增效磷肥对冬小麦产量和磷素利用率的影响
Effects of value-added phosphate fertilizers on yield and phosphorus utilization of winter wheat
摘要
Abstract
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 .关键词
