[ Focus on Chemical Machinery Equipment Network ] March 12 is China's Arbor Day, whose purpose is to promote greening and protect the ecological environment.
In 1978, to protect Northeast, North China and Northwest China from sandstorms, my country launched the "Three Norths" Shelter Forest Project.
Since then, our country has made efforts for several generations and achieved world-renowned achievements in afforestation.
In 2019, NASA published a report saying that China is an important contributor to the greening of the earth.
In 20 years, 25% of the newly added 5% of the green area came from China, and nearly half of the net increase in vegetation leaf area contributed by China was attributed to it.
For planting trees and afforestation.

For planting trees and afforestation.
More than 40 years of tree planting and afforestation have made improvements to the ecological environment visible to the naked eye, not only the increase in green areas, but also the relief of sandstorms, desertification problems, and the restoration of oasis environments.
These results not only come from the efforts of generations of "tree planters", but also from scientific afforestation methods.
Afforestation is not simply a matter of planting saplings, but also to ensure the survival rate of the trees, so as to avoid the situation that "the trees are planted without trees, and the afforestation is difficult to become a forest.
" Scientific afforestation requires scientific instruments in many aspects.

Afforestation is not simply a matter of planting saplings, but also to ensure the survival rate of the trees, so as to avoid the situation that "the trees are planted without trees, and the afforestation is difficult to become a forest.
" Scientific afforestation requires scientific instruments in many aspects.
The afforestation project starts from the afforestation planning and design.
An important part of afforestation planning and design is the site survey of afforestation, that is, investigating the natural environmental factors related to the growth and development of forests, including topographic factors, soil factors, hydrological factors, biological factors, etc.
Topography, soil and vegetation are the main objects of site survey.
Topographic factors include slope, aspect, altitude, ratio of bare rock, etc.
, soil factors include dry humidity, pH value, soil layer thickness, humus thickness, etc.
, vegetation factors include dominant species , Coverage, etc.
Although this part mainly done manually, but in the investigation section factors may also be utilized detector obtains more detailed data, such as soil testing equipment, water quality analysis equipment and so on.

Through site investigation, you can choose tree species suitable for local afforestation conditions and afforestation methods (seed flying sowing, seedling planting, etc.
).
The quality of seedlings is a key factor affecting the survival rate of forest trees.
Therefore, the quality of seedlings needs to be inspected before sowing.
In particular, the quality of seedlings cannot be accurately judged by the naked eye, and seed testing equipment is needed for testing.

Therefore, the quality of seedlings needs to be inspected before sowing.
In particular, the quality of seedlings cannot be accurately judged by the naked eye, and seed testing equipment is needed for testing.
In order to ensure the survival rate, it is first necessary to screen out seeds with pests, damaged epidermis, and obvious damage, which can be simply screened using the clarity workbench.
The moisture content of the seeds can be detected by equipment such as a blast drying oven or an infrared rapid moisture analyzer.
In addition, seed X-ray machines, seed aging boxes, etc.
are also commonly used equipment for testing seed quality.
In order to inspect the germination rate of seeds more intuitively, germination tests can also be carried out with the help of a seed incubator.

After the seeds are planted or the seedlings are planted, on the one hand, it is necessary to understand the environmental changes of the afforestation land through meteorological and environmental monitoring, and to respond to possible meteorological disasters and environmental changes in a timely manner.
On the other hand, the forest trees can be monitored by means of hyperspectral remote sensing.
The growth of forests, and the results of afforestation can be evaluated by means of manual patrols.
In addition, the impact of forest trees on the environment after they have grown requires environmental monitoring equipment to record.

The scientific afforestation methods and the painstaking efforts of our country’s "tree planters" not only built a green Great Wall for our country and blocked the process of land degradation, but also made great contributions to the ecological and environmental protection of our country and the world.
We rely on afforestation to improve the destroyed environment little by little, regain lost land from the desert, and realize the legend of turning a desert into an oasis.
However, the protection of the environment still has a long way to go and requires everyone's efforts.
