What are the key considerations for building a "modern agricultural greenhouse using integrated water and fertilizer technology"?

Although China's facility agriculture greenhouses have been developed for decades, many agricultural growers and those interested in agriculture still adhere to the traditional Shuguang earthen-wall greenhouse model. Modern agricultural greenhouses are far more diverse than their predecessors. They play a crucial role in the modernization of rural agriculture. With the increasing number of modern agricultural parks and family farms nationwide, the application of greenhouses is expanding, leading to more questions about building modern agricultural greenhouses. Many ask what precautions are necessary when building a modern agricultural greenhouse. To address this, we consulted with water-fertilizer integration experts, who provided the following three suggestions. First, broadly speaking, modern greenhouses represent an electromechanical and intelligent upgrade of traditional vegetable greenhouses, focusing on efficiency and resource conservation. The significance of greenhouses extends far beyond simple cultivation. Currently, greenhouse-based creative experiences are flourishing worldwide; therefore, the future development potential of greenhouses is enormous, representing a promising technology. Regarding key considerations for modern agricultural greenhouses, the first is site selection. Construction site selection is highly dependent on regional suitability and is largely constrained by local climatic conditions, including solar radiation, winter temperatures, summer temperatures, summer relative humidity, and wind pressure. Second, it's crucial to adapt to local conditions. It's recommended that professional designers create the plans, which are then reviewed, revised, and finalized by local farmers, especially those with greenhouse cultivation experience. Environmental factors must also be considered. Suitable land for agricultural facilities is limited; therefore, choose flat, sheltered, sunny locations with convenient transportation, good water sources, and readily available electricity. During construction, pay attention to lighting, temperature control, water supply, humidity control, and ventilation. Consider incorporating vertical cultivation and soilless planting to maximize space utilization. Second, since these are modern greenhouses, in addition to traditional natural conditions, efforts must be made in technology and equipment. This includes computer-based monitoring and digital analysis systems. While the technology may seem advanced, it enables semi-automation, freeing up labor and saving water, fertilizer, electricity, and energy. Sensors for monitoring photosynthetic rates, soil composition, and specific diseases and pests are becoming increasingly sensitive and efficient. Third, when selecting greenhouse building materials, choose construction methods and materials based on your capabilities. The most crucial aspect is greenhouse insulation; only with good insulation can you achieve good returns. The greenhouse covering material must allow solar radiation to pass through while maintaining sufficient durability. Polytetrafluoroethylene (PTFE) is currently widely used. Finally, Yuncheng Yuanfeng Water-saving also suggests that the construction of greenhouses in cold regions should utilize natural resources as much as possible, locating them near pollution-free areas with excess heat (such as near power plants). In agriculture, it's essential to consider the unique local microclimate, production conditions, and production habits. Carefully explore, observe, and understand these patterns. Impulsive decisions often lead to significant losses. Successful agriculture can be incredibly rewarding; however, entering the industry without a plan or foresight is akin to 'shooting oneself in the foot'!
