在秋末冬初和冬末早春之际,往往因气温骤降而使果、菜、桑、茶等作物的叶、枝、花遭受冻害,轻者生长受到抑制,重者组织坏死。目前各地所采用的防冻方法,主要是熏烟和灌水,这不但麻烦,而且效果差。为此,我们研究成功了较为理想的多效植物防冻剂,现 In late autumn and early winter and early winter early spring, leaves, branches and flowers of fruits, vegetables, mulberry, tea and other crops often suffer frost damage due to the sudden drop in temperature. The growth of light persons is suppressed, and those with severe tissue necrosis. Currently used around the antifreeze methods, mainly fumigation and irrigation, which is not only cumbersome, but also poor results. To this end, we study the more successful multi-effect plant antifreeze, now
