[目的]为新型肥料的研制提供参考依据。[方法]配制新型白菜专用肥(N∶P2O5∶K2O=16∶7∶13),设5个肥料处理,比较了新型专用肥、普通肥料和俄罗斯复合肥对大白菜的施用效果。[结果]新型专用肥显著或极显著增加大白菜的产量。与普通肥料相比,施用等养分量、等养分比例的肥料,新型专用肥可增产10.0%;与俄罗斯复合肥(N∶P2O5∶K2O=16∶16∶16)相比,施用等养分量的新型专用肥可增产20.0%。新型专用肥能明显改善大白菜品质,可溶性糖含量可提高2.7~3.4 g/100 g,达到显著或极显著水平;还可明显提高肥料利用率,氮、磷、钾比普通肥料分别提高3.4%、2.4%和9.8%,比俄罗斯复合肥分别提高-0.1%、10.0%和9.5%。[结论]研究开发新型专用肥是实现作物增产增收和保护环境的一项有效措施。
[Objective] The research aimed to provide reference for the development of new fertilizer. [Method] New cabbage special fertilizer (N: P2O5:K2O = 16:7:13) was prepared and five manure treatments were set up to compare the application effects of new special fertilizer, common fertilizer and Russian compound fertilizer on Chinese cabbage. [Result] New special fertilizer significantly increased the yield of Chinese cabbage significantly or very significantly. Compared with common fertilizer, the amount of nutrients such as nutrients, the proportion of nutrients such as fertilizers, new special fertilizer can increase 10.0%; and Russian compound fertilizer (N: P2O5: K2O = 16:16:16) compared to the amount of nutrients New special fertilizer can increase 20.0%. New special fertilizer can significantly improve the quality of Chinese cabbage, soluble sugar content can be increased 2.7 ~ 3.4 g / 100 g, reaching significant or very significant level; but also significantly improve fertilizer utilization, nitrogen, phosphorus and potassium than ordinary fertilizer increased by 3.4% , 2.4% and 9.8%, respectively, than the Russian compound fertilizer increased by -0.1%, 10.0% and 9.5%. [Conclusion] The research and development of new special fertilizer is an effective measure to increase crop yield and protect the environment.
