Irrigated fertilization equipment and irrigated fertilization method

Abstract

The invention discloses irrigated fertilization equipment and an irrigated fertilization method, and relates to the field of farm irrigation. The irrigated fertilization equipment and the irrigated fertilization method are used for solving the problem that existing farm irrigation water sources are deficient. The irrigated fertilization equipment comprises a sewage pool, a sewage pump, a processor, an absorbing solution storage pool, an absorbing solution pump and a fertilizer solution storage pool. The process comprises an inner cylinder and an outer cylinder which are arranged in a sleeved mode. The inner cylinder is a tubular forward osmotic membrane assembly. The sewage pool is connected with the inner cylinder through a pipeline. The sewage pump is arranged on a pipeline between the sewage pool and the inner cylinder. The absorbing solution storage pool is connected with the outer cylinder through a pipeline. The absorbing solution pump is arranged on a pipeline between the absorbing solution storage pool and the outer cylinder. A water outlet of the outer cylinder is communicated with the fertilizer solution storage pool through a pipeline. After sewage passes through the processor, water molecules in the sewage enter an absorbing solution under the effect of osmotic pressure, and the absorbing solution is diluted to obtain an irrigation water source. The irrigated fertilization equipment is used for farm irrigation.

Description

technical field [0001] The invention relates to the field of farmland irrigation, in particular to a farmland irrigation and fertilization equipment and an irrigation and fertilization method. Background technique [0002] The rapid increase of the world's population puts the food supply under enormous pressure. When the area of ​​arable land cannot be greatly increased or even reduced due to urban construction and industrial production land, increasing food production can only rely on large-scale use of fertilizers. At the same time, food production also consumes a lot of water resources. According to statistics, about 70% of the earth's available water is used for agricultural production. Therefore, sustainable agricultural production requires solving the problem of agricultural water use. [0003] In recent years, the rapid development of membrane separation technology has made the application of this technology more and more extensive. Forward osmosis (FO) refers to t...
