摘要：在元谋干热河谷对银合欢、山合欢、赤桉和大叶相思进行不同的整地方式种植,调查植株成活率、保存率、生长情况,对不同整地方式旱季、雨季土壤含水量、养分等进行测定分析。结果表明,水平沟和反坡平台套塘整地对苗木成活率、生长量提高幅度较大,浅沟套深塘整地对苗木成活率、生长量提高幅度最大,造林效果最好;水平沟、反坡平台套塘、浅沟套深塘整地旱季土壤含水量比鱼鳞坑整地提高22%～32%,雨季可提高26%～35%,在3种整地方式中,树种之间土壤含水量差异不大;不同的整地方式对土壤养分的增减不同,加大整地力度,促进植物生长,可以在一定程度上起到改良土壤的作用。
Leucaena leucocephala,Albizia kalkora,Eucalyptus camaldulensis and Acacia auriculi formis under different measure of soil preparation in Yuanmou dry-hot valley were planted.The reserving rate and survival rate and growth state of trees was investigated,and the nutrient,the moisture content of soil in dry and raining season of different measure of soil preparation was analyzed.The result showed： contour trench and hole in site preparation in terrace belt with outside higher than inside had an increase in amount of growth and survival rate.Hole in site preparation in shallow ploughing with a great increase in amount of growth and survival rate,the effect of afforestation is the best.The soil moisture content of the contour trench and hole in site preparation in terrace belt with outside higher than inside and hole in site preparation in shallow ploughing was increased by 22 %-32 % in dry season and 26 %-35 % in raining season compare with hole in site preparation like scale.The soil moisture content within trees in the three measure of soil preparation had little difference.Soil nutrient in different measure of soil preparation was increased or decreased.Increase of the extent of soil preparation could promote the growth of trees and improve the soil to a certain degree.
