摘要
用磁化水浸泡稻种可明显地增强稻种的吸水能力,促进萌发,提高发芽势及发芽率。用磁化水培育稻苗显著地促进了稻苗对N、P、K的吸收,从而导致幼苗根数、茎粗、百株干重及分蘖率的增加。用磁化水灌溉水稻增加了叶片的叶绿素含量、提高了硝酸还原酶活性和束缚水含量、降低了叶片细胞膜在低温下的透性,即增强了水稻的抗逆能力。磁化水改变了稻叶与稻根中的过氧化物酶同工酶谱带的数目。用磁化水灌溉,具有显著的增产效应,其增产幅度为13～23％。在所有磁化水处理中,以0.27T(特斯拉)的效果最佳。
Magnetic water treatment has significantly increased the water-absorbing capacity, germinating energy and percentage of rice seeds and the N.P.K. absorbing ability of seedlings. Thus, root quantity, stem thickness, 100-dry-plant weight and tillering rate hove been increased.Magnetic water has also increased chlorophyll content, nitrate reductase activity of leaves but decreased the permeability of cell membrane at low temp-erature.Magnetic water has also strengthened the hardiness of the seedlings, changed the band number of peroxdase Isozyme in seedling roots and leaves, and significantly increased the yield (14-23%) . Of all the treatments, the effect of 0.27T magnetic water is the best.
