To clarify the quality characters,understand the genetic diversity and screen elite lines among different oilseed sunflowers,the contents of crude fat,oleic acid,linoleic acid,palmitic acid and stearic acid of 525 oil sunflowers(including 375 germplasm accessions and 150 inbred lines)were detected by near-infrared spectroscopy(NIRS);the genetic variation and correlation analysis of quality traits were also *** results showed that oleic acid and linoleic acid had rich diversities with large variation ranges for each material *** to the relation between crude fat content and palmitic acid content,significantly negative relation with high estimated value existed between oleic acid and linoleic acid content,while stearic acid content positively associated with oleic acid and palmitic acid *** component analysis indicated that 5 quality traits were integrated into 2principal component factors(linoleic acid negative factor and palmitic acid factor)with the contribution rate of 88.191%,which could be used for evaluating sunflower quality.525 oilseed sunflowers were clustered into 3groups with obvious differences of quality characters,materials in Group I had high contents of oleic acid and low crude fat,but the opposite was found in GroupⅢ.59 superior quality accessions were obtained using large-scale and rapid near-infrared spectroscopy,and these excellent materials were verified by the traditional national chemical standard *** research provided materials and significant reference for sunflower genetic research and quality breeding.

To evaluate effects of plastic film mulching on soil moisture, majority root distribution and water use efficiency (WUE), experiment was designed in flax field of Gansu,China. Three treatments including flat drill without mulching (CK), whole field soil plastic film mulched which covered with soil and bunch seeded (T1), and ridges mulched with plastic film and row-seeding in furrows (T2) were tested. Results indicated that mulching practice increased soil water storage compared to CK treatment in general. In both topsoil (0-30 cm) and underlying soil (30-100 cm) layer, T1 treatment had significantly greater (P<0.05) water storage than that in CK and T2 treatment. T1 treatment increased most significantly of soil water storage in 0-100 cm soil layer after rain, and also maintained high soil moisture at flax mature stage. Compared to CK, T1 and T2 produced obviously larger (P<0.05) taproot diameter and greater dry weight at both juvenile growth stage and first flowering stage, but had shorter lateral root length at all three stages. Consequently, seed yields and WUE with mulching treatment were increased by 22.3%-38.8% for T1 and 35.4%-56.2% for T2 compared to CK respectively. Film mulching is an effective cropping system for flax production in semiarid areas for improved root growth and enhanced soil moisture at different soil depths.

为明确不同浓度的化学药剂对蓖麻性别的影响,本试验以蓖麻两性系(E09004、E09009和E09002)和E09002单雌系为材料,分析了喷施不同浓度的GA3、NAA、乙烯利、6-BA和AgNO3对蓖麻雌雄花率的影响。结果表明:100mg/LGA3有利于蓖麻雌花的形成,250mg/LGA3则有利于雄花的分化,前者表现为雌花率上升,后者表现为雌花率降低;NAA和6-BA使雌花率增加,出现了纯雌株;乙烯利有利于雄花的分化,一定浓度的乙烯利可使两性株雄性化;AgNO3促雄效果明显,使两性株雄花率增加,单雌株出现少量雄花;同时试验还获得少数花性特殊(如全雄、纯雌)的材料。本研究为蓖麻的性别逆转诱导、单雌材料的繁殖及性别分化研究提供参考。

针对存在汽温偏差的某660 MW四角切圆锅炉,采用数值模拟与试验方法研究了墙式燃尽风水平摆角以及风量偏置对烟温偏差及燃烧特性的影响。模拟结果与现场实际情况吻合较好。模拟结果表明,左右墙燃尽风均等垂直送入炉内时,左侧烟气温度高于右侧,存在明显烟温偏差,现场实际运行中也表明存在明显汽温偏差。燃尽风顺时针与主气流反切送入炉内减弱了烟气残余旋转,有利于减少左右侧烟温及汽温偏差、提高燃烧效率。增加左墙燃尽风风量、减少右墙燃尽风风量后,左右侧区域烟气流量均匀性得到改善,烟温及汽温偏差减小;下炉膛未燃尽碳、CO与燃尽风混合强度增强,其燃烧剧烈程度增加,提高了燃烧效率。在实际运行中,建议燃尽风与主气流反切送入炉内,或者适当增加左墙燃尽风开度,既可以降低烟温/汽温偏差,又可以提高燃烧经济性。

以陇亚13号为材料,探究水分胁迫下播种量+施肥量协同作用对胡麻生长、产量和收获指数(harvest index,HI)的影响。通过相关性分析,揭示灌区/旱区不同水分环境对胡麻产量构成、HI的关键性状因子影响特征。结果表明:水分胁迫影响灌区/旱区产量构成因子的形成规律,以改变胡麻生长发育指标为代价达到对极端环境的适应性。灌区/旱区产量与产量构成因子间正、负相关性不同,且旱区胡麻产量构成因子的正效应因子减少,负效应因子增加。相同水分条件下,播种量+施肥量协同作用对胡麻产量的提高有限,旱区HI较灌区受水分胁迫的影响更突出。灌区千粒重、株高对产量起主导促进作用,旱区无回归分析。灌区每株结果粒数、单株果数对HI起抑制作用,千粒重起促进作用;旱区单株果数对HI起主导抑制因子,说明水分胁迫对灌区/旱区胡麻的生长及产量形成的主效应因子有不同侧重点。

Sinomenine hydrochloride is generally produced from Caulis Sinomenii. At present, the purification process in industrial production suffers from large amount of solid waste, high solvent toxicity, and low sinomenine hydrochloride yield. In this study, a new purification process for sinomenine hydrochloride was proposed by using the extract obtained from acid extraction of Caulis Sinomenii as the starting *** process included the following steps: alkalization, extraction, water washing, acid–water stripping,drying, and crystallization. 1-Heptanol was used as the extractant. The distribution coefficients of sinomenine and sinomenine hydrochloride in 1-heptanol–water system were 27.4 and 0.0167, *** dissociation constants of sinomenine hydrochloride were 8.27 and 11.24, respectively. Process parameters of the new purification process were optimized with experimental design. The extractant1-heptanol and sinomenine hydrochloride in the crystallization mother solution can be recycled in the new process. The purity of the obtained sinomenine hydrochloride crystals exceeded 85%, and the yield was about 70%. Compared with current industrial processes, safer extractant, less solid waste, and higher sinomenine hydrochloride yield can be achieved using the new purification process of sinomenine hydrochloride provided in this study.
