腐植酸钠的喷洒,能使作物增产。其原因主要是对作物关键时期起刺激作用,促进植物的呼吸作用以及各种酶的转化,并促进植物对营养物质的吸收。由于在溶液状态使用,用量少、成本低,有推广价值。我们考虑能否应用在幼树上,促进幼林生长。带着这个问题,于一九八○年春季开始,在高丰大队林场,使用不同浓度的腐植酸钠溶液,对造林后一、二年的杉树幼林进行了叶面喷雾试验,连续两年的观察,证明效果显著。
Sodium humate spraying, can increase crop yield. The main reason is to stimulate the key period of the crop, to promote the respiration of plants and the transformation of various enzymes, and promote the plant’s absorption of nutrients. As a result of the use of the solution, with less, low cost, promotional value. We consider whether it can be applied to saplings to promote the growth of young forests. With this problem, foliar spray tests were conducted on the young cedar of one or two years after afforestation, using the different concentrations of sodium humate solution at the Gaofeng fleet farm in the spring of 1980. For two consecutive years The observation shows that the effect is remarkable.
