  1. In recent years, the water - saving and control irrigation technique of rice has diverted from plot experimental and demonstration to lare scale. and has got remarkable economic and social benefits. amed at the characteristics of this irrigation area, optimal selection for water - saving techniques of rice, deciding the amout of leaching water and irrigation modles, investigating the adaptability of the water - saving and control irrigation technique in saline land. studying the increase in production mechanism of the technique are important to extend the technique, to better and develop saline land as well as slick spots. according to the results of field experiments, optimization study was conducted on the water - saving irrigation technique of rice in saline land, the effects of different water - saving irrigation techniques on the physiological indexes and yield of rice were systematically analyzed. by using mutiplepurpose fuzzy optimization method, better. water - saving irrigation technique was selector out, that is. the control irrigation technique in rice. the mechanism of it was analyzed from the aspect of the physiological and ecological saving water of rice to provide the implemental process and technical point ; throgh the quantitive analysis and comparision on control irrigation and control class ( flood irrigation ), high production and quality mechanism of the technique was analyzed in terms of physiology indexes of rice, the variation of soil moisture, the pest resistance and the lodge resistance, the change of soil temperature in paddy fields. the yield constitutive factors, the quality of rice and so on. in saline land. control irrigation and intermittent leaching modles were adopted to validate the adaptability of the technique in irrigation of rice in saline land, to analyze rice ' s physiological - ecological indexes and the change of soil salt content under the conditions of control irrigation leaching of rice and and to provide control irrigation and combined modle of intermittent leaching to adapt to different conditions

  2. The main results are following : ( 1 ) the variation of clay / silt ratio can indicate the secondary clay action of dust depositions ; the variations of magnetic susceptibility and total fe content are inferred to be records of the changeable intensity of bio - pedogenesis ; the variations of sr content and rb / sr ratio can indicate bio - pedogenesis, dissolving and leaching action ; the content of total organic carbon ( toc ) can reflect variation of climate and vegetation during soil formation, it indicates the intensity of weathering and bio - pedogenesis ; the content variation of caco3 can show the intensity of dissolving - leaching action and secondary deposit, which was noted as pseudomycilia in pores and fissures in the sediment, so it can indicate the intensity bio - pedogenesis quite well. these proxy indexes also reflect obvious regional difference of pedogenic environment and the intensity bio - pedogenesis ; namely, secondary clay action, dissolving - leaching action and bio - pedogenesis are all much stronger in south than that in north

    實驗結果表明:粘粒粉沙比值能很好地指示粉塵堆積物的次生粘化作用;磁化率和全鐵很好地指示生物風化成壤作用; sr和rb sr比值能很好的指示生物風化成壤作用和淋溶作用;總有機碳( toc )含量的高低,在一定程度上反應了土壤發育過程中氣候和植被狀況的變化,指示著成壤過程中腐殖質化的程度; caco3含量的變化,可以反映了黃土古土壤形成時的風化成壤作用的強弱程度,指示成壤過程中的淋溶作用和次生碳酸鹽化作用;並且各指標所指示的成壤環境和成壤強度存在明顯的區域差異,即渭河流域土壤的生物風化成壤作用、次生粘化作用和淋溶作用均表現出南部強于北部。
