【摘要】 六年试验结果表明：小麦产量轮作高于连作。在所有处理组合中，耕翻施有机肥效果最佳；在等量化肥情况下，土壤耕作最好的是耕翻，其次为深松，免耕效果最差；培肥措施中，有机肥处理组合平均产量最高，其次是化肥处理，秸杆还田居第三位；以上处理组合均极显著地高于对照处理。更多还原

【Abstract】 The research showed that rotation yield of spring wheat is higher than continuous cultivation in the past six years. Effectiveness of ploughing and organic fertilizer-dressing are the best in all practices. On the same fertilizer-dressing, ploughing is the best in soil cultivation, subsoiling is the second, no-ploughing is very poor. In fertilizer-dressing practices, highest average yield of wheat is organic fertilizer-dressing, the second is fertilizer-dressing, the third is crop back straw. Wheat yield of all above practices are remarkable high than control treat.更多还原
