Problems solved by technology

However, due to the large differences in the crop coefficient due to the different regional environments and irrigation methods, the crop coefficient provided by FAO has a large deviation in the actual application process. In order to estimate the water demand of crops more accurately , it is necessary to establish the crop coefficient of the specific crop in the farmland according to the actual farmland specific environment and the moisture change of the farmland soil to improve the irrigation accuracy

Embodiment 1

[0045] like figure 1 , The present embodiment proposes a method of calculating the coefficient of crop, the method comprising:

[0046] S101, soil water in soil at different depths of the position detection, data acquisition soil moisture.

[0047] Specifically, the embodiment of the soil moisture in a manner different depths of the soil of the present embodiment detects the integration may employ a tubular soil moisture meter. Moisture sensor deployed at different depths of the tubular body, such as every 10cm deploy a moisture sensor. Using a moisture sensor tube at different depths can be acquired simultaneously to the soil where the soil moisture sensor depth data, parity data homologous, it is possible to perform data correlation analysis. Soil moisture meter can continue to support the work of detection meter long power supply through solar panels, the entire process of real-time detection of irrigated soil.

[0048] S102, the meteorological environment of the area where the...

Abstract

The invention proposes a crop coefficient calculation method. The method comprises the steps: detecting soil moisture at different depth positions in soil, and obtaining soil moisture data; detecting the meteorological environment of the area where the soil is located, and obtaining meteorological data; acquiring water demand of crops according to the soil moisture data; acquiring a reference evapotranspiration amount according to the crop water demand and the meteorological data; and calculating a crop coefficient according to the ratio of the crop water demand to the reference evapotranspiration. By acquiring the soil moisture data of different depth positions in the soil and the meteorological data of the area where the soil is located, the real crop coefficient can be obtained for specific crops, specific areas or specific irrigation modes, so that the irrigation precision is improved.

Description

Technical field [0001] The present application relates to the field of irrigation, particularly to a method and system for crop coefficient calculation. Background technique [0002] With the continuous development of social economy, water shortages have become increasingly prominent, rational development and efficient use of water resources is very important. Allocation of water use in agricultural irrigation accounts for about 80%. Irrigation in all types of surface irrigation area average about 98%, extensive irrigation methods, irrigation water use efficiency is low, so our special emphasis on "crop irrigation, soil without irrigation" water policy. Agriculture crop water requirement is the most important part of water consumption, irrigation and drainage is an essential basis for the implementation of water resources planning, management and farmland, therefore, to accurately estimate crop water requirement is particularly important, and the estimated crop water requirement ...
