| 摘 要： | 本文是针对土默川平原不同碱化土壤和化学改良后土壤的团粒结构进行对比研究,研究结果表明:中度碱化土壤团粒结构占29.3%,相应改良后的团粒结构上升到45.6%;重度碱化土壤团粒结构占22.1%,明显减少;碱土的团粒结构则更少,仅为16.5%,但经化学措施改良后也可达到32.55%。这说明土壤碱化程度越大,团粒结构越少;改良后土壤的团粒结构明显增加。

| Abstract: | this research was carried out on the aggregateof different solonized soiland the chemical improved soil in Tumuochuan Plain. the results showed that the amount of soil aggregatewis 29.3% in middle solonized soil,correspondingly the improved soil aggregatewas 45.6%.Soil aggregateof serious solonizedsoil was 22.1%.The amount of soil aggregateon solonetz was 16.5% only,but after improving,it can reach 32.55%.It is showed that the sodication wasthe serious,the less aggregateof soil was,but that inimproved soil increased obviously. |
