Embodiment Construction

[0053] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0054] Such as figure 1 As shown, a long-sequence farmland irrigation quota calculation method includes the following steps:

[0055] Step 1: Establish a basic parameter database, use Access or SQL Server as the storage database, and enter basic parameters such as evaporation, precipitation, and depth of the soil plan wet layer into the database.

[0056] Step 2, compiling the calculation program, adopting Visual Basic computer language programming.

[0057] Step 3. Calculate the irrigation quotas for upland crops and rice separately: calculate the water demand of upland crops in the early sowing period, adjust the water demand for upland crops ...

Abstract

The invention relates to a long-sequence farmland irrigation quota measuring and calculating method which comprises the following steps: establishing a basic parameter database, and inputting farmlandbasic parameters into the database; Compiling a measuring and calculating program; Respectively calculating irrigation quotas of the dry crops and the rice; Further calculating a long-sequence comprehensive irrigation net quota according to the designed multiple cropping index on the basis of single crop irrigation quota calculation; And calculating the long-sequence farmland irrigation gross quota of each calculation partition according to the utilization coefficient of the irrigation water of each region. The long-sequence farmland irrigation quota measurement and calculation method can well overcome the problems of insufficient precision of irrigation quota and standard water quota in typical years, and can greatly improve the accuracy of agricultural water demand prediction results inwater resource planning, water resource development and utilization engineering scale demonstration, water resource demonstration report compilation and the like.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for measuring and calculating long-sequence farmland irrigation quotas. Background technique [0002] In the professional field of water resources, irrigation quotas are generally the basis for carrying out work such as water resource planning and scale demonstration of water resource development and utilization projects. Irrigation quotas are generally divided into typical annual irrigation quotas, local industry (standard) water quotas (agricultural sector) (hereinafter referred to as "standard water quotas") and long-sequence irrigation quotas. The farmland irrigation quotas in typical annual irrigation quotas and standard water quotas are all water quotas in a specific year or within a year. There are many studies on the calculation methods of annual quotas, and the technology is becoming more and more perfect. Compared with the typical annual irrigation water...
