  1. Effects of diverse environmental factors on the growth rate ( od4oo ) and nitrogenase activity ( ara ) of the strain w12 hi nitrogen - free culture were investigated in our experiments. the results implied that the strain w12 could easily adapt to different cultural conditions : it could use various carbon sources ( especially glucose, sucrose, malic acid, mannitol ), propagate quickly and fix nitrogen at a temperature range of 15 ? to 40 ? and at 25 - 35 ? for optimum, at a ph range of 4 to 8. 5, at a saline concentration range of 0. 01 % to 1. 5 % ; low nlv " concentration had little effect on its nitrogenase activity. ara could also be detected when it grow in the culture media with 5mmol / l ntv "

    W12菌株對環境因子的適應性研究：無氮培養條件下，測定溫度、碳源、酸堿度、滲透壓對w12生長及固氮能力的影響，結果表明，在15 - 40下均能生長並表達固氮酶活性，其最適生長及固氮的溫度為25 - 35 ；能利用葡萄糖、蔗糖、蘋果酸、甘露醇等多種碳源生長並固氮，當培養基中同時存在蔗糖和蘋果酸時，細菌生長和固氮活性最強；在偏酸和偏堿的條件下（ ph4 . 5 - 8 . 5 ）均能保持較強的生長勢和較高的固氮酶活性，並能通過調節自身代謝平衡並適應環境的酸、堿性變化，使培養液趨于中性：能耐受較高的滲透壓，培養液中卜、 5 naci濃度對其生長和固氮酶活性影響不大，當naci濃度升至2時，菌株的生長勢及固氮酶活性才有所下降：低濃度的鉸對其固氮酶活性影響不大，在0
  2. But, when the total water quantity is reduced 30 % of present average amount in the 2010, the total salinity of groundwater will have significant increase in the different period ( pre - summer irrigation, post - summer irrigation, pre - autumn irrigation and pre - freezing up of soil four periods ). the water quality will be likely to deteriorate ; in addition, the prediction models of soil moisture and saline concentration are established

    通過試區土壤水分、鹽分的bp與rbf模型的模擬與檢驗，預測了2005年、 2010年夏灌前、夏灌后、秋澆前與封凍前的土壤水鹽狀況，得出上壤水分隨著灌水量的減少呈下降趨勢，而土壤鹽分在淺層與中層呈現出不同的結果： oa
  3. The saline concentration in the 0 - 40cm layer will produce desalination trend in the 2010. however, the saline concentration in the 40 - 70cm will be slightly accumulated

    總體上節水改造工程對灌區淺層土壤鹽堿化改善與防治有積極效果，但中層仍存在潛在鹽漬化的可能。
  4. The aim of this experiment was to show the characters that salt - alkaline mixed stress on plant and the correlativity between saline stress and alkaline stress. seedlings of sorghum ( changbang 128 ) were stressed with 28 kinds of mixed salt which were composed of nacl, na2so4, nahco3 and na2co3 at various proportions and were different in salinity and alkalinity each other ( the range of total salt concentration 50 - 300mmol / l and ph 7. 12 - 11. 43 )

    為揭示鹽堿地中實際存在的混合鹽堿脅迫對植物的脅迫作用特點以及鹽脅迫與堿脅迫間的相關性，本實驗以c _ 4植物高粱（昌棒128 ）幼苗為研究對象，將nacl 、 na _ 2so _ 4 、 nahco _ 3及na _ 2co _ 3按不同比例混合併對苗齡四周的高粱幼苗進行混合鹽堿脅迫處理。
  5. Based on five years regional water - salt monitoring data and related hydrological and weather information in the smaller scale experiment zone ( shahaoqu ), the regional water - soil ( salt ) environment regime including grounder water table depth, water quality, superficial layer ( 0 - 40cm ) and middle layer ( 40 - 70cm ) soil moisture and saline concentration are simulated, tested and predicted using bp model. at the same time, the rbf model is be used to calibrate the results of bp

    以一個小尺度試驗區的多年區域水鹽監測資料及水文氣象資料為建模依據，對試區非凍期（作物生長期）的地下水位、地下水質、土壤水鹽（ o - 40cm ， 40 - 70cm ）的水-土（鹽）環境狀況進行了較為深入全面的模擬預測，並進行了rbf模型預測結果的對比。
