Effect of the Frequency of Fertilizer Application on the Grain Yield and Growth of Spring Wheat under Drip Irrigation
Abstract：The field experiments were carried out under drip fertigation tO study the effects of frequencies of fertilizer application on the spring wheat growth and yield. Under the conditions of the same total fertilizer and irrigation water regime, three frequencies of fertilization treatments （4 times, 7 times, 10 times） were set in the whole growth stage of spring wheat. The plant height, tiller number and leaf area index were observed in spring wheat growing stages, and the theoretical grain yield of spring wheat was measured. The experiments results indicated that the growth indicators of spring wheat were promoted by increasing fertilizer than by irlcreasing the frequencies of fertilizer application in the vegetative growth stage of spring wheat; in the reproductive growth stage of spring wheat, the increasing frequencies of fertilizer application promoted the growth indicators of spring wheat much better.
