| 1 | Soil physical quality as influenced by long-term fertilizer management under an intensive cropping system显示文摘In China’s major rice(Oryza sativa L.)production regions,the traditional fertilization modes are challenged by the continued decrease in manure and increase in mineral fertilizer.However,limited information exists on the influences of long-term fertilizer management on soil organic carbon(SOC)and soil physical properties under the intensive rice production system in southern China.The objective of this study was to characterize the changes of soil physical properties as related to mineral fertilizer,crop residues,and manure application based on a long-term field experiment.The experiment,initiated in 1986,has five treatments:unfertilized,mineral fertilizer alone,rice residues plus mineral fertilizer,low manure rate plus mineral fertilizer,and high manure rate plus mineral fertilizer.The cropping system consists of barley(Hordaum vulgare L.),early rice,and late rice,three crops in a year.In May 2006,after barley harvest,soil samples were collected from the 0~10 cm and 10~20 cm layers to determine SOC concentration,aggregate size distribution,bulk density(rb),saturated hydraulic conductivity(Ks),and soil water characteristic curves(SWCC).The results indicated that manure significantly reducedrb,increased SOC concentration,soil aggregation,Ks,transmission and storage porosity,as well as water retention capacity.Combined application of crop residue and mineral fertilizer also improved soil physical properties,but the improvement by mineral fertilizer alone was limited.Correlation analysis demonstrated that S,the slope of the SWCC at its inflection point,was closely associated with the selected physical parameters,suggesting S was an effective parameter for soil physical quality evaluation.Nevertheless,in applying the S-theory,a unified approach to define the residual water content should be considered. | Du Zhangliu Liu Shufu Xiao Xiaoping Yang Guangli Ren Tusheng | 2009 | International Journal of Agricultural and Biological Engineering2009，2，1： | 4 |
| 2 | Effects of Manufactured-sand on Dry Shrinkage and Crccp of High-strength Concrete显示文摘自然的沙,制造沙(MS ) 和在可使用性,压缩强度,有弹性的模量,弄干的收缩和高张力水泥(HSC ) 的 creep 性质上的制造沙的石头灰尘(SD ) 的影响被测试并且比较。结果证明合理内容(7%10.5%) 不在 MS 的 SD 败坏 MS-HSC 的可使用性。它能甚至改进可使用性。而且,逐渐地,与增加, SD 满足的压缩强度增加,和有低 SD 的 MSHSC 满足(比 7% 小) 当 SD 内容高时,有接近自然的沙 HSC,而是有弹性的模量还原剂的有弹性的模量。弄干 MS-HSC 的收缩性能上的 SD 内容的影响是仔细与水和年龄有关。在 7 d 变老的前者的 MS-HSC 的收缩率比在迟了的年龄的收缩率的自然的沙 HSC,而是差别的高没被标记。当苍蝇灰被增加,同时,收缩率减少;有 7% SD 的 MS-HSC 的特定的 creep 和 creep 系数自然的沙 HSC 接近那些。 | ZHOU Mingkai WANG Jiliang ZHU Lide HE Tusheng | 2008 | Journal of Wuhan University of Technology(Materials Science)2008，23，2： | 3 |
