Methods of daily maintenance of vegetable greenhouses
The framework of the vegetable greenhouse construction supports the transparent transparent plastic film to allow as much sunlight as possible to radiate in, so as to increase the temperature of objects such as soil and crops, and meet the photosynthesis and temperature requirements of crops. Another effect of the plastic film is to block the direct convection between the air in the shed and the outside air, and reduce the exchange of heat with the outside air.
Although the construction of vegetable greenhouses is good, there are many things that need to be paid attention to in the construction of vegetable greenhouses, especially when choosing the site for greenhouse construction. Vegetable greenhouses should be selected in places that are well sheltered from the wind, sunny, flat, fertile, well-lit, and well-ventilated. , the specific requirements are:
1. Site location: Because the construction of vegetable greenhouses is a facility with relatively large investment, and the period of use is generally relatively long, so for the convenience of management, it should be constructed in a centralized manner.
2. Sunshine and ventilation: Because the main light source of the vegetable greenhouse comes from solar energy, the ventilation and sunlight of the site must be good.
3. Water level measurement: Because vegetables need a lot of water, different regions have different requirements, but if the water level is too shallow, it is not suitable for the construction of vegetable greenhouses.
4. Land measurement: The fertility of the land directly affects the growth of vegetables, so the soil quality of the construction site needs to be in the early stage, so that the varieties can be selected and fertilizers can be allocated in the future.
5. Soil and water conservancy: Vegetable greenhouses are cultivated by multiple three-dimensional planting, so good soil environment and water conservancy advantages will greatly affect the choice of vegetable greenhouse construction.
