ABT(生根粉,增产灵)是高效广谱复合型的植物生根促进剂和生长调节剂。首先在林木、果树、花卉的扦插移栽上应用,近年来在农作物和经济作物上广泛应用,增产幅度10.2—145.3%,投产比为1:45.6—189.6。在牧草上应用报道甚少,1985年起我所进行 ABT 在7种多年生牧草上的应用试验,结果表明 ABT 能促进牧草种子发芽和幼苗生长,提高叶绿素含量和光合强度,增加干物质积累,增产效果显著,同时 ABT 无公害,使用安全,亦能增强牧草耐旱抗病能力,提高牧草品质。四年来生产实践说明,采用拌种处理最为适宜,方法简便易行,增产17.42—87.6%,投产比为1:45.6—133.0,取得了明显的经济效益、社会效益和生产效益,为我国牧区人工草地建设和种子繁育开辟了新的增产途径,可以大面积推广应用。
ABT (rooting powder, Zeng Ling) is a broad-spectrum composite plant rooting accelerator and growth regulator. First of all in the trees, fruit trees, flowers, cutting transplanting application, in recent years, widely used in crops and cash crops, yield 10.2-145.3%, production ratio of 1: 45.6-189.6. Application in pasture has little been reported. Since 1985, ABT has been applied in seven perennial grasses. The results showed that ABT can promote seed germination and seedling growth of forage grass, increase chlorophyll content and photosynthetic rate, increase dry matter accumulation and increase yield The effect is remarkable. At the same time, ABT is pollution-free and safe to use. It also enhances the ability of drought-resistant and disease-resistant grass and improves the quality of pasture. Four years of production practice shows that the seed dressing treatment is most suitable, the method is simple and easy, yield 17.42-87.6%, put into production ratio of 1: 45.6-133.0, achieved significant economic benefits, social benefits and production efficiency for our pastoral labor Grassland construction and seed breeding opened up a new way to increase production, which can be widely applied.
