AI Technical Summary

Problems solved by technology

This method has complex operation steps and takes a long time to measure a sample
It is difficult to ensure the consistency of the results between the same sample and different repetitions. At the same time, multi-step acid-base titration reactions will also cause large errors in the results

Embodiment 1

[0035] Embodiment 1: as figure 1 Shown, the present invention is a kind of device for measuring fruit respiration rate, comprises airtight CO 2 Assimilation chamber 7 and photosynthesis measuring instrument 1, described photosynthesis measuring instrument 1 is provided with two CO 2 Detector, one end of inlet pipeline 2 and outlet pipeline 3 are respectively connected with CO 2 detector, the other end is connected to CO 2 The assimilation chamber 7 is fed with CO through the intake line 2 2 , when measuring, the fruit is placed in a closed CO 2 Assimilation chamber 7, CO 2 The variation of CO2 in the assimilation chamber 7 is the difference produced by fruit respiration.

[0036] The photosynthesis measuring instrument used in this example is PPsystems TPS-2 portable photosynthesis measuring system. Other models of photosynthesis measurement systems can also be used.

[0037] Such as figure 2 As shown, the CO 2 The assimilation chamber 7 is provided with a base 6 for...

Embodiment 2

[0067] Embodiment 2: the difference between this example and embodiment 1 is: the CO described in this example 2 The volume of the assimilation chamber is 1.7 times the volume of the fruit to be tested. The CO 2 The floor area of ​​the assimilation chamber is 1.6 times of the largest cross-section of the fruit to be tested. Such as image 3 As shown, in this example, a plurality of circular ventilation holes 10 are opened on the base 6, and ventilation holes of other shapes may also be used. Its assay method and measurement accuracy are identical with embodiment 1.

Embodiment 3

[0068] Embodiment 3: the difference between this example and embodiment 1 is: the CO described in this example 2 The volume of the assimilation chamber is twice the volume of the fruit to be tested. The CO 2 The floor area of ​​the assimilation chamber is 1.8 times of the largest cross-section of the fruit to be tested. Its assay method and measurement accuracy are identical with embodiment 1.

Abstract

The invention discloses a device and method for measuring the respiration rate of a fruit, and relates to the technical field of fruit respiration rate measurement. The device comprises a closed CO2 assimilation chamber and a photosynthesis tester, the photosynthesis tester is provided with two CO2 detectors, one end of a gas inlet pipeline and one end of a gas outlet pipeline are connected with the CO2 detectors respectively, the other end of the gas inlet pipeline and the other end of the gas outlet pipeline are communicated with the CO2 assimilation chamber, CO2 is introduced through the gas inlet pipeline, and during measurement, the fruit is placed in the closed CO2 assimilation chamber, and variation of CO2 in the CO2 assimilation chamber represents difference generated by the respiration of the fruit. The device is in a sealed state during measurement, and the measured data is accurate. A support is arranged under the assimilation chamber, so that the assimilation chamber can leave a test bed, the gas inlet pipeline and the gas outlet pipeline are connected to the bottom of the assimilation chamber, gas is introduced in the lower portion, and is mixed uniformly by a fan. Viathe method of the invention, the respiration rate of the fruit can be measured rapidly and accurately, and basis is provided for storage condition setting and further research of the fruits after harvesting.

Description

technical field [0001] The invention belongs to the technical field of measuring fruit respiration rate, in particular to a device and a measuring method for measuring fruit respiration rate. Background technique [0002] During the growing and maturing process of fruit and vegetable crops, timely picking and storage are carried out according to the degree of maturity. Depending on the storage environment and storage time, the maturity will change. When the fruit respiration peaks and the ethylene release is the largest , the maturity is the best, and the taste and quality of the fruit are the best; how to measure the respiration rate and ethylene release is very important to judge the maturity of the fruit, which is of great significance for the research of postharvest fruit storage. [0003] In addition, because fruit and vegetable crops have the characteristics of high water content, easy damage, many varieties, and easy to rot and deteriorate, they will usually be affect...
