含聚磷酸铵肥料对作物产量效应影响的整合分析

Integrated Analysis of the Effect of Fertilizer Containing Ammonium Polyphosphate on Crop Yield

以聚磷酸铵、不同磷肥为主要关键词,在中国知网(CNKI)和Web of Science数据库共筛选出75篇文献(中文55篇,英文20篇),获得527组数据。以施用磷酸铵肥料为对照组,施用含聚磷酸铵肥料为试验组,采用整合分析的方法,定量评价施用含聚磷酸铵肥料对作物产量、土壤有效磷含量和磷肥利用率的影响。与施用磷酸铵肥料相比,施用含聚磷酸铵肥料可显著提高作物产量,增长幅度(E)为4.4%;虽可提高土壤有效磷含量(E为3.0%),但效果不显著;可显著提高磷肥利用率(E为56.0%)。作物产量效应的亚组分类分析结果表明:含聚磷酸铵肥料在番茄和玉米上的施用效果较好;作物产量、土壤有效磷含量、磷肥利用率随土壤有机质含量、土壤pH的升高而提高,随聚磷酸铵含量升高而降低,随聚磷酸铵平均聚合度的增大而提高。施用含聚磷酸铵肥料提高了作物产量、土壤有效磷含量和磷肥利用率,增产效应受土壤性状、作物类型、聚磷酸铵含量和聚磷酸铵平均聚合度的影响。

Using ammonium polyphosphate and different phosphate fertilizers as the main keywords,a total of 75 articles(55 in Chinese and 20 in English)are selected from the China National Knowledge Infrastructure(CNKI)and Web of Science databases,and 527 sets of data are obtained.Using ammonium phosphate fertilizer as the control group and fertilizer containing ammonium polyphosphate as the experimental group,the integrated analysis method is used to quantitatively evaluate the effects of applying fertilizer containing ammonium polyphosphate on crop yield,soil available phosphorus content,and phosphorus fertilizer utilization efficiency.Compared with the application of ammonium phosphate fertilizer,the application of fertilizer containing ammonium polyphosphate can significantly increase crop yield,with an increase rate(E)of 4.4%.Although the effective phosphorus content in soil(E is 3.0%)is increased,the effect is not significant.The utilization efficiency of phosphorus fertilizer(E is 56.0%)can be significantly improved.The sub-group classification analysis of crop yield effects shows that the application of fertilizer containing ammonium polyphosphate on tomatoes and maize is more effective.Crop yield,soil available phosphorus content,and phosphorus fertilizer utilization efficiency increase with the increase of soil organic matter content and soil pH,decrease with the increase of ammonium polyphosphate content,and increase with the increase of average polymerization degree of ammonium polyphosphate.The application of fertilizer containing ammonium polyphosphate increases crop yield,soil available phosphorus content,and phosphorus fertilizer utilization efficiency.The yield increase effect is influenced by soil characteristics,crop type,ammonium polyphosphate content,and average polymerization degree of ammonium polyphosphate.
