摘要
以苹果品种信浓红为试材,研究旱地果园不同肥水管理模式对土壤及苹果生长、产量及品质的影响。结果表明,与传统肥水管理模式比较,几种肥水利用模式均能提高叶片质量,促进新梢生长,提高光合速率,其中"肥水膜"一体化模式的土壤速效养分含量增加明显;与对照相比,新梢生长量增加31.37%,可溶性固形物质量分数增加20.18%,单果质量增加15.74%,单株产量增加24.64%。综合分析,"肥水膜"一体化是旱地果园简单易行的一种肥水高效利用模式。
Apple （Shinano red） were used to study the effect of different fertilizer and water manage ment modes on soil and apple growth, yield and quality in dryland orchards. The results showed that, compared to traditional fertilizer and water management mode, patterns of water and fertilizer in dif ferent treatments improved leaf quality obviously,hastened stem growth and enhanced net photosyn thetic rate. available nu mass by 15- 20.18% ,an fertilizer un dryland At the same time, irrigation with fertilizer under plastic film increased the contents of trients in soil. Compared to the CK,young shoot growth increased by 31.37% ,single fruit 74%, mass fraction of soluble sugar by 31. 33%, mass fraction of soluble solids by d d yield per apple tree by 24.64% The comprehensive analysis indicated that irrigation with er plastic film should be used as a simple and effective pattern of water and fertilizer in
