Different Mechanized Fertilization Methods in Nutrient Utilization and Summer Maize Yield

In the production of summer maize, problems excessive fertilizer input and low utilization rate are common, resulting in waste resources environmental pollution. order to explore optimal fertilization mode a field experiment with eight treatments was designed which sowing were carried out by different machines. The effects two methods, i.e., hole strip fertilization; positions, side-position positive-position depths, 10 cm 15 cm, on maize yield, plant nitrogen, phosphorus, potassium nutrient accumulation, aboveground biomass studied. results show that modes had significant biomass. general, when method used, deep superior.
