Planting device for soilless culture of stevia rebaudiana

Abstract

The invention relates to the technical field of stevia rebaudiana planting, in particular to a planting device for soilless culture of stevia rebaudiana. According to the device, through joint cooperation of a mounted feeding hopper, a switching mechanism, a box body and a stirring assembly, a rotating handle is rotated to enable the stirring assembly to uniformly stir an added nutrient solution, meanwhile, a first belt wheel and a second belt wheel are driven to rotate, a liquid pump is started to pump the nutrient solution and convey the nutrient solution into a cultivation groove, an adjustable illumination structure is adjusted up and down, and an illumination lamp is driven to move up and down to illuminate stevia rebaudiana plants, so that photosynthesis of stevia rebaudiana is facilitated. A control motor drives an adjustable cultivation assembly to adjust the height, so that the roots of the stevia rebaudiana plants are in contact with the nutrient solution conveniently, and the upper parts of the plants are prevented from being soaked in the nutrient solution. When the nutrient solution needs to be replaced, a corresponding valve is switched on. The nutrient solution is discharged into a liquid discharging cavity through the switching mechanism, a liquid discharging valve is switched on to discharge the nutrient solution, cultivation personnel can replace the nutrient solution rapidly and conveniently, and growth of stevia rebaudiana plants is facilitated.

Description

technical field [0001] The invention relates to the technical field of stevia planting, in particular to a planting device for soilless cultivation of stevia. Background technique [0002] Stevia is a perennial herbaceous plant belonging to the family Asteraceae. Plant height 1-1.3 meters. Root shoot hypertrophy, 50-60, up to 25 cm long. The stem is erect, the base is lignified, the upper part is soft, densely covered with short hairs, the base of the corolla is light purple or white, and the upper part is white. Achene linear, slightly flattened, brown, with pappus. The flowering period is July-September, and the fruiting period is September-November. It is native to the alpine meadows on the border of Paraguay and Brazil in South America. Since 1977, it has been introduced and cultivated in Beijing, Hebei, Shaanxi, Jiangsu, Anhui, Fujian, Hunan, Yunnan and other places in China. [0003] This species likes to grow in a warm and humid environment and is sensitive to l...

Problems solved by technology

[0004] At present, the soilless cultivation device can plant three-dimensionally, save space, avoid pollution, save time and effort, save water and fertilizer, and is conducive to the growth of plants. Although the soilless cultivation device can realize the planting of plants, there are still some problems , when the soilless cultivation plant needs to replace the nutrient solution, it is time-consuming and laborious and cannot be replaced quickly. At the same time, it cannot provide sufficient light and cannot adjust the contact state of the stevia root with the nutrient solution according to the growth of stevia.
