Soil pH affects the growth of plants directly. It is difficult for ordinary people to identify soil pH. The pesticide network has compiled information on how to identify soil pH:
First, the sense of judgment.
Generally, the soil with too much acidity is rotted when wet, and when it is dry, it is formed into a large hard block, and some small entrances have a bitter taste. In the alkaline soil, after the rain, the soil is crusted and loose when dry. Put the loose soil into the water and turbid, clarify and take the clear liquid to boil. The bottom layer has a little white frost.
Second, judge according to the instructions.
If the following plants grow lush (well growing) on ​​or near the plot, they can be compared and identified: T. chinensis, Pinus massoniana, Arbutus, platter, and Azalea, which are grown in acid yellow loam, are identified as indicator plants of acid soil. ; 蜈蚣è‰,å›å¶ä¹ŒæŸ, like to grow on alkaline calcareous soil, is identified as an indicator plant of calcareous soil; alkali stalk that grows on alkaline soil that is strongly alkaline, is confirmed as an indication of alkaline soil plant.
1, look at the soil source: generally collected from the mountains and rivers, gully humus soil, mostly dark brown, relatively loose, fertile, good permeability, is an ideal acid humus soil. Such as: pine needle humus soil, grass charcoal humus soil.
2, look at the earth color: acid soil is generally darker in color, mostly dark brown, while the alkaline soil color is mostly white, yellow and other light colors. In some saline-alkali areas, soil surface often has a layer of white powdery alkaline substances.
3. Look at the surface plants: When excavating the flower soil in the wild, you can observe the plants growing on the surface. Generally, the soils of wild rhododendrons, pines and cedars are mostly acidic soils; while the soils growing in the willow, millet and sorghum areas are mostly It is alkaline soil.
4, look at the texture: acidic soil texture loose, breathable and permeable water; alkaline soil texture is hard, easy to form a block, poor ventilation and water permeability.
5, by hand: acidic soil in the hands of a "soft" feeling, after loosening the soil, the soil is easy to spread, not easy to agglomerate; alkaline soil in the hands of a "hard" feeling, easy to agglomerate after loosening Do not spread out.
6. Look at the situation after watering: the acidic soil is infiltrated faster after watering, no white foam is formed, and the water surface is relatively sloppy; after alkaline soil watering, the infiltration is slow, the water surface is white foaming, foaming, sometimes There is also a layer of white alkaline material around the flower pot.
7. Use pH test paper to measure the acidity and alkalinity of the soil by immersing some soil samples in cold water, immersing a part of the test paper in the soaking liquid, taking out, observing the color change, and then measuring the color and the color chart. In comparison, if the pH is 7, the soil is neutral; if the pH is <7, it is acidic; if the pH is > 7, it is alkaline.
