Embodiment 1
[0055] Embodiment 1. An indoor soil cultivation device integrating ventilation cultivation and gas collection
[0056] An indoor soil cultivation device integrating aeration cultivation and gas collection, the structure is as follows: figure 1 , 2 , 3, including the culture container 9, the top opening of the culture container 9 is fixedly provided with a partition 8 matching the top opening, the partition 8 includes a partition body and a gas opening and closing device, and the top opening is airtightly and fixedly connected on the partition The ventilation container 6 is provided with a vent 10 on the side wall of the ventilation container 6, and a top cover 5 is buckled on the ventilation container, and the top cover 5 is provided with an air inlet 4 and an air sampling hole 17, and an air intake pipe is fixed in the air inlet 4 2. One end of the air intake pipe 2 is inserted into the culture container, and the other end is connected with an air intake three-way valve 3. T...
Embodiment 2
[0063] A method utilizing the device of embodiment 1 to carry out soil cultivation and gas collection, comprising soil aeration cultivation, airtight cultivation, gas collection, the steps are as follows:
[0064] (1) Soil aeration culture
[0065] Unplug the top cover, put the prepared soil sample into the culture container, cover the top cover, open the gas opening and closing device, lift the top cover upwards, expose the vent on the side wall of the ventilation container, and adjust the gas collection tee at the same time Valve and air intake three-way valve to realize free ventilation inside and outside the culture container for aerobic culture. Weigh and record the total weight of the soil sample and the culture device before culture. During the culture process, use the gravimetric method to replenish the water lost due to evaporation every 2-4 days , Use a syringe with a long and thin needle to supplement distilled water into the culture container through a three-way va...
