3个能源树种在上海地区的种苗繁育及物候反应

研究光皮树、山桐子、乌桕3个能源树种的种苗繁育技术及在上海地区的物候反应,为其在上海地区的推广种植提供科学依据。育苗试验采用种子地下20cm沙藏与自然保存2种处理方法,定期观察能源树种的物候反应。结果表明,经地下低温沙藏处理的3个能源树种的出苗率高于自然保存(对照),且出苗快、种苗生长整齐。其中,光皮树和乌桕的出苗率分别达82.6%和84.8%。3个能源树种在5月初～6月上旬开花,8～9月果实充实,10～11月底果实成熟,能适应上海地区气候和土壤条件。

Seedling Breeding of Three Species of Energy Trees and Its Phenology Reactions in Shanghai Area

The research aimed to study the seed breeding of the tree energy spaces and its,to provided technical basis of planting for energy tree.The seedling breeding techniques and the phenology reactions in Shanghai area of energy trees Swida wilsoniana,Idesia polycarpa and Sapium sebiferum were investigated.The seedling experiment was conducted both by burying seeds under 20 cm sand and by natural method(control) to observe the phenology reaction characters.The results showed that,in comparison with natural storage method,using the method of low temperature with burying under sand,the emergence rate of three energy species treated was higher,the emergence process was faster,and the seedling was neater.The germination rate of Swida wilsoniana and Sapium sebiferum were 82.6% and 84.8% respectively.The three energy trees bloomed during the beginning of May to the first ten-days of June,fruited fully in August to September,and the fruits matured during October to the end of November.The investigation indicated that the three energy trees could adapt to the climate and soil conditions in Shanghai area.
