Curing Characteristics and Suitable Harvest Maturity of Fresh Flue-cured Tobacco Leaves in Ankang Tobacco Growing Areas

CuItivars K326, Yunyan 87 and Guiyan 4 were used to investigate the curing characteristics and suitabIe harvest maturity of fresh fIue-cured tobacco Ieaves in Ankang tobacco growing areas. ResuIts indicated that the water Ioss of K326 was sIow,and the Ieaves were resistant to curing and reIative easiIy to cure. The water Ioss of Yunyan 87 and Guiyan 4 were quick, and the Ieaves with normal resistance to curing were reIative difficuIt to cure. For Guiyan 4, the shrinkage of CM1 maturity was the Iargest. For K326 and Yunyan 87, the shrinkages of CM2 maturity were the Iargest whiIe the shrinkage of CM1 maturity was the Iowest, but the difference did not reach statistical significance. The proportion of top-middIe-grade tobacco Ieaves and average price for K326 were the highest with XM2, CM2 and BM2 maturity, and for Yunyan 87 were XM1, CM3 and BM2 maturity. For K326, Ieaves with XM2, CM2 and BM2 maturity showed the balanced chemical components and the best smoking quality.

Factors Controlling Precipitation of Barite and Witherite and Genesis of the Ankang-Xunyang Barium Deposits,Shaanxi,China

The barium deposits in Ankang and Xunyang counties,Shaanxi Province,China,occur in the northernmost part of the world-class barium metallogenic belt in south Qinling.The deposits are hosted by the Lower Silurian carbonaceous siliceous rocks,with a unique combination of barite and witherite.The homogenization temperatures of fluid inclusions in the barite are mainly concentrated between 135 and 155 ℃,whereas those from the witherite have two peaks of 165-175 ℃,and 215-225℃,respectively.Laser Raman analysis of fluid inclusions indicates that the vapor phase of fluid inclusions in barite is dominated by H_2O,although some contains N_2,H_2S,and CH_4.The compositions of the vapor and liquid phases of fluid inclusions in witherite can be divided into two end-members,one dominated by H_2O without other volatiles,and the other containing CH_4,C_2H_6,C_3H_8,C_2H_4,and C_6H_6 in addition to H_2O.CO_2,H_2S,and some CH_4 are interpreted as products of chemical reactions during mineralization.Organic gases（CH_4,C_2H_6,C_3H_8,C_2H_4,and C_6H_6） in the fluids were critical in the formation of barium sulfate versus carbonate.The δ^（34）S values of barite range from 38.26‰ to54.23‰（CDT）,the δ^（34）S values of sulfides coexisting with barium minerals vary from 22.44‰ to25.11‰（CDT）,and those in the wall rock from 11.60‰ to 19.06‰（CDT）.We propose that the SO_4^（2-）generally experienced bacterial sulfate reduction in seawater before mineralization,and some SO_4^（2-）also experienced thermochemical sulfate reduction in hydrothermal system during mineralization.The δ^（13）C values of witherite range from-27.30‰ to-11.80‰（PDB）,suggesting that carbon was sourced from organic substances（like CH_4,C_2H_4,and C_2H_6）.The formation of witherite was possibly associated with thermochemical sulfate reduction,which caused the consumption of the organic gases and SO_4^（2-） in the hydrothermal solutions,consequently inhibiting barite formation.The important conditions for forming witherite include high fluid temperatures,high Ba^（2＋） concentrations,CO_2 in the fluids,low HS^- concentrations,and the subsequent rapid diffusion of H_2S during thermochemical sulfate reduction of the fluids.

Analysis on the Characteristics of Rainstorm in Hanbin District of Ankang City during 1961-2003

[Objective] The research aimed to analyze the rainstorm characteristics in Hanbin District of Ankang City in 43 years. [Method] By using the daily and hourly precipitation data in Hanbin District of Ankang City during 1961-2003, the occurrence rule and variation characteristics of rainstorm weather in 43 years in the zone were analyzed. [Result] The distribution of rainstorm days in Hanbin District of Ankang City had the obvious season characteristic. The earliest rainstorm days occurred in May and started to increase in June. It frequently happened in July, August and gradually decreased in September. The latest rainstorm finished in the middle ten-day of October. The storm rainfall and days in Hanbin District of Ankang City during 1961-2003 both presented the obvious linear increase trend. From the 1970s to the end of 1980s, it was the period when the storm rainfall was more. The rainstorm days during the 1960s-early 1970s and early 1990s were fewer. The rainstorm days were more from the metaphase of 1970s to late 1980s and after the metaphase of 1990s. The time distribution characteristic of hourly precipitation in the rainstorm days was obvious and based mainly on the single peak type. The time mainly concentrated in the daytime, and the short-time strong precipitation was more. [Conclusion] The research provided the reference basis for accurately forecasting the rainstorm occurrence, disaster prevention and reduction work.

Comprehensive Analysis and Evaluation of the Climate in Ankang in 2012

[Objective] The study aimed to analyze and assess the climate in Ankang in 2012. [Method] Based on the real-time data of temperature, precipitation and sunshine hours from ten meteorological observations in Ankang City from 1961 to 2012, climatic characteristics of Ankang City in 2012 were analyzed firstly, and then the effects of main climatic events （drought, high temperature, rainstorm and flood, low temperature, hail and gale） on agriculture, energy, traffic and tourism were discussed. [Result] In 2012, annual average temperature in Ankang City was 14.6 ℃, 0.4 ℃ lower than the normal average over the past pears; annual average precipitation was 823.5 ram, 9.7% lower than the normal average; an- nual average sunshine hours were 1 459.6 h, 213.9 h less than the normal average. Most areas of Ankang City had suffered many meteorological disasters successively in 2012, such as low temperature, drought, windstorm, high temperature, thunder and lightning, gale, fog and haze. Drought, high temperature, rainstorm, hail, gale and other natural disasters had affected agriculture, forestry, traffic and tourism and brought great economic toss. [Conclusion] The research could provide scientific references for agricultural production and people＇s life in future.

基于DEA模型的安康市农业投入产出效率评价

为了解安康市现代农业发展效率状况,选取2009—2020年安康市污染治理投资总额、农业固定资产投资额、耕地面积和乡村劳动力资源总数4个农业投入指标,以及农业总产值和农业人均生产值2个农业产出指标,采用数据包络分析(data envelopment analysis,DEA)模型中的BCC模型进行效率分析。结果表明,安康市农业投入产出效率只有2020年的DEA模型是有效的,但从2009年开始,综合效率总体呈现上升趋势;从投入冗余率与产出不足率可以看出,安康市农业总产值基本不存在产出不足的现象,除2020年外,其余各年份在污染治理投资总额、农业固定资产投资额、耕地面积和乡村劳动力资源总数的投入在不同程度都存在冗余,投入结构不合理造成DEA模型无效。

1960—2019年安康市气候季节及不同等级积温变化特征

揭示气候变暖背景下安康市气候季节、积温等气温指标的变化特征,为区域人类活动适应气候变化、调整农业生产提供科学依据。基于安康站1960—2019年逐日平均气温数据,利用5 d滑动平均、线性拟合等方法,探讨安康市气候季节和不同等级积温(≥5℃、≥10℃、≥15℃、≥20℃)的初日、持续日数和气(积)温的时序变化规律。结果表明:(1)1960—2019年安康年均气温以0.012℃·a^(-1)的速率显著上升(P<0.01),并在1997年发生升温突变;气候季节和不同等级积温的初日、持续日数等气温指标的年代际变化特征各异。(2)1960—2019年安康气候季节平均气温均呈不显著微弱上升趋势,其中以春季(0.012℃·a^(-1))增温幅度最大;春季的初日(持续日数)显著提前(增加),夏、秋和冬季一致表现为初日不显著推迟、持续日数不断缩短的趋势,其中推迟(缩短)程度以夏(秋)季最为突出。(4)1960—2019年安康≥5℃、≥10℃、≥15℃和≥20℃积温一致表现出初(终)日提前(推迟)、持续日数和活动积温增加的趋势。其中以≥15℃积温的初日、持续日数和活动积温提前(增加)最多,终日以≥10℃积温推迟最为明显。因此,安康市气候季节和积温对全球气候变暖现象响应明显。

安康湘语“咖”[kA^(0)]的语义及用法考察

在陕南安康湘语中,“咖”的使用频率非常高,既可以作动结式第二成分,有着较为实在的词汇意义,也可以作动态助词,表示动作的完成,意义完全虚化。与迁出地湘语“咖”相比,安康湘语“咖”的使用受限较多,且只能与“哩”组合使用,这说明移民方言不仅受周边方言的影响,其内部之间也会相互影响。

南秦岭安康成矿带金矿地质特征与成矿条件研究

安康金成矿远景区位处南秦岭安康成矿带,区内赋矿层位为志留系下统斑鸠关组、梅子垭组,受北西西-南东东向展布的叶坪河复式向斜构造控制,成矿类型属沉积改造型。岩石地球化学分析表明,Au元素在各地层的平均质量分数值范围为1.19×10^(-9)-~6.68×10^(-9),而经后期变质改造的各地层中(含矿层片岩类),Au元素的质量分数值升高,各变质地层Au元素的质量分数值范围为255×10^(-9)~711×10^(-9),平均值的范围为23.06×10^(-9)~26.52×10^(-9),具找矿前景,是勘查区内主要的找矿目标。认为地层岩性、构造特征、围岩蚀变、化探异常可作为该区域金矿床找矿的标志。

为探索适宜安康山地的烤烟大豆套种栽培模式,设置烤烟垄沟隔沟套种一行大豆模式(模式1,大豆密度3.13万株/hm^(2)、4.17万株/hm^(2)、6.25万株/hm^(2)、12.50万株/hm^(2))、烤烟垄沟隔沟套种两行大豆模式(模式2,大豆密度10.00万株/hm^(2))、烤烟垄面套种两行大豆模式(模式3,大豆密度20.00万株/hm^(2))等3种烟豆套种栽培模式,开展试验比较研究。结果表明:(1)模式1(3.13万株/hm^(2)、4.17万株/hm^(2))和模式2的大豆底荚高、有效分枝数等农艺性状和株荚数、株粒数、百粒重等单株经济性状极显著好于其他处理。(2)模式2和模式3的大豆单位面积纯收入无显著差异,极显著高于模式1。研究结论:模式2为安康市最优烟豆套种模式,大豆群体结构合理,个体生长势强、群体经济效益高,单位面积产量为1399.96 kg/hm^(2)、纯收益5033.11元/hm^(2),该模式有效化解了模式1大豆密度增加有限、产量低的问题,也避免了模式3大豆受烤烟遮阴影响大、受烤烟农事操作破坏大的弊端。

海拔高度对安康市烤烟品质的影响探究

【目的】研究安康烟区不同海拔高度与烤烟品种云烟99三种等级烟叶(B2F、C3F、X2F)烤烟质量以及风格特征的关联性。【方法】选择秦岭巴山一带海拔高度在355~1500 m之间的植烟区域,以云烟99作为研究对象,探究不同海拔高度对应烤烟在常规化学成分组成以及感官质量之间的影响作用。【结果】随着海拔高度的提升,不同等级烤烟常规化学成分和风格特性变化规律呈现差异性。其中B2F等级烤烟中烟碱、总氮和两糖比呈现下降趋势,总糖、还原糖、钾、氯、糖碱比、钾氯比呈现上升趋势,同时海拔高度越高,B2F等级烤烟香气质、香气量随之提升,而浓度、劲头、杂气和刺激性随之下降;C3F等级烤烟中烟碱、还原糖、氯、总氮和两糖比呈现下降趋势,总糖、钾、糖碱比、钾氯比呈现上升趋势,同时海拔高度越高,C3F等级烤烟香气质、香气量、杂气和刺激性随之提升,而浓度和劲头随之下降;X2F等级烤烟中烟碱、氯、总氮和两糖比呈现下降趋势,总糖、还原糖、钾、糖碱比、钾氯比呈现上升趋势,同时海拔高度越高,X2F等级烤烟香气质、香气量、浓度和劲头随之提升,而杂气和刺激性随之下降。【结论】随着海拔提升,不同等级烤烟总糖、钾、糖碱比、氮碱比皆保持上升趋势,同时烤烟的香气质和香气量也随着海拔提高而提高,其它因素存在差异性变化,因此认为适当提高植烟海拔高度,有利于提升烤烟的质量和烤烟中的清甜香型口味。
