Anthurium is the most important ornamental crop in the genus Araceae. It is native to tropical regions such as Central and South America. It prefers to grow in a shaded environment with high temperature and humidity. It is vulnerable to chilling below 10°C; relative humidity is 80 ~90% is better. In order to further improve the quality of Anthurium cut flowers and reduce the unstable factors of market supply quality, it is necessary to strengthen the post-harvest processing of flowers and the transportation of refrigerated trucks. The following describes the post-harvest treatment process and the conditions for cutting red flowers. Post-harvest treatment Maturity and time of harvesting The cutting of red palms in the fleshy inflorescence begins at the base with up to 1/2 to 2/3 color change, and the spathes are flattened and brightly colored, which is the appropriate maturity for harvesting. Should avoid the harvest at hot noon, due to the higher temperature will advance the aging of red cut flowers. Harvested Anthurium cut flowers should be in the morning or evening when temperatures are low, and should be placed in a cool place after harvest to slow their breathing rate. Can be directly extracted from the base by hand, and then cut obliquely at the base of the flower stem with a knife, because this part is less water-absorbent, and can reduce the chance of bacterial infection by the mother plant, and due to the large size of the flaming leaf, strong evapotranspiration, water loss rate Fast, cut flowers should be directly inserted in clean water to avoid loss of water. Red-handed cut flowers can also be harvested by knife cutting. After harvesting 3 to 5 sticks, the insert should be sterilized in a solution with a concentration of 70% alcohol for 1 minute or more to reduce the infection of pathogenic bacteria between the mother plants. The current practice is to spare several knives and sterilizing barrels. Disinfect the knife immediately after use and use another knife for rotation instead. Soak enough time in the disinfectant solution to reduce the bacterial infection. The field water-absorbing bactericidal flower field-preparation solution preferably uses tap water because chlorine in the tap water has a bactericidal effect, which can reduce the growth of the red-handed cut flower at the incision site due to bacterial infection and block the growth of metabolites, thereby impeding the absorption of water. In order to increase the bactericidal effect, 50 ppm sodium hypochlorite can be added to the preliminary solution, and the water quality should be adjusted to be slightly acidic to reduce the growth of pathogens. Washing and pre-cooling Due to the high temperature during harvesting, the consumption of cut flower nutrients will be caused and the flowers will be dehydrated. Therefore, after harvesting, the field must be quickly removed, placed in a cool place, and treated with pre-measuring solution. On the other hand, if there are too many falling dusts in the flames of red-handed flowers, it will affect the appearance. It needs to be rinsed with clean water, and it must be filled with water when it is cleaned and dried. It should be dried under natural ventilation to avoid sunlight exposure. The hard-burning spath of the red palm is easy to cause mechanical damage during harvesting or cleaning, causing brown-black creases during storage and transportation. Therefore, mechanical damage should be avoided during harvesting and cleaning. In addition to the pre-treatment measures for field watering, they should be returned to the packing yard as soon as possible and the flower should be inserted into the preservative for at least 4 hours to increase the vase life of cutting red flowers. The pre-cooling method can be divided into vacuum pre-cooling and pre-cooling with strong wind. Today, most flower growers in Taiwan make use of cold pre-cooling of refrigerators. The pre-cooling temperature is 15°C to 18°C, and the required time is at least 4 hours to achieve the effect of pre-cooling. . Graded packaging China's current industry standards for the Ministry of Agriculture will cut red flowers into three levels. First-class product requirements: pure varieties, excellent overall feeling, no defects; flaming leaf-shaped large, complete, bright color, smooth, no variegated spots, scorpion transverse stem: ≥12 cm; bright inflorescence bright; flower葶 葶 Straight, solid and tough, thick, uniform thickness, length: ≥ 40 cm. Second-grade product requirements: pure varieties, good overall feeling, basically no defects; large, complete, bright color, no variegated spots; Straight, solid and tough, thick, uniform thickness, length: ≥ 30 cm. The requirements for the three grades are pure varieties, good overall feeling and slight defects; the spathes are small in shape and relatively complete; the bracts are basically free of variegated spots; the bracts are transverse stems: ≥ 7 cm; the inflorescences of the panicles are bright and relatively intact; Calyx slightly curved, weaker, uneven thickness, length: ≥ 30 cm. When the flowers are packaged, the bags must be bagged and protected. After the package is completed, the flowers are inserted into a 50 ppm sodium hypochlorite preservation solution, and the flowers are cut into boxes according to the species, quality, flower diameter, and pedicel length of the red palm flower cut. Do not overlap more than one-third of the flower surface, and it is better to have the stems neatly discharged to the side. The middle of the flower stems is taped to the surface of the box to avoid pressure cracks. Refrigerated transport After cutting, packing, and packing, Anthurium cut flowers should be moved into the refrigerator for cooling. The refrigerating temperature is 15°C to 18°C. When transported to the flower wholesale market, the flower transport vehicle used shall be an air-conditioned refrigerated truck or insulated transport vehicle to maintain the low temperature and keep fresh. Avoid the use of general trucks to transport, so as to avoid the evapotranspiration and respiration of flowers caused by instantaneous temperature rise, or due to the weather and sun and rain, resulting in poor quality or loss of cut flowers.
