采用GC-MS法检测了处理扑草净生产的东当归、桔梗、轮叶党参、地黄块根中的扑草净残留量.测定结果,扑草净(40%)春季土壤处理2和4kg·hmr.2剂量时,秋季(施药后152d)烘干的东当归块根中扑草净残留量分别为0.0368和0.0464mg·kg-1,桔梗块根中分别为0.0276和0.0358mg·kg-1,轮叶党参块根中分别为0.0235和0.0343mg·kg-1,地黄块根中分别为0.0427和0.0590mg·kg-1.

为探求更加快捷、有效的芝麻区域试验分析方法,利用2012年全国(北方片)芝麻区试结果,通过方差分析法、回归分析法、高稳系数法、AMMI模型分析法四种方法,对7个参试品种(系)进行丰产性和稳产性分析.结果表明,冀200401具有较好的丰产性和稳产性,是一个比较理想的高产稳产芝麻品种(系);四种分析方法得出的结论基本一致,但又不尽相同;高稳系数法和AMMI模型分析方法综合功能强,对品种评价更加客观、全
运用五元二次回归正交旋转组合设计,研究甘蓝型油菜中双1号的种植密度,氮、磷、钾肥施用量及氮肥施用期等五个主要栽培因子与菜籽产量之间的效应关系及其数学模型;采用频率分析法,借助计算机进行模拟仿真试验,在具有95%置信度的各因素取值范围,优选出每667m2产菜籽220~240kg、240~260kg、260~280kg三个产量区间相应的农艺措施组合方案,并得到较好验证.
通过PEG-6000模拟干旱胁迫,对6个甘蓝型油菜品种的抗旱性进行鉴定及大田五叶期冠层覆盖面积、总生物量干重和根系干重分析.结果表明,EV2的抗旱指数最大,EV6的抗旱指数最小;EV2的冠层覆盖面积最大,与其它品种之间存在极显著性差异,总生物量以EV2、EV3和EV1较大,根系干重以EV2较大,而且三者之间存在显著相关性;对抗旱指数进行通径分析,冠层覆盖面积对抗旱性的直接通径系数最大,达到0.59
以云油杂2号杂交品种为材料,在大田育苗移栽条件下,设置不同密度、播种期、打薹时期等多因素的正交试验,根据试验结果,提出优化的"菜油两用"技术是密度12万株/hm2,9月中下旬播种,现蕾期摘薹综合经济效益最高.
