利用腐植酸作肥料,是土壤和农业化学方面研究的新成就。腐植酸可以从泥炭、廐肥、褐煤等物中获得。根据现有资料的介绍,腐植酸是一种生理活性物质,能加强植物新陈代谢中的酶类活动,帮助植物增强呼吸,促进生长发育,使土壤微生物活跃,改良土壤营养状况。为了把腐植酸运用到林业生产中去,今年我们作了一些测定腐植酸作用的小型试验。现把初步获得的结果,介绍如下:
Using humic acid as a fertilizer is a new achievement in soil and agrochemical research. Humic acid can be obtained from peat, fertilizer, lignite and other objects. According to the available information, humic acid is a kind of physiologically active substance, which can enhance enzymes activities in plant metabolism, help plants to enhance respiration, promote growth and development, make soil microorganisms active and improve soil nutrient status. In order to apply humic acid to forestry production this year we made a few small trials to determine the effect of humic acid. The initial results are presented below:
