杏果营养丰富,但坐果率低,导致产量不高,影响了杏树的发展。杏树坐果率低的主要原因有:一是不完全花比例高,完不成正常授粉受精过程;二是花期和幼果期易受低温冻害;三是营养物质积累少,花芽分化质量差。因此,要想提高杏树坐果率,增加产量,应采取以下几项措施:1品种选择和配置应
Apricot nutrition is rich, but the fruit setting rate is low, resulting in low yield, affecting the development of apricot. The main reasons for the low fruit setting rate of almond trees are as follows: First, the proportion of incomplete flower is high, and the process of pollination and fertilization is not completed; the second is that the flowering and young fruit are susceptible to low temperature frost damage; the third is the less nutrient accumulation and the poor quality of flower bud differentiation. Therefore, in order to improve apricot fruit setting rate and increase production, the following measures should be taken: 1 Selection and allocation of varieties should be
