The Flowering Phenology And Development Utilization Of Countermeasures Of Hedychium Panzhuum

Hedychium panzhuum is a common herbaceous plant in sichuan,it is characterized by its elegant appearance,fragrant aroma and long flowering period.This study is based on a wild plate of Hedychium panzhuum,According the main content such as flowering of individual and group dynamics,the flowering periods of community,pollination insects,pollination behavior and the preservation of fresh flowers,and it is designed to provide a theoretical basis for the essential properties and development of the flowers.It is shown that:?1?The Flowering of phenology:the results shows that the flowering span of colony is late July to early October.The flowering duration is about 77 days,and the flowering duration of inflorescence is12 to 25 days.The duration of single flower viewing is 2³ days.The flower of the single plant has the regularity of the ascending order,and the flowering period is roughly the parabolic change,and the blooming peak is about 5d after the beginning,and the peak period is 7⁸d,and the curve is wavy after reaching the peak.The number of flowering from 8:00 to 18:00 is a single peak curve,which is almost non-flowering over this time period.In the process of flowering,there are dynamic changes in the position of the filament and the flower column,presenting an Angle of about 120¹70 degrees.?2?There are 8 species of visiting insects,including 5 eyes and 8 families.Among them,according to the frequency of visiting flowers,the main visiting insects are Bombus sp.and Papilio xuthus.According to the average length of visits,Papilio xuthus is three times that of Bombus sp.,but the frequency of the visits,Bombus sp.is three times that of Papilio xuthus.The daily activity pattern of the two is unimodal and bimodal.The peak flowering date of Papilio xuthusis at 10:00-12:00,which is belong to unimodal and Bombus sp.is at 11:00-12:00 and 12:00-14:00 which is belong to bimodal.In rainy and cloudy weather,the number of visitors to the flower is relative small,between 1 and 4.?3?preservation of fresh cut flowers:10.0mg/mL Ca²⁺+500mL distilled water+3g sucrose+0.5g salt+1.0ml alcohol+1.0ml vinegar+1/4 vitamin C fresh liquid can significantly prolong the life of the ginger flower;It significantly increases the fresh weight of ginger,increases its water absorption and enhances the water retention.Delay the activity of POD activity of the ginger flower,thereby delaying the senescence of ginger flower.It helps to increase the amount of soluble sugar in the petals of the ginger flower,and to reduce the amount of soluble sugar.?4?The development strategy:the beaded ginger plant is large,and can be planted in the flower beds;Flower shaped like a butterfly,can be used as fresh cut flowers;The flower can be extracted with essential oil for cosmetics and so on;Its rhizome can be medicine and edible;It is a herbaceous plant with a strong tillering ability.In the case of seed reproduction relatively difficult,it is possible to first adopt the subplant or dig into the underground tuber of the field to reproduce.
