- 摘要:
- 采用二因素五水平二次正交旋转组合设计, 通过田间试验, 以杂草防效和玉米产量为目标函数, 对二氯喹啉酸、苯达松的二元混用效应及玉米田施用的最佳配方进行了初步探讨。结果表明,二氯喹啉酸、苯达松混用具有显著增效作用;玉米田施用的最佳配方为:二氯喹啉酸(903g.ai.hm-2)+苯达松(918.15 g.ai.hm-2);最佳配方范围为:二氯喹啉酸(723 ~ 1031 g.ai.hm-2)+苯达松(758 ~ 888 g.ai.hm-2)。
- Abstract:
- Field t rial w as conducted .Using methods of ro tational reg ression design and making cont roleff icacy and yield of corn as goal function , w e studied joint action and prescript ion adjustment of theherbicide mix ture .The result showed that there w as synergism between quinclorac and bentazon .Itw as concluded that the best dosage of above two herbicides w as quinclorac(903g.ai.ha-2), bentazon(918 .15g.ai.ha-2), and the best ranges w ere quinclo rac(723 ~ 1031g.ai.ha-2)plus bentazon (758 ~888g.ai.ha-2).
