Description
Technical Field
The application relates to the technical field of plant physiological parameter measurement, in particular to a system and a method for measuring physiological parameters of fruits and vegetables before circulation.
Background
After the fruits and vegetables are harvested, because the fruits and vegetables leave the parent bodies, the input of water, minerals and organic matters is stopped, and the fruits and vegetables need to breathe, consume the stored organic matters and release energy to maintain normal life activities. Meanwhile, after the fruits and vegetables are harvested, the accumulation of substances stops, the dry substances are not increased any more, and the substances in the fruits and vegetables are continuously transformed, so that the inherent color, fragrance, taste, texture and nutrient substances gradually reach the optimal use stage in the maturation process, and then the fruits and vegetables enter the aging process and are subjected to a series of quality deterioration. In addition, after the fruits and vegetables are harvested, water is easy to lose due to the transpiration effect, and the fruits and vegetables lose weight and are not fresh. Therefore, the strength of the comprehensive physiological actions of respiration, maturation and aging, transpiration and the like of the picked fruits and vegetables are closely related to the physiological and biochemical changes of the picked tissues of the fruits and vegetables and the storage life of the picked fruits and vegetables. Therefore, the monitoring of the physiological action of the picked fruits and vegetables to be detected becomes the core problem of fruit and vegetable storage.
The respiration rate, that is, the mass of carbon dioxide or oxygen absorbed per unit weight of plant body released per unit time is an index indicating how fast respiration proceeds, and a high respiration rate indicates that respiration is vigorous and that many respiratory substrates are consumed. Meanwhile, the ethylene release rate, namely the mass of ethylene released by a unit weight of plant body in a unit time, is an index for expressing the ripening and aging effects of fruits and vegetables. The transpiration rate, that is, the mass of water transpired per unit weight of plant body per unit time, is an index indicating the strength of transpiration.
