Experimental leaf vegetable water culture device

Abstract

The invention discloses an experimental leaf vegetable water culture device, and belongs to devices for vegetable culture. The experimental leaf vegetable water culture device comprises a nutrient solution tank, a colonization plate, colonization cups and a circulating device, wherein the nutrient solution tank is of a box body structure, an opening is formed in the upper end of the box body structure, the colonization plate is matched with the opening in the upper end of the nutrient solution tank in shape and arranged in the opening in the upper end of the nutrient solution tank, a plurality of colonization holes are evenly distributed in the colonization plate, the area of an opening in the upper end of each colonization hole is smaller than that of an opening in the lower end of the corresponding colonization hole, the thickness of the position, at each colonization hole, of the colonization plate is at least two centimeters, the number of the colonization cups is more than one, the colonization cups are arranged in the nutrient solution tank below the colonization holes and correspond to the colonization holes respectively, an air outlet of the circulating device is formed in the nutrient solution tank, and an air inlet of the circulating device is communicated with air outside the nutrient solution tank. According to the experimental leaf vegetable water culture device, the root systems of vegetables can be immersed in a nutrient solution partially, and cannot be completely immersed in the nutrient solution, it is ensured that plants sufficiently absorb nutrients, sufficient oxygen can be provided for the root systems of the plants, and the contradiction between nutrient absorption and oxygen absorption in the process of traditional water culture of seedlings is solved.

Description

technical field [0001] The invention relates to the field of devices for cultivating vegetables, in particular to a hydroponic device for experimental leafy vegetables. Background technique [0002] In the research work of vegetable cultivation, researchers usually need to regulate the content and ratio of mineral nutrients in vegetables. However, when traditional soil cultivation is carried out, the content and form of mineral elements in the soil and the pH value of the soil are difficult to control. This poses a serious challenge to researchers when exploring the fertilizer requirements of vegetable crops. On the other hand, when the fertilizer experiment conducted for a specific soil is extended to another area with a different soil environment, it needs to be readjusted, which has great limitations in promotion. [0003] At present, vegetable hydroponics can be used to cultivate vegetables. Vegetable hydroponics refers to direct contact between the root system of vege...
