| 1 | Estimating Leaf Chlorophyll Content Using Red Edge Parameters显示文摘Hyperspectral remote sensing makes it possible to non-destructively monitor leaf chlorophyll content(LCC).This study characterized the geometric patterns of the first derivative reflectance spectra in the red edge region of rapeseed(Brassica napus L.) and wheat(Triticum aestivum L.) crops.The ratio of the red edge area less than 718 nm to the entire red edge area was negatively correlated with LCC.This finding allowed the construction of a new red edge parameter,defined as red edge symmetry(RES).Compared to the commonly used red edge parameters(red edge position,red edge amplitude,and red edge area),RES was a better predictor of LCC.Furthermore,RES was easily calculated using the reflectance of red edge boundary wavebands at 675 and 755 nm(R675 and R755) and reflectance of red edge center wavelength at 718 nm(R718),with the equation RES =(R718-R675)/(R755-R675).In addition,RES was simulated effectively with wide wavebands from the airborne hyperspectral sensor AVIRIS and satellite hyperspectral sensor Hyperion.The close relationships between the simulated RES and LCC indicated a high feasibility of estimating LCC with simulated RES from AVIRIS and Hyperion data.This made RES readily applicable to common airborne and satellite hyperspectral data derived from AVIRIS and Hyperion sources,as well as ground-based spectral reflectance data. | JU Chang-Hua TIAN Yong-Chao YAO Xia CAO Wei-Xing ZHU Yan D.

| 2 | Effect of nitrogen fertilization on yield, N content, and nitrogen fixation of alfalfa and smooth bromegrass grown alone or in mixture in greenhouse pots显示文摘Planting grass and legume mixtures on improved grasslands has the potential advantage of realizing both higher yields and lower environmental pollution by optimizing the balance between applied N fertilizer and the natural process of legume biological nitrogen fixation. However, the optimal level of N fertilization for grass-legume mixtures, to obtain the highest yield, quality, and contribution of N2 fixation, varies with species. A greenhouse pot experiment was conducted to study the temporal dynamics of N2 fixation of alfalfa(Medicago sativa L.) grown alone and in mixture with smooth bromegrass(Bromus inermis Leyss.) in response to the addition of fertilizer N. Three levels of N(0, 75, and 150 kg ha–1) were examined using 15N-labeled urea to evaluate N2 fixation via the 15 N isotope dilution method. Treatments were designated N0(0.001 g per pot), N75(1.07 g per pot) and N150(2.14 g per pot). Alfalfa grown alone did not benefit from the addition of fertilizer N; dry matter was not significantly increased. In contrast, dry weight and N content of smooth bromegrass grown alone was increased significantly by N application. When grown as a mixture, smooth bromegrass biomass was increased significantly by N application, resulted in a decrease in alfalfa biomass. In addition, individual alfalfa plant dry weight(shoots+roots) was significantly lower in the mixture than when grown alone at all N levels. Smooth bromegrass shoot and root dry weight were significantly higher when grown with alfalfa than when grown alone, regardless of N application level. When grown alone, alfalfa's N2 fixation was reduced with N fertilization(R2=0.9376, P=0.0057). When grown in a mixture with smooth bromegrass, with 75 kg ha–1 of N fertilizer, the percentage of atmospheric N2 fixation contribution to total N in alfalfa(%Ndfa) had a maximum of 84.07 and 83.05% in the 2nd and 3rd harvests, respectively. Total 3-harvest %Ndfa was higher when alfalfa was grown in a mixture than when grown alone(shoots: |t|=3.39, P=0.0096; root: |t|=3.57, P=0.0073). We believe this was due to smooth bromegrass being better able to absorb available soil N(due to its fibrous root system), resulting inlower soil N availability and allowing alfalfa to develop an effective N2 fixing symbiosis prior to the 1st harvest. Once soil N levels were depleted, alfalfa was able to fix N2, resulting in the majority of its tissue N being derived from biological nitrogen fixation(BNF) in the 2nd and 3rd harvests. When grown in a mixture, with added N, alfalfa established an effective symbiosis earlier than when grown alone; in monoculture BNF did not contribute a significant portion of plant N in the N75 and N150 treatments, whereas in the mixture, BNF contributed 17.90 and 16.28% for these treatments respectively. Alfalfa has a higher BNF efficiency when grown in a mixture, initiating BNF earlier, and having higher N2 fixation due to less inhibition by soil-available N. For the greatest N-use-efficiency and sustainable production, grass-legume mixtures are recommended for improving grasslands, using a moderate amount of N fertilizer(75 kg N ha–1) to provide optimum benefits. | XIE Kai-yun LI Xiang-lin HE Feng ZHANG Ying-jun WAN Li-qiang David B Hannaway WANG Dong QIN Yan Gamal M A Fadul | 2015 | Journal of Integrative Agriculture2015，14，9： | 5 |

| 16 | 牧草生产潜力模拟模型及其应用显示文摘牧草生产潜力模拟模型(For-PASM)是模拟牧草的生长和产量形成的应用模型。For-PASM包括常年模拟和牧草品种参数调试两个系统。各系统包含生长周期、叶面积动态、收割期与收割次数及光合生产和产量等模块。牧草的生长发育是由气候因素决定的,依据积温来确定牧草生育期和收获期,禾本科以抽穗期为收获期,豆科牧草以初花期为收获期。模型的功能是模拟牧草的收获期、产量季节性动态以及年产量。用四川雅安市多花黑麦草(Lolium multiflorum Lam)和扁穗牛鞭草(Hemarthria compressa)生产数据进行检验。结果显示,For-PASM在模拟牧草收割期和牧草季节性的产量动态中,季节性干物质产量动态趋势与总产量均符合实际。 | 杨秀梅 张伟欣 高亮之 杨春华 张英俊 Hannaway B.David 张新全 | 2015 | 江苏农业学报2015，31，2： | 1 |
