安梨是富山果树的主栽品种。占辽宁省建平县富山街全街道果树总面积的50%左右,但产量极不稳定,开花较多,坐果较少,一般坐果率仅20%,稍有冻害就不足10%,所以安梨坐果率低是安梨产量低而不稳的原因。为探索提高安梨坐果率的途径,使安梨达到丰产、稳产的目的,我们在安梨花期进行不同浓度的硼肥试验,现将试验结果整理如下。 An pear is a major species of Toyama fruit trees. Accounting for about 50% of the total area of ​​fruit trees in the whole street of Fushan Street in Jianping County of Liaoning Province. However, the yield is extremely unstable with more flowering and less fruit set. Generally, the fruit set rate is only 20% and the frost damage is less than 10% The low yield is the reason for the low and unstable yield of pear. In order to explore ways to improve the pear fruit setting rate, so that the pear to achieve high yield, stable production purposes, we are in the pear flowering different concentrations of boron fertilizer test, the test results are summarized below.
