Research On The Introduction And Cultivation Test And Industrialization Of Passiflora Caerulea In The Mountains In Southwestern Zhejiang

The dissertation analyzes the ecological adaptation of Passiflora Caerulea in the mountains in southwestern Zhejiang and explores its feasibility of introduction there and industrialization development combined with actual conditions and characteristics of Lishui City, by growing "Tainong No.1" in Lishui, Zhejiang—the hybrid of yellow and purple fruits of Passiflora Caerulea introduced from Guangxi Province and observing the physical and meteorological phenomena, and through introduction test and data analysis thus comes to the following conclusions:1 .The test of introduction and meteorological observation of Passiflora Caerulea in the mountains in southwestern Zhejiang: "Tainong No. 1" has a wide range of temperature adaptation. Generally it can be grown under the average annual temperature around 20℃in frost-free or frostless areas. The test shows that under the monthly average temperature around 25 ~ 30℃Passiflora Caerulea grows fast while below 16℃it almost stops growing. It cannot grow normally under the temperature below 8℃and can be injured by frost and low temperature below 0℃. Passiflora Caerulea requires highly on water and must have sufficient water supply through its growing period. According to the observation by Luo Handeng, drought can restrain the growth and the plant will wither under high temperature and drought. Leaves will roll up and flowers and fruits will fall down and fruits shrink, which will affect both yield and quality. Even worse, the plant will wither and die. If water is excessive, causing soil water, it will lead to root rot, stem swelling, leaves fall off easily, thus increasing stem rot and leaf and fruit diseases.Passiflora Caerulea is the plant requesting long sunshine with Photoperiod effect. Long sunshine can promote budding and flowering. Zhang Yusen in Taiwan thinks that the plant only buds under a boundary of temperature and in extreme temperature it can not bud, and in appropriate temperature, temperature affects more greatly than light. Through the observation of this experiment, it shows that the light conditions in the mountains in southwestern Zhejiang can meet the requirements of budding and flowering. "Tainong No.1" survived in Lishui and the next year it bore fruits.2.The test of introduction and physical observation of Passiflora Caerulea in the mountains in southwestern Zhejiang: "Tainong No.1" in Lishui grows fast under the monthly average temperature around 25～30℃and below 16℃it almost stops growing. It cannot grow normally under the temperature below 8℃and can be injured by frost and low temperature below 0℃. In 2007 "Tainong No.1" was planted in Lishui, the next year it flowered and bore fruits. In late May buds appeared and it only needed about 28d from budding to flowering, and it took about 60～80d for fruits to get ripe. The fruit-picking period is from early August to early December and the main fruit production period is from August to October and from October to December.3.Research on industrialization of passiflora caerulea in the mountains in southwestern Zhejiang: Through observation on introduction and ecological adaptability, it comes to the conclusions that introduction of passiflora caerulea in the mountains in southwestern Zhejiang is feasible. Combined with the actual conditions in the mountains in southwestern Zhejiang, the dissertation analyzes the advantages of industrialization development, and proposes some ideas and measures of development.
