种植密度对机播条件下红玫瑰马铃薯结薯性状及产量的影响

为确定临沂市机播条件下红玫瑰彩色马铃薯的最佳播种密度,开展了机播马铃薯相同行距(90 cm)、不同株距(14、18、22、26 cm)的密度试验,分析了不同密度处理对红玫瑰马铃薯出苗期、现蕾期、开花期、成熟期、株高、茎粗、主茎数、马铃薯晚疫病发病情况、产量、商品薯率的影响。结果表明:随着播种密度的增加,红玫瑰物候期无明显变化,株高、马铃薯晚疫病株数呈升高趋势,茎粗和主茎数呈降低趋势,商品薯率和商品薯产量呈下降趋势。以行距90 cm、株距22 cm密度下商品薯667 m~2产量最高,为2 129.25 kg,并且马铃薯晚疫病未见发生。     

我国银行存款保险制度的路径选择研究

明确存款保险制度应当作为我国金融安全的重要组成部分。基于风险定价的存款保险费应当由政府和银行共同承担。政府提供的隐性存款保险随着存款保险制度完善逐步减少，为银行积累资本赢得时间。银行应当通过充实资本，降低存款保险费，为实施明确存款保险创造条件。我国最终应当建立信息透明、市场机制主导、政府严格监管、风险处置及时的明确存款保险制度。     

Volatile profile,fatty acids composition and total phenolics content of brewers' spent grain by-product with potential use in the development of new functional foods

Brewers' spent grain (BSG) is the insoluble residue generated from the production of wort in the brewing industry. This plant-derived by-product is known to contain significant amounts of valuable components, which remain unexploited in the brewing processes. Therefore, it is essential to develop a more detailed characterization of BSG in order to highlight its potential in developing new value-added products and simultaneously solve the environmental problems related to its discharge. The content of BSG in several biologically active compounds (fatty acids, polyphenols, flavonoids, antioxidant capacity) as well as its volatile fingerprint were assessed and compared with the composition of barley, malt and wheat flour samples. The obtained results emphasized the importance and the opportunities of the re-use of this agro-industrial by-product.     

Feasibility analysis of NIR for detecting sweet corn seeds vigor

This paper explores the feasibility of particle-based detection and grading of seed vigor based on a self-built seed single-granulation device using near infrared spectroscopy (NIRS). Sweet corn with uniform kernel size was used for this study. The seed samples were divided into three types, they were normal seeds, artificially aged seeds and heat-damaged seeds. A 2-part spectral acquisition of each seed were performed, one for the collection of seeds that fall into the detection zone within the separation pipe, another was on the static platform, whose collection was performed on 5 faces of each seed. Partial least squares discriminant analysis (PLS-DA) was used to classify the original data of the seeds. In the 2 parts, the discriminant results of the unprocessed normal seeds and the artificial accelerated aging seeds, the untreated normal seeds and the heat-damaged seeds showed that classification accuracy was higher than 98%. The research indicates that the spectral data of different positions of seeds can reflect their activity information, and it is feasible to detect and classify seeds in real time in the detection area of the separation pipeline.

氮素营养对马铃薯产量形成特性及品质的影响

为优化旱作马铃薯氮素施用量,进一步提高马铃薯产量和改善薯块品质,通过盆栽种植方式,研究氮素营养对马铃薯干物质积累量、根冠比、产量及薯块品质的影响。结果表明:施氮量为190 kg/hm~2时,马铃薯各生育时期干物质积累量、根冠比和单株产量最高,根据一元二次拟合方程得出最佳施氮量为206.39 kg/hm~2,此时马铃薯单株产量为388.22 g,与实际最佳施氮量接近;马铃薯薯块淀粉和VC含量均在施氮量为190 kg/hm~2时最高,薯块蛋白质含量随氮素的增加呈递增趋势,而有机酸含量随氮素增加呈先增后降的趋势,在施氮量为350 kg/hm~2时达到最大值。在试验条件下,综合分析马铃薯产量形成特性及各品质指标,马铃薯氮素最适施用量为190~206.39 kg/hm~2。
