Embodiment Construction

[0035] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] Such as figure 1 As shown, the embodiment of the present invention provides a lawn irrigation forecasting method, the method includes the following steps:

[0037] Step 1, determine the soil type, and call the soil moisture content calibration coefficient from the database;

[0038] Step 2, divide the lawn area, and measure the soil moisture content at multiple points in the same area to get the average value;

[0039] Step 3, determine the month, lawn type and maintenance level, and call the lawn growth water demand coefficient from the database;

[0040] Step 4. Determine whether the lawn needs water according to the parameters determined in Step 3 and Step 4. ...

Abstract

The invention discloses a method for forecasting the water saving irrigation of a lawn. The method comprises the following steps of: dividing rotational irrigation regions of the lawn, measuring the soil moisture content at several points in the same region and taking an average value as an actually-measured soil moisture content; determining the soil type and the lawn type, calling the calibration coefficient of the soil moisture content and the water demand coefficient for the growing of the lawn from a database; calculating whether the lawn is needed to irrigate according to the actually-measured soil moisture content and a lawn water saving irrigation decision forecasting model, if needed, determining the amount of irrigation water and the irrigation time. The method for forecasting the water saving irrigation of the lawn and the system thereof can assist lawn maintenance skilled workers and administrators to draw up a proper irrigation system to a large extent, the research result of the lawn irrigation is converted into the production practice of the lawn irrigation, thereby improving the quality of law maintenance, achieving the purpose of water saving irrigation and improving the utilization rate of water resources.

Description

technical field [0001] The invention relates to the field of farmland water conservancy engineering, in particular to a lawn water-saving irrigation forecasting method and system. Background technique [0002] my country is a country with relatively scarce water resources. Two-thirds of the cities in the country are short of water. It is lower than the lower limit of the international per capita water consumption of 1,000 cubic meters, and it ranks after the top 100 cities and capitals in the world. The insufficient supply of available water has become an important constraint factor for the sustainable development of urban economy. As Beijing is moving towards a first-class standard international metropolis, urban greening is essential, and the area of ​​lawns is increasing rapidly. According to statistics, the area of ​​lawns in Beijing has reached 50 million square meters, and the annual rate is 1.5 million square meters. increment. The average annual water consumption o...
