| 中文摘要: |
| 于2002年在半干旱的山东莱州地区,利用海水资源进行了大田灌溉菊芋的试验,结果如下:(1)0～60cm土层内,Na-、Cl-明显地向土壤底层迁移;(2)菊芋的茎部具有明显的贮Cl-、Na-能力,在高比例(海、淡水体积比)矿化水灌溉下菊芋整个植株对K+具有较高的选择吸收性;(3)菊芋地上部和块茎产量在灌溉水中海水比例为30%的情况下,没有减产趋势,在50%海水灌溉下减产幅度分别为37%和32%;(4)利用海水资源对菊芋进行灌溉不影响其块茎中菊糖的含量,菊芋块茎中菊糖含量范围为40%～65%。 |
| 英文摘要: |
| The field experiments were carried out in Laizhou, Shandong province in 2002 to study the effect of seawater irrigation on Helianthus tuberosus L.. The results were as below: (1)Na- and Cl- leached in the 0～60 cm soil layers; (2)The stems of Helianthus tuberosus L. had the ability of containing high contents of Na- and Cl-, and the whole plants absorbed selectively K+ in high proportions of seawater irrigation; (3)The shoot and tuber yields of Helianthus tuberosus L. didn’t decrease clearly when the seawater proportion was less than 30%, and they decreased by 37% and 32% at the 50% seawater irrigation in contrast to freshwater-irrigation; (4)The inulin contents in tubers of Helianthus tuberosus L. were not affected by seawater irrigation, being in the range of 40%~65%. |
