摘要
对 1 994 -1 996三年不同生态区重迎茬大豆采取缓解的各项农艺措施的产量结果分析表明 :处理间、区域间、年份间、处理×区域间、区域×年份间差异均达 1 %显著水平。各处理的综合评价是 :有机肥 >缓解剂 +钾肥 >破垄夹肥 >钾肥 >缓解剂 ;但各农艺措施受不同生态区、不同年份间及其各因素互作等影响较大 ,因此 ,应因地制宜采取农艺措施提高重迎茬大豆的产量。另外 ,采用各重迎茬减缓措施总体上东部低湿区好于西部干旱区 。
By applying different agronomic measures to continuous and alternate soybean cropping culture in different ecology localities in 1994-1996,the yield results showed that the level of significance of difference among treatments, locatities,years, treatments×locatities、 localities×year were all at 1%. The order of evaluation of each treatment was:organic fertilizer>release agent + potash fertilizer>applying fertilizer in cultivated ridges>potash fertilizer>release agent. But agronomic measures were influenced by different ecological areas and the interaction of factors.In addition,in low and humid east area,result using of each measure was better than that dry in west area and in years that had a suitable rainfall were better than the dry years.
