16737761_黑龙港低平原地区涝害条件下春大豆高产品种的筛选及其农艺性状
近年来，我国大豆播种面积和产量呈逐年下降趋势，2006~2014年全国大豆播种面积和产量的降幅分别为26.9%和19.4%，而同期大豆及大豆替代品的进口量却逐年攀升；2006~2015年河北省大豆播种面积减少了45.1%，产量下降了42.8%[1]。
黑龙港低平原区是我国传统的大豆种植区，近年来，由于主栽大豆品种产量低、品种更新换代慢、退化严重，导致大豆种植面积和产量不断下滑[2]。
同时，该区域降雨量年际间变化剧烈，具有明显的丰枯交替周期[3]，尤其是21世纪以来进入丰水期[4]，涝害发生频繁。
涝害会导致大豆根系缺氧，引发根系发育不良、落花落荚、百粒重下降、病害严重甚至死亡，给大豆生产带来严重损失[5]。
因此，筛选产量高、耐涝性强的大豆品种，对当地大豆生产的发展具有重要意义。
2016年黑龙港低平原地区发生严重涝灾，通过对中国农业大学吴桥实验站种植的16份春大豆品种进行产量及农艺性状分析，以筛选适宜该地区种植的高产、耐涝大豆品种，可为黑龙港地区农业种植结构调整提供支持。
1材料与方法1.1试验区概况试验于2016年在河北吴桥中国农业大学吴桥实摘要：涝害是黑龙港春大豆面临的主要自然灾害之一，引进和筛选高产耐涝品种是解决这一问题的重要措施。
采用大田比较试验，在涝害发生情况下，对黑龙港低平原地区种植的16份大豆品种进行了产量和农艺性状测定；并采用平方Euclidean 距离法，对参试品种进行了聚类分析。
结果表明：沈农27、沈农24、中黄30、沈农22和沈农28属于高产类型，其平均产量为2057.8kg/hm 2，尤其是沈农22，产量高达2233.3kg/hm 2。
这5个品种表现出单株荚数多、单荚粒数多、荚长短的高产耐涝特性，可在黑龙港低平原地区推广种植。

2022-2022年大豆市场行情预测及回顾分析
大豆市场行情回顾分析
2022年至2022年大豆市场回顾与展望：供需失衡，价格 波动
大豆市场行情回顾与分析
2022年至2022年，大豆市场经历了起伏不定的行情。以下是对这一市场情况的回顾和分析。 首先，让我们回顾一下2022年的大豆市场情况。这一年，全球大豆需求持续增长，但由于供应过剩，大豆价格下 跌。美国大豆产量增加，加上南美大豆丰收，使得全球大豆供应充足。国内方面，虽然政策鼓励种植大豆，但由于 玉米和小麦等农作物价格高企，农民种植积极性不高，导致大豆种植面积减少。
政策因素对大豆市场的影响也不可忽视。例如，一些国家可能会通过政策鼓励种植大豆以提高其国内供应，而一些国家则可能会通过政策限制进口大豆以保护本国农业。此外，一些国家可能会通过政策鼓励使用生物燃料来减少 碳排放。这些政策变化都可能对未来大豆市场产生重要影响。

再次，天气风险对大豆市场的影响不可忽视。任何旱灾、洪涝、霜冻、虫害等自然灾害都可能影响大豆的产量和质量，从而影响 价格。例如，2021年巴西的大豆产量受到严重影响，就是因为当年遭遇了严重的干旱。
最后，投机因素也是影响大豆市场的重要因素。在金融市场，大豆经常被用作投机工具。金融市场的波动性可能会对大豆价格产 生重大影响。

大豆市场行情预测
1.2022-2023年全球大豆市场复杂多变
2022年至2023年，全球大豆市场经历了复杂多变的行情。首先，我们从全球供需角度来看。由于全球 气候变化导致的天气条件多样化，种植季节的降雨量和温度，以及病虫害的影响，都将对大豆的产量产 生重要影响。而种植季节的气候条件可能对全球大豆供应产生重大影响。例如，干旱可能导致某些地区 的产量下降，而洪水等极端天气事件可能导致某些地区的产量增加。 其次，我们需要关注的是政策因素。例如，政府对农业的政策调整，包括补贴、税收等，可能会对大豆 市场的价格产生重大影响。另外，贸易政策的变化也可能对大豆市场的供需平衡产生影响。例如，贸易 保护主义政策的实施可能会使全球大豆市场变得更加紧张。

托福改革后听力考试内容组成详解及题型分值介绍
托福改革后听力考试内容组成详解及题型分值介绍托福改革后听力考试内容组成详解及题型分值介绍托福听力考试内容讲解托福听力考试部分的考试时间通常为41-57分钟，听力考试的题型大致可分为对话和讲座两个类型。
每段听力内容的时间大致都在4到6分钟左右。
对话部分，托福听力每场考试一般有2-3个对话，每段对话后设有5个问题。
在对话中，第一个场景一般发生在学校办公室里。
对话可能涉及学术内容或者与课程要求有关。
第二、三个场景是关于学生的日常对话。
对话一般发生在大学校园中，包括非学术性的内容。
当然这个并非绝对，对话的具体内容也可能会出现一些变化。
除了对话外，另一种将做形式的托福听力题型则包含3到4个讲座(Lectures)，每个讲座后会有6个问题。
讲座一般来源于讲师教授的课堂教学内容。
讲座可能只是摘录教授的讲课内容，或者是学生的提问，或是老师向学生提问并且请一位学生回答。
这个题型更偏向于学术性的内容。
当然，在这里需要提示大家一下，听录音的过程中，ETS允许大家记录笔记。
所以，备考听力过程中，学会如何记录笔记，对于托福听力的提分是很有帮助的。
托福听力评分标准解读在托福听力中所有回答正确的题目数量加起来就是你的“total points”。
而托福听力的评分标准和出题形式大致可以总结为以下3点：1.分值是1分的题目，所有的项目都要回答正确，这一题才算是拿到了全部分值。
2.分值是2分的题目，比如，四选三的题目，必须全部答对才能得到所有分值;选对2个，可得到1个分值。
3.托福听力以单选题为主，复选题和表格题为辅。
2020托福听力练习：人工养殖鳟鱼以满足食用需求Half of all fish people eat worldwide now e from fish farms. So farms need to do more to keep up with demand."If we look to the future, at today's per capita fish intake around the world we would need to double aquaculture production."Ron Hardy is the University of Idaho's Director of Aquaculture Research. He presented his research at the recent International Symposium on Fish Nutrition and Feeding in Sun Valley, Idaho, which he also chaired.In the wild, rainbow trout eat insects and other, smaller fish. But Hardy says there aren't enoughlittle fish to feed larger fish in the wild and still meet market demand as the human population increases. So he's used selective breeding to create strains of farmed fish that get by on food that's less expensive than little fish—feed made from soybeans, corn and wheat.Some of the farmed fish really thrive: 16 years ago, Hardy had to wait a year for a one-pound trout. These days, his efforts yield trout up to four times as large in the same amount of time."So, it would be kind of like if you were going to breed dogs. So we've got everything from Rottweilers to little Scotties or whatever."But the farmed fish are not pletely vegetarian."Soybeans don't have skeletons, they don't have bones and the bones in fish meal are a major source of minerals for the fish, for example."And much like humans, fish diets require omega-3 fatty acids, not found in terrestrial plants. So Hardy has to add a little fish-oil back into the plant-based feed. For those of us without waders, this kind of aquaculture is our best shot at a fish fry.现在全世界人们食用的鱼中，有一半来自养鱼场。
美豆定价的回归分析法
美豆定价的回归分析法:利用产量、库存消费比和CRB指数【2014-11-18】国内豆类市场是美国CBOT大豆市场的影子市场，研究和预测CBOT大豆的价格是分析豆类市场的重中之重。
豆类期货价格研究非常重视基本面因素的分析，重视跟踪和预测美国农业部供需数据。
如何利用供需因素变化来预测价格，如何量化各个供需因素变动对价格影响的大小，难以用定性分析来解决，需要进行定量分析。
美豆供需格局主导国际大豆价格美国CBOT大豆市场是国际大豆的定价中心，美国CBOT大豆价格是全球大豆价格的方向标。
CBOT价格作为全球大豆的最权威价格，反映全球大豆市场的供需关系变化，全球大豆贸易也以美国CBOT价格作为定价基准。
全球大豆主产地主要在美国和南美地区，美国大豆年增产速度在下降，而南美大豆产量逐年增加。
虽然当前美国依然是全球最大的大豆生产国，2014/2015年度产量预计达1.07亿吨，但最近几年种植面积增加较小，产量的增长潜力较弱。
南美大豆方面，南美耕地丰裕，大豆种植面积持续增长，近10年来增加近50%。
2014/2015年度巴西大豆产量预计达到9400万吨，而其产量近几年内或超过美国。
2014/2015年度阿根廷大豆产量预计为5500万吨。
随着南美大豆出口量的增加，南美大豆对国际大豆价格的影响力也在增强。
中国是全球大豆第四大生产国，年度产量维持在1200万吨左右，但最近几年玉米种植面积大幅增加，大豆种植面积缩减，大豆产量持续下滑，国产大豆供需关系对全球大豆价格的影响力逐步弱化。
不过中国是全球最大的大豆进口国，当前年进口量达到6000万吨，是国际大豆价格定价的重要参与方。
按照供需因素分析，影响大豆的因素主要有产量、库存、进出口和消费等，其中种植面积、天气和单产是决定产量的主要因素。
大豆作为大宗商品之一，受到的影响因素较多，可量化的供需因素之外，种植成本、通胀等也是重要的影响参数。
由于美国CBOT市场主要参与者为美国的企业和个人，美国本土的大豆生产情况是CBOT 大豆期货价格波动的主导因素，南美大豆的竞争关系也反映到美豆的出口和库存变化上，中国大豆的需求则反映到美豆的出口变化上，所以美豆的库存和出口变化基本反映了全球大豆的供需情况。

Abstract: NAC genes play an important role in plant stress tolerance. In this study, bioinformatic method was used to identify the stress related GmNAC gene in soybean. The expression of candidated GmNAC genes in root and leaf was analyzed in soybean with NaCl treatment by Real-time PCR. Reverse transcription PCR was performed to clone genes with significant difference in expression. The results showed that there were 175 genes in soybean GmNAC gene family. There were 11 GmNAC proteins with highly conserved NAC located on the same evolutionary branch with the stress related NAC proteins in rice and Arabidopsis. The expression of 11 GmNAC genes in soybean root was higher than that in leaf. The GmNAC genes were all induced by NaCl stress, but part of the GmNAC genes showed different expression levels between root and leaf in soybean varieties with different salt tolerances. There were three synonymous mutations and one non-synonymous mutation on the CDS region of Glyma06g11970.1 and one synonymous mutation on the CDS region of Glyma06g16440.2 in Qihuang 34, Xudou 10, and Fendou 95.

11年豆类品种走势分析
10/11年度国内外大豆、豆粕、豆油价格的走势分析分析结论：10/11年度大豆、豆粕、豆油会在目前的价格附近继续震荡上行，而且会刷新三年前的历史高点，重创新高。
这主要是由其本身供求基本状况所决定的。
一．10/11年度美国大豆的供求状况1. 10/11年度美国大豆的供应状况2010年12月10日，美国农业部公布了最新的10/11年度美国大豆供求数据报告，美国农业部预计10/11年度美国大豆期初库存为1.51亿蒲式耳，美国大豆进口为0.1亿蒲式耳，美国大豆产量为33.75亿蒲式耳，美国大豆的总供给为35.36亿蒲式耳。
我们认为10/11年度美国大豆总供应量达不到35.36亿蒲式耳，这主要是由于10/11年度中，美国大豆的总产量达不到33.75亿蒲式耳。
由于2010年7~8月美国最大的大豆生产州——衣阿华连降暴雨，淹没了大片农田，不仅使该州的玉米产量大幅下降，也使大豆产量受到严重影响。
同时美国大豆主产地中西部的南部，又受到干旱的困扰，致使那里的大豆产量也受到严重的影响。
尽管美国其它的大豆产区天气良好，大豆产量创下新高，还是难以扭转10/11年度美国大豆单产低于09/10年度的趋势，并且使10/11年度美国的大豆收割面积低于预期。
预计美国农业部会在2011年1月份的大豆月度供求报告中，继续下调10/11年度美国的大豆单产或大豆收割面积。
美国农业部将会在2011年1月份的大豆月度供求报告中，把10/11年度美国的大豆单产下调到43.5蒲式耳以下，大豆总产下调到33.40亿蒲式耳左右，使其低于09/10年度33.59亿蒲式耳的大豆总产量。
因此，我们预计10/11年度美国大豆的总供给将在35亿蒲式耳左右，低于09/10年度的35.12亿蒲式耳的数量。
2. 10/11年度美国大豆的需求状况2010年12月10日，美国农业部预计10/11年度，美国大豆的总需求为33.71亿蒲式耳。
其中美国大豆压榨需求为16.65亿蒲式耳，美国大豆出口需求为15.9亿蒲式耳，美国大豆种用需求为0.88亿蒲式耳，美国大豆调整值需求为0.29亿蒲式耳。

预计豆类走势震荡偏强
预计豆类走势震荡偏强作者：王朱莹来源：《农产品市场周刊》 2018年第10期经历了38年来最干旱2月的阿根廷，阿根廷布宜诺斯艾利斯省交易所再将大豆产量下调300万吨预估至4400万吨，由此点燃了豆类尤其是豆粕期货的多头行情。
市场认为，这都归结于拉尼娜。
但美国海洋大气管理局( NOAA)近期发文指出，大多数计算机模型预见到了拉尼娜的衰退，拉尼娜在3～5月消退的可能性已经达到55%。
那么，豆粕期货的“天气行情”会否就此终结呢？“圣女”来了走了“圣婴”厄尔尼诺，来了“圣女”拉尼娜，期货市场刮起了一场“豆旋风”。
2月6日以来，国内豆粕期货大幅上涨，主力1805合约累计涨幅达12.68%；同期，CBOT豆粕涨幅也高达18.66%。
国投安信期货分析师李青表示，此轮粕价大涨的成因可以归结为三个方面。
其一，当前备受市场关注的阿根廷大豆主产区干旱炒作，这也是最重要的原因。
其二，美国农业部( USDA)2月份供需报告偏多。
在最新USDA供需报告中，巴西大豆产量调增悉数冲抵了阿根廷大豆减产的损失，不过，从全球范围来看，总库存的意外下修对豆类期价构筑中性偏多影响。
其三，国内进口豆压力“前高后低”。
从往年季节性规律来看，2月适逢春节长假，进口豆到港量将降至年内冰点，3月之后随着节后需求重燃，月度进口量将渐次走升。
阿根廷旱魃肆虐，遭遇38年来最干旱的2月。
截至3月初，占阿根廷大豆产量八成以上的三大大豆主产区之中，除了布宜诺斯艾利斯省土壤墒情好于2008/2009年同期之外，科尔多瓦和圣菲两省旱情均触及2008/2009年同期程度。
阿根廷同样是豆油的主要出口国，但从盘面上看，干旱对豆油产生的积极影响十分有限。
2月6日以来，豆油主力1805合约涨幅仅4.35%。
上海东亚期货研发中心研究部经理许亮表示，这主要是因为油脂总体供应宽松，尤其是棕榈油主产国马来西亚和印尼步入增产周期，库存创出新高。
同时，豆油在油脂消费的比重大约在30%左右，而豆粕在整体蛋白类消费的比重达到了66%。

大豆百粒重QTL定位
大豆是我国主要农作物之一, 已成为世界上最 丰富而价廉物美的蛋白质与油脂资源, 是具有高经 济性与高营养性的农作物。大豆在作为饲料用、食 用等多方面都具有广泛的用途, 大豆食品在国际市 场上的需求也日益增多。大豆百粒重是大豆产量的 重要因素, 是一个重要的复杂性状, 易受环境影响,
表型选择的准确度不高。随着分子标记技术的发展, 检测百粒重的基因座, 发展大豆分子标记辅助选择 技术对于大豆高产育种具有重要意义。

雷等[5]利用科丰 1 号×南农 1138-2 的 RIL 群体发现 了 6 个百粒重 QTL, 但每个 QTL 的遗传加性效应都 不高, 可解释的变异在 6.6%~16.0%之间。Zhang 等 [4]利用同一 RIL 群体发现了 4 个百粒重 QTL, 位于 A2、B1、D2 连锁群上, 其中在 D2 连锁群上的 QTL 能解释变异的 11.4%。Reinprecht 等[6]利用 F5 株系组 成的 RIL 群体在 2 年 3 点的试验中检测到 7 个百粒 重 QTL。黄中文等[7]利用科丰 1 号和南农 1138-2 所 衍生的 184 个重组自交家系 2 年的试验结果检测到 6 个百粒重 QTL, 分别位于 A2、B1、C1、O2 连锁 群上。然而, 至今未见其核质互作 QTL 定位的报道。
