最近几年,我国报刊上出现了关于磁化技术诱发非豆科作物结瘤、固氮问题的争论,在农业科技界引起酱遍的关心和注意,本文以黄瓜为试验材料,证明一定剂量的磁化处理有促进黄瓜植株鲜重增加,生长健壮的作用,但未观察到磁化诱导黄瓜植株结瘤、固氮现象。试验还首次证明根结线虫可以将根瘤菌引入黄瓜根结中,但进入黄瓜根结中的根瘤菌不能正常表达原有的固氮活性。 In recent years, the debate on magnetization induced non-leguminous crops nodulation and nitrogen fixation has appeared in the press in our country, which has caused the concern and attention in the field of agricultural science and technology. In this paper, cucumber was used as the experimental material to prove that a certain dose of magnetization Cucumber plants to promote fresh weight gain, robust growth role, but no magnetization induced cucumber plant nodulation, nitrogen fixation. The experiment also proved for the first time that root-knot nematodes can introduce rhizobia into the cucumber root knot, but rhizobia entering the cucumber root knot can not express the original nitrogen fixation activity normally.
