冬小麦是郸城县主要的夏粮作物,常年种植面积86710万平方米左右。小麦产量高低直接影响到郸城县的夏粮生产和农民收入,而施肥管理是小麦增产的关键因素。在对小麦施肥习惯上,农民往往偏施氮肥,而忽视与磷钾肥配合施用对小麦生产的促进作用,从而导致小麦产量不高,以及资源浪费、环境污染、土壤板结等一系列问题。一、试验目的通过本试验,研究探索氮、磷、钾肥配合施用对小麦产量的影响,为小麦高产、高效提供合理的施肥依据。二、材料与方法1.试验材料:化肥利用含氮46%的尿素,含五氧化二磷12%的过磷酸钙,含氧化钾60%的氯化
Winter wheat is the main summer crop in Dancheng County, with an annual planting area of 867.1 million square meters. The level of wheat yield directly affects summer grain production and peasant income in Dancheng County, while fertilization management is the key factor for increasing wheat yield. In the practice of fertilizing wheat, peasants tend to favor nitrogen fertilization while neglecting the synergistic effect with phosphorus and potassium fertilizers on wheat production, resulting in a low yield of wheat and a series of problems such as waste of resources, environmental pollution and soil compaction. First, the purpose of the experiment Through this experiment, to explore the impact of nitrogen, phosphorus and potassium fertilizer application on wheat yield, to provide a reasonable basis for high yield and high efficiency of wheat. Second, materials and methods 1. Test Materials: Fertilizer use 46% nitrogen urea, phosphorus pentoxide containing 12% of the superphosphate, 60% of potassium chloride containing potassium chloride
