Automatic plant light and temperature device

Abstract

The invention discloses an automatic plant light and temperature device which comprises a soil heater, a temperature controller, a solar light supplementing lamp, a controller, temperature sensors anda power supply, and the controller is electrically connected with the power supply and the signal input end of the solar light supplementing lamp through control signal lines. The soil heater adoptsa geothermal wire for heating, the geothermal wire is circuitously pre-buried in soil, the temperature sensors are distributed in the soil on the upper portion of the geothermal wire, and the solar light supplementing lamp is erected on the upper portion of the soil in which the geothermal wire is pre-buried. Compared with the prior art, the automatic plant light and temperature device is suitablefor temperature control of plant root zone soil in greenhouse commercial crops, ground leaf light supplementation and auxiliary clearing of soil continuous cropping obstacles. The labor cost, the agricultural material cost and the management cost of crop production can be reduced, and the economic benefits are increased. Traditional agricultural production is modernized and intelligentized.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an automatic plant light temperature device. Background technique [0002] (1) Existing mainstream products [0003] At present, the existing intelligent supplementary lights and geothermal lines in the market only perform ground supplementary light and soil heating operations based on a single situation in actual use. Agricultural greenhouse planting production process. [0004] The main reasons for the combined operation of crop roots and leaves are: [0005] 1. Existing light supplement products can only supplement light on leaves. Although light can convert nutrients to plant cells, if the absorption of soil nutrients by the root system is ignored, the plants will shrink. Excess light can inhibit the growth of plant roots, because light can promote the formation of abscisic acid in roots, and too much light can also inhibit the growth of stems, converting free LAA to bound LAA. ...

AI Technical Summary

Problems solved by technology

[0006] 2. Existing soil heating products only focus on the increase of soil temperature in the underground part, and when the temperature exceeds the optimum temperature, the amount of nutrients absorbed will also decrease

The use cost is high, the operation technology is high, and it cannot be widely used

[0009] 2. There is also a geothermal product that only focuses on the temperature of the ground. This product cannot supplement the light on the leaves while increasing the soil.

Cannot automatically switch between the adjustment of soil temperature and leaf light
