Embodiment

[0049] Such as figure 1 , the present embodiment provides a soil cultivation experiment device 100 , including a cylinder body 110 , a transparent cover 150 , a funnel 120 and a support assembly 200 . One end of the barrel 110 is connected to the transparent cover 150, and the other end is connected to the funnel 120, and the three are placed on the support assembly. A support 180 is provided inside the barrel 110 , and a petri dish (not shown in the figure) for holding soil is placed on the support 180 ; a beaker 130 is placed below the funnel 120 .

[0050] Such as figure 1 , figure 2 with image 3 , the barrel 110 is cylindrical, made of opaque material, and includes a first end 111 and a second end 112 . An annular first groove 1141 is defined on the surface of the second end 112 of the barrel 110 , and a sealing ring 1143 is disposed at the bottom of the first groove 1141 . An annular second groove 1142 is also arranged on the outer side wall of the first groove 114...

Abstract

The invention provides a soil culture experimental device and belongs to the field of soil science and ecological resource environments. The device mainly comprises a cylinder, a transparent cover, a funnel and a supporting assembly. The transparent cover covers one end of the cylinder; the funnel is connected to the other end of the cylinder; and the device is supported by the supporting assembly. A beaker is arranged below the funnel, and a culture dish filled with soil is arranged in the cylinder. Water vapor volatilized from the soil in the culture dish is condensed into water drops on inner walls of the transparent cover and the cylinder so as to flow into the beaker. By changing the environment of the soil culture experimental device and monitoring emission of greenhouse gases in the device and change conditions of water amount in the beaker, necessary experimental data is provided for researching a relationship between the emission of greenhouse gases in the soil and the environmental condition change.

Description

technical field [0001] The invention relates to the fields of soil science and ecological resources and environment, in particular to a soil cultivation experimental device. Background technique [0002] As one of the most important biospheres on earth, soil is also the ecological carrier on which human beings depend. Scientific research on soil has important practical significance for the development of agriculture and the protection of ecological environment. [0003] In recent years, greenhouse cultivation technology has developed very rapidly. In seasons that are not suitable for plant growth, it can provide a growth period and increase production. It is mostly used for planting or raising seedlings of temperature-loving vegetables, flowers, forest trees and other plants in low-temperature seasons. The soil irrigation in the greenhouse is different from the outdoor soil irrigation. Researchers have invented many soil cultivation experimental devices to study and monitor...
