Abstract

The invention relates to a preparation method including the steps of preparing a humic acid extracting agent, preparing a humic acid extracting solution, preparing the humic acid synergistic carrier,and preparing the ammonium phosphate containing the humic acid synergistic carrier. The soil pH within 1 cm in ammonium phosphate fertilizer containing the humic acid synergistic carrier is reduced by0.3-1.4 units. Compared with commercially available ammonium phosphate, the soil Ca2-P and Ca8-P are increased by 22% and 16% on average respectively; the wheat root weight and vigor increase by 35%or more, the corn root fresh weight and vigor increase by 45.7% and 26.2% on average respectively; the wheat yield is improved by 12.6% on average, the phosphate fertilizer utilization rate is improved by 9.34%; the corn yield is improved by 16.1% on average, and the utilization rate of the phosphate fertilizer is improved by 10.7%.

Description

【Technical field】 [0001] The invention relates to the technical field of fertilizer production. More specifically, the present invention relates to a method for preparing ammonium phosphate containing humic acid synergistic carrier for winter wheat or spring corn base fertilizer. 【Background technique】 [0002] my country's phosphorus resource reserves only account for 5.5% of the world's total reserves, and the per capita resource amount is only 39% of the world's average level. Ammonium phosphate is the most important phosphate fertilizer in my country, but because it is easily fixed by calcium, magnesium, iron, aluminum and other metal ions after entering the soil, the utilization rate in the current season is only about 20%, causing huge economic losses and waste of resources. Only when the soil pH is 6-7, the concentration of available phosphorus is the highest. The content of calcium and magnesium ions in alkaline soil is high. After phosphorus enters the soil, more ...
