After fresh fruits and vegetables are harvested, they will still undergo respiration, and different species and sizes of fruits and vegetables will have different respiration. Since respiration has an important impact on the storage of fruits and vegetables, in order to reduce losses, improve fruits and vegetables. The storage tolerance and storage quality of fruits requires the use of fruit and vegetable respiration recorders to measure and study the respiration intensity of fruits and vegetables, to grasp the postharvest physiological state of fruits and vegetables and their changing rules, and to further develop reasonable storage effects for fruits and vegetables. Storage plan.
The index for measuring the respiration of fruits and vegetables is the respiratory intensity, which refers to the amount of carbon dioxide (milligrams or milliliters) released by fruits and vegetables per kilogram of fresh fruit within one hour, or the amount of oxygen absorbed (milliliter or milliliter). The number) is in units of CO2ml・h・kg. In order to accurately determine the respiratory intensity of fruits and vegetables, and then determine the respiratory strength of fruits and vegetables to provide scientific basis for agricultural scientific research, storage of fruits and vegetables, etc., modern widely used measuring instruments for measuring fruit and vegetable respiration recorder. The instrument is a professional instrument for measuring the respiratory intensity of fruits and vegetables. It is versatile, high-precision, fast, efficient, and convenient. It is very suitable for various types of fruits, gardens, fruits, vegetables, foreign trade and other schools and research institutes. Respiration measurement of vegetables.
The post-harvest respiration of fruits and vegetables has a negative and beneficial effect on the storage of fruits and vegetables. On the downside, the respiration of fruits and vegetables not only consumes large amounts of stored nutrients but also accelerates aging. Heat energy will shorten the storage period of fruits and vegetables, and promote the deterioration of quality and death of tissues and fruits. On the positive side, the respiration of fruits and vegetables has a positive effect on both the wound healing and disease resistance, so that the fruits and vegetables are still a living living body after harvesting, and it is the post-harvest storage of fruits and vegetables. Therefore, the application of fruit and vegetable respiration recorder to master the post-harvest physiological changes of fruits and vegetables is an important basis to eliminate the adverse effects of respiration and improve the beneficial effects of respiration. It is of great significance for controlling storage conditions and improving the storage quality of fruits and vegetables.
