许昌市新城区绿化带土壤理化特性及管理措施

以河南许昌市新城区绿化带土壤理化特性为研究对象,对土壤有机质、全氮、速效磷、速效钾含量和酸碱性等理化指标进行了分析,结果表明:绿化带土壤处于微碱性状态,普遍缺乏氮、钾和有机质,而磷含量相对较高.因此,在绿化带管理卜要综合考虑土壤养分状况和作物的养分需求,适当提高氮、钾和有机质的用量,达到养分平衡.

Physical and chemical properties and management measures of soil of the green belt in new urban areas of Xuchang city

The subject of this study was the physical and chemical properties of the soil of the green belts in Xuchang city,Henan province.The contents of organic matter,total N,available P,available K and other indexes such as pH have been analyzed to find out the soil constraint factors which influence the growth of the vegetation so as to provide the technological guidance of rational fertilization on the city green belts.The results showed that the green belt soil was in slight alkalinity and deficient of N,K and...
