舟山市发展海水灌溉农业初探 - My experiment can mostly include two sections : the first one was a pot experiment which was carried out in the greenhouse to study the physiological responses of helianthus tuberosus l . seedlings to salt and water stress ; the second one was a field experiment which was carried out in laizhou , shandong province to study the effects of seawater irrigation on helianthus tuberosus l . and soil
本试验由温室盆栽耐盐耐旱试验和大田海水灌溉试验两大部分组成：温室盆栽试验主要通过砂培的方法，研究了幼苗期菊芋在盐分和水分胁迫下的生理反应；大田试验在半干旱的山东莱州地区进行，研究了海水灌溉对菊芋及其土壤的影响。 - The stem of helianthus tuberosus ( l . ) had the ability of containing high contents of na + and cl - , and selectively absorbed k + in high proportions seawater irrigation ; the above and tubers yields of helianthus tuberosus ( l . ) had n ' t decreased until at the 50 % proportions seawater irrigation where the yields decreased by 37 % and 32 % in contrast to freshwater - irrigated . it meant that through natural weather , reduction of yields was occurred by salinity of irrigation water but the reduction was not significant until the proportions of seawater in irrigation water were the same as 50 % or above it
海水灌溉下，菊芋的茎部具有明显的贮cl ~ - 、 na ~ +能力，在高浓度海水灌溉下菊芋整个植株对k ~ +具有较高的选择吸收性；菊芋地上部和块茎产量在30海水处理范围内，没有减产趋势，在50海水灌溉下减产幅度分别为37和32 ；可见，正常自然条件下的海水灌溉，对产量的影响主要和灌溉水的浓度有关，但只有在50处理下才显著减产，低于50产量并无差异。 - 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，耕层土壤中盐分含量受降雨量影响很大，足够的降雨条件下，盐分不会积累，降雨量较低时，盐分积累明显，但在50海水处理下趋于平衡状态；耕层土壤sar值的变化情况和盐分含量变化情况相一致，在灌溉水中海水浓度大于50时有所下降；土壤中主要盐离子为cl ~ -和na ~ + ， 0 - 60cm土层内， na ~ + 、 cl ~ -明显的向土壤底层迁移，其在土壤中的含量受降雨影响显著，而ca ~ ( 2 + ) 、 mg ~ ( 2 + )和k ~ +在土壤中迁移能力较低，其含量受降雨影响较小； 0 - 60cm层次土壤盐分的纵向分布在降雨量较低的条件下主要受灌溉水中海水浓度的影响，而在降雨充分的条件下，地面覆盖程度成为重要的影响盐分和水分胁迫下菊芋的生理响应及其海水灌溉研究因子之一。
