中文摘要以土壤与不同比例堆肥混合培养试验为基础,研究了堆肥对土壤主要营养元素可溶性的影响。对试验结果的统计分析表明,在0.01MCaCl2浸提液中的可溶有机全碳(TOC)在堆肥比例10%时急剧上升;NO3^-和K随堆肥比例的增加而明显增加。TOC在混合物培养75d前明显下降后又上升;NO3^-随培养时间的变化无规律;K随培养时间而下降;P不受堆肥比例及培养时间的影响。
英文摘要Soil analytical results are presented based on soi1 compost incubation experiment and 0.01 M CaC12 as extraction reagent for evaluating solubility of soil macronutrients in a compost amended soi1 with rate of compost an d with incubation time conducted in Faculty of Agricultural and Applied BidogicaI Sciences,Gent University,Belgium.
The experiment designintwofactors:0% ,0.1% ,0.5% ,1% ,5% ,10% of compost added to the soil for assessing the influence of amoHnt of compost on the solubility of macronutrients—C,N,P an d K;15,30,45,60,75,90 days of incubation after~qflendmerit of the co mpost for evaluating the influence of time on the s。lubility the above macronutricnts.
Owing to the biological statistical analysis pH slightly increased with rate of compost,but gently decreas。d with time;there are significant increase of total organic carbon(TOC) when 10% ofcompostwas added tothe soilin0.01 M calcium chloride(CaCI2);NO;andK was incressed pronouncedly with incremen t of compost.TOC w0s decreased significantly before 75 days of incubation and increased a{ter 75 clays of incu bation.The changge of NO;wagirregular an d K decreased with incubation time.The soluble P was not influenced by the mte of compost and 1ncuhation time.
