Intelligent LED (Light-Emitting Diode) light supplementing automatic control device for seedling raising in tobacco curing greenhouse

Abstract

The invention discloses an intelligent LED (Light-Emitting Diode) light supplementing automatic control device for seedling raising in a tobacco curing greenhouse, which belongs to the field of automatic agriculture planting. According to the adopted technical scheme, a seedling raising pond bracket is arranged in a tobacco curing and seedling raising greenhouse, and is provided with an upper layer seedling raising pond and a lower layer seedling raising pond; LED light tubes are fixed on the lower part of the upper layer seedling raising pond; a wireless signal receiver is connected with an LED lamplight controller; and a remote controller and a wireless signal emitter are arranged outside the seedling raising greenhouse. The intelligent LED light supplementing automatic control device is set specific to different illumination requirement characteristics at tobacco seedling growing periods, so that different requirements of tobacco seedlings on illumination at different growing periods are met, the quality of tobacco seedlings is enhanced, and the subsequent transplanting survival rate of tobacco seedlings is increased; due to the design of the upper and lower layers of seedling raising ponds, the space utilization ratio of a seedling raising shed is increased; the LED light tubes are controlled wirelessly to supplement light for tobacco seedlings, so that the developing speed of tobacco seedlings is increased; and the intelligent LED light supplementing automatic control device has the advantages of advanced design concept, practical function and attractive and reasonable layout.

Description

technical field [0001] The invention relates to an intelligent LED supplementary light control device for greenhouse seedling cultivation, in particular to an intelligent LED supplementary light automatic control device for flue-cured tobacco greenhouse seedling cultivation, which belongs to the field of automatic agricultural plant planting. . Background technique [0002] Light is the only source of energy for photosynthesis of tobacco seedlings. The intensity and stability of light directly affect the whole process of growth and development of tobacco seedlings. The normal growth and development of tobacco seedlings depends on sunlight, but the light time is short in late autumn, winter and spring When the energy is insufficient, the photosynthesis of tobacco seedlings is hindered, the growth is slow, and the development of mechanical tissues is poor. Weather, rain and snow will also bring serious consequences to the growth of tobacco seedlings. The lighting environment...

Problems solved by technology

[0004] Although the current natural lighting greenhouse seedling cultivation has made great progress compared with open-air natural seedling cultivation, it still cannot achieve the ideal lighting effect because it is still directly affected by natural light; It is to sow the seeds on the mother bed first, and when the tobacco seedlings grow to the cat ear stage, put the tobacco seedlings into the nutrition bag of the child bed, and transplant them to the field after they grow into seedlings

The root system of the tobacco seedlings raised by this method is developed, the seedlings grow quickly, and the survival rate is high, but this method not only has low space utilization, but also has complicated seedling raising procedures and high costs
