| 摘 要： | 通过试验证明果园生草制是我国干旱、半干旱地区果园土壤管理的一个行之有效的模式。果园生草覆盖区与对照相比土壤养分明显提高,有机质增加4.1g/kg～4.7g/kg,提高47%～54%;全氮增加0.05g/kg～0.08g/kg,提高7.0%～12%;有效磷增加3.5mg/kg～6.2mg/kg,提高20%～35%;速效钾增加27mg/kg～75mg/kg,提高9.0%～25%;苹果可溶性固形物、硬度、果形指数、可溶性糖及糖酸比等指标明显提高,可滴定酸明显下降;苹果产量和经济效益显著提高,提高幅度分别为12.73%～31.57%和15.17%～36.22%。 |

Effect of Grass Cover on Soil Nutrient and Yleld and Quality of Apple |
|
| Abstract: | Grass cover system is an effective measure for orchard management of the arid and semiarid area in our country.Soil nutrient was improved obviously . Organic matter,total nitrogen , available phosphorus , and potassium were increased by 47-54% , 7.0-12% ,20-35% ,an ot 7.0-25% respectively . Soluble solid substance , hardness and sugar to unonic-acid ratio were improved obviously .Titratable acid was decreased obviously . Ylelds of apple were increased by 12.73-31.75%,and economic effect by 15.17-36.2%. |
