Crop hydroponic device and hydroponic vegetable growing shed

Abstract

The invention discloses a crop hydroponic device and a hydroponic vegetable growing shed. The device comprises a hydroponic bed and a bed area floor. The hydroponic bed is located on the bed area floor. The bottom of the hydroponic bed is in direct contact with the bed area floor. One end of the hydroponic bed is connected with a water circulation intake mechanism. The other end of the hydroponic bed is connected with a water circulation reflux mechanism. The water circulation intake mechanism and the water circulation reflux mechanism are all communicated with a water collection bucket. A floating board for culturing crops is arranged in the hydroponic bed. The crop hydroponic device fully utilizes the soil temperature to adjust the temperature of the hydroponic bed, the oxygen content in the circulating water is high, no extra oxygen dissolution equipment is needed, the floating plate is more suitable for hydroponic bed, and the water level in the hydroponic bed can be effectively adjusted.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a crop hydroponic device and a hydroponic vegetable planting greenhouse. Background technique [0002] With the progress of society and the development of economy, the traditional agricultural vegetable planting method is ground soil planting, which gradually develops into greenhouse ground soil planting, and then further develops into greenhouse soilless cultivation planting, and now the greenhouse ground soilless cultivation As a new planting method, with the emergence of new planting methods, the representative vegetable substrate cultivation technology is among them. [0003] Vegetable matrix cultivation technology refers to a soilless cultivation method that uses a solid substrate to fix the plant root system and absorb nutrient solution and oxygen through the substrate. The solid substrate is fixed inside the round hole in the film. The vegetable substrate cultivation...

AI Technical Summary

Problems solved by technology

However, this kind of hydroponic bed has obvious defects: 1. The ground temperature cannot be fully utilized; 2. The circulation system needs to add dissolved oxygen equipment, which increases the cost, and the dissolved oxygen in the culture medium is relatively low, so the effect is average; 3. The structure of the seedling tray is single, the substrate is easy to leak from the cultivation hole and it is inconvenient to place the substrate, it is easy to stick to dust when placed on the ground, it cannot be used floating on the water surface and cannot be used in hydroponic technology; 4. The water level in the hydroponic bed It is a fixed height and cannot be flexibly adjusted according to the needs of different crops; 5. Crops are generally cultivated by film covering, which requires a harvester, and when planting, it is necessary to manually carry the seedling tray

[0005] At the same time, hydroponic planting needs to pay a large labor cost for seedling users to realize the management of hydroponic planting greenhouses, including operations such as seedling raising, fertilization, and irrigation, especially for seedling users with a large number of greenhouses. The workload is relatively large, which is not conducive to the promotion of hydroponic planting greenhouses
