Effects of Different Irrigation Methods on Growth and Yield of Spring Maize in Sandy Area of Yulin City
[Objective] Through revealing the effects of drip irrigation under mulch(MG)
drip irrigation without mulch(DG)
furrow irrigation(GA)
alternate furrow irrigation(JG) and flood irrigation(CK) on the growth and yield of spring maize
we aimed to find out the most effective irrigation method which was suitable for the sandy area of Yulin City in order to provide theoretical support for the development of agricultural water-saving irrigation technology. [Methods] Based on the field experiment data in 2014
statistical analysis and calculation method of water productivity were used. [Results] (1) Under the treatment of MG
the growth and development of spring maize were better than that in other irrigation methods. During whole growth period
plant height
stem diameter and leaf SPAD value in the treatment of MG were higher than that in the treatment of DG
GA and JG
and were significantly higher than that in CK(p<0.05); (2) Under the treatment of MG
the photosynthetic rate
stomatal conductance and water use efficiency of spring maize leaf were greater than the corresponding values in other irrigation methods during whole growth period
and were significantly higher than that in the treatment of CK(p<0.05); (3) Drip irrigation under mulch had significant effects on yield and water use efficiency
the two items were significantly higher than that in other treatments(p<0.05). [Conclusion] Compared with other irrigation methods
the drip irrigation under mulch is the most effective irrigation method for maize in sandy area of Yulin City.
