Description

High-position cultivation device for greenhouse

Technical Field

The invention relates to the technical field of greenhouses, in particular to a high-position cultivation device for a greenhouse.

Background

Greenhouse is also called warm house. Can transmit light, keep warm (or heat), and is used for cultivating plants. In seasons unsuitable for plant growth, the method can provide the growth period of the greenhouse and increase the yield, and is mainly used for cultivating or raising seedlings of plants like warm vegetables, flowers and trees in low-temperature seasons. The greenhouse has a plurality of types, which can be divided into a plurality of types according to different roof truss materials, lighting materials, shapes, heating conditions and the like, for example, the high-level cultivation device for the greenhouse disclosed by the publication No. CN106063429B, when the hanging rope is wound or unwound, the lifting of the hanging rope is guided by the rotation of the pulley, so that the center of the lower end of the hanging rope can be maintained even if the length of the hanging rope is variable, thereby stably lifting the cultivation box, thereby having the advantage of conveniently realizing the stable lifting management of the cultivation box, and the pulley, the support U-shaped hook and the support hook are assembled, so that the pulley, the support U-shaped hook and the support hook can be partially replaced when being worn, thus, there is an advantage that it is economically effective, and the lower end of the hanging rope is combined with the pulley to reduce the friction force generated when the hanging rope descends, so there is an advantage that the life of the hanging rope can be extended; for another example, the tidal irrigation cultivation greenhouse disclosed in publication number CN105993709A can be a green and environment-friendly planting technology, in which fertilizer solution, growth regulator and water are completely circulated in a closed system, return solution is completely recycled, water is saved and high efficiency is achieved, 90% of utilization can be achieved, and no discharge is generated; secondly, water films are prevented from being generated on the surfaces of the plant leaves, so that the leaves receive more light to perform photosynthesis, and transpiration tension is promoted to absorb more nutrient elements from the roots; thirdly, the relative humidity in the air is easy to control, the leaf surface is kept dry, and the use amount of chemical drugs is reduced; fourth, supplementary with computer control management, through controlling means such as temperature controller, moisture detector, soil detection appearance, can realize more accurate irrigation according to vegetation situation, guarantee that vegetation speed improves production efficiency faster, and vegetation height is unified realizes production standardization, guarantees quality, reduce cost. Fifthly, a steam disinfection device is arranged, and soil can be disinfected before crops are transplanted, so that the occurrence of plant diseases and insect pests is greatly reduced; for example, the soilless culture device for the greenhouse disclosed in the publication No. CN108391585A, the cultivation plate is supported by the support plate by placing the cultivation plate on the support plate, and the support plate is supported by the support plate, and the support plate is pressed by the pressing block by the elastic force of the third spring, so that the stability of the cultivation plate is ensured, and the cultivation plate is always in a stable state when the water tank is changed, thereby avoiding the problems that the sponge is unstable and damages are easily caused to plants when the water tank drains water because the sponge is not fixed in the soilless culture box, and thus, the existing high-level cultivation device for the greenhouse can meet the use requirements of people, but still has the following problems.

Current high-order cultivation device for warmhouse booth is when installing the hasp, because high-order cultivation device need be with a plurality of cultivation basins dispersion at the height of difference, and the shower nozzle on big-arch shelter top is when irrigating the shower nozzle, and the seedling of growing seedlings of lower part is easily blockked to the upper portion to lead to the irrigation of growing seedlings not enough even, and prolonged the growth cycle of growing seedlings down, consequently need for a neotype high-order cultivation device for warmhouse booth to solve above-mentioned problem urgently.
