Photovoltaic fertilization device for micro-moist irrigation

Abstract

The invention belongs to the field of a saline land moistube-irrigation apparatus technology, and relates to a photovoltaic fertilizing apparatus for moistube-irrigation. A tank and a filter barrel have openings at the tops, the filter barrel comprises two semicircular shaped barrels which are buckled together, a first gap is remained between two buckled surfaces of the filter barrel along the direction of the cross section, the first gap comprises an annular segment positioned in the middle part and two straight segments which are positioned at two sides of the annular segment and are communicated with the annular segment, a barrel wall of the filter barrel is provided with micropores, a second gap is remained between the barrel wall of the filter barrel and a sidewall of the tank, an electrothermal chassis is arranged at the bottom of the tank, the top of the tank is buckled with a charging cover, and the top of the charging cover is buckled with an outer cover; the sidewall of the tank is connected with an inlet pipe and an outlet pipe, the inlet pipe and the outlet pipe are respectively connected with a main pipe, the main pipe is connected with a branch pipe and a micro moistening pipe, so that the tank and the micro moistening pipe network are connected in parallel, a photovoltaic power generation system for supply supplying power for the electrothermal chassis is also provided; by means of solar energy generation, the photovoltaic fertilizing apparatus realizes integrated supply of water and fertilizer, and effectively solves the problems of slow fertilizer dissolving speed and low fertilizer supply efficiency.

Description

technical field [0001] The invention belongs to the technical field of micro-moisture irrigation devices for saline-alkali land, and relates to a photovoltaic fertilization device for micro-moisture irrigation. Background technique [0002] Micro-moist irrigation is a continuous micro-irrigation technology, a new underground precision micro-irrigation technology using semi-permeable membrane technology, and belongs to local irrigation. Micro-moisture irrigation, also known as semi-permeable membrane irrigation, is an emitter made of functional semi-permeable membrane materials, driven by the water potential gradient inside and outside the membrane, and according to the water demand of crops, it will provide real-time and automatic irrigation for the root zone of plants in a slow way. , Timely and appropriate continuous water supply. It has the advantages of low energy consumption, high water saving, low cost, and long service life, and is especially suitable for mountain ir...
