Description

A kind of portable accommodating case for determining greenhouse gases

Technical field

The utility model is related to agricultural sources greenhouse gases field of measuring technique, and in particular to a kind of measure greenhouse gases Portable accommodating case.

Background technology

Closed chamber method be study agricultural sources greenhouse gases important method, but in measurement process seal time length to determine The influence of result is different, and seal time is short, and gas emissions are small, and evaluated error is big；Seal time is long, Hygrothermograph gas in case The influence of bulk concentration is also bigger, and difference under natural conditions is also bigger.The one of the main reasons for causing difference be determine when by Personnel are determined in crop growth period to be limited by tools for measurement, need syringe needle to penetrate the glue taken on casing on stomata when gas is taken in case Plug, syringe needle connects triple valve simultaneously, and gaseous sample is transferred to after syringe, it is necessary to switching three-way valve, will wherein connect and take gas in case , then be transferred to gas in syringe in airbag by one section of venthole UNICOM of bag, that is, complete once to take gas.Period is planted due to field In the case that the influence of strain growth and airbag have constant weight, scene takes gas and often obtains at least two people's co-ordinations, Cai Nengshun Profit completes to take gas.Can otherwise delay and most preferably take the gas time (morning 8-9 points), take gas variation of ambient temperature and differ greatly.

Numerous studies show, closed chamber method is the important method for studying agricultural sources greenhouse gases, no matter in paddy field, nonirrigated farmland also It is meadow, is all used widely, it is larger by actual link and ambient influnence due to taking gas process then in practical operation, Often sample time is long：

1. testing program typically requires morning 8-9 points for optimal sample time, and one cannot operate during sampling, is needed during sampling Three aspects are taken into account, a syringe needle connection triple valve for insertion static chamber plug a, needs constantly take the syringe of gas, and one is The sampling bag of triple valve is connected, people sampling is often turned round and look to come over, around two people coordinate that the sampler space is limited and easily trample on Plant；

2. need on the one hand to observe and record temperature data when sampling, also need to arrange sampling material after on the one hand sampling, Next operation can be just carried out after all sampling bag is put into.When often there is determining next sample, there are thermometer or pin Pipe falls in a upper sampled point；

3. new hand is not easy to grasp when employing people to sample, the factor such as sample room error is larger；

4. sampling equipment is not standardized, disunity, often in the presence of in actual sampling process, syringe rate of air sucked in required and speed and It is input into the time bad control of airbag；

5. 3 points of control simultaneously is needed in sampling process, that is, connects the syringe needle of static chamber, the syringe and gas of reformed gas Metal sampler bag, during easily cause the syringe needle bending for connecting plug to damage, syringe departs from triple valve and sampling bag in gravity Effect is lower to be departed from triple valve or damages syringe needle；

6., it is necessary to oneself take polybag or cloth bag by the materials such as thermometer, syringe needle and airbag one after a sample is taken One arrangement is kept well, can just carry out next experiment point sampling, bag container excessively random and plastic containing bag rapid wear.
