A plant water consumption measurement and water control device

Abstract

The invention relates to the technical field of plant culture, and particularly relates to a plant water consumption measurement and water controlling device. The device comprises a sealing cover, a water seepage bucket body and a sealing bottom cover, wherein a first opening and a first through hole for the passing of plantlets are formed in the sealing cover, and the first opening cuts the side wall of the sealing cover and is connected to the first through hole; the walls of the two sides of the first opening are in disassembly connection, the sealing cover is in disassembly connection with a port of the water seepage bucket body and is in sealing connection with the port of the water seepage bucket body in use, and the sealing cover is covered on the bucket port of the water seepage bucket body in use; water seepage holes are formed in the bottom of the water seepage bucket body, the sealing cover is in disassembly connection with the bottom of the water seepage bucket body and is in sealing connection with the bottom of the water seepage bucket body in use, and a sealing bottom cover is placed below the bucket bottom in use. The plant water consumption measurement and water controlling device provided by the invention has the advantages that the airtightness is good, the result of the measured plant transpiration water consumption is exact, in addition, the device is also provided with a sealing gasket, a gasket and the like, so that the sealing effect of the whole water controlling device is further enhanced.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a plant water consumption measurement and water control device. Background technique [0002] In field experiments, the control of soil moisture for plant growth is generally based on soil water content indicators (quality water content, volume water content) or soil water potential, and different amounts of irrigation or water regulation are performed on the soil according to changes in its value. However, under the conditions of laboratory measurement or facility cultivation, the potted method can be used to calculate the soil quality water content by measuring the change of the potted plant quality. Since the measurement of the quality water content is more reliable than other indicators, it can control the soil moisture more accurately; potted plants Compared with field regulation, the method has more controllable changes in soil moisture, and can accurately measure...

Problems solved by technology

[0004] In this way, even after the upper surface is covered with a film, part of the water vapor still loses from the retained air holes or the contact surface between the film and the flower pot; It is inconvenient; if the pot body leaks, the water for irrigation will be lost, that is, there is no more reasonable potted water control device in the prior art to realize the measurement of plant transpiration water consumption, and it can only be measured by simple film covering. Determination of water consumption, because the sealing of the pot cannot be guaranteed, the measured water consumption of plant transpiration is not very accurate, and there is a large error
