脱硫石膏改良龟裂碱土对枸杞根际土壤理化性质及根系生长的影响

龟裂碱土主要分布在宁夏银川平原,是贺兰山碱化山体土壤在山洪冲击下淤积于银川平原而成。由于这种土壤干时地表皲裂似龟背状,故称＂龟裂碱土＂,也因土壤质地坚硬,表面呈白色,又称＂白僵土＂[1]。

In this study,the rhizosphere soil properties of Takyr Solonetzs ameliorated with FGDG,and its effect on root growth of Lycium barbarum were studied.The results indicated that with increasing applications of FGDG,the contents of Na＋,K＋,Mg2＋,Cl-,and HCO3-in rhizosphere soil decreased gradually with the ratio of 51.9%,16.7%,42.7%,44.7% and 28.2%,respectively,while the contents of Ca2＋ and SO42-showed an increasing trend and increased by 96.9% and 80.4% compared with those of the CK.As the content of exchangeable Na＋ decreased with the increasing application of FGDG,the exchangeable sodium percentage（ESP） and soil pH values decreased from 32.2% and 10.5 to 18.1% and 7.82,respectively and thus the soil phy
