Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the specific embodiment of the patent of the present invention is described.

[0017] A closed device for the study of the gas release and gas conversion laws of plants, mainly composed of a plant growth chamber 1, a gas pipeline 2, a gas cooling chamber 3, a liquid collector 4, a circulating water pump 5, a gas analyzer 6, and a lighting system 7 components, characterized in that: the growth space of plants is completely sealed, and the cultivation conditions such as light, temperature and humidity, wind speed, and water irrigation can be reasonably regulated according to experimental needs.

[0018] The plant growth room 1 of the designed airtight device is a cylinder with a diameter of 30 cm and a height of 100 cm. The upper and lower layers are tightly connected with flanges. The inner diameter of the ventilation pipe 2 is 8 mm and the length is 40 cm. The gas cooling room 3 adopts a cylindrical design with an inner dia...

Abstract

The invention relates to a closed device for carrying out researches of gas release and gas reforming rule of plants, which mainly consists of a plant growth chamber 1, a gas pipe 2, a gas cooling chamber 3, a liquid header 4, a circulating pump 5, a gas analyzer 6 and an illumination system 7; the closed device is characterized in that growing space of plants is completely closed, and cultivation conditions of illumination, temperature and humidity, wind velocity, water irrigation, and the like, can be properly adjusted and controlled according to experiment needs. The closed device for carrying out researches of gas release and gas reforming rule of plants has the beneficial effects of good tightness, strong external interference resistance, adjustable conditions of illumination, temperature, humidity, wind velocity, water irrigation, and the like, and being beneficial to researches of the gas release and gas reforming rule of plants under the closed condition. The closed device of the invention can be used for the researches of the closed systems such as space stations and space permanent bases, and the like, as well as the plant gas research fields of ground greenhouse and air purification, etc.

Description

technical field [0001] The invention relates to an airtight device for plant gas research, which is particularly suitable for the research on the gas release and gas conversion laws of plants. Background technique [0002] Plants play a very important role in nature, absorbing CO 2 , provide O 2 , and at the same time release some trace gases. The good growth of plants is inseparable from light, temperature, humidity, air, water, nutrition and other conditions. Under open conditions, it is difficult to test the gas release and gas conversion of plants, and it is difficult to meet the environmental conditions under airtight conditions. The existing airtight devices for the study of plant gas release and gas conversion laws under airtight conditions exist. The disadvantages of uncontrollable cultivation conditions such as light intensity, temperature and humidity, and wind speed. Contents of the invention [0003] The invention relates to an airtight device for the study...
