以9年生黄冠梨为试材,研究在梨果实采收前45天土施硼、钾肥对黄冠梨果实品质的影响。结果表明,株施硼砂0.375 kg、株施硼砂0.250 kg+硫酸钾0.5 kg,黄冠梨的平均单果重显著高于不施肥树;株施硼砂0.375 kg+硫酸钾1.0 kg处理黄冠梨的果实硬度显著高于不施肥树;单施硼肥、单施钾肥和硼钾肥配合施用处理黄冠梨果实可溶性固形物含量与对照无显著差异;单施硼肥、单施钾肥和硼钾肥配合施用处理黄冠梨果实总糖含量均显著高于不施肥树;株施硫酸钾1.5 kg处理黄冠梨的果实总糖含量显著高于3个单施硼肥处理和株施硼砂0.250 kg+硫酸钾1.5 kg处理;不施肥树的果实糖酸比显著高于多数施用硼、钾肥处理。
The experiment was conducted to study the effects of boron and potassium fertilizers on the fruit quality of Huangguang Pear 45 days before pear harvest. The results showed that the average fruit weight of Huangguan pear was significantly higher than that of no-fertilization tree when 0.375 kg of borax was applied, 0.250 kg of borax was applied and 0.5 kg of potassium sulfate was applied. The hardness of Huangguan pear with 0.375 kg of borax and 1.0 kg of potassium sulfate was significant Higher than the non-fertilization trees; Soluble solids content of Huangguan pear with single application of boron fertilizer, single application of potassium fertilizer and boron-potassium fertilizer had no significant difference with that of the control; Single application of boron fertilizer, single application of potassium fertilizer and boron- The total sugar content of pear fruits was significantly higher than that of the non-fertilized trees. The total sugar content of the plants treated with 1.5 kg potassium sulfate was significantly higher than that of three single application of boron fertilizers and 0.250 kg of potassium borax and 1.5 kg of potassium sulfate. The fruit sugar acid ratio of non-fertilizing tree was significantly higher than that of most applying boron and potassium fertilizer.
