将鄂东南第四纪红色粘土发育的棕红壤分别与 5种植物物料混合 ,进行腐解试验。研究表明 :各种作物的秸秆在初期分解量较大 ,物料混合土样的含硼量在分解初期迅速下降 ,最后接近土壤有机硼含量 ;硼的释放较有机物矿化要快 ,其半释放期在 30～ 43d ,99%的有机硼释放时间要 2 74d ,而 99%的有机物分解在 5 74d
The red brown soil developed in Quaternary red clay in southeastern Hubei was mixed with five kinds of plant materials respectively for decomposing. The results showed that: the amount of straw decomposition in various crops was large at the initial stage, and the content of boron in the mixed soil samples rapidly decreased at the initial stage of decomposition and finally approached the content of soil organic boron; the release of boron was faster than the mineralization of organic matter, In 30 ~ 43d, 99% of the organic boron release time to 2 74d, 99% of the organic decomposition in 5 74d
