| 摘 要： | 目的]为了研究商品有机肥对土壤肥力的改善作用。方法]在青海省河湟温暖灌区,利用田间小区试验研究了不同用量商品有机肥处理与氮磷肥配施对春油菜产量、非经济部分产量及土壤养分的影响。结果]与氮磷肥处理相比,增施商品有机肥油菜籽产量可提高5.4%~19.4%,增产184~665 kg/hm2;角壳产量增幅为7.2%~19.2%,增产168~449 kg/hm2;茎秆产量增幅为4.3%~22.1%,增产176~914 kg/hm2。施用商品有机肥后土壤有机质年增量为0.8~1.3 g/kg,部分土壤速效和全量养分有明显的增加趋势。结论]施用商品有机肥对土壤肥力有一定的促进作用。

| Abstract: | Objective ] The research aimed to study the improvement of different rate of commodity organic fertilizer on soil nutrients. Meth- od ] The field plot experiment was carried out in Minhe City, Qinghai Province to study the effects of differet amount of commodity organic fertiliz- er on seed,straw, shell yield of spring rapeseed and soil nutrients. Result] Compared with the application of nitrogen and phosphors fertilizer, the yield of an added application of commodity organic fertilizer was increased from 184 kg/hm2 to 665 kg/hm2, and the rate ranged from 5.4% to 19.4%. The yield of spring rapeseed shell changed from 168 kg/hm2 to 449 kg/hm2, and the rate ranged from 7.2% to 19.2%. The yield of spring rapeseed straw changed from 176 kg/hm2 to 914 kg/hm2, and the rate ranged from 4.3% to 22.1%. After applying commodity organic fertilizer, the content of organic matter in the soil increased in a year from 0.8 g/kg to 1.3 g/kg, some total and rapidly available nutrients were improved. Conclusion~ The commodity organic fertilizer could improve the soil fertility. |
