Abstract
The blind-ear as a Cu deficiency symptom in wheat on upland soils in the hilly area of Zhejiang Province was discussed in this paper. Through 3 years of field experiments, it was elucidated that blind-ear in wheat plant appeared due to the low level of available Cu in the soils, and the critical value 3 mg / kg for total Cu in the plant at grain filling stage and 1 mg/ kg for available Cu (0.1 M HCl) in the soils. A basal dressing of 30 kg / ha of Cu sulfate to the soils could completely eliminate Cu deficiency symptoms, obtain normal grain yield and have residual effect for at least 3 years.
