摘  要：
为研究新型生物助剂对我国大豆、玉米田除草剂常用剂型(水剂、乳油、悬浮剂)的作用效果,以非离子表面活性剂、甲酯化植物油、有机硅助剂为对照,通过田间试验的方法,调查评价不同剂型除草剂添加新型生物助剂对大豆、玉米田禾本科杂草和阔叶杂草防除效果的影响.结果表明:新型生物助剂能够使除草剂水剂对杂草的株防效提高22.82%~31.62%,鲜质量防效提高21.97%~32.30%;除草剂乳油株防效提高19.31%~31.27%,鲜质量防效提高20.71%~32.13%;除草剂悬浮剂株防效提高21.14%~36.11%,鲜质量防效提高21.58%~38.17%.新型生物助剂对悬浮剂的增效作用最明显,其次是水剂和乳油.新型生物助剂能够显著提高除草剂水剂、乳油、悬浮剂的生物活性,增效作用优于甲酯化植物油、有机硅助剂和非离子表面活性剂,并对作物安全.

摘  要：
In order to study the effects of new biological adjuvants on water aqua, emulsifiable concentrate and suspending agent of herbicides commonly used in soybean and maize fields in China, field experiments were conducted with nonionic surfactants, methyl esterified vegetable oils and organosilicon adjuvants as controls.The effects of different herbicides with new biological adjuvants on the control of grassy weeds and broad-leaved weeds were investigated and evaluated. The results showed that the new biological adjuvants could improve the control effect of herbicide water aqua on weeds by 22.82%-31.62%, fresh quality by 21.97%-32.30%, control effect of herbicide emulsifiable concentrate by 19.31%-31.27%, fresh quality by 20.71%-32.13%, control effect of herbicide suspending agent by 21.14%-36.11%, and fresh quality by 21.58%-38.17%. The synergistic effect of new biological adjuvants on suspending agent was the most obvious, followed by water aqua and emulsifiable concentrate. New biological adjuvants could significantly improve the biological activity of herbicide water aqua, emulsifiable concentrate and suspending agent. Its synergistic effect is better than methyl esterified vegetable oils,organosilicon adjuvants and nonionic surfactants, and it is safe for crops.
