聚磷酸盐替代部分正磷酸盐增产作用研究普正仙1，宗世荣1，陈泽新2，王芳1，汤利2，柳展3，危常州4（1.云南云天化股份有限公司研发中心，云南昆明650228；2.云南农业大学资源与环境学院，云南昆明650500；3.勐海曼香云天农业发展有限公司，云南西双版纳666205；4.石河子大学农学院，新疆石河子832003）［摘要］在等磷量的前提下，研究采用聚磷酸铵或三聚磷酸钾替代部分正磷酸盐，并全部作追肥或全部作基肥条件下对水稻的增产效应，以期为复合肥中添加聚磷酸盐提高磷肥效率奠定基础。实验结果表明，聚磷酸铵或聚磷酸钾替代4%或8%正磷酸盐处理，比只用正磷酸盐施肥处理水稻增产1.15%~18.39%，其中聚磷酸铵的增产作用优于三聚磷酸钾。聚磷酸盐替代部分正磷酸盐对水稻品质的影响表现为提高了水稻粗脂肪含量，降低粗蛋白含量；作追肥时降低了水稻粗灰分含量。［关键词］聚磷酸盐；正磷酸盐；水稻产量；营养品质；外观品质［中图分类号］S147.2［文献标志码］B［文章编号］1007-6220（2023）01-0048-04EffectofpolyphosphatereplacingpartialorthophosphateonincreasingproductionPUZhengxian1,ZONGShirong1，CHENZexin2,WANGFang1,TANGLi2,LIUZhan3,WEIChangzhou4（1.Research&DevelopmentCenter，YunnanYuntianhuaCo.,Ltd.，Kunming650228，China；2.CollegeofResourcesandEnvironment,YunnanAgricultureUniversity，Kunming650500，China；3.MenghaiManxiangyuntianAgricultureDevelopmentCo.,Ltd.，Xishuangbanna666205，China；4.AgronomyCollege,ShiheziUniversity，Shihezi832003，China）Abstract：Underthepremiseofequalphosphoruscontent,theyieldincreaseeffectof4%or8%orthophosphatereplacedbyammoniumpolyphosphateorpotassiumtripolyphosphateisstudiedundertheconditionthatallofthemareusedastopdressingorbasefertilizer,inordertolayanfoundationforaddingpolyphosphatetocompoundfertilizertoimprovetheefficiencyofphosphatefertilizer.Theresultsshowthatwhen4%or8%orthophosphateisreplacedbyammoniumpolyphosphateorpotassiumpolyphosphate,thericeyieldisincreasedby1.15%to18.39%comparedwiththatwhenonlyorthophosphateisused.Theyieldincreaseeffectofammoniumpolyphosphateisbetterthanthatofpotassiumtripolyphosphate.Theeffectofpolyphosphatereplacingpartialorthophosphateonricequalityistoincreasethecontentofcrude...
