1 Reduction Effects onSPADValues of Wheat Leaves and Its Correlation with Yield under Waterlogging StressHUANGQin-you,TIANWen-taoCollegeofAgronomy,YangtzeUniversity，Jingzhou，Hubei434025，ChinaWANGXiao-lingCollegeofAgronomy,YangtzeUniversity;HubeiCollaborativeInnovationCenterforGrainIndustry(YangtzeUniversity)，Jingzhou，Hubei434025，ChinaAbstract: The reduction effects onSPADvalues of wheat(Triticumaeestivum) leaves and its correlation with yield under waterlogging stress were carried out.The field experiment was conducted at flowering stage of wheat.One hundred and sixty four cultivars or advanced lines were used as experiment materials,which were collected from different wheat-planting areas,and an artificial simulation waterlogging treatment was designed with normal water condition as control in the trial.SPADvalues were measured respectively before waterlogging treatment and after the treatment in the plots of treatment and control.Yield was measured at maturity stage.The waterlogging indexes both ofSPADvalues of different leaves and yield were calculated for different wheat cultivars and compared.The results showed thatSPADvalues of wheat were significantly reduced at flowering stage under waterlogging condition and theSPADvalues showed significant difference for leaves in different stem positions.SPADvalues of the first inverse leaf showed no significant difference butSPADvalues of the second inverse leaf to the inverse fourth leaf were in the opposite way under waterlogging treatment of 12 days.SPADvalues showed a natural reduction with no significant difference at the 12 days of waterlogging treatment for the second inverse leaf but with the opposite results for the third and fourth inverse leaves in the control plots.SPADvalue of the second inverse leaf could be utilized to measure the injury degree of waterlogging when treatment period was more than 12 days and the third inverse leaf was the optimum when treatment period was less than 12 days.TheSPADvalue of the third and fourth inverse leaves were the first choice when waterlogging tolerance of different varieties or advanced lines were compared for its higher correlation with yield under waterlogging stress.

47 Study on Fast Method for Determination of Seed Husk Content in BarleyGONGQiang,WANGGuo-rongLIBo,XUYan-haoHubeiCollaborativeInnovationCenterforGrainIndustry(YangtzeUniversity),Jingzhou,Hubei434025,China；CollegeofAgronomy,YangtzeUniversity,Jingzhou,Hubei434025,ChinaAbstract: Aqueous ammonia method(SAA) and sulphuric acid method for soaking were two main methods for determination of barley seed husk content.However,the two methods were not suitable for measure large numbers of samples.Cellulose was the major chemical component of barley husk.The new cellulose dissolution system was used to develop a rapid,stable and high-throughput method for barley husk content determination.The results confirmed that alkaline sodium hypochlorite was more effective compared to sodium hydroxide treatment，sodium hypochlorite solution and sodium hydrate/urea aqueous solution for barley husk content determination.The concentrations of NaOH,NaClO,and the treatment time were adjusted to produce a stable and fast alkaline sodium hypochlorite method.The results showed that 4% NaOH combined with 20% NaClO and treated by 2 min boiling was the most reliable combination of alkaline sodium hypochlorite method.The accuracy and repeatability of alkaline sodium hypochlorite method were compared with the SAA and sulphuric acid method,which further confirms that the alkaline sodium hypochlorite method was the most suitable method for determining large number of barley husk contents. Key words:barley;husk content;alkaline sodium hypochlorite;cellulose dissolution system

62 Measure Analysis for Carbon Footprint of the Farmland Ecosystem in Tianmen CitySHENTi-zhongAgriculturalEnvironmentalProtectionStationofTianmen,HubeiProvince，Tianmen，Hubei431700,ChinaAbstract: The carbon absorption,carbon emissions and carbon footprint of farmland ecosystem were quantitatively analyzed by using the related statistical data of arable land,crop yields,investment and so on in Tianmen City from the year 2003 to 2012.The results showed that the crop’s carbon uptake,carbon absorption intensity present a tendency of increasing year by year in the 10 years with the progression of years,and they increased from 787.90×103t C,7.24t C/hm2in 2003 to 1144.01×103t C and 10.35t C/hm2in 2012.The carbon emissions and carbon intensity in the farmland were in change trend of increase at first and lowered later and increase again,and the change range was (89.04～106.12)×103t C/a and 0.82～0.98t C/(hm2·a),and the fertilizer was the main source of carbon emissions.The ecosystem carbon sequestration of the farmland and its carbon footprint decreased year by year with the progression of years,and it was reduced from 48.81×103hm2in 2003 to 37.70×103hm2in 2012,which accounts for 34.12%～ 44.85% of the arable land in the same period,and it was significantly less than the regional ecological carrying capacity.
