摘要
本文研究了磁化水对水稻秧苗素质的影响及其机理。磁化水显著地促进了秧苗地上部与地下部生长,增加了秧苗根数(0.2—19.5％),根长(0.8～60.9％),株高、叶数、茎粗、百株干重(2.7—9％),分蘖率(7—21％)以及提高了水稻的抗逆能力。磁化水壮秧的原因与硝酸还原酶活性提高,叶绿素含量、束缚水含量增加,N、P、K养分吸收加快以及细胞膜透性下降,叶片保水能力提高有关。
This paper deals with the effects of magnetic water on the quality of Rice seedling and inquires into the mechanism. The growth of Rice seedling both above and under ground was significantly promoted by magnetic water, it appeared to increase the root numbers(0.2-19.5%), root length(0.8-60.9%), plant height, leave numbers, stem thickness, 100 dried plants weight (2.7-9%)percentage of tiller(7-21%),and the Rice seedlings stress resistance was increased too. The cause of magnetic water promoting the quality of Rice seedling is attributable to the increase of nitrate reductase activity, retaining water ability of leaves, chlorophyll content, bound water, absorption of N. P. K and the decrease of Permeability of cell membrane.
