Greenhouse with cultivation of tide-type irrigation

Abstract

The invention discloses a greenhouse with cultivation of tide-type irrigation. Cultivation beds are arranged in the greenhouse and connected with a tide-type irrigation system. The greenhouse has the advantages that fertilizer liquid, a growth regulator and water completely circulates in a closed system, reflux liquid is completely recycled, water saving and high efficiency are achieved, 90% of water can be utilized, no water is drained, and a green and environment-friendly planting technique is achieved; the phenomenon that water films are generated on the plant leaf surfaces is avoided, leaves receive more illumination for photosynthesis, and more nutrients are absorbed from roots through transpiration pull; the relative humidity in air is easy to control, the leaf surfaces are kept dry, and the dosage of chemicals is decreased; coupled with computer control management, more precise irrigation can be achieved according to the plant growth conditions through control devices such as a temperature controller, a humidity detector and a soil detector, it is guaranteed that the plant growth speed is higher, the production efficiency is improved, the plant growth height is uniform, production standardization is achieved, the quality is guaranteed, and the cost is reduced; a steam disinfection device is arranged, therefore, the soil can be disinfected before crops are replaced, and occurrence of pest and disease damage is greatly reduced.

Description

technical field [0001] The invention relates to a greenhouse, in particular to a greenhouse combined with tidal irrigation technology. Background technique [0002] Greenhouse is the main facility of modern agriculture. It can adjust the light, shade, and is equipped with supporting facilities such as rainproof, windproof, cold-proof and modern agricultural technology facilities, so as to realize vegetable planting, fruit planting, flower cultivation and breeding in any season. and seed breeding, etc., but the current planting method in the greenhouse still adopts the method of spraying on the ground. First, the fertilizer solution, growth regulator, and water consumption are large; The photosynthesis of the leaves can easily cause the leaves and fruits to rot. The cultivation bed surface of the existing tidal irrigation cultivation technology adopts the impermeable plastic seedling tray molded. When irrigating, the seedling tray is filled with clear water or nutrient solu...

AI Technical Summary

Problems solved by technology

Although it overcomes some defects of the spray irrigation method, because the clear water or nutrient solution is directly exposed to the air in the pan, the evaporation is large, resulting in high air humidity in the greenhouse. If it is not collected and directly discharged into the local sewer pipe, it will cause Waste of nutrient solution also causes environmental pollution
