Abstract:
      According to the principle and recipe of CULTAN(Controlled uptake long term ammonium nutrition)presented by Professor Sommer,combined with local fertilizer resource and fertilizer application,the effect of fertilizers controlled by root growth and traditional fertilizers on wheat growth development and quality was studied in Linfen.The results showed that the treatments of fertilizer controlled by root growth with the mixture of ammonium sulfate,DCD and urea as fertilizer increase water absorption rate,stable time and valorimeter value of wheat dough and the content of available N in the soil profile,compared with the traditional fertilizer.Therefore,in high-gluten winter wheat planting regions,extending usage of CULTAN can achieve harmony between yield and quality.
