Resistance-type winter bamboo shoot detector and detection method

The invention relates to a resistance-type winter bamboo shoot detector, which consists of a storage battery direct-current power supply circuit (8), a ground resistance detection circuit (9), a single-chip microcomputer control circuit (10), a nixie tube display circuit (11), a sound-light prompt circuit (12) and a shell (6), and also comprises a nixie tube display screen (1), a sound generator or a light emitter (2), a storage button (3), a display mode control button (4) and a power supply main switch (5) which are arranged on the shell (6). Positive and negative probes (7) are installed on the bottom surface of the shell. The detection method of the resistance-type winter bamboo shoot detector is realized through four steps: selection of time, climate, forestland and detection and digging points, pretreatment before detection and digging, detection, and digging. The detector has functions of automatic relevant digital processing and sound/light display, and is suitable for dark places and bamboo shoot growers who start work early, knock off late and suffer from unsound eyesight; the detection reliability is high, the problems that a great quantity of holes are dig in the forestland, underground stems are broken during digging, the bamboo shoot bodies are crushed during digging and the yield of bamboo shoots and bamboos is influenced as a result of untargeted digging are prevented from occurring, the bamboo shoot digging efficiency is high, the detector is simple to operate and the manufacturing cost is low.
