摘要:

【目的】 研究主干型苹果树在水肥一体化模式下的最佳水肥耦合方案。【方法】 通过水肥一体化模式进行水肥耦合灌溉施肥管理,磷钾因素各设置2个水平(P1:109.5kg/hm2,P2:54.75 kg/hm2;K1:199.5 kg/hm2,K2:99.75 kg/hm2),水因素4个水平(充分灌溉W1:5 256m3/hm2、轻度亏缺W2:4 248 m3/hm2、中度亏缺W3:1 050 m3/hm2、重度亏缺W4:840 m3/hm2。采用随机区组设计,共16个处理。采用方差分析法和主成分分析法综合评价16个处理的苹果果实品质。【结果】 各处理间5个果实品质指标存在显著差异,综合得分最高处理为W2P1K1,其次为W1P1K1处理,最低处理为W2P2K2【结论】 7种果实品质指标简化为3种关键因子指标,建立果实品质的综合评价体系,确定16个水肥处理下果实品质综合排名前五分别为W2P1K1、W1P1K1、W4P1K1、W3P1K1和W1P2K1,W3P2K2处理排名最后。

Abstract:

【Objective】 To explore the optimal water and fertilizer coupling scheme of the main trunk apple trees under the integrated water fertilizer mode. 【Methods】 Field experiments with random block design of 16 treatments (two levels of phosphorus fertilizer, P1, 109.5 kg/hm2, P2, 54.75 kg/hm2 were perfprmed; two levels of potassium fertilizer, K1, 199.5 kg/hm2, K2, 99.75 kg/hm2); and four levels of water, W1, full irrigation, 5,256 m3/hm2, W2, mild deficit, 4,248 m3/hm2, W3, moderate deficit, 1,050 m3/hm2, W4, severe deficit, 840 m3/hm2) were conducted to investigate the response of apple fruit quality under different water and fertilizer coupling schemes. 【Results】 The results revealed that the fruit quality indexes were significantly different among the treatments.The highest comprehensive score treatment of fruit quality was W2P1K1, followed by W1P1K1, and the lowest treatment was W2P2K2. 【Conclusion】 Principal component analysis simplified the seven fruit quality indexes into three key factors, and a comprehensive evaluation system of fruit quality was established. The top five fruit quality rankings under the 16 water and fertilizer treatments were W2P1K1, W1P1K1, W4P1K1, W3P1K1 and W1P2K1, respectively.
