Wheat Optimized Fertilization of High Yield Field with Returning Whole Stalks into the Soil in Huang-huai-hai Plain

Abstract

According to wheat fertilizing plan doing not fit in with returning whole stalks into the soil cultivation in Huang-Huai-Hai Plain, the text carried a study on the relationship between fertilizer amount and yield, by “3414†experimental design. The text set up the highest yield and the highest economic benefit fertilizing plan separately. Though the yield of the most economic fertilizing plan was lower than that of the highest yield fertilizing plan by 140.13kg/hm2, but the net income was higher than that of the highest yield fertilizing plan by 490.92RMB/hm2. The yield of the most economic fertilizing plan was higher than that of peasant normal fertilizing plan by 684.54 kg/hm2, and also the net income increased 1109.72RMB/hm2 by 6.7%.
