Application of soil hardness tester in urban greening
In the process of urban construction, urban afforestation is one of the important contents. These urban plants play an important role in improving the urban air environment and creating a beautiful urban space. However, urban soils are different from agricultural soils, and urban soils are Long-term human activities, measured using a soil hardness tester, will show that the hardness is relatively high, and the soil environment with high soil density is not conducive to plant growth. Therefore, in order to ensure the urban greening effect, the growth of these garden plants will be promoted. It is necessary to use a soil hardness tester to improve the soil environment in urban greening.

The density of urban soil is significantly greater than that of suburban soil. This is a prominent feature of urban soils. In general, the depth of human-induced trampling is 3-10 cm. The soil hardness tester found that the hardness of such soil is 14-28 kg/cm2. In the meantime, the depth of car rolling impact is 30-35cm, and the soil hardness is found to be 10-20kg/cm2 using a soil hardness tester. In some areas that are mechanically compacted, the hardness of the soil is greater. Soils with high soil hardness affect soil permeability, drainage, and water holding capacity. The invisibility of garden plants is an obstacle to the extension of root systems. The absorption of nutrients and water by roots of nutrient plants causes poor growth of trees, even in severe cases. Cause the root tissue to suffocate.
Before planting these garden plants, first use the soil hardness tester to survey the soil hardness of the planted city, then you can clearly know the current soil hardness situation, determine whether it has the conditions for planting, and if the soil hardness is found to be substandard, So, we can also adopt targeted measures to improve. Soil environment with moderate soil hardness can be improved not only by improving the survival rate of planting garden plants but also by ensuring that these garden plants can be planted in good quality. The urban greening effect shows that the application of soil hardness meter in urban greening is very necessary and very important.
