Abstract:

To maximize the yield increasing potential of phosphate fertilizer, it is necessary to reduce the amount and increase the efficiency of fertilizer application in middle and south area of Hebei Province. Through field experiments and laboratory tests, the effects of different P application treatments on soil available P distribution, winter wheat yield and yield factors are studied. The results show that (1) compared with the conventional application of phosphate fertilizer, the integration of water and fertilizer could significantly increase the available phosphorus content in the 20-60 cm soil layer; (2) to reduce the base application of solid phosphate fertilizer and adopt the integrated spraying of liquid phosphate fertilizer with water in spring could increase the kernels per spike and 1000-grain weight and increase the yield of winter wheat; (3) on the basis of 90 kg/hm2 solid (P2O5) as appropriate base application of phosphate fertilizer, wheat yield is better by spraying 30 kg/hm2 liquid (P2O5) in spring. Base application of solid phosphate fertilizer (P2O5) and dressing water-fertilizer twice in spring could achieve the application of phosphate fertilizer “downward shift to increase efficiency”.
