PROBLEM TO BE SOLVED: To provide an examining system for cultivation environment, capable of accurately performing a proper examination of a cultivation environment for plants through directly measuring the plant activity of plants set on a cultivation medium (such as earth), especially pressure produced in the tissue of a root system and stem. SOLUTION: This examining system for cultivation environment comprises measuring the activity of plants 2 cultivated on a cultivation medium 1 so as to perform a proper examination of a cultivation management or a cultivation environment. The system has: a test plant 3 which is planted on the cultivation medium 1 and whose stems or branches are cut; a root pressure measuring means 4 which is attached to the cut part of the root, stem or branch of the test plant 3 and monitors the root pressure of the test plant 3 for a fixed period; and a cultivation environment examining means 9 which performs a proper examination of a cultivation management or a cultivation environment, based on root pressure data for a fixed period, monitored in a root pressure measuring process 4.
