Description

Technical Field

[0001] The utility model relates to the technical field of leaf surface nutrition detection, in particular to a leaf surface nutrition detection machine. Background Art

[0002] The blade is the main part of the leaf, usually a very thin flat body, which is conducive to the penetration of light into the leaf tissue and the absorption of light and carbon dioxide over the largest area for photosynthesis.

[0003] The leaves have an upper surface and a lower surface. Some plants have various hairs on both sides of their leaves or only on the back, such as soft hairs, downy hairs, stiff hairs, prickly hairs, scaly hairs, or branched star-shaped hairs radiating in all directions.

[0004] The photosynthesis and transpiration of leaves are mainly carried out through the leaves. The full shape of the leaf is called the leaf shape, the top is called the leaf tip or leaf tip, the base is called the leaf base, and the periphery is called the leaf edge. There are many veins distributed in the leaf.

[0005] Theories that explain the origin of leaves include the "apical branch theory" and the "stress feedback theory".

[0006] Many green plants and green vegetables also adopt a commercial model. Green plants and green vegetables grown in natural environments sometimes need to be transported over long distances, which is not only costly, but also impossible to supply in large quantities in a short period of time. Green plants and green vegetables may also become corrupt or damaged during long-distance transportation. Therefore, more and more artificial cultivation is now adopted. Artificial cultivation needs to simulate the natural growth environment of these plants. In order to understand the growth conditions of plants under artificial cultivation, it is necessary to manually collect plant samples and conduct sample tests on the growth conditions of plants. At present, manual sampling and testing are basically adopted. However, with the continuous expansion of artificial cultivation, it is desired to understand the growth conditions of plants in real time. Therefore, a technology that can realize automatic sampling and automatic detection is urgently needed to solve this problem existing in the prior art. Utility Model Content
