Abstract

The invention discloses a farm irrigation indicating device, which comprises an evaporating dish and a water-replenishing sealing box, wherein the evaporating dish is covered with a mesh cover corresponding to the growth period of crop; the water-replenishing sealing box is connected with the evaporating dish via a connecting pipe; the water level in the water-replenishing sealing box can be displayed by self; the water-replenishing sealing box is provided with a water filling hole with a sealing plug; the top cover of the water-replenishing sealing box is provided with a ventilating pipe in integral structure with the top cover; the ventilating pipe is inserted into the water-replenishing sealing box; the end part of the ventilating pipe is near the bottom of the water-replenishing sealing box; and the connecting pipe is provided with a tong. According to the farm irrigation indicating device disclosed by the invention, the farm water consumption amount can be accurately reflected, and the production cost is low. The invention also discloses a use method used for the farm irrigation indicating device. The method is favorable for the device to accurately reflect the farm water consumption amount and is convenient for the device to indicate the reasonable irrigation time.

Description

technical field [0001] The present invention relates to the technical field of agricultural irrigation, more specifically, to a farmland irrigation indicating device, and also to a method for using the above-mentioned farmland irrigation indicating device. Background technique [0002] With the development of the times, the rural population is decreasing day by day, and the trend of large-scale agricultural production is becoming more and more obvious. Large-scale agricultural production requires a reasonable irrigation plan, and accurate determination of crop evaporation is an important factor in making an irrigation plan. [0003] In the prior art, instruments such as lysimeters are used to directly measure farmland water consumption. This method has the advantage of high measurement accuracy. However, the above-mentioned lysimeters and other farmland water consumption measuring instruments are very expensive and costly. [0004] To sum up, how to provide a farmland irrig...
