Problems solved by technology

[0002] At present, in agriculture, it is difficult to control the amount of water injection in water-saving irrigation field experiments. There are a lot of labor and equipment, but they cannot solve the problem that under different water injection amounts and different test quotas, it is necessary to rely on other meters to be very accurate. The realization of the quota is extremely poor, which reflects the defects of time-consuming and labor-intensive

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0034] refer to figure 1 , a method for water-saving irrigation using a U-shaped device, comprising the steps of:

[0035] The first test field 1, the second test field 5 and the U-shaped device are selected, and a ridge 4 is set between the first test field 1 and the second test field 5, and the U-shaped device is buried on the ground between the first test field 1 and the second test field 5. On both sides of the ridge 4, the two test fields are separately provided with Yellow River water irrigation outlets, and each irrigation outlet is controlled separately, and the bottom of the U-shaped device is buried on both sides of the ridge between the first test field 1 ...

Abstract

The invention relates to the technical field of agricultural irrigation and discloses a water-saving irrigation method with a U-type device and the U-type device. The method comprises arrangement of the U-type device and dynamic calculation of water control indexes to obtain the specific dimensions of the U-type device. The U-type device comprises a first round tube vertically buried inside a first test field and a second round tube inside a second test field; the lower ends of the second round tube and the first round tube are horizontally connected with a communicating tube. According to thewater-saving irrigation method with the U-type device and the U-type device, by means of water storage depths produced by different irrigation amounts in the fields, water injections volumes can be converted into millimeters to indicate the water saving range for experimental design; by determining the heights of both sides of different U-type devices, the U-type devices can be horizontally mounted among the processes of the experimental design; during water injection, by observing the instantaneous values of different irrigation amounts in the fields through the U-type devices, the aim of injection control can be achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a method for water-saving irrigation using a U-shaped device and the U-shaped device. Background technique [0002] At present, in agriculture, it is difficult to control the amount of water injection in water-saving irrigation field experiments. There are a lot of labor and equipment, but they cannot solve the problem that under different water injection amounts and different test quotas, it is necessary to rely on other meters to be very accurate. The realization of the quota is extremely poor, reflecting the time-consuming and labor-intensive defects. Contents of the invention [0003] The present invention proposes a method for water-saving irrigation using a U-shaped device and the U-shaped device to solve the problems raised in the above-mentioned background technology. [0004] The present invention proposes a method for water-saving irrigation using a U...
