Abstract

The invention relates to a carbon dioxide density automatic adjuster in seed cultivation, wherein it is formed by CO2 automatic fine discharger, CO2 density automatic online circulate detector, signal processing plate, controller and superior machine. The controller is the embedded system whose corn is C8051F005 single chip; the control software is programmed with MCS-51 language; the software of superior machine is programmed by VB6.0; the invention uses high-pure CO2 accurate discharge and CO2 density automatic tank internal circulate online detection, with high accuracy, to research the assimilate speed of seeds on CO2.

Description

1. Technical field [0001] The invention relates to an automatic control device for carbon dioxide concentration in the growth environment of large-scale tissue cultured seedlings, which belongs to the technical field of plant growth control and is specially used for the environment control of commercial production and large-scale production of tissue cultured seedlings. 2. Background technology [0002] Traditional seedling facilities and their environment hinder the commercial production and large-scale application of tissue culture seedlings. The use of large-scale seedling raising facilities and comprehensive environmental control engineering technology to organize factory-scale and large-scale production is an inevitable prerequisite for realizing tissue culture seedlings to become commercial products and widely used in agricultural production. The environmental control of facilities based on the growth process of tissue culture seedlings includes control requirements an...
