Description

Technical Field

[0001] The utility model relates to the technical field of hydroponic cultivation, and in particular to a hydroponic plant cultivation system. Background Art

[0002] Hydroponic cultivation is a type of soilless cultivation. Hydroponic cultivation is the planting of hydroponic plants in cultivation facilities. The nutrient solution is used to provide the plants with the nutrients they need for growth. Compared with traditional soil cultivation, hydroponic cultivation has the characteristics of fast plant growth, high water and fertilizer utilization rate, low heavy metal residue, no risk of repeated cropping, and low pesticide application. Therefore, the product safety of hydroponic vegetables is higher than that of traditional cultivated vegetables. The nutrient solution of hydroponic cultivation is adjustable, easy to control, and measurable. It not only saves water and fertilizer, but also can produce some functional products by adding some flavor products or raw materials to increase the added value of the products. Therefore, hydroponic vegetables are generally regarded as an emerging safe production method and are used in production. On the market side, more and more restaurants, supermarkets and consumers are beginning to accept hydroponic vegetables. Hydroponic vegetables are used in sandwiches, hamburgers, salad vegetables and hot pot vegetables. Although there is a strong demand for hydroponic products on the production and market sides, hydroponic cultivation started relatively late in China and there is relatively little research. Currently used hydroponic products are either imported from abroad or locally produced. However, the cost of foreign system equipment is relatively high, resulting in huge initial investment and cannot adapt to modern agricultural production. Domestic equipment often has a low degree of mechanization and is difficult to adapt to factory-based and large-scale modern agricultural production.

[0003] At present, there are mainly the following types of cultivation systems used for hydroponic plant production in China: one is the deep liquid flow cultivation system, which has serious moss and low dissolved oxygen content in the nutrient solution, which can easily cause poor plant growth; one is the shallow liquid flow cultivation system, which is highly labor-dependent, and is inconsistent with the trend of industrial development under the trend of aging population and the continuous decrease in the number of farmers; one is the shallow liquid flow pipeline cultivation system, which is prone to problems such as clogging of cultivation holes and difficulty in cleaning, and generally has a high automation cost; there are also some track-type cultivation modes, which can be connected to automation, but there are still some technical details that need customer service. Therefore, the industry urgently needs a type of hydroponic cultivation system that requires less labor, labor-saving operation, and can be connected to mechanization and automation.

[0004] For example, the Chinese patent application number is CN201620244766.9, and the application date is March 28, 2016. The patent document discloses a panoramic hydroponic device, including a long strip culture tank, a water inlet pipe is arranged at the bottom of one end of the culture tank, an overflow pipe is arranged at the other end of the culture tank, the mouth of the overflow pipe is lower than the top of the culture tank, and a plurality of floating plates floating side by side are arranged in the culture tank, and a plurality of cultivation holes for cultivating plants are arranged on the floating plates.

[0005] For example, the Chinese patent application number is: CN202022008839.3, and the application date is: September 11, 2020. The patent document discloses a cultivation rack that facilitates light and water and fertilizer supply, including: a main bracket, transverse brackets are arranged on both sides of the main bracket, and a cultivation device is installed between the transverse brackets; the cultivation device includes a cultivation pot, a lifting pot, a sliding assembly and an irrigation and fertilization assembly, a lifting pot is arranged in the cultivation pot, sliding assemblies are arranged on both sides of the cultivation pot, the sliding assembly is docked with the transverse bracket, and the irrigation and fertilization assembly is arranged at the lower end of the cultivation pot; the irrigation and fertilization assembly includes a fertilizer pipe, a watering pipe, a telescopic connecting pipe, a water connecting pipe and a material pipe.

[0006] Both of the above schemes belong to hydroponic cultivation devices, but both have shortcomings. For example, the nutrient solution is easily affected by environmental factors and deteriorates during transportation, and the cultivation efficiency is not high enough. The cultivation of hydroponic vegetables relies more on manual placement of vegetable storage materials in predetermined locations, which is not labor-saving enough and cannot expand planting.
