The development of ecological civilization and the enhancement of individuals' living standards have prompted a greater level of concern among individuals regarding food safety, thus elevating the requirements for agricultural production.
In the process of modern agricultural vegetable cultivation, greenhouse technology as well as scale management is one of the key points.
Vegetable cultivation requires high requirements for temperature and light and requires better management and pest control during cultivation, thus also putting higher demands on cultivation techniques.
In this day and age, the ability to eat fresh vegetables in every season depends on the development and promotion of greenhouse technology in modern agriculture.
Greenhouse technology is widely used for vegetable cultivation, but also for the cultivation of fruits with high light and temperature requirements, such as cherries and grapes.
In the modern agricultural environment, the application of greenhouse technology has also formed a village community-based collection management model, which realizes the large-scale management of vegetable cultivation.
The application of greenhouse technology has largely circumvented the influence of natural conditions on vegetable cultivation. First of all, through temperature regulation in the greenhouse, high and low-temperature injuries in the vegetable cultivation process can be effectively avoided.
Secondly, the light transmission of the plastic greenhouse is better, and there is a light source inside the greenhouse, which also meets the demand for light for vegetable growth. Finally, the ventilation performance of greenhouses is better, and can meet the needs of vegetable cultivation and growth in all aspects.
With the development of modern agriculture, the supporting infrastructure construction of greenhouse technology is also gradually improved. Under the support of modern agriculture and temperature greenhouse vegetable cultivation technology, the quality and safety of vegetables have been improved and guaranteed.
Modern agricultural vegetable cultivation should pay attention to the following points.
1. Temperature control points
For temperature control, the greenhouse cover and the choice of film are the focus. First of all, you should choose heat insulation and moisture reduction plastic arch film, this type of film insulation effect is better.
Then the specific covering process can be used in the way of multi-layer covering, which can play a good insulation effect in winter.
This is the insulation control measures used for winter low temperature, in the spring also need to adjust the temperature and humidity in the greenhouse, to avoid the occurrence of high temperature hazards.
2. Light control points
Light is an important condition for the photosynthesis of vegetables, but also the necessary conditions for their accumulation of nutrients and growth. Therefore, in the process of greenhouse vegetable cultivation, need to do a good job of light control in the greenhouse.
Greenhouses need to cover multiple layers of film, so the light received by vegetables in the greenhouse is only about 50%-70% of that received by vegetables in the open air. Therefore, strengthening the light control for greenhouse vegetable cultivation is very important and necessary.
3. Ventilation control points
The use of greenhouse cultivation vegetables, but also need to pay attention to the ventilation control of the greenhouse.
Ventilation serves as a critical method for both cooling and reducing humidity within a greenhouse, thereby protecting the vegetables inside from the adverse effects of elevated temperatures. This process ensures a more controlled environment, conducive to healthy plant growth and development by mitigating heat stress and preventing moisture-related issues such as mold and mildew. Implementing effective ventilation strategies is essential for maintaining optimal conditions for vegetable cultivation in greenhouse settings.
At the same time, ventilation can also promote the air circulation inside the greenhouse, which can effectively eliminate harmful gases and reduce the occurrence and spread of vegetable pests and diseases.
In the ventilation control, usually in the wind shelter one or more vents, in the management process also need to pay attention to the changes in the location of the vents to ensure that the entire greenhouse ventilation condition is good.
To sum up, the birth and development of modern agricultural vegetable cultivation technology has largely improved the efficiency and quality of vegetable cultivation, which also well meets the current demand for green vegetables and pollution-free products qualities.
With the development of Internet + agriculture and the application of information technology in agricultural production, modern agricultural vegetable cultivation technology will develop in the direction of big data management and remote management.
