針對當前黑土利用現狀,本文借鑒眾多學者的研究方法和觀點,在吉林農大黑土區選擇利用方式不同的玉米地、休閑地、果園、草地,在玉米區進行了不同數量的施肥,通過野外試驗,採集一年自然降雨產流及泥沙樣品,同時採集降雨前後的耕層土壤樣品,研究了黑土區地表徑流對氮磷養分特徵及肥力退化的影響,結果表明:土壤侵蝕和氮磷的流失受諸多因素的影響,降雨量、降雨強度是重要因子,而降雨強度是影響農田地表徑流養分流失的最重要的氣象因子,特別是暴雨,暴雨徑流中氮磷濃度較平時高得多;隨作物生長,覆蓋度逐漸增加以及不同利用方式下表現的覆蓋度差異,氮磷流失都表現為顯著的差異。Eng. ) 1. know the fertilizers ( the appearance, properties, physical and chemical nature which includes the organic and inorganic fertilizers ) ; 2. determining the quality ( three major elements of the fertilizers ) and quantity ( the content of the moisture, nitrogen, phosphorus, and potassium ) of chemical fertilizer ; 3. the fertilizer composition expresses and calculation of the amount of application ; 4. it is cultivated in a pot or nutrient solution to test fertilizer effects ; 5. observe plant body : besides observing one ' s own test cultivated in a pot, and another diagnose the picture is for comparing ; 6. making of the compost
