摘  要:
为探究宁夏高沙窝地区瘠薄土壤风沙土的改良培肥技术,以结球甘蓝'京育一号'为参试品种,研究了施用不同NPK配比的复合微生物肥对土壤肥力及甘蓝生长的影响.结果表明:含NPK 20%-25%的复合微生物肥对甘蓝生长促进效果较好,也可使土壤有机质及速效养分含量显著增加,快速培肥土壤;含25%NPK复合微生物肥处理的甘蓝产量达94. 49 t/hm~2,比化肥处理的产量提高28. 3%;含20%NPK复合微生物肥处理的净收益最高,产投比最大.综上,高沙窝地区风沙土种植结球甘蓝复合微生物肥推荐配比为含20%NPK.

摘  要:
In order to explore the improvement and fertilization technology of aeolian sandy soil in Gaoshawo area of Ningxia,the effects of compound microbial fertilizer with different NPK ratios on soil fertility and cabbage growth were studied with the tested cabbage variety ‘Jingyu No. 1 '. The results showed that the compound microbial fertilizer containing 20% —25% NPK had better effects on cabbage growth,and could significantly increase the content of soil organic matter and available nutrients,and fertilize the soil rapidly. The yield of cabbage treated with 25% NPK compound microbial fertilizer reached 94. 49 t/hm~2,which was 28. 3% higher than that treated with chemical fertilizer. The treatment of compound microbial fertilizer containing 20% NPK had the highest net income and ratio of output to input. To sum up,the recommendation ratio of compound microbial fertilizer for planting cabbage in aeolian sandy of Gaoshawo area is 20% NPK.
