穴贮砖对沙地梨树养分含量及土壤理化性质的影响

Effects of Hole Storage Bricks on Nutrient Content and Soil Pysical and Chemical Properties of Pear Trees in Sandy Land

  • 摘要: 以‘爱宕’梨树为试材,采用设置对照(CK)、穴贮砖A(T1)、穴贮砖B(T2)3个处理,研究了不同处理对南疆重盐碱沙地条件下种植的‘爱宕’梨树养分含量、土壤理化性质的影响,以期为改善南疆果园水肥提供参考依据。结果表明:施用穴贮砖能显著促进‘爱宕’生物量以及根茎叶中矿质营养元素含量;穴贮砖的施用显著提高了‘爱宕’梨树0~60 cm土层一个灌水周期的土壤含水量,提高了‘爱宕’梨品种0~80 cm土层中的全N、全P、全K、碱解氮、速效磷、速效钾含量及有机质含量,且在20~40 cm土层处T1、T2处理的提升效果最为显著,对其土壤的全N含量分别提高了20.42%、17.08%,全P含量分别提高了20.18%、12.65%,全K含量分别提高了18.58%、8.47%。综上所述,施加穴贮砖的T1、T2处理对南疆‘爱宕’梨树土壤理化性质及生长发育均有促进作用,促进效果表现为T1>T2>CK。

     

    Abstract: Taking ‘Adan’ pear tree as the test material, and three treatments were set, control(CK),hole storage brick A(T1) and hole storage brick B(T2),the effects of these treatments on the nutrient content and soil pysical and chemical properties of ‘Adan’ pear trees planted in heavy salt and alkali sandy land in southern Xinjiang were studied, in order to provide reference for improving the southern Xinjiang orchard water and fertilizer infiltration.The results showed that the application of fruit-hole storage bricks could significantly improve the biomass and mineral nutrient content in root, stem and leaves of ‘Adan’.The application of hole storage bricks significantly increased the soil water content in 0-60 cm soil layer of ‘Adan’ pear trees during one irrigation cycle, and increased the contents of total N,total P,total K,alkali-hydrolyzed nitrogen, available phosphorus, available potassium and organic matter in 0-80 cm soil layer of ‘Adan’ pear varieties, and the improvement effect of T1 and T2 treatment was most significant in 20-40 cm soil layer.Total N content, total P content and total K content were increased by 20.42% and 17.08%,20.18% and 12.65%,18.58% and 8.47%,respectively.In summary, the application of T1 and T2 treatment of fruit tree storage bricks could promote the soil physical and chemical properties and growth of ‘Adan’ pear trees in southern Xinjiang, and the promoting effect was T1>T2>CK.
