Sunburn, also known as sunburn, harms fruits and branches, and is particularly harmful to sunny areas. The damaged fruit initially appears yellow, green, or light white, round or amorphous, and later turns brown with necrotic patches. Sometimes there is a red halo or depression around it, and the flesh is cork like, which can easily form deformed fruits. The main trunk and large branches are infected with the disease, and irregular burnt patches appear on the sunny side, making them susceptible to infection by decay bacteria, leading to decay or weakening of tree vigor.

Build an orchard anti sunburn system to reasonably reduce the damage of ultraviolet radiation to vegetation; Through the cooperation with Qingdao Agricultural University, a variety of colored mesh transmittance tests were conducted, and the multi-functional protective mesh achieved a shading rate of 10-20%; Reasonable shading can not only avoid the damage of ultraviolet rays to fruits and trees, but also reduce the intensity of ultraviolet rays. Even during the high light period at noon, it does not affect the photosynthesis of vegetation.

The orchard sunburn prevention system consists of two parts: a high-strength prestressed cement column support system and a multifunctional protective net. The foundation must be firm, and in order to extend the service life of the protective net, it should be promptly folded and protected during the unused season.
