本文通过对玉米、大豆施用锰肥肥效及不同剂量的试验研究。证明玉米、大豆施用锰肥具有明显的增产作用,可使玉米亩增产20～50公斤,增产率在10～20%,大豆可增产15～18公斤,增产率在12%左右。从而为我县主要土壤黑钙土和黑土上玉米、大豆施用锰肥确定最佳施用剂量和方法,为锰肥大面积推广应用提供可靠的理论基础和科学依据。
In this paper, corn and soybean fertilizer application of manganese fertilizer and different doses of experimental study. Proved maize, soybean application of manganese fertilizer has a significant increase in yield, can increase yield of corn acres 20 to 50 kg, 10 to 20% increase in yield, soybeans can increase 15 to 18 kg, the rate of increase in about 12%. So as to determine the best dosage and method of application of manganese fertilizer for the main soil of China Chernozem and black soil corn, soybean fertilizer, provide a reliable theoretical basis and scientific basis for the promotion and application of large area of manganese fertilizer.
