Method and system for effectively reducing water consumption for improving saline and alkaline lands by irrigation for washing salt

Abstract

The invention discloses a method and system for effectively reducing the water consumption for improving saline and alkaline lands by irrigation for washing salt. The method comprises the following steps: an executing device is respectively connected with a parameter monitoring device, a data creating device, a selective input device and an saline-alkaline content tracking device and is used for transmitting and receiving all data generated by all the devices so as to calculate and analyze an optimal matching value of the water consumption of the improved area and obtain and execute a production mode with optimally-reduced water consumption for improving the saline and alkaline lands by irrigation for washing salt. The method and system disclosed by the invention has the beneficial effectsthat all parameters of the saline and alkaline lands improved by irrigation for washing salt can be completely and accurately controlled, so that the purposes of reducing the water consumption for improving the saline and alkaline lands by irrigation for washing salt and avoiding great waste of water resources are achieved.

Description

technical field [0001] The invention relates to improvement technology for improving saline-alkali land, in particular to a method and system for effectively reducing water consumption for improving saline-alkali land by irrigation and washing salt. Background technique [0002] Irrigation and washing salt is an important method of saline-alkali land improvement. Irrigate water into the saline-alkali land to form a certain depth of water layer on the ground to fully dissolve the salt in the soil, and drain the soluble saline-alkali in the topsoil to the deep layer through infiltration Into the soil or washed out, infiltrated into the drainage ditch to drain the dissolved salt, thereby reducing the saline-alkali content of the soil and achieving the purpose of improving saline-alkali land. At present, there is no strict planning for the demand for irrigation to improve saline-alkali land by washing salt with water. Most of them use experience to pour water into saline-alkali ...

Problems solved by technology

At present, there is no strict plan for the demand for irrigation to improve saline-alkali land by washing salt with water. Most of them use experience to pour water into saline-alkali land to dissolve the salt and drain it away, and then monitor whether the saline-alkali content of the saline-alkali land reaches the standard after the salt-dissolving and drainage In this way, in order to make the saline-alkaline content of the saline-alkali land reach the standard after drainage, the amount of water poured into the saline-alkali land is usually increased, resulting in a certain waste, making the water consumption of improving the saline-alkali land by irrigation and washing salt remain high. When salt is improved, this water consumption is very huge, causing a lot of waste of water resources
