PACKAGING & SHIPPING
1.How many years can plastic films last? At least 15 years
2.Hot-dip galvanized skeleton can be used for how many years? At least 25 years
3. What is the function of outside shading system. External shading is a physical way to block solar radiation heat and sunlight from entering the interior through building envelopes. Heat transfer modes include heat conduction, heat convection and heat radiation. Since the energy transfer of solar radiation is mainly thermal radiation, we focus on the impact of thermal radiation on indoor environment.
4.What will happen if the distance between greenhouses is too small? The distance between the two greenhouses is too small, which will lead to the shading effect between the greenhouses, which is not conducive to the growth of some shaded vegetables and lead to the reduction of vegetable yield. In addition, if the distance between the two greenhouses is too small, snow in winter will lead to no more snow. In addition, the rainy season in summer results in more water accumulation. However, the distance between the two shelters is too large, which will lead to the weakening of the windproof effect.
5.How to build an intelligent greenhouse environmental monitoring system for the newly built flower planting greenhouse? Intelligent environmental greenhouse monitoring system is based on real-time plant growth environment information obtained by wireless network. For example, through various types of sensors, soil moisture, soil temperature, air temperature, air humidity, light intensity, plant nutrient content and other parameters can be monitored.
6.Normally, how to arrange monitoring equipment for intelligent monitoring system of greenhouse? It depends on the size of the project. Each greenhouse greenhouse should be equipped with several cameras to ensure that the whole scene of the ROC can be seen.
7. What are the components of intelligent greenhouse environmental monitoring system? Intelligent greenhouse environmental monitoring system, also known as greenhouse intelligent system, its components include the perception layer (including temperature sensors, humidity sensors, etc.), transmission layer (data transmission), application layer (control management).
8.What are the benefits of using intelligent greenhouse system in greenhouse for flower planting? This will help you save manpower and material resources. After all, there is no need to care so much about intellectualization, and no need to worry about changes in the environment at any time. 5.What are the main indicators of greenhouse cultivation in agriculture? Agricultural greenhouse cultivation mainly detects four indicators, including temperature, humidity, soil moisture, carbon dioxide, light and so on.
9.Greenhouse greenhouse can play a role of heat preservation and moisturization, to create a better growth environment for crops, but if the humidity is too heavy, it is also harmful to crops, how to reduce the humidity in greenhouse? A. Watering should be strictly controlled to prevent excessive indoor humidity. B. Proper ventilation after each watering and timely hoeing and loosening of soil C. In winter and spring production, clear-sky ditch irrigation or ramet irrigation can be selected, and Under-film irrigation can be used for plastic film mulching.
