摘要: 在乌兰布和沙漠的东北缘选取了8种防护林配置模式的土壤作为试验样地,通过对所采集土样的室内分析,得出各配置模式的pH值、有机质含量、全量养分(N,P,K)含量以及速效养分(N,P,K)含量等土壤化学指标数值,根据这些数据分析了8种防护林对农田土壤肥力的影响。结果表明:8行的3箭杆杨+2新疆杨+3箭杆杨、8行的小美旱杨及4行的1榆树+2旱柳+1榆树的配置模式对土壤肥力有较为明显的改良,其中,作用最为突出的是8行的3箭杆杨+2新疆杨+3箭杆杨配置模式,碱解氮和速效钾比旷野提高了417%和138%;改良作用最弱的两种配置模式为8行的4旱柳+4小美旱杨和2行加杨,其水平与旷野地相当。

Abstract: With 8 kinds of soil that are affected by different farmland sheltbelts in the northeast part of Ulanbuh Desert being selected as research objects and the analysis on soil samples, this paper gains data about soil pH, organic content, total nutrient (N , P and K) and available nutrient (N , P and K). At the same time, the paper analyses the effects of 8 kinds of farmland sheltbelts on farmland soil fertility according to these data. The result indicates that the farmland sheltbelt having 8 lines arrangement (3 lines P. nigra L. var. thevestina plus 2 lines P. alba var. pyramidalis plus 3 lines P. nigra L. var. thevestina and 8 lines P. popularis) and 4 line arrangement (1 line Ulmus pumila L.puls 2 lines Salix matsudana Koidz puls 1 line Ulmus pumila L.) improves noticeably soil fertility. Among the three arrangements, the farmland sheltbelt having 8 lines (3 lines P. nigra L. var. thevestina plus 2 lines P. alba var. pyramidalis plus 3 lines P. nigra L. var. thevestina) has the greatest impact on soil fertility, its available nitrogen and potassium have increased 417%, 138% than the wilderness. The farmland sheltbelt with 8 line arrangement (4 lines Salix matsudana Koidz plus 4 lines P. popularis) and 2 lines P. Canadensis Moench. Verz hardly improves soil fertility.

Key words: farmland sheltbelt, different arrangements, soil fertility
