| 中文摘要: |
| 本文探讨了缓释复合肥的养分释放特性，以及0g·m-2、50g·m-2、100g·m-2、150g·m-2、200g·m-2缓释复合肥施用量对莲雾插穗成活率、生根性状、叶片叶绿素含量和光合特性影响。结果表明，缓释复合肥的释放期达3个月，其氮、磷、钾养分的7d溶出率均低于15%，30d累计释放量低于80%。50g·m-2缓释复合肥用量处理对插穗生根数、根粗及生根量具有明显促进作用，100g·m-2用量处理可明显提高插穗的成活率、叶片叶绿素含量、净光合速率和蒸腾速率。缓释复合肥在莲雾种苗智能化快繁的应用上以50-100g·m-2为宜。 |
| 英文摘要: |
| The nutrient release characteristics of slow-release compound fertilizer (SRCF) was studied in this experiment. Meanwhile the effects of 0g·m-2,50g·m-2,100g·m-2,150g·m-2 and 200g·m-2 SRCF on survival ratio, rooting characteristics, chlorophyll contents and photosynthetic characteristics of Syzygium samarangense cuttings were studied. The results showed that the release period of SRCF was up to three month, whose 7-day nitrogen, phosphori and potassium nutrient preliminary solubility ratio was lower than 15%, while its 30-days nutrient cumulative release ratio was lower than 80%. The number,d iameter and weight of rooting were improved by treatment of 50g·m-2 SRCF, but the survival ratio, chlorophyll contents, transpiration rate(Tr) and net photosynthetic rate(Pn) of Syzygium samarangense cuttings increased obviously by treatment of 100g·m-2 SRCF. The appropriate usage of slow-release compound fertilizer was 50-100 g·m-2 of Syzygium samarangense cuttings in intelligent seedling fast cultivation greenhouse. |
