Soilless cultivation device

Abstract

The invention discloses a soilless cultivation device. A support frame body comprises two support frameworks which are arranged relatively; each support framework is formed by splicing hollow stainless steel pipes and is connected by a plurality of conveying pipes which are parallel to each other; each support framework is provided with a set of circulation power device; two chains on the two support frameworks are connected together by a plurality of connecting rod distributed on the chains along the length directions of the chains; the conveying pipe located at the topmost is distributed with a plurality of spray heads; and a delivery outlet of a pumping device is connected to the support frameworks. By using the soilless cultivation device, each loading plate is ensured to have an equal spraying opportunity, so that the consistency of growth conditions of crops in all the loading plates is ensured; and when a culture solution is required to be replaced, the culture solution used for a relatively long time in each loading plate can be flushed by the pumping device by a regulating device and the spray heads, a new culture solution is replenished, and only the starting / stopping of the pumping device and the rotation of a chain wheel are required to be controlled in the whole replacement process.

Description

technical field [0001] The invention relates to a soilless cultivation device, which belongs to the field of agricultural planting. Background technique [0002] In the process of agricultural development, soilless cultivation is an emerging technology, because with the continuous development of urbanization, agricultural land becomes less and less, and soil has gradually become a scarce resource. In the case of soil as a carrier, more and more researches have been done to supply nutrients to crops and ensure the normal growth of crops. At present, soilless cultivation is mainly to place the crops in the culture solution on the planting frame, and regularly light and replenish water according to the growth needs of the crops. However, since the support is divided into multiple layers, it is difficult to ensure the uniformity of light and water supply. As a result, the growth of crops in various regions is inconsistent, and after the crops grow for a period of time, there wi...

At present, soilless cultivation is mainly to place the crops in the culture solution on the planting frame, and regularly light and replenish water according to the growth needs of the crops. However, since the support is divided into multiple layers, it is difficult to ensure the uniformity of light and water supply. As a result, the growth of crops in various regions is inconsistent, and after the crops grow for a period of time, there will be too many impurities in the culture solution, and new culture solution needs to be replaced regularly, and the replacement of the culture solution under each crop requires a lot of work. , low work efficiency and inconvenient management
