Production of urea phosphate type acid water-soluble fertilizer and its application effect on soybean planting in calcareous soil
The preparation of urea phosphate type acid water-soluble fertilizer is introduced.In order to verify the feasibility of applying urea phosphate type acid water-soluble fertilizer on the whole fertility cycle of soybean in calcareous soil,the field experiment is set up to study the effects of acid phosphate fertilizer on soybean growth and yield.The results show that,compared with the blank group,the fresh weight,dry weight and plant height at seeding,meristem,flowering,scab,bulb and matturity stages are higher in soybean fertilized with acid phosphorus fertilizer are increased;The yields of the CK,TMAP and AP groups are 4 528.11,4 863.89,5 254.52 kg/hm2,respectively;The yield and benefit of AP group are 8％and 3 091.23 RMB Yuan/hm2 higher than that of TMAP group,respectively.The application of urea phosphate type acid water-soluble fertilizer is more effective compared with industrial grade monoammonium phosphate.
