Problems solved by technology

There are also some non-weighing methods, such as calculating by measuring the liquid flow of the plant stalk at a certain period of time or measuring the transpiration intensity and the leaf area of ​​the plant, or calculating by measuring the change of soil moisture content, the common deficiency is that the accuracy is not high
The advantage of the weighing monitoring method is that it can maintain the natural state of the growth of plants or vegetation, but the biggest obstacle is the contradiction between the range and the accuracy, that is, the larger the range, the lower the accuracy, and the cultivation pond or soil body of a shrub is less. Several tons in weight, up to tens of tons in weight

Abstract

The invention relates to a gravity type plant transpiration recorder which comprises a plant, a cultivating pond, a gravity boat, a water pond, a water supply system, a water drainage system and a data acquirer, wherein the plant is cultivated in the cultivating pond, the cultivating pond is placed in the gravity boat, the gravity boat is placed in the water pond and suspended in water, the water supply system comprises a water supply tank and a water supply pipe, a water outlet of the water supply pipe is connected with the water pond through a water pond water inlet, the water supply pipe is provided with a water supply measuring tipping bucket, the water drainage system comprises a water drainage box and a water drainage pipe, a water inlet of the water drainage pipe is connected with the water pond through a water pond water outlet, the water drainage pipe is provided with a water drainage measuring tipping bucket, and the water supply measuring tipping bucket and the water drainage measuring tipping bucket are respectively connected with the data acquirer. The difference between the water supply amount and the water drainage amount in the same time period represents the transpiration amount of the plant in the time period. The gravity type plant transpiration recorder keeps the natural state of plant growth, is suitable for automatic monitoring and recording of transpiration and evaporation of plant vegetation and soil in the natural state, and is simple in structure, convenient to operate and high in measurement precision. The monitored result is an actual transpiration water consumption amount of the plant in the natural state.

Description

technical field [0001] The invention relates to a monitoring device for plant transpiration water consumption, in particular to a gravity type plant transpiration recorder. The gravity plant transpiration recorder is suitable for automatic monitoring and recording of vegetation or soil transpiration and evaporation in the natural state. Background technique [0002] The transpiration of plants and vegetation and the evaporation of soil are one of the important observational research contents of plant ecology and soil ecology. At present, observations on plant (or vegetation) transpiration and soil evaporation can be roughly divided into two types: non-weighing and weighing. The non-weighing type is generally determined by maintaining a constant water level in a certain container. This method does not have the natural state of plant growth because the constant water level is controlled, thus reducing the scientific value of the observation data. There are also some non-weig...
