| Abstract: | The orthogonal test is conducted to analyze the drip irrigation program of the winter wheat in Ningxia Yellow River irrigation district.The results show that the fertigation can enhance the absorptive capability of the winter wheat on the water and fertilization.The change of soil water content(0~40 cm),EC and pH value is the zigzag,respectively.The winter wheat yield and plant height increase with the increase of irrigation amount and times.And the effects of the irrigation amount and times on the winter w... |
