Fertilizer irrigation device for soilless culture

Abstract

The invention relates to a fertilizer irrigation device for soilless culture. The fertilizer irrigation device comprises a bottom disc. Walking wheels are arranged at the bottom of the bottom disc. A push-pull rod is arranged on the left side of the bottom disc. A controller is arranged at the left end of the push-pull rod. A display screen is arranged at the top of the push-pull rod. A fertilizer solution bucket, a proportioning pump and a clear water bucket are arranged at the top of the bottom disc. A water filling opening is formed in the upper portion of the clear water bucket. A liquidometer is arranged on the outer side of the clear water bucket. A fertilizer filling opening is formed in the upper portion of the fertilizer solution bucket. A water level floater is arranged in the fertilizer solution bucket. An outlet of the fertilizer solution bucket is connected with an opening A of a three-way connector through a filter A and a fertilizer solution inlet valve in sequence. An outlet of the clear water bucket is connected with an opening B of the three-way connector through a filter B, a water inlet valve and a flow sensor in sequence. An opening C of the three-way connector is connected with an inlet of the proportioning pump. The fertilizer irrigation device has the beneficial effects of being simple in structure, convenient to mount and demount and good in sealing effect.

Description

technical field [0001] The invention belongs to the technical equipment field of soilless cultivation, and in particular relates to a fertilization and irrigation device for soilless cultivation. Background technique [0002] The nutrients and water required for soilless cultivation of greenhouse crops need to be absorbed from the irrigation nutrient solution, so the integrated irrigation of fertilizer and water is one of the core technologies of soilless cultivation in greenhouses, and the development of supporting equipment for integrated irrigation of fertilizer and water is in line with the development of facility agriculture in China Demand is of great significance. Traditional fertilizer and water irrigation equipment usually uses a Venturi fertilizer applicator, but the uniformity and concentration of fertilizer and water cannot be precisely controlled, and the ratio of fertilizer and water required by crops in different growth stages is different. In order to ensure i...

Problems solved by technology

[0002]The nutrients and water needed for soilless cultivation of greenhouse crops need to be absorbed from the irrigation nutrient solution, so the integrated irrigation of fertilizer and water is one of the core technologies of greenhouse soilless cultivation , the development of supporting equipment for fertilizer-water integrated irrigation meets the development needs of my country's facility agriculture, and is of great significance. Traditional fertilizer-water irrigation equipment usually uses Venturi fertilizer applicators, but the uniformity and concentration of fertilizer and water cannot be precisely controlled, and crops are grown under different conditions. The proportion of fertilizer and water required in the growth stage is different. In order to ensure the fastest growth and development, it is necessary to develop a fertilization and irrigation device for soilless cultivation
