‘闽甜4号’玉米种植密度对主要农艺、商品性状及经济效益的影响

以甜玉米新品种‘闽甜4号’为材料,研究不同种植密度对其主要农艺、商品性状及经济效益的影响。结果表明,栽培密度在每公顷4．95万株时,鲜苞商品性状和产量能够得到比较好的协调,取得好的效益。密度过高会影响鲜苞商品性状,密度过低影响产量。     

无竹令人俗-记新型竹制儿童玩具开发设计

将竹子这种环保材料应用于儿童玩具设计是未来玩具设计的一个大的趋势。详细描述了3款系列竹制儿童玩具设计的整个设计制作过程,该设计的主要创新点在于将毛绒玩具和竹子材料结合起来,形态非常讨喜。不足之处在于,在玩法设计方面考虑不够深入和详细。

Toxicity and protectant potential of camphor,a major component of essential oil of Ocimum kilimandscharicum,against four stored product beetles

The biological activity of camphor, a major component of essential oil of the basil shrub, Ocimum kilimandscharicum, against the beetles, Sitophilus granarius, S. zeamais, Tribolium castaneum and Prostephanus truncatus, was investigated in the laboratory using contact toxicity, grain treatment and repellency assays. Camphor applied either topically, impregnated on filter papers or whole wheat and maize grains was highly toxic to all the four species. Beetle mortality was dosage-dependent with the highest doses of 100 mg/ filter paper and 100 mug/insect evoking over 93% and 100% mortalities, respectively, in S. granarius, S. zeamais and P. truncatus after 24 h exposure. Similar doses induced 70% and 100% mortality in T. castaneum. Camphor impregnated on the grain surface was more effective than on filter paper. There was, however, highly significant reduction in toxicity in grain after only 24 h following treatment. Development of eggs and immature stages within grain kernels, as well as progeny emergence, was completely inhibited in camphor-treated grain. Camphor was also highly repellent to the beetles with overall repellency in the range of 80 - 100%. The potential use of suitable products derived from O. kilimandscharicum as supplementary or alternative grain protectants against insect damage in traditional grain storage in developing countries is discussed.     

冰淇淋电脑配合优化模型研究

本文以最小化原料成本为目标函数;以乳脂肪、非脂乳固体、糖分、总固形物等质量关系设立8个约束方程,建立了最优化冰淇淋线性规划模型,在计算机上,利用该模型配合出市场选料、企业定料情况下的高、中、低档牛奶和水牛奶优化冰淇淋配方。并模拟市场原料价格和成分质量实际变化,检验了模型配方调整灵敏度反应。得出电脑模型技术配合冰淇淋配方比目前企业广泛使用的皮尔逊法、代数法快速准确,节约成本和满足产品多方面质量要求。
