摘要
筛选出适合苹果梨喷施的叶面肥,为苹果梨高产优质栽培奠定基础。通过设计叶面肥配方,在生长期喷施,研究8个叶面肥配方对苹果梨叶片百叶重、叶绿素含量、果实产量和品质的影响。结果表明,8个叶面肥处理后叶片百叶重、叶绿素a含量、叶绿素b含量、总叶绿素含量均比对照高;叶面肥处理均增加了单株产量;喷施叶面肥后,果实硬度有所降低;果实可溶性固形物含量、可溶性糖含量有所增加;对可滴定酸含量影响不大,大部分处理提高了果实糖酸比和果实中维生素C含量;综合效果以配方③(磷酸二氢钾0.3%,硫酸镁0.2%,硫酸铜0.02%,EDTA-Fe 0.02%,硫酸锰0.05%,硫酸锌0.10%,硼砂0.15%)最好。
The suitable leaf fertilizer of Pingguoli was studied in order to provide a theoretical basis for high-yield and high-quality cultivation of Pingguoli.By designing the leaf fertilizer formula and spraying it in the growing period,the effects of 8 leaf fertilizer formulas on leaf weight,chlorophyll a,chlorophyll b,total chlorophyll content,yield and fruit quality of Pingguoli were studied.The results showed that the leaf weight,chlorophyll a,chlorophyll b,and total chlorophyll contents after 8 foliar fertilizer treatments were higher than those of the control;foliar fertilizer treatments increased the yield per plant;spraying foliar fertilizer reduced fruit firmness,increased soluble solids content,and increased soluble sugar content.The effect on titratable acid content was not obvious.Most treatments increased the sugar-acid ratio and vitamin C content;the comprehensive effect was the best with formula③.
