Water and fertilizer integrated device for saline-alkali soil

Abstract

The invention discloses a water and fertilizer integrated device for saline-alkali soil. The device comprises a housing, wherein a water inlet, a fertilizer inlet, a water and fertilizer outlet and acontrol assembly are all arranged on the housing; a water inlet valve and a water inlet flow meter are arranged at the water inlet; a fertilizer inlet valve and a fertilizer inlet flow meter are arranged at the fertilizer inlet; the water and fertilizer outlet is connected with the inlet end of a fertilizer outlet pump; the control assembly comprises a central control module and an interaction module; the central control module is respectively and electrically connected with the water inlet valve, the water inlet flow meter, the fertilizer inlet valve, the fertilizer inlet flow meter and the fertilizer outlet pump. When the device disclosed by the invention is used, the water inlet and fertilizer inlet flow can be collected by each corresponding flow meter and then transmitted to the control assembly, and the control assembly regulates the flow according to an actual needed water-fertilizer ratio, so that the water-fertilizer mixing ratio is accurately controlled and can be adjusted inreal time. Therefore, according to the water and fertilizer integrated device disclosed by the invention, the switch of each valve can be automatically controlled, the labor amount is reduced, and the fertilization accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of water and fertilizer devices, in particular to a water and fertilizer integrated device for saline-alkali land. Background technique [0002] Crops and trees planted in saline-alkaline sandy land also need regular fertilization. In the prior art, a certain amount of water and a certain amount of fertilizer are usually mixed together manually, the mixed water and fertilizer are packed in a container, and fertilization is realized by spraying. However, in the existing fertilization methods, the mixing ratio of water and fertilizer mainly relies on manual operation, so that the adjustment of the mixing ratio cannot be automatically adjusted according to the actual conditions of crops and trees, and when fertilizing large-scale crops and trees, The labor intensity is high and the efficiency is low. Contents of the invention [0003] In view of the above disadvantages, the purpose of the present invention ...
