摘 要：
果园生草是园区土壤可持续性耕作的重要手段。试验在辽宁农业职业技术学院酿酒葡萄园进行,果园覆盖鼠茅草,研究果园生草对于果园土壤营养成分、土壤含水量,土壤容重等衡量土壤理化性质重要指标影响。结果表明,随年份逐渐增加,果园生草可有效提高土壤表层有机质及氮磷钾含量,最高可达11.75 mg/kg、126 mg/kg、87 mg/kg、156 mg/kg。而清耕随年份增加,会降低所有土层土壤有机质含量,二年内清耕土壤表层土壤氮磷含量变化不明显,钾元素含量降低明显。生草与清耕相比,生草后土壤保水保墒能力较好;生草可有效增加土壤孔隙度与通透性。

摘 要：
Weed growing in the orchard is an important mean of sustainable farming.The experiment is carried out at vineyards in Liaoning Agricultural Technical College.Orchards are covered by Vulpia myuros C.Gmelin in order to study the influence of weed growing in orchard on soil physical and chemical properties,such as soil nutrients,soil moisture and volume weight of soil important indicators.The results show that weed growing can effectively improve the content of soil organic matter and the NPK content can hit to 11.75 mg/kg,126 mg/kg,87 mg/kg and 156 mg/kg.While,the clean cultivation will reduce oil organic matter content,content of oil nitrogen and phosphorus changed unobviously,but,the potassium content reduced obviously.So contrasting with clean cultivation,the soil moisture ability is good after weed growing.It can effectively increase soil porosity and permeability.
