在实验室条件下分别制备了含腐植酸、海藻酸和谷氨酸3种增效剂的增效磷肥，运用土柱栽培试验研究等磷（设置低、高2个施磷水平）投入条件下不同增效剂添加量的增效磷肥对小麦产量和磷肥利用率的影响。结果表明，1）低磷水平下，增效磷肥处理小麦子粒产量比普通磷酸一铵提高9.74％33.54％，高磷水平下，含腐植酸增效磷肥和含海藻酸增效磷肥处理小麦子粒产量分别比普通磷酸一铵增加26.81％和30.65％。低磷和高磷水平下，不同增效磷肥处理小麦子粒产量均随增效剂添加量的增加而提高。2）低磷和高磷水平下，增效磷肥处理小麦子粒含磷量与普通磷酸一铵处理差异不显著。3）低磷水平下，增效磷肥处理小麦吸磷总量比普通磷酸一铵增加14.81％42.59％，磷肥的表观利用率平均提高了8.7126.21个百分点；高磷水平下，腐植酸增效磷肥和海藻酸增效磷肥处理小麦吸磷总量分别比普通磷酸一铵增加18.18％和32.73％，磷肥的表观利用率平均提高了6.13和10.19个百分点。

Three kinds of value-added phosphate fertilizers used in the study were made by mixing a certain ratio of modified humic acid , alginic acid and glantamic acid with mono-ammonium phosphate ( MAP ) , then dried and grounded for experiments .Pot experiments with two input rates of P 2 O5 , 0.05 and 0.10 g/kg soil were conducted to investigate the effects of the three value-added phosphate fertilizers on yield , phosphorus uptake and P fertilizer use efficiency of winter wheat .The results show that compared to the MAP treatment , the grain yields increased by 9.47%to 33.54%at low P2 O5 input and 26.81% and 30.65% at high P2 O5 input with humic acid phosphate fertilizer and the alginic acid phosphate fertilizer respectively .The grain yields also increased with the increasing quantity of synergist ratio in the two value-added phosphate fertilizers in both P application rates .There were no significant differences in grain P contents between the wheat using MAP and the value-added phosphate fertilizers at both the two P2 O5 input rates, but the increase in total P uptakes of wheat are different in the two P 2 O5 input rates. The P uptake with value-added MAP treatments are 14.81%to 42.59%higher of those in MAP treatment at P 2 O5 input rate of 0.05 g/kg soil, and 18.18% and 32.73% higher at 0.10 g/kg soil level.The corresponding inorganic-P apparent recovery efficiencies increase are 23.06%to 26.21%and 6.13%and 10.19%, respectively under the two P application rates .
