug in the power supply and make the column system power on and water on.
The characteristic of hydroponic vegetables is to irrigate crops with nutrient solution embedded in clean water through flowing water technology, so that vegetables can grow in a clean environment without spraying medicine or chemical fertilizer. The hydroponic vegetables grown in this way are more green and safe.Hydroponic cultivation has many advantages, of which the high quality of crops is a significant advantage.
The environment of hydroponic vegetables is relatively controllable, so the yield and quality of hydroponic vegetables are far higher than those of traditional soil cultivation.The hydroponic vegetables are cultivated and planted with nutrient solution, and the nutrient supply is relatively balanced, and the nutrient supply can be controlled according to different stages. Because of getting rid of the restriction of traditional soil planting, it is not easy to be affected by insect bites and drought, which directly affects the taste of vegetables and the quality is better.
With the improvement of living standards, the quality of life people pursue is also rising. Food, as an essential thing for human survival, was first valued by people. Now people's pursuit of food is also higher and higher. How to improve the quality of food is a problem we need to solve urgently. Vegetables and fruits, which are rich in many nutrients, are the focus of people's attention. The new planting technology should pay more attention to how to improve product quality.
