摘要
为探明海藻酸磷酸二铵在夏玉米上的应用效果,采用田间试验,研究了磷酸二铵和海藻酸磷酸二铵推荐施磷量及减磷20%对夏玉米产量、养分积累及磷肥利用效率的影响。结果表明,夏玉米施磷显著增产10.3%~28.5%;海藻酸磷酸二铵较磷酸二铵处理增产7.5%,磷肥表观利用率、农学效率和偏生产力分别提高11.2个百分点、13.1 kg/kg和13.1 kg/kg,氮磷钾积累量分别增加10.2%、15.5%和14.7%;海藻酸磷酸二铵减磷20%与磷酸二铵推荐施磷量处理的玉米产量、氮磷钾积累量均无显著差异,磷肥表观利用率提高2.7个百分点,偏生产力显著提高32.8 kg/kg。豫北潮土中产区海藻酸磷酸二铵具有增产效果,磷肥利用效率有所提高,施用海藻酸磷酸二铵减磷20%可保证夏玉米产量。
In order to explore the application effect of alginate diammonium phosphate on summer maize,the field experiment was carried out to study the effect of the application of recommended total phosphate and phosphate reduction 20%on the yield,nutrient accumulation and utilization efficiency of phosphorus fertilizer in summer maize.The results showed that phosphorus application in summer maize increased significantly by 10.3%~28.5%.Alginate diammonium phosphate increased production by 7.5%over diammonium phosphate.Apparent utilization of phosphate fertilizer,agronomic efficiency,and partial productivity increased by 11.2%,13.1 kg/kg and 13.1 kg/kg,respectively.The accumulation of NPK increased by 10.2%,15.5%and 14.7%,respectively.There was no significant difference between the yield and the accumulation of nitrogen,phosphorus,and potassium of alginate diammonium phosphate reduced by 20%and the recommended amount of phosphorus application.Apparent utilization of phosphate fertilizer increased by 2.7%,and partial productivity increased by 32.8 kg/kg.The production of alginate diammonium phosphate in northern Henan fluvo-aquic soil production area has the effect of increasing yield.The utilization efficiency of phosphate fertilizer has been improved,and the application of alginate diammonium phosphate with the phosphorus reduction by 20%can ensure the yield of summer maize.
