Abstract:
本文利用2008~2012年乌江流域洪家渡水电站逐日入库流量、库水位和面雨量资料进行了相关分析和多元回归计算,针对电站500 m3/s和1000 m3/s两个关键入库流量,研究给出了该电站流域面雨量阈值指标。结果表明:洪家渡水电站库容水位涨落与入库流量密切相关,入库流量大于500 m3/s时,水位上涨明显;电站入库流量与前日流量相关性最好,相关系数R2达0.778,入库流量与前十日累积面雨量、前日面雨量相关系数R2分别为0.697和0.333;面雨量阈值表明,前日入库流量相对较小时,需要较大的面雨量才有可能形成500 m3/s或1000 m3/s的流量,而前日入库流量相对较大时,仅需要相对较小的面雨量就有可能形成500 m3/s或1000 m3/s的流量。
In this paper, the Hongjiadu Hydropower Station’s daily inflow, reservoir water level and area rainfall data are used to do the correlation analysis and multiple regression calculation, aiming at the two key inflows of 500 m3/s and 1000 m3/s of the power station. The study gives the rainfall threshold of the power station area. Results show that the reservoir water level of Hongjiadu Hy-dropower Station is closely related to reservoir inflow. When the inflow is more than 500 m3/s, water level rises significantly. Power station reservoir inflow best correlates with yesterday’s flow; the correlation coefficient R2 reaches 0.778. The correlation coefficient of reservoir inflow with cumulative area rainfall before ten days, and with yesterday’s area rainfall is 0.697 and 0.333 re-spectively. Area rainfall threshold shows that: when yesterday’s flow is relatively little, more area rainfall is needed to form the flow of 500 m3/s or 1000 m3/s; when yesterday’s flow is relatively much, little area rainfall is needed to form the flow of 500 m3/s or 1000 m3/s.

Abstract: 【目的】研究五倍子废渣对小麦生长及产量的影响,并分析施肥对此影响的缓解效应,为寻求生物质加工剩余物(生物质工业废渣)的环境友好型循环利用方式提供参考。【方法】采用盆栽试验,设置0(CK),10,20,30,40,50,60 g/盆7个废渣添加水平,研究在土壤中添加五倍子废渣对小麦形态指标(株高、地径)、抗氧化酶系统(过氧化物酶(POD)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT))、渗透调节物质、产量及其构成因素的影响,分析施肥的缓解效应。【结果】不同添加量五倍子废渣对小麦的生长表现出不同程度的抑制作用。随着废渣分解时间的延长,各处理小麦形态指标的差异性逐渐明显。随着废渣添加量的增加,小麦生长受到的抑制效应逐渐增强。随着废渣分解时间的延长,各处理CAT和SOD活性均呈先升高后降低的趋势,而POD活性则呈逐渐降低的趋势;且高剂量处理的抑制程度强于低剂量处理。随着废渣分解时间的延长,可溶性蛋白含量随着废渣添加量的增加呈下降趋势,而可溶性糖含量则呈上升趋势;到播种后88 d时,各处理含量逐渐恢复至正常水平。低剂量废渣处理对小麦产量表现为促进作用,但随着废渣添加量的增加,其抑制作用逐渐增强,小麦的产量构成指标逐渐降低。施肥处理可一定程度缓解五倍子废渣对小麦生长和产量的影响。【结论】采用施肥的形式,在种植小麦的农田中添加不超过5 240 kg/hm2的五倍子废渣,对小麦生长不会产生明显的抑制作用,且废渣分解后还可发挥有机肥功能,一定程度上可实现“生态友好型”还田的目的。
【Objective】The effects of processing residue of Galla chinensis on growth and yield of Triticum aestivum were studied and the alleviating effects of fertilization were analyzed to provide reference for seeking environment friendly recycling methods of biomass processing residues.【Method】Pot experiment was conducted to study the effects of processing residues of Galla chinensis on growth,antioxidant enzymes,osmotic adjustment substances,yield and its components of wheat (Triticum aestivum) and the alleviating effects of fertilization.The adding amounts of residues were set to 7 levels (treatments) including 0(CK),10,20,30,40,50,and 60 g/pot.【Result】Different amounts of residues showed inhibition on growth of wheat and the differences in morphological indexes in all treatments became clear gradually with the extension of time.With the increase of applying amount of residues,the inhibition was increasingly enhanced.The activities of CAT and SOD increased firstly before decreasing while the activity of POD decreased continuously.The treatments with higher applying amounts had higher inhibition than lower applying amounts.The content of soluble protein (SP) decreased while that of soluble sugar (SS) increased with the increase of residue amount.The contents of SP and SS in all treatments showed no significant differences and gradually restored to normal level 88 days after sowing. With the increase of residue amount,the reproductive growth indexes of wheat gradually reduced,and the inhibition increasingly strengthened.Fertilization relieved the effects of residues on growth and yield of wheat to a certain extent.【Conclusion】Applying gallnut residues with amount of no more than 5 240 kg/hm2 in wheat fields would act as organic fertilizer and achieve eco-friendly returning without affecting the growth of wheat significantly
