采用田间试验的方法,对于连作5年的温室黄瓜和连作4年的温室番茄,进行活性腐植酸不同组合的施肥试验研究.结果表明:活性腐植酸能够降低土壤容重,提高田间持水量;增加土壤有机质和有效养分含量,提高保护地土壤pH值,减缓土壤酸化,降低土壤含盐量;还能够提高土壤微生物数量,提高土壤酶活性、土壤温度和土壤呼吸速率.

Field experiments were conducted to study the effects of high active humic acid on properties of soil which was planted cucumber continuously for 5 years and tomato continuously for 4 years in greenhouse, respectively. The results showed that high active humic acid could reduce soil bulk density, and raise field capacity. High active humic acid could increase the contents of soil organic matter and available nutrients,raise soil pH, slow down soil acidifica-tion, and reduce soil salt content. High active humic acid could also raise the contents of soil microorganisms, raise soil enzyme activities, soil temperature and respiration rate.
