从1976～1983年,经过连续7年的田间试验, 证明用腐植酸钠作腐烂病疤保护剂,有利于伤口愈合,减少病疤重犯。1982年在北戴河大面积田间试验观察,涂抹腐植酸钠处理的,病疤复发率为4.5%,涂砷平液处理的为8.8%,清水对照的为17%;平均单侧愈合量,腐植酸钠处理的为11.0毫米,砷平液处理的为6.1毫米,清水对照的为6.5毫米。多年多点试验以及在山海关园艺场两年试验结果,与上述趋势相同。 From 1976 to 1983, after seven consecutive years of field trials, sodium humate was proved to be a protective agent against rot disease, which is good for wound healing and reduces the recurrence of scarring. In 1982, a large area field trial in Beidaihe showed that the rate of recurrence of scar was 4.5%, that of sodium arsenate solution was 8.8% and that of fresh water was 17%. The mean unilateral heal volume, sodium humate treatment Of 11.0 mm, 6.1 mm for arsenic flushing solution and 6.5 mm for clear water control. Many years of multi-point test and two years in the Shanhaiguan horticultural field test results, the same trend with the above.
