[0002] Grassland is a kind of earth ecosystem. The growth of grassland plants cannot be separated from water. The soil moisture content directly affects the germination, growth rate and health of plants. Different grassland plants have different adaptability to soil moisture. Through soil moisture testing, we can understand which areas are suitable for the growth of drought-resistant plants and which areas are suitable for the growth of moisture-resistant plants. This is helpful to study the distribution pattern of grassland plants and their succession laws.

[0003] Usually, a soil moisture detection device is used to detect the moisture of the soil. The soil moisture detection device is composed of a probe, a microprocessor, a display screen and a battery.
