Vegetables are an essential ingredient on the table. Common vegetables are planted with open fields and potted plants. However, in recent years, it has been popular for the cultivation of soilless vegetables. I believe that most of them are not very familiar with this. Let's take a look at the key points of soilless vegetable cultivation techniques.
First, the concept of soilless vegetable cultivation
Soilless cultivation is the use of nutrient substrate or nutrient solution to replace the soil as the root growth environment required for plant growth, and a planting mode for crop cultivation. Nutritional matrix components: perlite, vermiculite, peat, cocoon and other substances. Nutrient solution: A crop culture liquid with nutrient elements.
Second, the advantages of soilless vegetable cultivation
1, don't worry about nutrient loss
The nutrient base or nutrient solution can provide the nutrients needed for the growth of the crop (when planting different kinds of crops, different matrices should be formulated because the matrices are formulated according to the nutrients required for crop growth). In other words, the nutrients absorbed by the crop will not decrease, and the nutrients contained in the crop will not decrease. Therefore, there is no need to worry about the loss of nutrients in soilless crops.
2, the number of pesticide application is reduced
Soilless culture is a newly prepared substrate, so there is no continuous cropping obstacle and soil-borne disease, which means that the incidence of soilless culture crops will be greatly reduced, so the number of pesticide application will be much lower. At the same time, because the nutrients required by the crop are contained in the matrix, it will also reduce the use of fertilizer! It is safer and more reliable than the vegetables grown in the soil.
In fact, soilless vegetables are a good development project, but the reason why there is no large-scale production is because the cost of soilless cultivation is relatively high, and it is not suitable for large-area application production. I believe that with the continuous development of technology, soilless cultivation Will become the mainstream. Everyone can eat soilless vegetables, or cultivate them without soil.
