| 摘 要： | 为了探讨灰枣生长期内不同施肥处理措施对枣园土壤速效养分含量的影响情况,于2014年3月采用不施肥、常规施肥和施用不同种类生物肥共3大类9种处理进行田间试验,并于同年7~10月在灰枣不同生长期测定了各处理区域土壤中的碱解氮、速效磷、速效钾、有机质这4种养分的含量,研究了不同施肥处理下灰枣不同成熟期土壤各养分的动态变化情况。结果表明,不同处理、不同成熟期土壤各养分含量间均有差异,施用生物肥可以显著提高土壤中各养分的含量。

Effects of different fertilization treatments on contents of soil nutrients in gray jujube orchard |

| Abstract: | In order to explore effects of different fertilization treatments on orchard soil in the growing season of gray jujube, three groups experiments with 9 treatments were conducted in March 2014, including non-applied fertilizer, conventional fertilizer and biological-organic fertilizers. The contents of alkali solution N, available P, available K and organic matter in soil during different growth periods of gray jujube from July to October were quantiifed and the dynamic changes of the contents of soil nutrients during different mature stages of gray jujube in different treatments studied. The results showed that the contents of soil nutrients were different in different treatments at different mature stages, and applying biological-organic fertilizer could signiifcantly improve the contents of soil nutrients. |
