In light of current using situation and drawing on the experience of many scholars researched methods and viewpoints, this thesis made com land, fallow land, orchard, grass land as experimental field in black soil region jlau, which carried out experiment by applying different amounts of n and p fertilization in corn field. by means of collecting the samples of rainfall runoff, erosion silt and surface layer soil before and after rainfall for one year nature precipitation in field, we study the effect of surface runoff on n and p nutrient and fertility degeneration. the results showed : ( l ) there are lots of factors which affect soil erosion and losses of n and p, in which rainfall and rainfall intensity were more important, while rainfall intensity is the most important meteorological phenomena factor

    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。
  2. ( 2 ) irrigating with less water, only when the quantity of irrigating water in a puddle is more than 4000m1, it can spread into 20cm depth where the crop roots are gathered. otherwise, it is hard for the crops to absorb the irrigating water, and the irrigating water is wasting. ( 3 ) the vertical distribution state of n. p. k. is that, n. moves with the irrigating water fast and most of n. gathers in the soil of 30 - 40cm depth ; the moving rules of p. and k. are similar

    （ 3 ） n 、 p 、 k元素在土壤中的垂直分佈狀況為： n素隨滴灌水在土壤中的流動性較強，在30 ? 40cm土層集聚量較大； p素和k素在土壤中運移規律基本相似，都以土表集聚為主，到30 ? 40cm土層， k ~ +含量就接近對照，這說明土表滴灌施鉀肥實際意義不大。
  3. Abstract : the pot - experiment shows that the coated - and mixed - fertilizer applied to rice only once can meet the need of rice in its various growth periods and increase the yield of rice

    文摘:盆栽試驗表明，一次性水稻專用塗層復混肥一次性施用能滿足水稻各生育期的需要，並能促進養分由稻稈向穀粒的轉移，提高成穗率和產量，使用方便，節省勞力，有較好的推廣應用前景。
  4. But the concentration of nh4 + decreased to the very low level in 7 - 10 days after fertilizer was applied

  5. By studying to fertilize in deep and omnibearing lamination to soybean during l993 ~ 1994, the results showed that applying fertilizer in the lamination under ridges according to the regulation of fertilizer needed and the root distribution of soybean should be advantageous to the growth and development of root and plant, increase dry matter accumulation, adjust the factors determining soybean yield and increase yield significantly

    摘要通過1993 ~ 1994年對大豆全方位分層深施肥的研究，結果表明，按照大豆需肥規律和根系分佈部位進行壟下三條分層深施肥，有利於大豆根系、植株生長發育、增加干物質積累，調整產量因素，增產顯著。
