富硒油菜优质高产栽培组装配套技术

湖南省桃源县是全国油菜优势区域县,也是湖南省油菜产业大县之一。油菜是涉及国计民生的重要商品,是桃源县冬季农业开发的主要作物。近些年,随着农业部、省农业厅在桃源县油菜"万亩高产创建示范片"活动的开展,全县的油菜生产常年面积稳定在5.28万公顷左右,油菜籽总产10.29万吨左     

预计2012年新季油菜籽收购价将高开高走

新季油菜籽就要上市了,预计今年新季油菜籽收购价格将高开高走,但向上空间有限。其理由：一是受利益驱动,农民期望值较高,加之种植成本上升,农民有惜售观望心理;二是企业产能过剩导致供需不匹配,抢购风拉动价格上涨;     

农业部启动粮食增产模式试点

农业部10月30日启动粮食增产模式试点工作,并提出力争到2020年粮食增产1000亿斤以上、油菜籽增产500万吨以上。     

在积累镉油菜后茬种植白菜可否减少其对镉的吸收?

Rapeseed (Brassica campestris L.), a Cd-accumulating crop, is effective in reducing plant-available Cd from soil. A pot experiment was conducted to test the hypothesis that the Cd uptake by Chinese cabbage (Brassica pekinensis Rupr.) grown in rotation with rapeseed would be reduced due to the efficient removal of bioavailable Cd from soil solution by the rapeseed crops. The Cd removal by shoot for the rapeseed cultivar Zhucang Huazi ranged from 0.24% to 0.99% in natural Cd-contaminated soil (soil A) and from 0.63% to 1.23% in artificial Cd-contaminated soil (soil B) during the growth period of 4–7 weeks; whereas that for the rapeseed cultivar Chuanyou II-93 ranged from 0.25% to 0.66% and from 0.38% to 1.02%, respectively. Chinese cabbage grown in the pots with soil A for five weeks after harvesting rapeseed exhibited a significantly lower Cd concentration compared to that grown in the control pots (uncropped with rapeseed). However, the rotation of rapeseed did not lower the Cd concentration of Chinese cabbage on soil B. Although an increase of Cd uptake was observed in the rapeseed cultivars with growth time, and the decrease of soil NH 4 OAc-extractable Cd was found only in the natural rather than artificial Cd-contaminated soil.     

新收获油菜籽应急处理的探讨

油菜籽是我国主要的油料作物之一,含有丰富的油脂和优良的蛋白质,油菜籽中含有21%～24%的蛋白质[1],含油率高达40%～45%[2],油菜籽颗粒间孔隙小[3],储藏不当极易发热、生虫、霉变、酸败而影响油菜籽的出油率和油脂的品质[4]。由于冬油菜籽成熟季节在5、6月份,收获     

国内转基因食品有哪些?

网上流传一份"转基因食品鉴别手册",其中提及目前国内市场上常见的圣女果、大个儿彩椒、小黄瓜、小南瓜等都是"隐藏在生活中"的转基因食品。这份名单是否属实?目前国内市场在售的转基因食品有哪些?对此,中国农科院生物技术研究所研究员、生物安全研究室主任王志兴近日在接受采访时列出国内转基因食品清单。
