摘要
【目的】研究配方施肥对库尔勒香梨果实品质及叶片矿质营养含量的影响,以15、16生库尔勒香梨树为材料,分别进行1年、2年配方施肥处理,分析配方施肥不同年限处理对香梨果实品质及叶片矿质营养含量变化的影响。【方法】香梨树秋季开沟进行配方施肥。所用肥料为羊粪,生物黑炭,粒状重过磷酸钙,硫酸钾按,尿素按,微量元素,配方施肥1年、2年果实成熟期分别取样。【结果】配方施肥能提高果实中VC含量和还原糖的含量,降低果实中的总酸含量及果实的硬度,改善果实品质;配方施肥处理能提高叶片营养元素的含量,其中配方施肥2年效果明显。各处理之间有着显著差异,施肥效应表现为:配方2>配方3>配方1>CK。【结论】配方施肥2年配方2处理效果最好。
[ Objective ] In order to research the effects of mineral nutrition content on fruit quality and leaves of Korla Fragrant Pear with formulated fertilization, the author takes 15 and 16 years Korla Fragrant Pear as research objects, and respectively does formulate fertilization treatment in a year and two to study the effects of different years of treatment formulated fertilization on the fruits of Korla Fragrant Pear. [ Method ] Digging the ditch under the fragrant pear tree in autumn and then spreading fertilizer, The materials of the fertilization included： sheep excrement; biological black carbon; granular triple super phosphate; potassium sulfate; urea; trace elements; Sampling the mature fruits after one yearg fertilization and two years＇fertilization. [ Results] The result showed that formulated fertilization could improve the contents of vitamin C and soluble sugar, reduce the contents of total acid and fruit firmness to improve the Korla Fragrant Pear quality, which fi- nally proved that the effects of two years＇formulation was obvious. The founding is that significant differences existed between different treatments, and the order of formulated fertilization effects was as follows ： Formulated fertilization 3 〉 Formulated fertilization 2 〉 Formulated fertilization 1 〉 CK. [ Conclusion ] Effects of two years＇formulation Formulated fertilization 2 are the best.
