| 摘 要： | 在不同立地（盐碱地、草场退化地、废弃地）栽植沙棘，通过3年的试验研究（1998～2000年），结果表明：沙棘在pH值8．77～9．18之间的盐碱地栽植可以成活，同时沙棘林下土壤各单项肥力指标多数都有不同程度的提高，沙棘栽植2年后土壤pH降低0．1～0．23左右，全盐量绝对值降低0．01％～0．02％，有机质绝对值增加0．01％～0．15％左右。草场围栏成效快，围护效果显著。废弃地栽植沙棘生长正常，株高达76．4cm、冠幅达79．2cm×76．2cm。

| Abstract: | According to three years （1998--2000） study on seabuckthorn be planted in different soil conditions （saline-alkali soil, grassland degradation and waste land）, the results shows that seabuckthorn can survive in saline-alkali soil which pH value is between 8.77 and 9.18. It has some impact on the growth of seabuckthorn after the value is higher than 8. 77. At the same time, seabuckthorn can improve the saline-alkali soil condition. After two years planting of seabuckthorn, soil pH value can he reduced about 0.01, full-salt value can decrease 0.01 percent and organic matter will increase about 0. 01-0.15. Using pasture fencing has quick effect and great results. Seabuckthorn be planted in waste land grows normally, which height is up to 76.4cm and crown can reach 76.2cm to 79.2cm. |
