硼锌微肥对油橄榄花粉萌发及坐果的影响

The Effect of Micro-Fertilizer of Boron & Zinc on Pollen Germination,Fruit Bearing and Yield of Olive

田间试验结果表明:施用硼肥促进油橄榄花芽分化,花粉萌发率提高了74.1%,花期后的坐果率增加29.6%,产量增加14.0%;施用锌肥可以降低油橄榄硬核期和油脂形成期的落果率,分别降低18.5%和12.3%,产量增加12.1%;硼锌肥配合施用效果最佳,花粉萌发率提高了82.4%,花期后的坐果率提高了33.5%,硬核期和油脂形成期落果率分别降低了17.9%和14.8%,产量增加21.9%。

The filed trial on micro - fertilizer of boron ＆ zinc was made in olive garden. The result indicated： using micro -fertilizer of boron ＆ zinc could promote flower bud differentiation of olive and its pollen germination rate inceased by 74. 1% ,fruit bearing rate after bloom improved by 29.6% and yield added by 14.0% ;when adopted zinc fertilizer,its fruit falling rate in both stages of hard fruit stone and lipin formation reduced by 18.5% and I2.3% respectively and yield increased 12.1% ;the effect of combination boron ＆ zinc fertilizer was best and the germination rate of flower bud improved by 82.4% ,fruit bearing rate after bloom increased 33.5% ,yield added by 21.9 and the fruit falling rate in both stages of hard fruit stone and lipin formation reduced by17.9% and 14.8% respectively.
