Description

Technical Field

[0001] The invention relates to the technical field of grape cultivation physiology research, and in particular to a device and method for determining the water requirement law of grapes. Background Art

[0002] Grapes have high requirements for water, and strict control of soil moisture is a prerequisite for growing good grapes. Grapes require more water in the early growth period or vegetative growth period, and less water is needed in the late growth period or fruiting period when the roots are weak. It is necessary to avoid damaging the roots to avoid affecting the quality. Grapes are afraid of rain and dew. Years with heavy rain can easily lead to insufficient sunshine and restricted photosynthesis. Excessive absorption of water can easily cause branches to grow too long and humidity to be too high, which can easily cause various diseases, such as black pox and gray mold.

[0003] At this time, a device that can systematically measure the water demand of grapes is needed, but most of the existing devices cannot intuitively measure the water demand of grapes. Therefore, it is necessary to build an experimental system that can record the difference factors of experimental conditions. Such a system can accurately analyze the demand for water and fertilizer of grapes at different growth stages and their cultivation physiological characteristics, thereby providing scientific theoretical support for grape planting and production.
