Study of an Examine Way of the Humic Acid Class Liquid Fertilizer's Biology Action
摘要/Abstract
摘要：
报道腐植酸类液肥生物活性的3种检验方法: 1)用大蒜水培法测定促进作物生长;2)用菜豆角或黄瓜的叶片测定气孔开张度;3)用棉花黄萎病菌和枯萎病菌平皿培养法作抑菌和杀菌试验.这些方法的效果很显著并与腐植酸浓度相关
Abstract：
To introduce three class examine way of the humic acid class liquid fertilizer's biology active: 1) Examine pomate crope grow by a method of the garlic in the water; 2) Examine open or close stoma by the kidney been or cucumber beaf; 3) Examine restrain and kill death Verticillium albo-atrum R et B or Fusarium oxysporum f.vasinfectum (ATK) Snyder S.Hansen.
