Function of agricultural greenhouse
At present, the main functions of agricultural greenhouses in actual production are as follows:
1. In terms of crop planting and growth
(1) Reduce crop pests and diseases by regulating the temperature and humidity in the agricultural greenhouse, thereby reducing or even eliminating the use of pesticides. In traditional farming, the main reason crops suffer from pests and diseases is due to the temperature and humidity of the open environment. In the greenhouse, the temperature and humidity of the agricultural greenhouse can be properly adjusted according to the type of crops planted, so that the crop growth environment is not conducive to pests and diseases. The breeding of crops can effectively reduce the probability of crop diseases and pests, thus reducing the use of pesticides related to the disinfection of diseases and pests, and achieving the growth of crops without chemical residues.
(2) Adjusting the environment in the shed is conducive to improving crop yield and even accelerating crop maturity. The agricultural greenhouse uses the operation of some control systems to create an environment suitable for crop growth, which can improve and promote the growth, development and metabolism of crops, and reduce the slow growth or insufficient growth quality of crops caused by changes in climate, temperature, precipitation, etc., in the open environment. To a large extent, the phenomenon promotes the accelerated growth and maturity of crops, and can also improve the growth quality, thereby increasing the yield.
(3) Provide a suitable growing environment for regional and seasonal crops, and solve the production and supply problems of regional and seasonal crops. The function of greenhouse environment construction and climate regulation can not only create an environment suitable for the growth and development of crops, but also solve the long-term growth problems of different seasonal crops. Even some crops that are difficult to grow in the open air can be grown normally in the agricultural greenhouse, which makes many out-of-season vegetables appear on our tables, and the quality of crops has been greatly improved.
2. In environmental protection and industrialization
(1) Saving water in agriculture will help alleviate water shortage. As the greenhouse adopts the integrated water and fertilizer watering machine, the whole process of intelligent, timed and quantitative irrigation is realized. Basically, irrigation water can only penetrate into the root development and growth areas of crops, greatly reducing the amount of water used for agricultural irrigation. With the continuous improvement of agricultural greenhouse planting technology and the expansion and promotion of projects, the demand for agricultural irrigation water will be further reduced in the future, which will greatly help alleviate water shortage.
(2) Improve the utilization rate of agricultural fertilizer, reduce the amount of fertilizer applied, activate the soil, and improve the soil quality. On the one hand, the water fertilizer machine is widely used in the agricultural greenhouse for irrigation, which can directly transport fertilizer and water evenly to the plant roots, not only improving the utilization rate of fertilizer, but also reducing the amount of fertilizer used. On the other hand, smart irrigation can not only reduce soil compaction caused by flood irrigation and uneven fertilization, but also make the soil on the field more permeable, thereby improving soil quality.
(3) To better meet the global human demand for crops and improve the quality of crops. For a long time, our crop production and consumption regions have had problems with cross-regional deployment. The deployment process not only increases the price of crop products, but also often leads to a reduction in supply due to the long deployment time. The emergence of agricultural greenhouse cultivation has solved the above problems well, and it can also produce non-polluting vegetables and fruits in the off-season to further meet the consumption needs of different groups of people.
(4) Faster and better promotion of the application of advanced technology in agriculture will greatly promote the development of modern agriculture. Greenhouse is not only an intensive industry, but also a high-tech industry. Advanced technology can not only effectively use natural energy, but also continuously promote the development of cultivation, water saving, formulation, standardization and other technologies, which is of great significance to the development of advanced modern agriculture. Promotional effect.
(5) Reduce the investment risk of agriculture and planting industry, and promote the industrialization of agriculture and planting industry. Greenhouse effectively avoids the profound impact of climate, environment and natural disasters on agriculture and planting industry, and is of great help to the continuous development and growth of agriculture and planting industry.
All in all, the application and promotion of greenhouses can solve our supply and demand problems for crops, and it is also of great help to save water and energy. It not only satisfies people's needs, but also protects the environment.
