Light intensity and growth of trees
The 358 fence is a dense mesh guardrail mesh. Due to its unique mesh size, it is generally used for security protection in airports, prisons and other places.

1. The relationship between light intensity and the growth of economic trees:
The effect of light intensity on the growth of trees can be reflected in the growth of shoots and root growth in shoots. The integrator showed that strong light impaired the upward growth of buds, while the growth of side buds increased, making the tree posture open or prone to dense stunts; while lack of light, the branches grew lengthy and erect, and showed strong growth and yellowing. According to the experiment, the general hi-light tree species exhibited longer growth and increased ancestral growth when the light was weakened (artificial shading or cloudy rainy days), but the weight did not increase, and the dry matter showed a decrease in performance, that is, it showed leggy. Light has a significant effect on the growth of trees and the formation of morphological structures. Light energy promotes the enlargement and differentiation of cells, and controls the division and elongation of cells. Therefore, in order for trees to grow normally, not only to increase the volume, but also to increase the weight, appropriate light intensity must be available.
The light intensity also shows an indirect effect that is easily overlooked on the roots of trees. When the light is insufficient, there is a significant inhibitory effect on the growth of the root system, the amount of root elongation is reduced, the number of new roots is small, and even the length of the cattle is stopped. Although the root system grows in the absence of light in the soil, its source of material is still mostly from the assimilation material in the shoot. When the amount of assimilation decreases, the assimilate decreases. It is first used on the ground and then sent to the root system, so the rainy season has a great influence on the growth of the root system, while the shade-tolerant tree species form a low light compensation point to adapt to its environmental conditions.
Because of the lack of light state, the tree body grows too long or yellow, and poor root growth will inevitably lead to bad mature tree shoots. In addition, light can inhibit germ activity to some extent. For example, the tree disease in sites with better sunshine conditions has been significantly reduced.
Excessive light can cause irritation, especially in continental climates, sandy areas, and the drastically changing temperature difference between day and night. After the leaves and branches are illuminated by strong light, the leaves can be increased by 5 to 10°C and the bark can be increased by 10 to 15°C. When the trunk temperature is more than 50Y or lasts for 2h in 40 houses, sunburn will occur. Sunburn is closely related to light intensity, tree vigor, crown part, and branch thickness.
2. The relationship between the intensity of first illumination and reproductive growth of economic trees:
The intensity of light is closely related to the formation of flower buds in trees. Insufficient illumination is not conducive to flower bud differentiation. Fruit set-up rate is low, fruit development stops midway, resulting in fruit drop. In addition, light has a significant effect on the quality of fruit. For example, under various conditions of air and light, fruit trees are better colored, and the fruit color is improved. Sugar content and vitamin C content, reduce acidity, enhance storage stability. The content of anthocyanin in fruits is closely related to the light intensity, and the anthocyanins form much more under strong light and low temperature conditions. When growing trees in a greenhouse, using artificial light to extend the time is generally beneficial to their growth, flowering, and results.
It can also called Security Anti-Climb 358 Fence,Anti Climb Prison 358 Security Fence,Barbed Wire 358 Fence
The origin of the name of the 358 fence is inseparable from its mesh size:
"3" corresponds to a 3-inch long hole, which is 76.2mm;
"5" corresponds to a short hole of 0.5 inches, which is 12.7mm;
"8" corresponds to the diameter of No. 8 iron wire, which is 4.0mm.
So to sum up, the 358 guardrail is a protective mesh with a wire diameter of 4.0mm and a mesh of 76.2*12.7mm. Because the mesh is extremely small, the mesh of the entire mesh looks dense, so it can sometimes be called It is dense mesh.
It is very suitable to be used as a fence net for safety protection. Because of the special mesh size of the 358 fence, it is difficult for ordinary climbing tools or fingers to climb, and it is difficult to cut it even with the help of large scissors, so if you It is used as a fence net for safety protection, so there is no problem in choosing it.
