摘要
为了研究不同肥料配比对旱地"红富士"苹果品质的影响,以"长富二号"苹果为试材,研究了生草覆盖和清耕制下不同施肥处理对苹果品质的影响。结果表明:生草能促进苹果果实果形指数的提高,养分供应不足或施肥不平衡均会降低果实果形指数;有机肥与氮磷钾肥配合(MNPK)生草较清耕提高2.26%;生草可以降低果实中可滴定酸、可溶性糖含量,但程度不同,以清耕制为对照,生草覆盖下单施氮磷肥(NP)处理糖酸比显著降低17.44%,MNPK显著提高17.42%;不同肥料配比使果实中维生素C含量提高12.56%～59.28%,其中有机肥与氮磷钾肥配合(MNPK)处理效果最佳。综合分析,无论在生草覆盖,还是清耕制下有机无机肥配施均可提高红富士苹果的品质,尤以生草覆盖下的效果更为明显。
In order to elucidate the effect of fertilizer ratio on ＇Red Fuji＇ apple quality in dry land,taking ＇Changfu 2＇ apple as material, the effect of 5 fertilizer treatments on the quality of it under grass covering and conventional tillage management was studied. The results showed that the grass covering could promote fruit index,and nutrient insufficient or no balance could decrease fruit shape index. Compared with conventional tillage management, MNPK under grass covering was enhanced 2.26~. Soluble sugar and titration acid contents decreased to different extent under grass covering. Compared with conventional tillage management, the sugar-acid ratio significant decreased 17.44% in NP treatment,and increased 17.42% in MNPK treatment under grass covering. Compared with no fertilizer, VC content increased 12. 56%-59. 280% under other fertilizer treatments,with MNPK had the best effect. It suggested that in the orchard with grass covering or conventional tillage management, mixed fertilizer of inorganic fertilizers and organic fertilizer was a rational nlanagement in promoting apple quality,especially the grass covering orchard.
