Device for automatically controlling temperature and humidity of rice seedling raising plate

Abstract

The invention provides a device for automatically controlling temperature and humidity of a rice seedling raising plate. The seedling raising plate has a structure as follows: a seedling raising substrate is filled into a trough type seedling raising plate, an electric heating film is arranged at the lower part of the seedling raising substrate, and a drip irrigation pipe is arranged at the middle part of the seedling raising substrate; one end of the drip irrigation pipe is connected with a water pump; a water inlet end of the water pump is connected with a water diversion pipe; and a humidity sensor and a temperature sensor are embedded into the seedling raising substrate. A controller has a structure as follows: a single chip microcomputer is arranged in the controller; a humidity display and a temperature display are arranged on a panel of the controller; a humidity setting button is arranged at the lower part of the humidity display; a temperature setting button is arranged at the lower part of the temperature display; and the controller is provided with a power switch. A sensor and a controller interface are arranged on the controller respectively. By virtue of a control method, control on the temperature and the humidity of the seedling raising plate is achieved. The device provided by the invention can achieve adjustment and control of the temperature and the humidity of the seedling raising plate, and ensure normal growth and development of rice seedlings. The device is suitable to be taken as an application of the device for automatically controlling the temperature and humidity of the rice seedling raising plate.

Description

technical field [0001] The invention provides a control device in the field of agriculture, in particular an automatic control device for the temperature and humidity of a seedling raising tray. Background technique [0002] At present, seedling raising trays are usually used for seedling raising. The seedling raising trays vary in size, so the seedling raising area is uncertain. When the seedling raising area is large enough, it is difficult to control the temperature and humidity of the seedling raising, so it is easy to cause the seedlings to grow unevenly, and even some seedlings It cannot be used, because the seedlings are uneven, which will affect the plants after planting, affect the normal growth and development of the seedlings, and even cause the reduction of yield and quality. Contents of the invention [0003] In order to overcome the shortcomings that the existing seedling raising trays cannot automatically control the temperature and humidity, the present inv...
