Glass Agriculture Greenhouse For Tomato lettuce and strawberry
growing
Product Description
Glass greenhouse is a greenhouse with glass as transparent covering
material. In foundation design, in addition to meeting the strength
requirements, it should also have sufficient stability and ability
to resist uneven settlement. The foundation connected to the
support between columns should also have sufficient horizontal
force transmission and spatial stability.
The bottom of the greenhouse should be located below the frozen
soil layer. The heating greenhouse can consider the effect of
heating on the freezing depth of the foundation according to the
climate and soil conditions.
The bottom of the foundation should be more than 0.5 meters below
the outdoor ground, and the distance between the top of the
foundation and the outdoor ground should be greater than 0.1 meters
to prevent the foundation from being exposed and adversely
affecting cultivation. Except for special requirements, the
distance between the top surface of the greenhouse foundation and
the indoor floor should be greater than 04 meters
How to lower the temperature?
1. Exterior Sunshade System
It is to shield the excess sunlight outside the glass greenhouse
and form a shade to protect the crops in the greenhouse.The
temperature in the greenhouse is maintained at a suitable
temperature.
Suitable temperature. This can effectively block direct sunlight
from crops without affecting natural ventilation in the
greenhouse.The cooling effect is better than internal shading, but
external covering is required.Positive material is sturdy, durable,
small stretch, anti-aging.
2. Natural Ventilation
There are three main advantages to using the natural passage
method: one is to eliminate the residual heat in the shed and
reduce the temperature; the other is to eliminate the excess
moisture in the shed and reduce the humidity; the third is to
adjust the indoor air content and increase the carbon dioxide
content in the air. To increase photosynthesis. At the same time we
must pay attention to increasing the ventilation area, continuous
butterfly-type windows that can be used at the top of the
greenhouse and increase the ventilation area of the side windows
around. In this way, in the season when the spring and autumn are
not too hot, the natural convection ventilation of the air through
the side window and the top window can reduce the temperature.
Groundwater resources can be used, coupled with heating and cooling
units, which can not only cool down and heat up, but also
environmental protection and energy saving, but the cost is
currently too high.
