本文报道了微量元素钼对纸筒育苗甜菜的生长及产质量的影响。试验在新疆奇台农业试验站进行。每册纸筒施钼酸铵数量分别为2.5克、7.5克、12.5克、17.5克和22.5克。各种用量的钼酸铵均使甜菜的叶绿素含量下降、过氧化氢酶活性降低。随着施钼酸铵量增加,甜菜幼苗的生长受到抑制,根产量降低,只有每册纸筒施钼酸铵2.5克和7.5克的甜菜根产量比对照高22.2％和18.8％,各处理对甜菜含糖率的影响不大。
This paper reports the effect of trace element molybdenum on the growth, yield and quality of paper-growing seedlings. The experiment was conducted at Qitai Agricultural Experiment Station in Xinjiang. The volumes of ammonium molybdate per paper roll were 2.5 grams, 7.5 grams, 12.5 grams, 17.5 grams, and 22.5 grams, respectively. Various amounts of ammonium molybdate so that the sugar beet chlorophyll content decreased catalase activity decreased. With the increasing amount of ammonium molybdate, the growth of sugar beet seedlings was inhibited and the root yield was reduced. Only 2.5 grams of ammonium molybdate and 7.5 grams of beetroot were produced per paperboard respectively. The yield of beetroot was 22.2% and 18.8% higher than that of the control. Sugar beet has little effect.

我国黄淮冬麦区在小麦开花后常受阴雨寡照的影响，且小麦生产中存在群体过大，小麦生育后期群体内光照不足等问题，严重影响了小麦的产量和籽粒的品质。因此，本研究选用不同穗型的小麦品种，通过设置花后不同强度和不同时期遮光从农艺、生理和生化性状上系统研究花后弱光对小麦籽粒产量形成、衰老和氮素积累转运的影响。进一步明确花后弱光下，小麦生长发育的生理生化的变化。主要研究结果如下：1花后不同强度遮光对小麦光合特性和
油菜是世界范围内重要的油料作物之一,其产量和品质相关性状的遗传机理一直是人们研究的重点。这些性状多为数量性状,受多基因控制及对环境敏感,很难对它们开展深入的研究。近年来,高通量SNP的开发和高密度遗传连锁图的利用为准确定位QTL提供了有效的手段。本实验室利用M201(高含油量品系)和352(低含油量品系)两个材料作为亲本,创建了一个包含192个株系的重组自交系群体。在此基础上,在一个半冬性环境(湖
