[0003] During the substrate cultivation process, the water irrigated into the substrate cannot be completely absorbed by the substrate, and about 30% of the water will flow out.

[0004] Parameters such as the amount of irrigation return liquid, EC value and pH value are very important data indicators. It can well reflect the absorption of nutrients by crops and whether the irrigation amount is suitable for crops. These data can better help growers adjust irrigation strategies and fertilization formulas, which are more conducive to crop growth and achieve higher crop yields. However, there is currently no reliable and effective means to automatically collect return liquid and analyze the above indicators.

Since soilless cultivation mode irrigation is very frequent, measurement is required every time. If it is entirely dependent on manual measurement, it will be very labor-intensive, and the accuracy and timeliness of the data cannot be guaranteed. Utility Model Content
