继美国俄亥俄洲园艺科学家们发现在柳树枝条内含有一种能诱导或刺激生根的物质后,我们林场于1985年对此做了试验。 1.我们采取春天刚萌发的柳树枝条,去掉叶芽,剪成3—5cm长的小段,按每公斤枝条加水5公斤的比例在25℃的水中浸泡24小时,取其浸液备试验用(此液即为原液)。 2.取春天刚萌发的杨一小×黑、小叶柞树、枫树、落叶松等枝条,去掉生长点,截取20cm小段,用沙培法栽培,每个树种除设对照外,各取20株分别用原液1.5公斤,
After the horticultural scientists in Ohio, USA, discovered that the willow branches contained a substance that induced or stimulated rooting, we conducted this experiment in 1985. 1. We take the spring has just sprouted willow branches, remove the leaves and buds, cut into 3-5cm long section, according to the proportion of water per kilogram of water 5kg soak in 25 ℃ water for 24 hours, take the immersion test Liquid is the stock solution). Take the spring just germination of a small × × young black, leaf oak tree, maple, larch and other branches, remove the growth point, interception 20cm small section, sand cultivation culture, except for each control set aside 20 strains Respectively with the original liquid 1.5 kg,
