Below, in conjunction with specific embodiments and accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 is that greenhouse gas emission influences the structural representation of the Culture basin alms bowl in the experimental provision to plant described in the utility model to soil;
Fig. 2 is the synoptic diagram of the state of overlooking of Culture basin alms bowl shown in Figure 1;
Fig. 3 is that greenhouse gas emission influences the cross-sectional view of experimental provision to plant described in the utility model to soil.
Embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, greenhouse gas emission influences experimental provision and is made up of Culture basin alms bowl 1, gas collecting case 2 and soil moisture feed system plant provided by the utility model to soil, and this soil moisture feed system is made of tank 5, vitrified-clay pipe 3 and silicone rubber tube 4.
Culture basin alms bowl 1 is the circular alms bowl by the PVC material, and height and diameter are decided according to the quantity of actual load soil, highly is 20cm generally, diameter 15cm.On the sidewall of Culture basin alms bowl 1 bottom, offer a circular hole 11, its size just can be held the silicone rubber tube 4 that connects vitrified-clay pipe 3, in order to prevent that air from entering soil by the slit, be preferably between the circular hole of being offered on the sidewall of silicone rubber tube 4 and Culture basin alms bowl 1 bottom 11 and seal with 704 glue.Culture basin alms bowl 1 top outer rim is equipped with the holding groove 12 of gas collecting case 2, and as can be seen, the profile of holding groove 12 is a square, length of side 25cm, high 5cm from Fig. 1 and Fig. 2.The PVC that the central authorities of Culture basin alms bowl 1 are fixed with for the plant growth isolates pipe 13, internal diameter 2.5cm, high 6cm, wherein the part of PVC isolation pipe 13 is stretched out on Culture basin alms bowl face, another part stretches within the Culture basin alms bowl, in the present embodiment, the 2.5cm that this PVC isolates pipe 13 partly stretches out on Culture basin alms bowl face, and remaining 3.5cm partly stretches within the Culture basin alms bowl.This PVC isolates pipe 13 usefulness PVC bars 14 and is connected with Culture basin alms bowl 1 edge, plays fixation.During sowing, seed is directly broadcast at PVC and is isolated in the pipe 13, makes the plant 6 that grows be in PVC and isolates among the pipe 13.
By the soil moisture feed system that tank 5, vitrified-clay pipe 3 and silicone rubber tube 4 constitute, its vitrified-clay pipe 3 is connected with silicone rubber tube 4, is connected with tank 5 after the circular hole 11 that silicone rubber tube 4 is offered on the sidewall that passes Culture basin alms bowl 1 bottom.The length of tank 5 is 90cm, wide 20cm, and high 30cm, a tank 5 can be connected with a plurality of Culture basin alms bowls 1 simultaneously.The water yield in the tank 5 is in time replenished according to the variation of tank water level by the full automatic water supply system.
During concrete the use, at first fills with water in tank 5 provides water to soil in time in right amount by silicone rubber tube 4 and vitrified-clay pipe 3.During sampling, in the holding groove 12 of Culture basin alms bowl 1, add suitable quantity of water, mention gas collecting case 2, instigated air 20 seconds with fan, ventilate, then gas collecting case 2 is put into the holding groove 12 that water is housed, gas collecting case 2 is submerged in the water all around, the exchange of air and outside air in the isolated gas collecting case 2 is isolated pipe 13 seam crossings with 704 glue sealing gas vasculums 2 with the PVC that grows for plant simultaneously.After all seal operation are finished, begin with clinical syringe needles by high elasticity silica rubber plug 24 sample gas in the gaseous sample collection hole 22, simultaneously with the temperature in the thermometer 25 record gas collecting casees 2.Gather sample then at set intervals one time, obtain several required samples.After sample collecting finishes, gas collecting case 2 is upwards mentioned, staggered being placed on the holding groove 12 of about 45 degree is beneficial to the circulation of air at ordinary times.
Advantage of the present utility model:
1, effectively got rid of the impact of plant self greenhouse gas emission;
2, sampling is convenient, easy to implement;
3, be specially adapted to research to the greenhouse gas emission diurnal variation law;
4, the process that keeps the skin wet can not exert an influence to the soil air composition, and soil moisture is in whole reality simultaneously Test and remain on a stable range in the process.
