Problems solved by technology
On the one hand, the stem flow meter is expensive. On the other hand, the stem flow meter is mostly used to measure the stem flow rate of outdoor plants. Because outdoor plants are greatly affected by the environment and have a high transpiration rate, it is easy to measure. For cut flowers in indoor or control rooms, In addition, the water absorption capacity of the root system is lost, the transpiration rate is low, and the sap flow meter is difficult to measure accurately; moreover, the operation process of the sap flow meter test is relatively cumbersome and requires high requirements for the operator

Embodiment Construction
[0029] see figure 2 Shown, the system of the present invention is by balance (being weighing device) 1, triangular flask 2, water tank 3, hose 4, computer 5, and balance is the balance that can set measurement interval time, and can be connected to computer, triangular flask 2 and the water tank 3 are filled with distilled water 6 respectively, and are respectively placed on a balance. The bottle mouth of the triangular bottle 2 is tightly sealed by a silicone plug 7 with a round hole, and fresh cut flowers 8 are inserted into the round hole, and its flower stem is connected to the triangular bottle. The gap between the hole walls of the bottle 2 is filled with Vaseline material, and the fresh cut flowers 8 are inserted into the triangular bottle 2 through the round hole of the silicone plug 7. The highest liquid level of distilled water is higher than the highest liquid level of triangular flask distilled water, and the top of the water tank 3 is sealed by a cover 9 (or adop...

The invention provides a system for detecting the moisture absorption, the moisture losses and the change of fresh weight of cut flowers, which is used for the scientific research and teaching of fresh flowers and comprises at least two scales (weighing device), a triangular flask, a water channel and a hose, wherein the triangular flask and the water channel with the distilled water or preservation solution are respectively arranged on the scales, the triangular flask is communicated with the water channel by the hose, and the scale is connected with a computer. When measuring, the scales are connected with the computer, and the distilled water or preservation solution is accommodated in the triangular flask and the water channel, the cut flowers are inserted in the triangular flask from a circular hole above a silicone stopper, and the triangular flask is filled with the distilled water or preservation solution in the measuring process, so that the decreased amount of the solution in the water channel is the absorptive amount of the cut flower; then the triangular flask and the water channel are slowly moved to the scales, the scale is connected with the computer by pressing the print key, and thus the change of fresh weight of the cut flower is measured by the scale. The system of the invention is easy to manufacture, can realize automatic successive reading and automatic recording, and has the advantages of high measurement precision, low work load, high test efficiency and wide market prospect.
Description
technical field [0001] The invention relates to a measuring device, more particularly to an automatic detection system and method for water balance and fresh weight change of fresh cut flowers. Background technique [0002] The water balance of fresh cut flowers refers to the maintenance of a good state among the water absorption, transportation, transpiration and water holding capacity of flower branch tissues of cut flowers. The freshness and saturation of fresh-cut flowers depend on the balance between water absorption rate and transpiration rate. When the balance is disrupted, the transpiration rate is greater than the water absorption rate, causing water stress and eventually leading to the wilting and senescence of cut flowers. Water transport status is a key factor to maintain the water balance of cut flowers and prolong the life of cut flowers. Therefore, the role of water transport rate of cut flowers in the water balance of cut flowers has attracted much attention...
