,Vegetable greenhouses are one of the types of greenhouse planting. As the name suggests, they are mainly used to grow vegetables, artificially create a suitable ecological environment, supply different vegetables regardless of seasons according to market demand, and break through the traditional concept of relying on the sky. Human beings have the initiative to control their own diet.
The vigorous development of vegetable greenhouses has met the needs of the market and people in a standardized manner. However, not all greenhouse vegetables can increase production and increase, and losses due to poor management and management abound.
With the progress of the times, the development of science and technology, and the improvement of living standards, people's material needs and quality have increased significantly. However, with the increasingly serious environmental pollution and the rising population, we have to calm down and think:
Influencing factors of vegetable greenhouses:
(1) Vegetables are also plants, and photosynthesis is required for plants. Different varieties of vegetables have different requirements for light, and vegetables have different requirements for light at different growth stages. There is no sufficient light environment, plant lights do not have a reasonable light ratio, daylight and artificial plant lights do not have a good combination of supplementary light, which is one of the main reasons why the yield and quality of greenhouse vegetables cannot be improved.
(2) Unreasonable vegetable varieties and planting structures in greenhouses are also an important factor causing losses. Different vegetable varieties have different market demands. Some varieties lack competitiveness and have no market potential; more importantly, different vegetables have light demand. They are also different, and it is inevitable that these factors can cause losses if they are not well controlled.
(3) The air circulation obstacle in the shed is another factor that causes losses. The lack of air circulation will lead to inappropriate temperature in the shed, too high concentration of harmful gases, too high carbon dioxide concentration, etc., not only the vegetables cannot grow normally, but it will inhibit the growth of plants. Or cause plants to wither and die.
