苏联列宁格勒林业技术大学的科技人员最近发现许多联氨卤化盐,对蕃茄、土豆有明显的增产作用,对于林木效果也很佳.经0.1—2%浓度联氨二氯乙烷液浸种一昼夜处理的松树种子7天的发芽率比对照增加3—19%,云杉种子发芽率提高7—15%;用1—2%浓度联氨乙酸丙烯酰胺液浸种处理一昼夜,可使云杉种子发芽率增加3—13%,烂种数量比对照减少5倍。2%浓度液的联氨乙酸丙烯酰胺液浸泡松树种子,发芽率可增加7%,并能促进苗木提早展叶。
Researchers from the Leningrad Grove University of Technology in the United States have recently discovered that many hydrazine halides have significantly increased yield on tomatoes and potatoes, and are also very effective in forest use. Seed soaking in 0.1-2% conc. Of dithionite for a full day and night The germination rate of the treated pine seeds increased by 3-19% and the germination rate of the spruce seeds increased by 7-15% compared with the control. The sprout seeds could be germinated by soaking the seeds with 1-2% conc solution of hydrazine and acrylamide for one day The rate increased 3-13%, the number of rotten species decreased 5 times than the control. 2% concentration of liquid ammonia-linked amino acid solution soaked pine seed, the germination rate can be increased by 7%, and can promote seedling leaf early exhibition.
