Planting bed irrigation device utilizing capillary action of planting medium

Abstract

The invention relates to a planting bed irrigation device utilizing the capillary action of a planting medium, belonging to the field of hydraulic engineering, wherein the IPC international patent class number is E02B 13 / 00. The planting bed irrigation device comprises a planting nursery bed, a nutrient fluid tank, a water supplying and pressurizing device, a water supply pipeline, a fertilizing device, a water discharging pipeline, an ultraviolet disinfection device, an intelligent controller and the like. The irrigation water treated by the ultraviolet disinfection device enters the nursery bed under the control of the intelligent controller. After optimal soaking time is achieved, a water discharging valve is opened, and the residual water enters a water storage tank by a discharged water collecting system and then treated by the ultraviolet disinfection device to be qualified so as to be used as water for next nursery bed or next irrigation. By adopting the planting bed irrigation device provided by the invention, the problems that the utilization efficiency of irrigation water is low, water distribution in the planting medium is not uniform, the relative humidity in the facility is not easy to control, the nutrient fluid is easily sprayed to flowers and leaves to cause burn and influence economic benefit, the labor management and maintenance cost is high and the like of the traditional irrigation technique for the facility flowers are overcome.

Description

1. Technical field [0001] The invention relates to a cultivation bed irrigation device utilizing the capillary action of the cultivation substrate, belongs to the field of water conservancy engineering, and its IPC international patent classification number is E02B 13 / 00. 2. Background technology [0002] The water and fertilizer utilization rate in the field of soilless cultivation in my country is only 30% to 40%, which not only causes waste of resources, but also causes environmental pollution due to inefficient use of fertilizers, and wastes a lot of energy. At the same time, the irrigation uniformity of high-grade flowers in facilities is low, the level of automation is not high, the production efficiency is extremely low, and the product quality needs to be improved urgently, which is not conducive to the flower planting industry and industrial development. The main irrigation technologies in the high-end soilless cultivation industry in my country include mobile pipe ...

Problems solved by technology

[0002] The utilization rate of water and fertilizer in the field of soilless cultivation in my country is only 30% to 40%, which not only causes waste of resources, but also causes environmental pollution due to inefficient use of fertilizers, and wastes a lot of energy

At the same time, high-grade flowers with low irrigation uniformity, low level of automation, extremely low production efficiency, and urgent improvement in product quality are not conducive to the flower planting industry and industrial development

The main irrigation technologies in the high-end soilless cultivation industry in my country include mobile pipe irrigation and drip irrigation, which are difficult to solve the problems of low utilization rate of irrigation water, serious waste of high-quality irrigation water and fertilizer resources, non-recyclable use of water and fertilizer resources, uneven distribution of water in the substrate space, and growth of flower seedlings. Restricted, low-quality commercial flowers, etc.
