华亚 6 号是黑龙江省农业科学院经济作物研究所 2005 年从波兰引进种质资源材料Pekinense变异单株,采用系统选育法以高油、纤维、观赏性强为目标进行定向选择育成的油纤赏兼用型亚麻品种.2019 年通过非主要农作物品种登记,登记编号:GPD亚麻(胡麻)(2019)230011,具有粗脂肪含量高、纤维产量高、高抗枯萎病且观赏性强的优点.

试验对华亚2号、华亚3号、华亚4号、华亚5号、Amine(荷兰)和Vesta(荷兰)6个亚麻品种在2018—2021年内5个关键农艺性状和4个产量性状的变化趋势以及相关性进行分析.结果表明,6个亚麻品种蒴果数和种子产量的变异系数较大,稳定性相对较弱,其余农艺性状均表现出较好的变异性.其中华亚2号、华亚5号、Amine和Vesta干茎制成率的变异系数均小于3％,变异幅度小,稳定性较强.6个亚麻品种的种子产量、纤维产量、原茎产量和全麻率的变化趋势不同:华亚2号、Amine和Vesta亚麻品种种子产量均呈上升趋势;华亚2号、华亚4号、华亚5号和Amine的原茎产量呈上升趋势,其余两种呈略下降趋势;华亚3号纤维产量略下降,其余品种整体呈上升趋势;6个亚麻品种的全麻率变化趋势稳定.相关性分析结果显示,株高、工艺长是影响亚麻原茎产量和纤维产量的最主要因素,与原茎产量和纤维产量均呈极显著正相关(p<0.01),株高和工艺长是影响亚麻产量的重要性状,提高亚麻品种的株高和工艺长是提高纤维产量和原茎产量的有效途径.上述研究为亚麻育种规划、开发高产改良品种提供理论基础.

针对寒地育秧机械化程度低、农村劳动力减少、而水稻种植集中连片经营面积不断增加,以及秧盘育秧摆盘、起秧用工量大,苗床病害严重、育秧成本高和漏插补苗现象等系列问题,本文详细分析了寒地水稻麻育秧膜免秧盘育秧技术.该技术具有省秧田、省人工、省成本、省秧苗,劳动强度小,晚育早插返青快,轻简、节本、节水、环保等优点.寒地水稻麻育秧膜免秧盘育秧技术的推广与应用对实现水稻生产的节本增效和可持续发展具有重大的意义,其社会效益和生态效益显著.

水飞蓟既是保肝护肝的中药又是优质的食用油原料.对新品种北蓟1号的选育过程、特征特性、产量及其栽培技术进行介绍,为水飞蓟的种植提供参考,促进水飞蓟产业的发展.

In order to understand the main weeds species which harm alfalfa production and its occurrence dynamic in autumn of Qingdao area, the species and the dynamic growth were investigated using the methods of census and sampling method of combining in the artificial alfalfa fields of forage base of Qingdao animal science and technology demonstration park from August to October of 2012.The results showed that there were 16 species of weeds in autumn (belonging to 11 families) in the artificial alfalfa fields of Qingdao area, and most of them were annual and perennial weeds in summer.The weed species with large number and higher damaged were gramineae such as Digitaria sanguinalis, Echinochloa crusgalli, Setaira viridis, compositae such as Sphaerotheca fuliginea Poll, amaranthaceae mainly with Amaranthus retroflexus and Cynara cardunculus, chenopodiaceae mainly with Chenopodium glaucum and solanaceae mainly with Solanum nigrum, the dominant species was gramineae.Since August, gramineae and chenopodiaceae weeds already had fruits, and no longer growth, other weeds at seedling stage, vegetative stagen or flowering stage, still in the growth.
