What conditions need to be met to build a greenhouse?

Greenhouses are mainly used for growing vegetables, fruits, flowers, etc. In the cold winter, the temperature inside the greenhouse can be changed to meet the growing environment of vegetables, fruits, and flowers, so that these items that only appear in summer can also be grown in winter. to be on people's dinner tables. Of course, for friends who grow greenhouses, they are more concerned about how to build them, what are the construction methods and requirements.

In fact, we know that for vegetables, in addition to temperature, all conditions such as humidity, breathability, ventilation, etc. must be met for their growth, as well as lighting, etc. This requires us to take all these issues into consideration when building a greenhouse. The editor has summarized the previous issues. There are a total of the following requirements.

1.Choose a place with open, flat terrain, or a sunny and gently sloping place to build a greenhouse. Such a place has good lighting, high ground temperature, and easy and even irrigation.

2.Greenhouses should not be built over air vents to reduce heat loss and wind damage to the greenhouse.

3.Greenhouses cannot be built in windy areas. Ventilation channels should be opened in windy areas before building the greenhouse. Otherwise, poor ventilation will lead to serious crop diseases. At the same time, too much snow in winter will also damage the greenhouse.

4.The greenhouse should be built with sandy loam soil. Such soil has a high temperature and is conducive to the growth of crop roots. If the soil is too sticky, add an appropriate amount of river sand and apply more organic fertilizer to improve it. The soil is too alkaline, so acidic fertilizer must be applied to improve it before building a greenhouse, and it can only be built after improvement.

5.Greenhouses cannot be built on low-lying and waterlogged plots. Drainage ditches must be dug first before building greenhouses. For plots where the groundwater level is too high and prone to anti-slurry, more soil must be padded and the terrain must be raised before greenhouses can be built. Otherwise, the ground temperature will be low and the soil moisture will be too much, which is not conducive to the growth of crop root systems.

6.The location where the greenhouse is built should have sufficient water resources, convenient transportation, and power supply equipment to facilitate management and product transportation.

7.The orientation of the greenhouse construction should be extended from north to south, and the sides of the greenhouse should face east and west, so that the light distribution in the greenhouse will be even. The distance between the left and right sides of the shed is 2/3 of the height of the shed. The distance between the two greenhouses is too large, which wastes land. Too close affects the light transmission and ventilation effect of the greenhouse, and it is also inconvenient to fix the greenhouse membrane and other operations.
