摘　　要：以中棉所79为材料,通过设置高垄覆膜、高垄不覆膜、喷洒土壤改良剂、喷洒土壤改良剂+高垄覆膜、喷洒土壤改良剂+高垄不覆膜和平作覆膜6种种植方式,研究不同种植方式对盐碱地棉花产量、干物质质量与氮磷钾积累的影响。结果表明,与平作覆膜种植方式相比,喷洒土壤改良剂和喷洒土壤改良剂+高垄覆膜处理子棉产量显著提高,增幅分别达45.88%和42.24%。进一步分析表明,这两种种植方式最有利于提高棉花干物质质量和氮、磷、钾的积累量。Using CCRI 79 as the study material, six different planting patterns were designed to investigate the effects of planting pattern both on cotton yield and on the accumulations of dry matter, nitrogen, phosphorous, and potassium. The tests were per- formed using saline fields that were high-ridged and mulched; high-ridged and non-mulched; sprayed with Kxi^ium in saline-al- kali soil; sprayed with Krilium, high-ridged and mulched; sprayed with Ka＇ilium, high-ridged and non-mulched; and traditional, mulched shallow seeding as the control. The results showed that the yields for the treatments with Krilium spray, both for the saline-alkali soil and the high-ridged mulching, were significantly higher than the control by 45.88% and 42.24%, respectively. Further analysis revealed that these two treatments increased the accumulations of dry matter, nitrogen, phosphorous, and potas- sium in cotton.
