| 中文摘要: |
| 通过测定果树枝、菌糠、中药渣、发酵猪粪垫料以及稻壳/木屑不同配比垫料内腐殖质及其组分含量,研究育肥猪一个生长周期内猪发酵床垫料中腐殖质及其主要组分胡敏酸、富里酸的形态变化特性.结果表明:初始中药渣垫料内胡敏酸与富里酸总碳量及富里酸含量最高,初始菌糠垫料内胡敏酸含量、胡/富比及胡敏酸E4/E6比值最高.在育肥猪一个生长周期内,除中药渣垫料外,包括稻壳/木屑不同配比的其他垫料内胡敏酸与富里酸总量表现为前三个月增加而后降低,富里酸表现为前两个月增加而后下降;除菌糠垫料外,包括稻壳/木屑不同配比的其他垫料胡敏酸均表现为持续增加,所有垫料内胡敏酸E4/E6值均下降.饲养三批猪的稻壳/木屑垫料内腐殖质及其不同组分含量以及胡敏酸E4/E6值均相对较低.中药渣、菌糠、果树枝与发酵猪粪垫料同一取样时期垫料内胡敏酸与富里酸总量、胡敏酸以及富里酸含量差异显著,稻壳/木屑垫料不同配比同一取样时期垫料内胡敏酸与富里酸总量、胡敏酸以及富里酸含量差异不显著.不同垫料间胡敏酸E4/E6差异显著,表现为发酵猪粪>果树枝>菌糠>中药渣(初始期除外),稻壳/木屑配比为60/40时胡敏酸E4/E6值较低. |

| Humus fractions and their content are indexes for compost quality. The present study investigated the dynamic changes of humus fractions including humic acid(HA) and fulvic acid(FA) in different pig bio-bed litters during one whole period of pig-raising. The litter materials included two groups-fruit tree branches, mushroom cultivation waste, traditional Chinese medicine residues and digested pig manure in one group and different ratios of sawdust and rice husk in another group. The experiment was conducted in a pig bio-bed farm in Luhe animal science base, Jiangsu Academy of Agricultural Sciences, from July 2011 to October 2011. Results showed that total humic acid amount(sum of HA and FA) was highest in the original traditional Chinese medicine residues, while HA content and E4/E6 ratio were highest in the original mushroom cultivation waste. The change patterns of total humic acid amount and FA content in bio-bed litters were different from those in ordinal composts. The amount of total humic acids of bio-bed litters increased in the first three months and then decreased in the fourth month, while FA content of bio-bed litters increased in the first two months and then decreased, with an exception of traditional Chinese medicine residue litter. The HA content increased in the bio-bed litters, except mushroom waste, but E4/E6 ratio decreased in all bio-bed litters during four month of pig-raising. However, total humic acid amount, HA and FA content, and E4/E6 ratios in the bio-bed litters were lower after three pig-raising periods(two years) than after one period(four months). At the same sampling time, total humic acid amount, HA and FA content differed significantly(P<0.05) among traditional Chinese medicine residue, mushroom cultivation waste, fruit tree branches and digested pig manure, but these indexes did not differ significantly(P<0.05) in different ratios of sawdust and rice husk. The E4 /E6 ratios showed significant differences(P<0.05) between different litters, with descending order of digested pig manure >fruit tree branches > mushroom cultivation waste>traditional Chinese medicine residue(except the initial bio-bed litters). The lowest E4 /E6 ratio was found in the 60/40 sawdust/rice husk mixture. |
