Description

Seedling raising device for energy-saving hydroponic vegetable planting Technical Field The invention relates to the technical field of vegetable seedling cultivation, in particular to an energy-saving seedling cultivation device for water planting vegetables. Background The hydroponic vegetables refer to a cultivation mode that vegetable roots grow in nutrient solution, and the hydroponic vegetables have the characteristics of short growth cycle and rich vitamins and minerals necessary for various human bodies; The water-saving type water planting vegetable seedling device capable of promoting rooting density has the application number 202210704710.7, and also solves the problem that the length of the root of the water planting vegetable in nutrient solution cannot be adjusted. According to the invention, the height adjusting mechanism is used for realizing that one half of vegetable root hairs are positioned in the nutrient solution; however, different vegetables have different rhizome ratios (1 a/1 b), as shown in fig. 1, and the roots of the hydroponic vegetables need to be half left in the nutrient solution, and the other half is exposed in the air, as shown in fig. 2, so that an optimal environment can be provided for the growth of the vegetables, the existing seedling raising device cannot flexibly and automatically adjust according to different types of hydroponic vegetables, and the height of the root system of the vegetables in the nutrient solution can be automatically adjusted by taking the weight of the nutrient solution as power and combining the varieties of the vegetables and the seedling raising period; meanwhile, the existing hydroponic vegetable seedling raising device cannot ensure that vegetables are in the same nutrient solution concentration, and the problem that hydroponic vegetables in the same batch are inconsistent in growth is easily caused, so that the energy-saving hydroponic vegetable seedling raising device is provided for planting the hydroponic vegetables. Disclosure of Invention The invention aims to provide an energy-saving seedling raising device for water-cultured vegetable planting, which can automatically adjust the height of a vegetable root system in a nutrient solution by taking the weight of the nutrient solution as power and combining the variety and seedling raising period of vegetables, and can ensure that the same batch of water-cultured vegetables grow consistently in the same nutrient solution concentration. In order to achieve the aim, the invention provides the technical scheme that the seedling raising device for energy-saving hydroponic vegetable planting comprises a hydroponic pond and a culture plate, wherein the hydroponic pond is arranged at the lower side of the culture plate, and culture holes for water-supply vegetable roots to pass through are formed in the culture plate; The seedling raising device further comprises a support column and a support plate, both sides of the Shui Peichi and the culture plate are in sliding connection with the outer sides of the support column through connecting lugs, sliding grooves are formed in the front ends of the water culture pond and the culture plate, sliding blocks are connected with the inner sides of the sliding grooves in a sliding manner, and the sliding blocks on the water culture pond and the front ends of the sliding blocks on the culture plate are rotationally connected with the same L-shaped plate through rotating shafts; the top end of the supporting plate is fixedly connected with a transverse plate, a plurality of transverse through holes are formed in the inner sides of the transverse plate and the L-shaped plate, the through holes on the transverse plate correspond to the through holes on the L-shaped plate in the initial position, the rotating column is inserted into one of the transverse through holes, and the rotating column is simultaneously positioned in the through holes on the transverse plate and the through holes on the L-shaped plate; Under the initial position, L template can rotate with the pillar as the center, and when the water planting pond descends, the culture plate can rise relatively, and when the position of pillar can change the water planting pond and descend under the initial position through changing, the rising range of culture plate for match the water planting vegetables of different rhizome ratios. Under the above arrangement, the invention can automatically and reasonably adjust the height of the root system of the vegetable in the nutrient solution by taking the weight of the nutrient solution as the power and combining with the variety and seedling period of the vegetable, in the invention, the L-shaped plate can rotate by taking the rotary column as the center at the initial position, the two ends of the L-shaped plate form a lever mechanism by taking the rotary column as the center, when the water culture pond descends, the culture plate can relatively ascend
