This paper renewed the research progress of almond biology , summarized and analyzed the current status of polarization , pollination and fructifications . suggestions were put forward on further research directions 摘要阐述了近年来扁桃生殖生理研究的新进展，就扁桃的花芽分化、开花授粉、坐果等方面的研究现状进行了总结和分析；提出了今后扁桃生殖生理研究的方向和建议。
Cleft graft of hard branch of those varieties used " gongniang no . 1 " as stocks showed low affinity of stock and scion , rooting rate , plant percent , bloom percent and yield in a productive garden , 3 ~ 4 year - old graft trees showed low fruit while full bloom , 5 ~ 6 year - old graft trees showed a large mount of death 上述品种与“公酿一号”硬枝嫁接、表现接穗与砧木亲和力差、生根和成苗率低、生产建园开花株率和产量低、 3 ~ 4年生树嫁接树出现满树开花坐果少、 5 ~ 6年生树出现大量死亡。
Rare earth among them improves orange shan face to face fruit weight , the fruit quality effect are maximal , gush the shi rare earth comparing with to spraying water , citrus 24 . 66 improve 14 . 44g , fruit strengthens the shape thing improving 1 . 15 percentage points , fruit and fruit weight ratio valve re - high 0 . 036 ; boron is best to raise citrus fruit , citrus fruit sprayed borax 1 . 71 percentage points higher than spraying water 其中喷施稀土对提高柑桔单果重、果实品质作用最大，与喷施清水比较，柑桔单果重提高14 . 44g ，果实固形物提高1 . 15个百分点，果瓣重与果重的比值高0 . 036 ；喷施硼砂对提高柑桔坐果率效果最好，比喷施清水高1 . 71个百分点。
