【摘要】 为提高磷肥利用率、减少面源污染，对不同养分含量、添加不同促效添加剂的磷酸二铵开展了田间小区试验。试验共设10个处理，以不施肥为空白对照(CK),以常规施肥(复合肥15-15-15,CF)和普通磷酸二铵(18-46-0,FDAP)为施肥对照，考察了不同处理对冬小麦生物量、产量、株高以及土壤中速效养分含量等的影响。结果表明：磷活化型磷酸二铵处理的冬小麦生物量和籽粒产量增加效果较理想；磷活化型磷酸二铵处理的冬小麦株高在拔节期高于其他处理的，褐藻寡糖二铵(300)处理的冬小麦株高在灌浆期优于其他处理的；聚谷氨酸二铵处理的土壤中铵态氮和硝态氮含量最高，褐藻寡糖二铵(300)处理的土壤中有效磷含量最高，低聚多形态磷肥处理的土壤中速效钾含量最高。更多还原

【Abstract】 In order to improve the utilization rate of phosphate fertilizer and reduce diffused pollution, a field trial is conducted on diammonium phosphate with different nutrient contents and different efficiency promoting additives. The experiment includes 10 treatments, with no fertilization as the blank control(CK), conventional fertilization(compound fertilizer 15-15-15, CF) and ordinary diammonium phosphate(18-46-0, FDAP) as the fertilization control. The effects of different treatments on winter wheat biomass, yield, plant height, and soil available nutrient content are investigated. The results show that the phosphorus activated diammonium phosphate treatment has an ideal effect on increasing winter wheat biomass and grain yield. The winter wheat treated with phosphorus activated diammonium phosphate shows higher plant height during the jointing stage compared to other treatments, while the winter wheat treated with alginate oligosaccharides diammonium phosphate(300) shows better plant height during the grain filling stage compared to other treatments. The soil treated with polyglutamic acid diammonium phosphate has the highest ammonium and nitrate nitrogen content, while the soil treated with alginate oligosaccharides diammonium phosphate(300) has the highest available phosphorus content. The soil treated with low polymerized multi-form phosphate fertilizer has the highest available potassium content.更多还原
