Rice quality is influenced by many factors,viz.,temperature,humidity,atmosphere and storage time.To uncover quality variations of rice after postharvest,we estimated the physicochemical properties and volatile compounds of an indica rice Zhongzheyou 8 under granary conditions(20ºC-25ºC in summer and 10ºC-15ºC in other seasons)for three years.

A field experiment was conducted at the farm of Yangzhou University, Yangzhou, China, to study the effects of organic fertilizers made from maize straw on rice grain yield and the emission of greenhouse gases. Four organic fertilizer treatments were as follows： maize straw （MS）, compost made from maize straw （MC）, methane-generating maize residue （MR）, and black carbon made from maize straw （BC）. These organic fertilizers were applied separately to paddy fields before rice transplanting. No organic fertilizer was applied to the control （CK）. The effects of each organic fertilizer on rice grain yield and emission of greenhouse gases were investigated under two conditions, namely, no nitrogen （N） application （ON） and site-specific N management （SSNM）. Rice grain yields were significantly higher in the MS, MC and MR treatments than those in CK under either ON or SSNM. The MS treatment resulted in the highest grain yield and agronomic N use efficiency. However, no significant difference was observed for these parameters between the BC treatment and CK. The changes in the emissions of methane （CH4） carbon dioxide （co2）, or nitrous oxide （N20） from the fields were similar among all organic fertilizer treatments during the entire rice growing season. The application of each organic fertilizer significantly increased the emission of each greenhouse gas （except N20 emission in the BC treatment） and global warming potential （GWP）. Emissions of all the greenhouse gases and GWP increased under the same organic fertilizer treatment in the presence of N fertilizer, whereas GWP per unit grain yield decreased. The results indicate that the application of organic fertilizer （MS, MC or MR） could increase grain yield, but also could enhance the emissions of greenhouse gases from paddy fields. High grain yield and environmental efficiency could be achieved by applying SSNM with MR.

Light deficiency is a growing abiotic stress in rice production.However,few studies focus on shading effects on grain yield and quality of rice in East China.It is also essential to investigate proper nitrogen(N)application strategies that can effectively alleviate the negative impacts of light deficiency on grain yield and quality in rice.A two-year field experiment was conducted to explore the effects of shading(non-shading and shading from heading to maturity)and panicle N application(NDP,decreased panicle N rate;NMP,medium panicle N rate;NIP,increased panicle N rate)treatments on rice yield-and quality-related characteristics.compared with non-shading,shading resulted in a 9.5-14.8%yield loss(Pgrain percentage and grain weight.NMP and NIP had higher(Pgrain yield than NDP under non-shading,and no significant difference was observed in rice grain yield among NDP,NMP,and NIP under shading.compared with NMP and NIP,NDP achieved less yield loss under shading because of the increased filled-grain percentage and grain weight.Shading reduced leaf photosynthetic rate after heading,as well as shoot biomass weight at maturity,shoot biomass accumulation from heading to maturity,and nonstructural carbohydrate(NSC)content in the stem at maturity(Preserve of NDP were increased under shading.Shading decreased(Pcontent while increasing(Pgrain protein.NMP demonstrated a better milling quality under non-shading,while NDP demonstrated under shading.NDP exhibited both lower chalky rice percentage,chalky area,and chalky degree under non-shading and shading,compared with NMP and NIP.NDP under shading decreased amylose content and breakdown but increased grain protein content and setback,contributing to similar overall palatability to non-shading.Our results suggested severe grain yield and quality penalty of rice when subj

目的:调查在盐城生物圈保护区越冬的丹顶鹤食物是否受到真菌毒素污染以及评估丹顶鹤受到真菌毒素威胁的风险。创新点:首次证明在盐城生物圈保护区越冬的丹顶鹤受到真菌毒素的威胁。方法:2013年11月至2015年3月,两个越冬期内在盐城生物圈保护区采集丹顶鹤不同觅食生境内113份食物样品。使用高效液相色谱法对这些食物中毒素(黄曲霉毒素B1(AFB1)、脱氧雪腐镰刀菌烯醇(DON)、玉米赤霉烯酮(ZEN)、T-2毒素(T-2)和赭曲霉毒素A(OTA))含量进行检测。结论:盐城生物圈保护区内丹顶鹤食物受到真菌毒素的污染,人工湿地尤其是稻田不适宜作为鸟类的觅食地。
