Soilless vegetable culture greenhouse water economizer

Abstract

The invention discloses a soilless vegetable culture greenhouse water economizer. The soilless vegetable culture greenhouse water economizer comprises a greenhouse body, the bottom of the greenhouse body is provided with a greenhouse foundation which is arranged on both sides of the top of a concrete layer, and the bottom of the concrete layer is provided with a thermal insulating layer; the innertop of the greenhouse body is provided with a steel structure triangular fixing frame, the bottom of the steel structure triangular fixing frame is provided with a beam and a plurality of support plates, wherein the beam is arranged in the middle of the bottom of the steel structure triangular fixing frame, the support plates are uniformly arranged on both sides of the beam, the bottom of the beam is provided with a sliding rail which is matched with a slider, and the bottom of the slider is provided with a hanging loop; corresponding culture stands are arranged between the support plates andthe concrete layer, and every culture stand is sequentially provided with a culture groove I, a culture groove II and a culture groove III, and a water spray device I is arranged above the culture groove I. The soilless vegetable culture greenhouse water economizer has the advantage of being high in efficiency and saving labor and material resources.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a water-saving device for a soilless vegetable greenhouse. Background technique [0002] Soilless cultivation refers to the cultivation method that does not use natural soil but uses substrate or only substrate when growing seedlings, and irrigates with nutrient solution after planting. Since soilless cultivation can artificially create a good rhizosphere environment instead of soil environment, it can effectively control Soil continuous cropping diseases and physiological obstacles caused by soil salt accumulation fully meet the needs of crops for mineral nutrition, water, gas and other environmental conditions. Therefore, they are widely used in the field of greenhouse vegetable cultivation, but the demand for water in traditional vegetable greenhouses is very high Large, but without water-saving facilities, the waste of water and fertilizer is serious, and the utilization rate is lo...

[0002] Soilless cultivation refers to the cultivation method that does not use natural soil but uses substrate or only substrate when growing seedlings, and irrigates with nutrient solution after planting. Since soilless cultivation can artificially create a good rhizosphere environment instead of soil environment, it can effectively control Soil continuous cropping diseases and physiological obstacles caused by soil salt accumulation fully meet the needs of crops for mineral nutrition, water, gas and other environmental conditions. Therefore, they are widely used in the field of greenhouse vegetable cultivation, but the demand for water in traditional vegetable greenhouses is very high Large, but no water-saving facilities, so that the waste of water, fertilizer, etc. is low, and the utilization rate is low. At the same time, the space inside the greenhouse is not enough, making the transportation of materials very cumbersome
