Three-dimensional automatic rotating seedling-cultivating frame and seedling-cultivating method thereof

Abstract

The invention relates to a three-dimensional automatic rotating seedling-cultivating frame and a seedling-cultivating method thereof and belongs to the technical field of agricultural production. The three-dimensional automatic rotating seedling-cultivating frame comprises a rack, bearing bases, a speed reduction motor, a driving shaft, rotating arms, four-rod balancing mechanisms, seedling-cultivating trays, floating trays and an electric cabinet, wherein the bearing bases are mounted at the two ends of the rack; the driving shaft is arranged on the bearing bases; one end of the driving shaft is connected with the speed reduction motor through a gear; the rotating arms are mounted at the two ends of the driving shaft; the four-rod balancing mechanisms are mounted at the two ends of the rotating arms; the seedling-cultivating trays are hung at the two ends of the four-rod balancing mechanisms; the floating trays are arranged in the seedling-cultivating trays; and the electric cabinet is mounted on the rack. The three-dimensional automatic rotating seedling-cultivating frame can set the four control parameters of temperature, humidity, illumination and time according to the requirements of seedling cultivation; the speed reduction motor is controlled to drive the rotating arms to rotate; and the seedling-cultivating trays are driven to horizontally rotate slowly by the four-rod balancing mechanisms on the rotating arms, and the floating seedlings can be uniformly irradiated by sunlight, so that the usage rate of the land is increased.

Description

technical field [0001] The invention relates to the technical field of floating seedling raising equipment, in particular to a three-dimensional automatic rotary seedling raising frame and a seedling raising method thereof. Background technique [0002] Floating seedlings is a widely used technology in agricultural production. The basic procedure is to plant the seeds of crops in a floating seedling tray made of plastic foam with multiple seed planting holes, and place the seedling tray in a container filled with nutrients. In the liquid seedling pond, let the seedling tray float on the water surface, the substrate in the planting hole absorbs the nutrient solution for the seeds to germinate and grow, and then transplant the seedlings to the field after they grow up. At present, this method of raising seedlings is restricted by the lighting requirements of plants, and most of them are carried out in a single layer on one piece of land, occupying a large area of ​​land.

Problems solved by technology

[0003] The name of the invention is a three-dimensional seedling stand with balanced lighting, the application publication number is CN104094831A, and the application number is 2014103222526. It discloses a tobacco seedling raising tray that uses a cylinder to push the seedling raising tray horizontally out of the three-dimensional rack to receive sunlight and is controlled by a timing device. , its shortcoming is that the cylinder can only push out one layer of seedling trays to receive sunlight each time, and other multi-layer seedling trays still cannot receive sunlight, and the time for tobacco seedlings to receive sunlight is insufficient and uneven, the structure is complicated, and the manufacturing cost is high. The power consumption is large, which is not conducive to popularization in actual production; the name of the invention is a multi-layer seedling raising frame, the application publication number is CN104705108A, and the application number is 201310667641.8. The cost of turning the seedlings is improved and the quality of the tobacco seedlings is improved, saving space. The disadvantages are that no automatic control method is adopted, no time control requirements are set, the time for the tobacco seedlings to receive irradiation is not equal, the sunlight is not uniform, and the growth of the tobacco seedlings is not good.

[0004] In the growth process of tobacco seedlings, in addition to nutrients being necessary growth factors, lighting conditions are also important factors related to the growth of tobacco seedlings. In the existing technology, the adjustment of the acceptance time of tobacco seedlings is basically achieved by using the set time value, although in a certain To a certain extent, it satisfies the conditions for the tobacco seedlings to receive light, but there are the following technical problems. Under the conditions of unsuitable light conditions and temperature conditions, the effect of using the cylinder to push the seedling tray horizontally out of the three-dimensional frame to receive sunlight is not good, and it is wasteful. Electric energy; the efficiency of photosynthesis of tobacco seedlings is different under different temperature and humidity conditions, and the growth of tobacco seedlings needs to provide a reasonable temperature and humidity range value in order to achieve the best photosynthesis
