[Method] The synergistic test of green orange peel oil on 10% cyanoflurate SC and 10% metamifop EC was conducted in 2019.[Result] The control effect of green orange peel oil 150 mL/hm^(2)+ 10% cyanoflurate SC 1 275 mL/hm^(2) on Echinochloa crusgalli and Leptochloa chinensis were significantly superior to that of 10% cyanoflurate SC 1 500 mL/hm^(2). The control effects of green orange peel oil 150 m L/hm^(2)+10%cyanoflurate SC 1 200 m L/hm^(2) on E. crusgalli and L. chinensis was equivalent to that of 10% cyanoflurate SC 1 500 mL/hm^(2). The control effect of green orange peel oil 150 mL/hm^(2)+ 10% metamifop EC 1 275 mL/hm^(2) on E. crusgalli and L. chinensis was equivalent to that of 10% metamifop EC 1 500 m L/hm^(2). [Conclusion] The green orange peel oil had certain synergistic effect on cyanoflurate and metamifop.展开更多
高粱田的阔叶杂草对除草剂的抗性日趋严重,而能够用于高粱田的除草剂品种有限,导致阔叶杂草的防除比较困难,高粱的产量也受到了巨大影响。因此,生产中迫切需要筛选出对抗性阔叶杂草防效较好的除草剂。试验探讨了不同剂量20%苯嘧磺草胺...高粱田的阔叶杂草对除草剂的抗性日趋严重,而能够用于高粱田的除草剂品种有限,导致阔叶杂草的防除比较困难,高粱的产量也受到了巨大影响。因此,生产中迫切需要筛选出对抗性阔叶杂草防效较好的除草剂。试验探讨了不同剂量20%苯嘧磺草胺悬浮剂对高粱田阔叶杂草苯氏蓼、反枝苋和藜的防效。结果表明,中高剂量(60、90 g a.i./hm^(2))20%苯嘧磺草胺悬浮剂对高粱田阔叶杂草防除效果较好,对阔叶杂草的鲜重防效最高可达97.75%,持效期可达30 d左右,并且对高粱安全,不影响产量,具有减施增效的特点。该试验结果能够为高粱田阔叶杂草的合理防除提供理论依据。展开更多

Our objective was to collect data on genotype and phenotype for 60 leaf samples at four developmental stages, from three plant architectural positions and for three cultivars that were grown in two locations. Association mapping was conducted to detect genetic variants at quantitative trait SNP(QTS) loci, quantitative trait transcript(QTT) differences,quantitative trait protein(QTP) variability, and quantitative trait metabolite(QTM) changes,which can be summarized as QTX locus variation. The total heritabilities of the four-omics loci for both traits tested were 23.60% for epistasis and 15.26% for treatment interaction.Epistasis and environment × treatment interaction had important impacts on complex traits at all-omics levels. For decreasing chromium content and increasing total sugar in tobacco leaf, six methylated loci can be directly used for marker-assisted selection, and expression of ten QTTs, seven QTPs and six QTMs can be modified by selection or cultivation.展开更多
