Second, product characteristics The soil moisture characteristic curve is usually measured by pressure membrane (chamber) and centrifuge. The author was informed that recently, 6. The soil moisture characteristic curve can reflect the water holding and releasing characteristics of different soils, and it can also understand some soil moisture constants and characteristic indexes of a given soil. 5., Ltd. Therefore, the soil water characteristic curve is an important and basic tool for studying soil water movement, adjusting and using soil water, and performing soil improvement.
If the soil moisture content is measured, the matrix potential value can be checked according to the soil moisture and soil characteristic curve, so as to judge the effective degree of the soil moisture content for plants. After more than 40 years of development, has successively designed and produced [...]
