  1. Phosphorus absorbed and immobilized in rhizosphere was less than that of in root zone and unroot zone. 2. the isothermal adsorption curve of each can be partition into two parts. phosphorus adsorption amount and phosphorus consistency slope in equilibrium solution are relatively higher than the slope of phosphorus adsorption amount and phosphorus consistency when fertilizer amount added increasing continuously

    土壤的等溫吸附曲線可分成兩個部分：當土壤平衡溶液濃度很低時，磷的吸附量與（ x ）磷的平衡溶液濃度（ c ）的曲線斜率較大；當施肥量不斷增加后，土壤平衡溶液濃度也會隨之不斷增加，曲線斜率變小。
  2. 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。
  3. Some results are as follows : the highest concentration of nh 4 + - n in leachate is closely related with urea quantity applied at 20cm depth, but not different significantly related at 60cm and 120cm depth

    其試驗結果如下：在不同尿素施用量情況下，各處理中20cm處滲漏液中nh _ 4 ~ + - n最高濃度值與施肥量密切相關，但60cm和120cm處滲漏液中nh _ 4 ~ + - n濃度與施肥量關系不大。
  4. Using plots with water and fertilizer fully controlled, the effect of photosynthetic characteristic and yield under different treatments of water and fertilizer coupling was investigated. the result showed that photosynthetic rates are different among treatments of water and fertilizer coupling, and the change of stomatal conductivity is the same as photosynthetic rat. there is almost no influence on evaporation rate and cellular co2 concentration the combination of fertilizer and manure under natural rainfall is beneficial to the maintenance of photosynthetic rate during grain filling, thus results in highter yield and good quality. however, the coupling of fertilizer and manure with sufficient water results in the decline of photosynthetic rate and stomatal conductivity, the yield decreased indicating there has a balance ratio between water and nutrients ( fertilizer and manure ) supply. the study proposed that the optimum management to exploring yield and qlality potential is the combination of fertilizer and manure application with no irrigation

    利用可精確控制水分條件的水肥平衡場，在不同水肥耦合處理的條件下，研究了水肥耦合對玉米光合特性及產量的影響，結果表明:不同水肥耦合處理的條件下，玉米的光合速率有所不同，氣孔導度的變化與光合速率的變化表現基本一致，而對蒸騰速率、細胞間co2濃度影響不大.其中，在自然降水條件下，有機肥和無機肥的配合，有利於玉米子粒灌漿期維持較高的光合速率，表現出良好的產量潛力.充足水條件下，有機肥和無機肥的配合，光合速率及氣孔導度表現較低，表現產量有所下降，說明供水量與施肥量之間有一個平衡系數.表明黑龍江省北部黑土區自然生態條件下，為充分發揮玉米的產量潛力，最佳的管理措施是增施無機肥和有機肥的配合
  5. But the concentration of nh4 + decreased to the very low level in 7 - 10 days after fertilizer was applied

    而田表水層中銨態氮濃度在施肥后第7 ? 10天左右均降至很低水平。
