| 中文摘要: |
| 在陕西渭北旱塬果园,于苹果膨大期喷施不同浓度的锌肥,观测分析锌对果树生长和苹果品质的影响。结果表明,施锌可以抑制新梢生长速率,对果实直径生长速率、百叶干重、叶面积生长有显著的促进作用。其中,喷施0.5%浓度的锌肥,株产量比对照增加24.7%,可溶性固形物含量增加10.5%,还原糖增加27.5%,硬度提高了23.6%;喷施1%浓度的锌肥,株产量比对照增加40.2%,Vc含量提高了20.4%,可溶性糖增加了26.7%,花青苷含量提高了75%。综合考虑苹果生长与品质因素,该地区果园以喷施0.5%1%浓度的锌为宜。 |
| 英文摘要: |
| A garden experiment with different zinc concentration applied through foliar in fruit expanding stage was carried out in Weibei dry-land to study the effect of zinc fertilizer on apple trees growth and fruit quality.The results showed that zinc fertilizer could constrain the new shoots growth.Fruit diameter growth rate,dry matter accumulation and leaf area were increased significantly.After spray of 0.5% of zinc fertilizer to the foliar,the fruit weight increased by 24.7%,soluble solids increased by 10.5%,reductive sugar increased by 27.5% and hardness increased by 23.6% respectively in comparison with control treatment.Foliar application 1% of zinc fertilizer could increase fruit weight by 40.2%,Vc by 20.4%,soluble sugar by 26.7% and anthocyanin by 75% respectively in comparison with control treatment.The reasonable zinc fertilizer concentration for foliar application of apple trees was 0.5%～1% in Weibei dry-land. |
