土壤改良剂哈莫菲纳(HOMOFINA),是比利时生产的以石油副产品沥清为原料加入表面活性物质制成的一种乳剂。据介绍该改良剂在农业上应用具有改良土壤物理性状、促进团粒体形成、增强土壤抗蚀性、防止水土流失等作用。基于这些特点,我们于1934年在苹果幼树上进行试验,观察其对苹果树生长的影响。试验地选在没有灌溉条件的阳坡
Soil improver HOMOFINA is an emulsion produced in Belgium by adding bitumen, a petroleum by-product, as a raw material to surface-active substances. It is reported that the improver used in agriculture has the effect of improving soil physical properties, promoting the formation of aggregate, enhancing soil corrosion resistance and preventing water and soil loss. Based on these characteristics, we conducted experiments on young apple trees in 1934 to observe their effects on apple tree growth. The test was chosen on the sunny slope without irrigation conditions
