Detail
需要充足光照
喜光照充足,注意剪除干枯枝、病老虫枝以及过密的细弱枝,保持株型并加强植株内部的通风透光。根浅且枝条脆弱,不耐强风以免影响植株生长甚至减产

喜湿润也较耐旱
喜湿润也较耐旱,原产地区呈现明显的干湿交替气候,年雨量在500-1000mm,常有干热风。忌积水,雨季需注意排水防涝

18~28℃
适温18~28℃,喜高温而不耐寒,适宜年均温度为20~28℃,抗寒力因品种不同而异:抗寒品种可耐-6℃低温,抗寒力低的品种遇0℃低温则干枯

对土壤适应性较强
对土壤适应性较强,常散生在非洲稀树草原瘦薄的砖红壤和砾土中。喜土层深厚、疏松肥沃且排水良好的壤土。在钙质土或氧含量低的土壤上,最有效的方法是将螫合铁溶液注入根区

果期前后均需追肥
每年常规应用氮肥4次以上,当某土壤或灌溉水中有氮时,用氮量应相应减少。成年树幼果期施有机肥每株50kg,复合肥50g,采收后再施一次且施肥量加倍
