long-Term Application of Organic Manure and Mineral Fertilizer on N_2O and CO_2 Emissions in a Red Soil from Cultivated Maize-Wheat Rotation in China

引用

Agricul.ural Sciences in China 2011年第11期10卷 1748-1757页

作者： ZHAI li-mei l.u Hong-bin ZHANG Ji-zong HuANG Jing WANG Bo-ren Key laboratory of Nonpoint Pol.ution Control Ministry of Agriculture~Institute of Agricultural Resources and Regional Planning ChineseAcademy of Agricultural Sciences Beijing 100081 P.R.China

A long-term field experiment was established to determine the influence of mineral fertilizer and organic manure on soil fertility. A tract of red soil （Ferralic Cambisol） in Qiyang Red Soil Experimental Station （Qiyang County, Hunan Province, China） was fertilized beginning in 1990 and N20 and CO2 were examined during the maize and wheat growth season of 2007-2008. The study involved five treatments： organic manure （NPKM）, fertilizer NPK （NPK）, fertilizer NP （NP）, fertilizer NK （NK）, and control （CK）. Manured soils had higher crop biomass, organic C, and pH than soils receiving the various mineralized fertilizers indicating that long-term application of manures could efficiently prevent red soil acidification and increase crop productivity. The application of manures and fertilizers at a rate of 300 kg N ha-1 yr-1 obviously increased NzO and CO2 emissions from 0.58 kg N20-N ha-~ yr-~ and 10565 kg C ha-~ yr-~ in the CK treatment soil to 3.0l kg N20-N ha-~ yr-~ and 28 663 kg C ha-~ yr-I in the NPKM treatment. There were also obvious different effects on N20 and CO2 emissions between applying fertilizer and manure. More N20 and CO2 released during the 184-d maize growing season than the 125- d wheat growth season in the manure fertilized soils but not in mineral fertilizer treatments. N20 emission was significantly affected by soil moisture only during the wheat growing season, and CO2 emission was affected by soil temperature only in CK and NP treatment during the wheat and maize growing season. In sum, this study indicates the application of organic manure may be a preferred strategy for maintaining red emissions than treatments only with mineral fertilizer. soil productivity, but may result in greater N20 and CO2

针对旁瓣对消中出现的目标效应问题,将基于斜投影算子的极化滤波技术引入到旁瓣对消系统,提出了一种消除旁瓣对消系统中目标效应的新方法.实时估计出强干扰的极化参数,计算获得斜投影算子并作用于辅助通道回波,利用斜投影算子的优良性能便可完全消除辅助通道的目标信号,同时完整保留辅助通道的干扰,再利用旁瓣对消技术可大幅度抑制主通道的干扰而保持信号无损失.相比于传统的极化滤波方法,该方法仅需获取强干扰的极化参数,便可完全抑制辅助通道中微弱的目标信号,大幅度提高旁瓣对消比,解决旁瓣对消系统中的目标效应问题.理论分析和仿真结果验证了这种方法的有效性.

Restricted nutrient intake does not alter serum-mediated measures of implant response in cell cul.ure

Journal of Animal Science and Biotechnology 2014年第1期5卷 80-87页

Background： During nutritional stress, reduced intake may reduce the efficacy of anabolic implants. This study was conducted to evaluate basic cel.ular responses to a growth promotant implant at two intake levels. Methods： Sixteen crossbred steers （293 ± 19.3 kg） were used to evaluate the impact of anabolic implants in either an adequate or a restricted nutritional state. Steers were trained to individual Calan gates, and then randomly assigned to 1 of 4 treatments in a 2 × 2 factorial arrangement. Treatments consisted off presence or absence of an anabolic growth implant （Revalor-XS, 200 mg TBA and 40 mg estradiol; IMPlANT or CONTROl） and a moderate energy, pelleted, starting cattle diet fed at either 2.0 × or 1.0 × maintenance energy （NEM） requirements （HIGH or lOW）. Serum （d O, 14, and 28） was used for application to bovine muscle satellite cells. After treatment with the serum （20% of total media） from the trial cattle, the satellite cells were incubated for 72 h. Protein abundance of myosin heavy chain （MHC）, phosphorylated extracel.ular signal-related kinase （phospho-ERK）, and phosphorylated mammalian target of rapamycin （phospho-mTOR） were analyzed to determine the effects of implant, intake, and their interaction （applied via the serum）. Results： Intake had no effect on MHC （P = 0.85） but IMPlANT increased （P 〈 0.01） MHC abundance vs. CONTROl. Implant status, intake status, and the interaction had no effect on the abundance of phospho-ERK （P〉0.23）. Implanting increased phospho-mTOR （P 〈 0.01） but there was no effect （P 〉 0.51） of intake or intake x implant. Conclusions： The nearly complete lack of interaction between implant and nutritional status indicates that the signaling molecules measured herein respond to implants and nutritional status independently. Furthermore, results suggest that the muscle hypertrophic effects of anabolic implants may not be mediated by circulating IGF-1.

采集我国15个省份理化性质差异很大的耕作土壤,利用温室试验,以小白菜为研究对象,通过外源添加铬(Cr),研究Cr从土壤向植物的运移,探索影响Cr生物有效性的主要土壤因素,并建立预测模型。结果表明,土壤总Cr含量、pH值和有机碳(OC)含量对小白菜吸收Cr有显著影响。小白菜Cr含量与土壤Cr含量呈正相关,而与土壤pH值、OC含量呈负相关。相比于土壤总Cr含量的单因素回归分析,将土壤总Cr含量、pH值和有机碳(OC)含量纳入逐步多元线性回归(SMlR)后评价Cr生物有效性时,相关性更高,决定系数由0.861提高到0.927。Cr在酸性土壤中生物富集系数(BCF)较碱性土壤中更大。利用合并CK、Cr1、Cr2处理3个处理的数据(n=45)得到Freundlich预测方程(R2=0.927,RMSE为0.12),较单独使用CK处理数据(R2=0.572,RMSE为0.25,n=15)和使用Cr1和Cr2处理结合的数据(R2=0.745,RMSE为0.17,n=30)得出的方程,能更准确地评估Cr在土壤中生物有效性,试验结果可用于预测Cr从土壤到小白菜的转移。

Powdery mildew, caused by the biotrophic fungus Blumeria graminis f. sp. tritici(Bgt), is a prevalent disease in common wheat(Triticum aestivum l.) and causes serious yield losses worldwide. We used a map-based approach to clone the major broad-spectrum powdery mildew resistance gene Pm CH1357 from wheat breeding line CH1357. Pm CH1357 was mapped to a 526 kb region containing only Traes CS5 D01 G044600. The Traes CS5 D01 G044600 sequence of the susceptibility allele in Taichung 29(TC29) was identical to that in Chinese Spring, whereas the sequence of the resistance allele in CH1357 was identical to Pm2a previously cloned from the germplasm ulka/*8Cc. The susceptibility allele in TC29 contained a 7 bp deletion in exon 1, resulting in loss of 856 of the 1277 amino acids in the predicted nucleotide-binding domain l.ucine-rich repeat containing Pm2a *** CH1357/Pm2a sequence was also isolated from the Chinese wheat landraces and cultivars that were previously reported to possess the resistance gene Pm2b, Pm2c,PmlX66, or PmND399. The Pm CH1357/Pm2a resistance allele was present in 10 of 495 accessions in core germplasm and contemporary cultivars from China and the uSA. A newly developed diagnostic marker for the 7 bp In Del in the resistance gene can be used to eliminate the susceptibility allele in wheat breeding programs.

为了解决装载机发动机与液力变矩器匹配性能评定指标较多,多项评价指标权重难以确定的问题,该文提出了基于性能评价网状图的发动机与液力变矩器匹配优化方法。装载机发动机与液力变矩器匹配性能评定指标有额定工况接近度、起动能度、经济区宽容度、功率输出系数、燃油消耗率系数等5项,分别定义和计算5项匹配性能指标,根据计算值的大小构建发动机与液力变矩器匹配性能网状评价图,以网状评价图面积最小为优化目标,构建目标函数,优化液力变矩器有效直径。原液力变矩器有效直径等于0.360 m;优化后的装载机液力变矩器有效直径等于0.350 m。优化后发动机与液力变矩器匹配性能提高了5.7%。基于性能网状图的优化方法提高了发动机与液力变矩器匹配性能。
