Abstract

The production of humic substances and their retention capacities for phosphorus and calcium released during composting of wheat straw with two types of low-grade rock phosphate were examined. Relative quantities of humic acids increased with increase of composting time, while fulvic acids production decreased after 30 days of composting. The addition of both Mussoorie and Hyperphos retarded humic acids production and enhanced fulvic acids production. Molasses incorporation had no effect on humic acids but increased fulvic acids production. The production of humic acids and their retention capacity for P and Ca were greater in the presence of Mussoorie phosphate than in the presence of Hyperphos, but fulvic acids formation was higher with Hyperphos. About 80–85% P and 90–95% Ca retained by the total humic substances were found in the fulvic acids fraction.

秸秆堆肥中的腐殖质与磷矿
研究了小麦秸秆与两种低品位磷矿混合堆肥过程中腐殖质的生成及其对释放的磷和钙的保留能力。腐植酸的相对产量随堆肥时间的延长而增加,腐植酸的相对产量在堆肥30 d后下降。Mussoorie和Hyperphos的添加延缓了腐植酸的产生,增强了黄腐酸的产生。加入糖蜜对腐植酸没有影响,但增加了黄腐酸的产量。腐殖酸的生成和对磷和钙的保留能力在有机磷存在下比在高磷存在下更大,而富腐酸的形成在高磷存在下更高。腐殖酸组分中总腐殖质中磷和钙的残留量分别为80 ~ 85%和90 ~ 95%。
