Abstract
The invention belongs to an analog system device used to detect crop rhizosphere respiration and mark plant in the agricultural production technical field. The invention, which improves the prior analog system device used to detect crop rhizosphere respiration and mark plant, consists of a PVC pot 2, a transparent outer box 3, a water tank 4, a gas sampling box 6, a sampling plug 7, an isolation pipe 9 and a gas injection plug 10; meanwhile, the invention improves detection precision and increases detection efficiency; moreover, during collecting soil respiration gas sample, the invention can complete <13> C mark on the aboveground part of crop, thereby integrating gas-collecting process and marking process; thus, the invention can finally obtain detection result of high precision to meet the requirements of scientific research better.
Description
Technical field
The invention belongs to field of agricultural production technologies.Be that a kind of detection crop rhizosphere is breathed and mark plant analog system device, can widespread use in atmosphere-crop-soil simulation system.
Technical background
A kind of detection crop rhizosphere is breathed and mark plant analog system device, is the fixedly CO in the atmosphere of modeling effort crop photosynthesis effect
2Distribution and rhizosphere respiration CO at crop plant, rhizosphere respiration
2The system and device that emission flux combines together.Its major function is that soil and atmosphere are separated.In the past, the mensuration of people's heavy soil respiratory rate is breathed attention inadequately to crop rhizosphere, and detection means falls behind, and error is big, and precision is low.Now, along with the progress of science and technology and the increase of atmosphere percent of greenhouse gases, people update the distribution research method and the means of crop photosynthesis product, and people recognize the importance that crop rhizosphere is breathed clear-headedly, and its decision crop is the CO in the atmosphere fixedly
2Again be discharged into ability in the atmosphere by rhizosphere respiration.So the researchist of greenhouse gases science both domestic and external aspect pays much attention to the research that crop rhizosphere is breathed.Rhizosphere respiration is as the fixing CO of crop photosynthesis effect
2, to atmospheric discharging CO
2The core component of process form focus and breach into the greenhouse gases research work, and it separates soil and relatively lags behind with the atmosphere interface method, few people study.
The general employing of traditional method is used less than the sampling box of basin alms bowl surface area at basin alms bowl soil face and is measured soil respiration, carries out mark with the transparent outer container that can't isolate soil and atmosphere interface, and disturbing factor is more in the measuring process, waste
13C-CO
2, error is big, make some less soil respiration differences detect less than, part is out in the cold.The present invention is exactly at above shortcoming, improve and perfect, take to isolate the sampling box of native face and atmosphere interface and crop plant can be placed the transparent outer container in the case that crop soil respiration is measured, and combine together with the crop plant labeling process, the data that detected soil respiration speed and marked product are distributed are accurate, precision improves, and is present the most feasible effective way.
Summary of the invention
The present invention is from above technical background, a kind of detection crop rhizosphere is breathed and mark plant analog system device improves and perfect, inhale the process of exhaling and combine together measuring soil, obtain soil respiration speed accurately and photosynthate distribution rule with the process of mark photosynthate.
Key of the present invention is that native face-atmosphere is all isolated and the crop plant mark and the external world are isolated simultaneously.We have finished the present invention through repeatedly test.The present invention is made up of basin alms bowl 2, transparent outer container 3, tank 4, gas sampling case 6, sampling plug 7, isolated tube 9 and gas injection plug 10.So just can combine together, finally obtain accurate data and information measuring the process of rhizosphere respiration and the process of mark plant,, thus better meet the scientific research needs.Concrete operation method is according to the following steps:
A. early-stage preparations: plant plant in the isolated tube 9;
B. sealing: tank is added 300ml distilled water for 4 li, and the base of sealing sampling box 6 is with the junction of 704 silica gel, 8 sealing sampling boxes 6 with isolated tube 9;
C. mixing: with the logical sampling box 6 tops sampling of 60ml syringe plug, twitch piston 3-4 time back and forth, with the interior gas of mixing sampling box 6;
D. gas production: get the vacuum glass bottle that 20ml gas injects 18ml with syringe;
E. detect: measure with gas chromatography;
F. transparent outer container: Open Side Down that cover is gone up crop plant transparent outer container 3, and end opening is put into tank 4;
G. add label: extract 50ml with the 60m syringe
13C-CO
2, the place is injected in the transparent outer container 3 at transparent outer container gas injection plug;
H. carry out mark: add
13C-CO
2After, spray transparent outer container 3 with tap water, reduce the temperature in the transparent outer container 3.
Accompanying drawing 1 explanation
