Problems solved by technology

In the past, the irrigation of the test field was conducted by diverting water from canals and flooding the whole field, which could not be irrigated according to the needs of crop growth, which affected the accuracy of crop growth and experiments; long-term employment of manpower for irrigation was expensive and had a lot of randomness; large water volume Flood irrigation is easy to cause damage to land leveling. In the current situation of serious shortage of water resources, water resources cannot be fully utilized to cause waste

Embodiment 1

[0016] 1. System establishment:

[0017] 1.1 Field information collection:

[0018] Measure the effective irrigated land of the test field and the area of ​​each divided plot in detail, measure the length of the pipes required to connect each plot, understand the surrounding environment of the test field, and draw drawings.

[0019] Introduction and treatment of irrigation water:

[0020] Irrigation water does not have high requirements on water quality. It only needs to remove solid particles and sediment with large volume and specific gravity in the water body, so as to prevent the residue in the water body from entering the farmland to pollute the soil, affecting the growth of crops and preventing impurities from clogging the pipes, affecting the overall operation of irrigation. . Considering the surrounding environment of the test field and the ease of engineering construction, the water in the irrigation canal near the test field is used as the quantitative irrigation w...

Abstract

The invention discloses a quantitative-irrigation control system. An intelligent IC card water meter is adopted, users are built on a computer through an IC card reader, and the irrigated water amount every time is written in; when irrigation is carried out, an IC card is inserted into a card inserting slot of the water meter, and a water pump is started to irrigate land; when the amount of water passing through the water meter reaches the calibration amount of the IC card, a control valve is automatically closed by the water meter; at the moment, a computer terminal can receive an irrigation completing reminder and immediately switches off a water-pump switch. The quantitative-irrigation control system has the advantages that the quantitative-irrigation control system acts on an experimental field to improve the accuracy and the irrigating efficiency of a planting experiment, project funds are saved, waste of an irrigation water body is decreased, and automation of control is achieved; due to the quantitative water meter, timing and quantitative irrigation is controlled by the computer, and traditional irrigation modes such as labor flood irrigation are replaced; under the condition that the growing requirements of crops are met, water resources are effectively used, and meanwhile the irrigation system is stable and efficient in operation.

Description

technical field [0001] The invention relates to a quantitative irrigation control system. Background technique [0002] Gansu Provincial Academy of Agricultural Sciences Zhangye Water-Saving Agricultural Experiment Station is located in the nine-kilometer horticultural experiment field of Zhangye City. Zhangye City is 13 kilometers away. It belongs to the arid area where there is no agriculture without irrigation. The irrigated area belongs to the Daman irrigation area in the Heihe River Basin. The test field is 100m away from the test station, and it is the base for the test station to carry out various crop planting and water-saving experiments. In the past, the irrigation of the test field was conducted by diverting water from canals and flooding the whole field, which could not be irrigated according to the needs of crop growth, which affected the accuracy of crop growth and experiments; long-term employment of manpower for irrigation was expensive and had a lot of rand...
