培育树苗是一个相当缓慢的过程,过去虽然研制出一些生长激素,但因价恪昂贵,难以大面积推广使用。现介绍两种既经济又有效的方法。 1.牛胆汁液制成树苗生长激素保加利亚的林业专家发明了利用屠宰场的下脚料牛胆汁液制成树苗生长激素。经试验证明,这种牛胆激素水溶液时针叶树种和阔叶树种都有加快种子发芽和提高树苗成活率的作用。 1.阿斯匹林溶液浸泡树苗法据试验,用阿斯匹林溶液浸泡树苗,可提高成活率。方法是,在移栽树苗时,用20 ppm或10 ppm的阿斯匹林溶液作安根水将土浸潮,以后任其自然
Cultivating saplings is a rather slow process. Although some growth hormones were developed in the past, it is difficult to popularize large areas due to the high price. We now introduce two economical and effective methods. 1. Bovine bile made of plant saplings Forestry experts in Bulgaria invented the use of abattoir plant bovine bile saplings made of saplings. It has been proved through experiments that the coniferous and broadleaf species of this kind of bile hormone solution have the functions of accelerating seed germination and improving the survival rate of seedlings. Aspirin solution soaking sapling According to the test, soaking sapling with aspirin solution can improve the survival rate. The method is, when transplanting saplings, with 20 ppm or 10 ppm of aspirin solution as root water soaked soil, let it naturally
