A Little Wisdom Helps You Become Smarter !

The simple arched shed for watermelons has only arched pipes without columns and horizontal braces. Its advantages and disadvantages are as follows :

Advantages:

Firstly, the space inside the shed is open. Without the obstruction of columns and horizontal braces, it is convenient to carry out farming operations in the shed. Activities such as soil preparation, fertilization, and watermelon harvesting will be relatively easy, and it is also easier for large agricultural machinery to enter and exit. The effective utilization of space is relatively large !

Secondly, the light distribution is even. This structure will not create shadows like the arched shed with columns, enabling watermelon plants to fully receive sunlight, which is beneficial to the photosynthesis of watermelons and promotes their growth and sugar accumulation !

Thirdly, the ventilation performance is relatively good. Without redundant structures in the way, air can flow more smoothly inside the shed, which helps to adjust the temperature and humidity in the shed and reduces the risk of pest and disease occurrence !

Disadvantages :

Firstly, the structural stability is slightly poor. Compared with the arched shed reinforced by columns and horizontal braces, this simple arched shed is more likely to be damaged when encountering severe weather such as strong winds and heavy snow. For example, it may be blown down by strong winds or collapsed by snow accumulation !

Secondly, the heat preservation performance is limited. Since there are no other auxiliary heat preservation structures, during periods of low temperature, such as early spring or late autumn, this kind of arched shed may not be able to maintain the temperature inside the shed well, which has certain limitations on the growth of watermelons !
