以9年生M26矮化中间砧红富士苹果为试材,研究套餐肥、控释肥对红富士叶片大小、质量、光合速率、果实产量及品质的影响。结果表明:施用套餐肥使叶片显著增大,叶色浓绿,叶面积、百叶鲜重、百叶干重分别较对照增加3.5%、5.2%、3.0%,产量提高幅度达10.9%,果实硬度和可溶性固形物含量增加,总酸含量降低;施用控释型肥增产5.5%,果实硬度、可溶性固形物含量和总酸含量增加。
The effects of package fertilizer and controlled release fertilizer on the leaf size, quality, photosynthetic rate, fruit yield and quality of Red Fuji were studied using 9-year-old M26 dwarfing red Fuji apple. The results showed that the foliar application of fertilizer increased significantly, the leaf color dark green, the area of leaf, the fresh weight of leaf and the dry weight of leaf increased 3.5%, 5.2% and 3.0% respectively, and the yield increased by 10.9% Soluble solid content increased, total acid content decreased; application of controlled release fertilizer yield 5.5%, fruit firmness, soluble solids content and total acid content increased.
