Water and fertilizer integration system for mountainous and hilly regions

Abstract

The invention relates to a water and fertilizer integration system for mountainous and hilly regions. The water and fertilizer integration system comprises a water supply device, a fertilizer supply device, a stirring device, a spraying device, a recycling device and a control device, wherein the water supply device communicates with the stirring device; the fertilizer supply device communicates with the stirring device; the stirring device communicates with the spraying device; a delivery pump is arranged on a delivery pipe; the recycling device comprises a waste liquid recovery pipe, a recovery tank, a waste liquid pump, a waste liquid inlet pipe and a first electromagnetic valve; the spraying device, the waste liquid recovery pipe, the recovery tank, the waste liquid inlet pipe and thedelivery pipe sequentially communicate with one another; the waste liquid pump is arranged on the waste liquid inlet pipe; the first electromagnetic valve is arranged at the connected part of the waste liquid inlet pipe and the delivery pipe; and a water suction pump, a fertilizer pump, the delivery pump and the waste liquid pump all are in communication connection with the control device. According to the water and fertilizer integration system for the mountainous and hilly regions, one separate pump is arranged at each fertilizer and water source outlet and the working time of the pump is controlled, so that accurate proportioning of water and a fertilizer is achieved. Meanwhile, residual water and fertilizer can be recovered for irrigation, so that the water and the fertilizer are prevented from corroding the pipes and recycling of the water and the fertilizer is improved.

Description

technical field [0001] The invention relates to a water and fertilizer integration system for mountains and hills, belonging to the field of water and fertilizer integration equipment. Background technique [0002] Water and fertilizer integration technology is a new irrigation and fertilization technology produced under the development of modern agriculture, and it is a new agricultural technology that integrates irrigation technology and fertilization technology. Water and fertilizer integration technology dissolves fertilizer into irrigation water to make a water-fertilizer solution with a certain ratio according to the crop's demand for water and nutrients and the current status of water and nutrient content in the soil. Root soil keeps the water and nutrient content in the soil within the most suitable range for crop growth. It is a new type of irrigation and fertilization technology to achieve efficient use of water and fertilizer. [0003] my country's hilly and moun...

AI Technical Summary

Problems solved by technology

[0003] my country's hilly and mountainous areas have a vast territory, but most of the plots are small in scale and the land is very uneven. Agricultural production is mainly completed by manpower and animal power, and it is difficult to implement large-scale mechanized production

And in mountainous and hilly areas with large terrain slopes, although the sunlight is relatively sufficient, but the slope is large and the soil layer is thin, organic matter is not easy to accumulate and soil erosion is not easy to occur in plain areas.
