栽培技术措施对盆栽神秘果开花结果及观赏效果的影响

Effects of Cultural Techniques on Fruit and Ornamental Effect of Potted Miracle Fruit (Synsepalum dulcificum Denill)

[目的]研究播种期、打顶处理、花盆大小对神秘果（Synsepalunduleific“mDenill）开花结果及观赏效果的影响，探索出能控制神秘果开花结果及提高其观赏价值的栽培技术。[方法]分别于2012年3月16日、4月16日、5月16E1采用穴盘播种育苗，有5—6片叶时上盆；花盆（高×宽）有3种规格，分别为230cm×200cm、260cm×220cm、280cm×240cm；分别在植株长到距离花盆口边缘往上3、5、7、9、11cm高时进行打顶处理。[结果]4月中旬是最佳播种时间，打顶有显著延迟开花的效果，距盆口高度3—5cm打顶的树形最优美，260cm×220cm规格的花盆与树体大小和谐，观赏效果最好。[结论]该研究可为提高神秘果盆栽效益提供技术支持。

[ Objective] The aim was to the influences on fruit and ornamental effect of miracle fruit caused by different sowing stage, topping treatments and pots sizes, to develop its cultural techniques to control blossoming and hearing fruits and improve ornamental effect. [ Method ] The seedlings were cultured by pot in March 16, April 16 and May 16, 2012, and they were transplanted when having 5 -6 leaves; the pot has three sizes, namely 230cm×200cm、260cm×220cm、280cm×240cm ; the tip pruning was carried out at the time when the height from the plant top to the pot edge was 3, 5, 7, 9, 11cm. [Result] The results show that April is the best sowing stage for miracle fruit in Guangxi, and different tip pruning lengths have significant regulation effects on blossoming and bearing fruits. Meanwhile, the most beautiful tree structures of miracle fruit are built by removing shoot apexes on the height of 3 - 5 cm from pots. Furthermore, the pot size of 260 cm × 220 cm is the best scale for planting miracle fruit. [ Conclusion] The study provides a technical support for improving pot culture effects of miracle fruit.
