摘　　要：[目的]利用多肽能够促进作物吸收矿质营养的特点,将其施用在青花梨上,用以改善青花梨品质并提高耐贮性。[方法]以青花梨为试验材料,采用叶面喷施多肽结合地面施用石灰对青花梨进行处理。[结果]多肽处理B(每株施石灰1 kg+1 000倍多肽叶面喷施)和处理A(每株施石灰1 kg+800倍多肽叶面喷施)与对照相比,可溶性固形物含量分别提高了15.9%和13.6%;可滴定酸含量分别下降了17.4%和8.7%;果实硬度分别增加了16.0%和9.6%。贮藏至第9天,多肽处理B和处理A与对照相比,好果率分别提高了30%和27%。[结论]施用多肽对于改善青花梨的果实品质和贮藏特性有明显效果,对于青花梨的生产销售具有重要意义。[Objective] The quality and storability of Qinghua pear（Pyrus pyrifolia Nakai）was improved by means of the application of peptide due to its ability in the promotion of the absorption of mineral nutrition.[Method] The Qinghua pear being taken as the testing material,the peptide as foliar was sprayed in combination with application of lime treatment on ground around the pear plant.[Results] It was expected to use peptides to promote absorption of mineral nutrition and calcium elements in order to improve the quality and storability of Qinghua pear.The content of soluble solid,the titratable acid and fruit firmness of the treatment B（the foliar application of 1 000 times＇ polypeptide and 1 kg lime per plant） and the treatment A（the foliar application of 800 times＇ polypeptide and 1 kg lime per plant） was 15.9% and 13.6% more than,17.4% and 8.7% lower than and 16.0% and 9.6% harder than that of the CK,respectively.The rate of good fruit of treatment B and treatment A on the 9th day of storage was 30% and 27% more than that of the CK.[Conclusion] The application of polypeptide could effectively improve the quality and storability of Qinghua pear,which was significant in its production and sale.
