- 摘要:
- 以昆明团结办事处苹果园和宜良县雪峰生态园的梨园为研究对象,对生草和清耕2种果园土壤管理方式的土壤肥力状况进行了调查、测定和分析。结果表明:苹果园和梨园生草1年半后,土壤有机质含量有所提高,且土壤水解氮、有效磷、速效钾含量均有不同程度的提高,但全钙、全镁、全锌和全硼的含量在整体上呈下降的趋势;土壤养分含量一般表现为表层土(0~20 cm)大于深层土(20~40 cm)。果园生草改善了果园理化性质,土壤肥力得到提高。
- Abstract:
- Taking apple orchard in Kunming region and pear orchard in Xuefeng Ecology Garden of Yiliang County as experimental object,a survey analysis and determination was conducted on the mulching and clean tillage soil fertility in two kinds of orchard soil management.The results showed that the pear and apple orchard mulching a year and a half later,increased soil organic matter(OM) content,the soil hydrolysis nitrogen(N),available phosphorus(P) and available potassium(K) content in varying degrees increase,but total calcium(Ca),total magnesium(Mg),total zinc(Zn) and total boron(B) content had full downward trend in overall;soil nutrient content was generally expressed as topsoil (0-20 cm) was greater than the deep soil (20-40 cm).Orchard mulching improved physical and chemical properties,and the soil fertility was improved.
