| 1 | 棉花主茎叶与根系硝酸还原酶活性分布对播期和密度的响应显示文摘【目的】本研究旨在探讨大田轻简化栽培条件下棉花氮代谢随播期和密度的变化规律。【方法】选用华棉3109(G.hirsutum L.)于2014年在华中农业大学试验农场,采用裂区设计:播期为主区(S1,5月30日;S2,6月14日),密度为副区(D1,7.5株·m-2;D2,9.0株·m-2;D3,10.5株·m-2),研究了硝酸还原酶(Nitrate reductase,NR)活性在主茎叶位和根系的分布特点。【结果】1)不同播期和密度对叶片和根系NR活性平均值有显著影响。推迟播期对现蕾期棉花叶片与根系平均NR活性无显著影响,增加密度可降低叶片平均NR活性,但对根系平均NR活性无显著影响;推迟播期,显著降低初花期和盛花期棉花叶片NR活性平均值,但晚播对根系NR活性平均值的影响由侧根NR决定,增加密度,叶片和根系平均NR活性呈先升高后降低变化趋势,表明见花施肥后,晚播抑制了棉花地上部叶片氮代谢强度,而增强了地下部根系氮代谢强度;适度增加密度可显著增强棉花地上部叶片和地下部根系氮代谢强度。2)现蕾期叶片NR活性平均值>初花期>盛花期,根系NR活性平均值大体呈先升高后降低变化趋势。3)主茎叶位NR活性在3个时期均由上而下显著降低,以第1叶至第3叶波动较大,第4叶以下叶片间无显著差异,表明叶片NR活性与叶龄有关,幼叶氮代谢强度高于成熟叶片,成熟叶片之间氮代谢强度保持相对稳定。【结论】长江流域棉区(主要指湖北植棉区)棉花播种不应晚于6月14日,种植密度以9.0株·m-2最佳。 | 王雷山 Khan Aziz 宋兴虎 黄颖 袁源 杨国正 | 2017 | 棉花学报2017，29，1： | 4 |
| 2 | 棉花产量因主茎不同叶位叶绿素含量变化对播期和密度的响应显示文摘叶绿素含量是田间诊断氮素营养供应状况指标之一,与氮代谢密切相关。【目的】为探讨播期和密度对迟直播棉花主茎不同叶位氮代谢与产量的影响。【方法】采用裂区试验设计,以播期(月-日)(S1,05-30;S2,06-14)为主区,密度(株·m-2)为副区(D1,7.5;D2,9.0;D3,10.5),在大田试验条件下研究了不同生育时期棉花主茎不同叶位叶绿素含量的动态变化。【结果】1)棉花叶绿素a、b、(a+b)含量盛花期>初花期>现蕾期,且随叶位由上而下先升高(倒3~5叶最高)后降低,随密度增加而降低,播期间(现蕾期、初花期、盛花期)S2显著高于S1(现蕾期叶绿素b无显著差异),播期、密度均不改变这些指标在叶位间的变化趋势,播期与密度交互作用存在差异(应作相应的统计分析);2)棉花叶绿素a/b现蕾期>初花期(盛花期),不同叶位间现蕾期随叶位由上而下先升高(倒3~4叶最高)后降低,但初花期和盛花期变化平缓,播期、密度不影响叶位间的变化趋势;3)通过逐步回归分析法,得到单叶叶绿素含量(叶绿素(a+b)、叶绿素a、叶绿素b、叶绿素a/b)能够显著代表整株平均水平的叶位,即为棉花叶绿素含量典型叶,现蕾期为倒5叶,初花期为倒4叶,而盛花期随叶绿素指标不同而异。【结论】S1D2产量最高,叶绿素含量、a/b值比较合理。 | 王雷山 Khan Aziz 黄颖 宋兴虎 Souliyanonh Biangkham 袁源 杨国正 | 2017 | 棉花学报2017，29，2： | 4 |
| 3 | 播期和密度对棉花叶柄和根系硝态氮含量的影响显示文摘为探讨大田棉花氮代谢随播期和密度的变化规律,选用华棉3109(G.hirsutum L.)于2014年在华中农业大学试验农场,采用裂区设计:播期(月-日)(S1,05-30;S2,06-14)为主区,密度(株·m-2)(D1,7.5;D2,9.0;D3,10.5)为副区,研究了硝态氮含量在主茎叶柄和根系的分布特点。结果表明:1)随生育进程推进,叶柄和根系硝态氮含量先升高后降低,初花期最高。2)主茎叶柄硝态氮含量随叶位变化,蕾期、初花期由上而下逐渐降低,第1叶最高;盛花期逐渐增高,第1叶和第4叶最高;不同生育时期棉花叶柄硝态氮含量在叶位间的下降幅度随播期推迟而降低,随密度增加先升高后降低。3)播期和密度对不同生育时期棉花叶柄和根系硝态氮平均含量的交互作用均显著,但播期和密度主效应影响不同:见花施肥前,随推迟播期,棉花叶柄硝态氮平均含量显著降低了42.9%,根系硝态氮平均含量显著升高了12.1%,增加密度对叶柄和根系硝态氮平均含量无显著影响。见花施肥后,随播期的推迟,叶柄硝态氮平均含量无显著性变化,初花期平均为5.05 mg·g-1,盛花期平均为2.62 mg·g-1;而根系硝态氮平均含量,初花期S1>S2,盛花期S1 | 王雷山 Khan Aziz 袁源 武莹莹 Adnan Noor Shah Shahbaz Tung 杨国正 | 2016 | 棉花学报2016，28，6： | 3 |

| 5 | Characterization of vanadyl phthalocyanine based surface-type capacitive humidity sensors显示文摘This study presents the fabrication and characterization of novel surface-type capacitive humidity sensors using vanadyl phthalocyanine(VOPc) as the active material.The devices,which comprise three different thicknesses, have been fabricated using the thermal evaporation technique.A thin film of VOPc is deposited on thoroughly cleaned glass substrates with pre-patterned Ag electrodes.The capacitive effect of the samples under humidity has been investigated. Comparison of the samples with different thicknesses shows that the thinnest device seems more sensitive towards humidity.The humidity dependent capacitance properties of the sensor make it beneficial for use in commercial hygrometers. | Fakhra Aziz M.H.Sayyad Khassan S.Karimov M.Saleem Zubair Ahmad S.Mahmood Khan | 2010 | Journal of Semiconductors2010，31，11： | 2 |

| 12 | Structural,electrical,dielectric and magnetic properties of Mn-Nd substituted CoFeO_3 nano sized multiferroics显示文摘A series of Mn x Co_(1-x) Fe_(1-y) Nd_yO_3(where x=0.0–1.0 & y=0.0–0.1) multiferroic nanocrystals was synthesized via sol-gel auto-combustion technique. The structure was confirmed by X-ray diffraction(XRD)while morphology was investigated by scanning electron microscopy(SEM). The electrical resistivity was observed to increase from 2.14 * 10~7 to 8.77 * 10~9 Ω-cm and activation energy was found to increase from 0.64 to 0.75 e V, while the drift mobility decreased from 4.75 * 10^(-13) to 1.27 * 10^(-15)cm^2V^(-1)S^(-1) by the substitution of Mn and Nd contents. The dielectric constant, dielectric loss and dielectric loss factor decrease with frequency and Mn-Nd contents. The saturation magnetization was increased from 34 to 70 emu g^(-1) while the coercivity decreased from 705 to 262 Oe with the increase of substituents.The increase in electrical resistivity and saturation magnetization while decrease in dielectric parameters and coercivity make these nanomaterials suitable for applications in microwave devices and longitudinal magnetic recording media. | Abdul Aziz E.Ahmed Muhammad Naeem Ashiq Muhammad Azhar Khan Nazia Karamat Irshad Ali | 2016 | Progress in Natural Science:Materials International2016，26，4： | 1 |

| 15 | Impact of Tillage and Herbicides on Weed Density, Yield and Quality of Cotton in Wheat Based Cropping System显示文摘Conservation tillage may improve yield of cotton in addition to improvement in soil quality if practiced for longer period. However, the practice may not be productive in short-term particularly when severe weeds are infesting the crops such as Cynodon dactylon, Conyza canadensis, Tribulus terrestris, and Cyperus rotundus, etc. Recent studies indicate that conventional tillage (CT) is more productive than zero tillage (ZT)/reduced tillage (RT). Performance of cotton under three tillage systems, viz., ZT, RT and CT; and five herbicides, i.e., haloxyfop-R-methyl 10.8 EC (108 g a.i. ha^(-1)), lactofen 24 EC (168 g a.i. ha^(-1)), haloxyfop 10.8 EC + lactofen 24 EC, hand weeding, and weedy check were evaluated during 2010-2011 at Gomal University, D.I.Khan, Pakistan, to explore the best management option for effective weed control, enhanced yield and quality of cotton grown after wheat. The results revealed that hand weeding and Haloxyfop as post emergence alone or in combination with Lactofen reduced weed density to the minimum irrespective of the tillage systems. Excessive rainfall and cooler temperature limited cotton growth and yield in 2010. The adverse weather conditions had more adverse effect on boll weight under ZT and RT than CT. Haloxyfop + lactofen produced higher seed cotton yield in RT than ZT, however, it could not exceed CT. Broad-spectrum herbicides×CT produced the highest number of bolls/plant, boll weight and seed cotton yield. Fiber quality and net returns were also the highest in broad-spectrum herbicides×CT. In conclusion, broad-spectrum herbicides under CT were more productive in wheat based cropping system on silty clay soil of D.I.Khan. | Khalid Usman Niamatullah Khan Muhammad Umar Khan Aziz ur Rehman Said Ghulam | 2013 | Journal of Integrative Agriculture2013，12，9： | 1 |
