  1. 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，菊芋的莖部具有明顯的貯cl ~ - 、 na ~ +能力，在高濃度海水灌溉下菊芋整個植株對k ~ +具有較高的選擇吸收性；菊芋地上部和塊莖產量在30海水處理范圍內，沒有減產趨勢，在50海水灌溉下減產幅度分別為37和32 ；可見，正常自然條件下的海水灌溉，對產量的影響主要和灌溉水的濃度有關，但只有在50處理下才顯著減產，低於50產量並無差異。
