摘 要：为探讨油菜绿肥翻压对盐碱土的改良效果，在中度盐碱荒地上设置油菜绿肥翻压还田1年(T1)、
翻压还田2年(T2)和无 绿肥还田(CK)三个处理，研究油菜绿肥对盐碱土壤理化性状、盐组分及棉花产量的影响。结果表明：油菜绿肥翻压的效果表现为 T2〉T1>CK，与CK 相比,T2和T1处理分别使棉花籽棉产量增加27.5%和13.5%(P<0.05) ;T2处理土壤pH 值和电导率比CK 分别降 低1.0个单位和0.7 mS ・cmT,T2处理全氮、全磷、全钾和有机质比CK 分别增加44.8%、9.1%、6.5%和115.2%；油菜绿肥粉碎还田显 著降低盐碱离子含量，其中，与CK 相比，T2处理土壤盐基阳离子Ca 2\K\Mg 2+和Na *
*含量显著(PvO.05)降低30.3%.42.7%.41.0% 和30.5%，土壤盐基阴离子Cl\SOi\COr 和HCO 洽量显著(P<0.05)降低39.2%.33.0%.32.2%和32.1%。研究表明，油菜绿肥能改 善土壤理化性状、增加养分含量、降低盐碱离子含量，对新疆绿洲干旱区盐碱土壤具有较好的改良效果。

(Shihezi University/Key Laboratory of Oasis Ecology Agriculture of the Xinjiang Production and Construction Corps, Shihezi 832003, China) Abstract : We investigated the effects of returning rape green manure to field on saline alkali soil improvement in Xinjiang. Moderately saline and alkaline wastelands were subjected to three rape green manure treatments : 1 year(Tl ), 2 years(T2), and no green manure(CK) to elucidate the effects of returning rape green manure on the physical and chemical properties of saline soil, soil salt composition, and cotton yield. The results showed that the effect of returning rape green manure was as follows : T2>T1>CK. Compared with CK, T2 and T1 treatments significantly (P<0.05) incread cotton ed yield by 27.5% and 13.5%, respectively. The pH value and conductivity of T2 were 1.0 unit and 0.7 mS • cm -1 lower, respectively, than that of CK; Moreo
ver, total nitrogen, total phosphorus, total potassium, and organic matter content of T2 incread by 44.8%, 9.1%, 6.5%, and 115.2%, respectively. The content of saline-alkali ions in the soil was reduced by returning rape green manure to the field. Compared with CK, the content of T2 salt composition Ca 2+, K +, Mg 2+, Na +, Cl -, SOV, COV, and HCO 3 significantly (P<0.05) decread by 30.3%, 42.7%, 41.0%, 30.5%, 39.2%, 33.0%, 32.2%, and 32.1%, respectively. The results indicated that rape green manure could improve the physical and chemical properties of soil, increa nutrient content, decrea saline- alkali ion content, and have a good effect on saline-alkali soil improvement in the oasis arid area of Xinjiang.
