But on the later condition the trend of accumulation turned to be stable in the w3 treatment ( vseawater / v pure water = 1 ) - in root zone soil, variation of sar value accorded with total salt accumulations and sometimes decreased at the treatment where the v seawater / v pure water > 1. contents of cl - and na + which were the main ions and leached obviously in 0 - 60cm soil were greatly influenced by rainfall, but the rainfall did not affected the contents of ca2 +, mg2 + and k + whose ability of leaching is worse than that of cl - and na + in the root zone soil obviously. the vertical distribution of salt ions in the 0 - 60cm soil were mainly affected by the ratio of v seawater / v pure water in the irrigation water on the condition of not enough rainfall, but on the cont
海水灌溉下，耕層土壤中鹽分含量受降雨量影響很大，足夠的降雨條件下，鹽分不會積累，降雨量較低時，鹽分積累明顯，但在50海水處理下趨于平衡狀態；耕層土壤sar值的變化情況和鹽分含量變化情況相一致，在灌溉水中海水濃度大於50時有所下降；土壤中主要鹽離子為cl ~ -和na ~ + ， 0 - 60cm土層內， na ~ + 、 cl ~ -明顯的向土壤底層遷移，其在土壤中的含量受降雨影響顯著，而ca ~ （ 2 + ） 、 mg ~ （ 2 + ）和k ~ +在土壤中遷移能力較低，其含量受降雨影響較小； 0 - 60cm層次土壤鹽分的縱向分佈在降雨量較低的條件下主要受灌溉水中海水濃度的影響，而在降雨充分的條件下，地面覆蓋程度成為重要的影響鹽分和水分脅迫下菊芋的生理響應及其海水灌溉研究因子之一。 -
Therefore, it is useful to decrease nitrogen application amount or even with n application in split time so as to decrease the n loss and leaching in the paddy - field. 6. to define and calculate even productivity of nitrogen in the surface water - body ' of paddy field ( epnw ), marginal productivity of nitrogen in the surface water ( mpnw ) and elasticity coefficient of nitrogen in the surface water ( ecnw ), indicated that epnw and ecnw increased with n application amount increase, however mpnw has no the rule
6 .定義和計算水氮平均產生力、水氮邊際產生力和水氮產生力彈性系數，表明水氮平均產生力和水氮產生力彈性系數是隨著施氮量的增加而增加的，而水氮邊際產生力隨施氮量的增加並沒有表現出明顯的增加趨勢。 -
Study an effect of using sulfur - removal waste residue ( the vice - product produced by sulfur - removal device of the factory using coal as energy resource to absorb oxidizing sulfur, whose mainly composition is gypsum ) as an amendment to the alkali soil in theory. with certain water as leaching requirement leaching soil column indoor employed with certain quantity sulfur - removal waste residue after collecting and analyzing representative soil sample. collecting and analyzing the filtrate, then calculate the data and speculate the result to guide the field production
本文重點是對煤煙脫硫廢渣（利用煤炭作為能源的工廠的除硫裝置消除硫氧化物后的副產物，主要成分為石膏）改良堿土進行理論研究，方法上以室內土柱淋溶模擬為主，採集有代表性的堿土並分析其成分后，採用小水量定額灌洗，收集分析濾液化學成分，進行推理分析計算並指導田間的生產實際。 -
Nitrate content of rape and coriander increased with higher nitrogenous fertilizer application and lower water supply. nitrogen leaching in the soil increased with higher nitrogenous fertilizer application and water supply in column and micro - plot experiments, especially on higher irrigation and higher nitrogenous fertilizer. there was little nitrogen leaching when n application was below 135 kg / hm2, but n use at a rate of 270 kg / hm2 increased nitrogen leaching in the soil
在一定的施氮量下，硝態氮的積累峰值隨著灌水量的增加而下移， 150mm灌水量下田區試驗和模擬土柱試驗0 100cm土體內硝態氮的積累峰值分別出現在0 30cm和50 70cm ； 250mm灌水量下分別出現在40 60cm和60 80cm ； 350mm灌水量下田區試驗中0 100cm土體硝態氮沒有出現峰值，而模擬土柱試驗在80 100cm則有明顯的積累。 -
As the increase of water added, the level of no3 - n in soils was decreased, in comparison with fif, it is concluded that dif significantly decreased the leaching loss of urea - n from soil, and increased the available nitrogen in soil
總之，與澆灌施肥相比，滴灌施肥顯著地減少了尿素態氮的淋溶損失，增加了土壤中有效態氮的含量。 -
The structure of fertilizers was studied by scaning electronic microscopy ( sem ), and the nutrient release characteristics were studied using water dissolution rate method and soil column leaching method. [ result ] the 24 hours n water dissolution rates of sapcus were 18. 22 % - 83. 87 %, and n accumulated leaching rates in four weeks were 40. 91 % - 65. 38 %, which decreased by 5. 21 % - 40. 68 % compared with that of urea under the same experiment conditions
