对莱阳梨主产区土壤进行专题调查,并进行土壤、植株和果品分析.风沙土上所产果品最佳,潮土上的产品较差,但耐贮.梨园土体构型以松砂或紧砂为主,剖面性状分异不明显.土壤自然含水量5.29～7.82%,田间持水量29.4～31.7%.土壤有机质0.384～0.396%,全No.024～0.026%,碱解氮、速效磷、速效钾分别为24.55～29.55ppm,6.48～5.88ppm和33.88～36.52ppm,有效锌和有效硼含量低于临界值.梨树叶片含N2.08～2.77%,P_2O_50.329～0.347%,K_2O0.59～0.73%,钾素偏缺.增施有机肥,配合施用氮、磷钾肥和硼、锌微肥,是提高品质的必要措施.
The main producing area of Laiyang pear special survey of soil, and soil, plant and fruit analysis.Freeze sand soil produced the best fruit, the product on the soil is poor, but storability.Liyuan soil configuration with loose sand or Tight sand and no significant difference in profile traits.The soil natural water content was 5.29 ~ 7.82%, and the field water content was 29.4 ~ 31.7% .The soil organic matter content was 0.384 ~ 0.396%, all No.024 ~ 0.026%, N, P , Available potassium were 24.55-29.55ppm, 6.48-5.88ppm and 33.88-36.52ppm, respectively, and the available zinc and available boron content were below the critical value.The pear leaves contained N2.08 ~ 2.77%, P_2O_50.329 ~ 0.347%, K_2O0 .59 ~ 0.73%, potassium deficiency.Application of organic manure, with the application of nitrogen, phosphorus and potassium and boron, zinc fertilizer, is necessary to improve the quality of the measures.
