脱毒马铃薯的商品性及增产效果试验初探

对紫花851、中薯3号等马铃薯脱毒种薯与非脱毒种薯进行比较试验,结果表明：脱毒-5铃薯种薯抗病性、商品性明显优于非脱毒种薯,脱毒品种能有效地减少块茎小薯率、露青薯率及裂薯率,产量也极显著地高于非脱毒种薯。     

Comparison of Moist and Dry Cooking on Sensory Quality,Consumer Acceptance and Marketability of Canned Bighead Carp

Abstract

Canned bighead carp has shown potential as a freshwater fish product. Canned products made from bighead carp loins that had been either cooked in steam or a convection oven were evaluated by a consumer panel of 90 individuals. The consumers were not told the identity of the fish under consideration. Acceptability was estimated by use of hedonic scales for sensory attributes, open-ended questions about how the products compared to similar canned fish products, and the just right scale for attribute direction for change. Willingness to pay compared to similar products also was determined for each product. Both carp products were light in color and contained less than 1% crude lipids. Acceptability of both products was good with the steam-cooked carp products being slightly more preferred in most categories. For the sensory attribute, “overall liking,” 54% of panelists rated the steam-cooked product as either like very much or like moderately. Likewise, over 60% of panelists indicated that either carp product was better than or equal to canned tuna and that they would be willing to pay as much for either product as tuna.     

农业特色小镇建设背景下的农民市场能力培育

在农业特色小镇建设背景下,农民市场能力培育是一个亟待深入探究的具体问题。H市三个农业特色小镇建设实践揭示出当前农业特色小镇建设中农民市场能力匮乏的根源在于市场经济抽象价值观的缺乏、社区市场环境孕育不足和浓厚的行政主导色彩。可从个体市场能力培育、新型小镇社区营造和制度支持体系构建等三个维度实现农民市场能力的培育。农民市场能力培育是农业特色小镇等乡村发展项目实践中必须解决的实际问题,也是需要持续推进的跨学科研究领域。     

不同种植密度、采收期对“夏绿妃”小白菜的影响

通过对夏绿妃小白菜在不同种植密度、采收期条件下产量和商品性的试验测定,结果表明：夏绿妃小白菜在福建省平原地区夏季栽培,适宜的种植密度为株行距7.5～15.0 cm;株行距为7.5～10.0 cm和12.5～15.0 cm时,适宜的采收期分别为22～28 d和25～31 d;高密度种植条件下适时早收有望获得较高产量,采收期延后其商品性急剧下降。
