摘要
以连云港花果山酒店苗木绿化工程土壤改良为例,采用灌水、施石膏、有机肥和生理酸性化肥(硫酸铵、过磷酸钙和硫酸钾)的改良方法,监测土壤盐分、pH值、氮磷钾含量的变化,关注苗木生长状况。结果表明:灌水后,土壤盐分含量从0.32%降至0.11%(P<0.05)。施石膏、有机肥和化肥后,土壤pH值从9.13降至8.72(P<0.05);土壤有机质、全氮、碱解氮、速效磷和速效钾含量显著提高(P<0.05)。翌年7月,改良地新栽植苗木成活率达100%。
An successful instance was offered to reveal the effects of irrigation,gypsuming and fertilization on soil saltinity,p H value and fertility in Huaguoshan Hotel Greening Project,Lianyungang City. After irrigation,soil salt content decreased from 0. 32% to 0. 11% significantly（ P〈0. 05）. And after gypsuming and fertilization,soil p H value decreased from 9. 13 to 8. 72 significantly（ P〈0. 05）. In addition,soil organic matter,total nitrogen,alkaline hydrolysis nitrogen,available phosphorus and available potassium contents were significantly increased（ P〈0. 05）. In the next July,the survival rate of new planting seedlings reached 100%.
