| 摘 要： | 在实验室条件下分别模拟客土改良、排水改良、生物(苜蓿)改良等3种常用的盐碱地改良方法,以菜园土壤(正常土壤)和盐碱土(未改良的原始土)作为对照,研究了土壤微生物生态特征对不同改良方法的响应.结果显示:(1)土壤微生物区系及生理生化指标均对不同改良方式有良好的响应,其中土壤脲酶活性随土壤盐碱胁迫加剧而提高;(2)3种改良方式中,客土法在短期内最能改善土壤微生物各指标,其次是排水法、生物法;(3)排水法对土壤微生物生态状况不利;(4)生物法改善土壤微生物生态状况的速度相对较慢,但因其克服了客土法、排水法显见的缺点,因而有更好的应用前景.

| Abstract: | To cope with the situation amelioration and utilization of saline-alkali soil,three methods,namely,foreign soil,draining and planting were simulated in lab,meanwhile,two soil samples were taken at garden and saline-alkali field as controls respectively,for clarifying the response of microbial ecological characters to the three methods.The results showed that,(1) Well relativities between all the indexes of microbial ecological characters and different methods of amelioration in saline-alkali soil,particular... |
