在春玉米3～5叶期,一年生禾本科杂草3～5叶期,阔叶杂草2～4叶期,用有效成份为450～600 g a.i./hm2的20%嗪.烟.莠去津油悬浮剂(OF)进行茎叶均匀喷雾,施药后玉米出现短期褪绿、触杀性药害症状,但对玉米的成熟期及产量无不良影响,平均增产...在春玉米3～5叶期,一年生禾本科杂草3～5叶期,阔叶杂草2～4叶期,用有效成份为450～600 g a.i./hm2的20%嗪.烟.莠去津油悬浮剂(OF)进行茎叶均匀喷雾,施药后玉米出现短期褪绿、触杀性药害症状,但对玉米的成熟期及产量无不良影响,平均增产18%以上,在试验剂量范围内安全性很好,施药后30d对杂草的总株防效及鲜重防效均大于95%。展开更多
The title compound (C6N3H18)2Ti4O4(C2O4)74H2O 1 (C13H22N3O18Ti2, Mr = 604.14) was synthesized by the reaction of Ti(SO4)2, H2C2O42H2O and N-(2-ammonioethyl)- piperazinium (AEPP) in aqueous solution.

The single-crystal X-ray analysis has revealed that 1 crystallizes in the triclinic system, space group Pi with a = 9.1437(6), b = 11.4991(10), c = 11.6975(8) ? a = 96.2915(18), ?= 107.998(3), ? = 104.276(4), V = 1110.35(14) ?, Z = 2, Dc = 1.807 g/cm3, F(000) = 618, ?= 0.815 mm-1, the final R = 0.0463 and wR = 0.1264 for 3718 observed reflections with I > 2s(I). X-ray crystal-structure analysis suggests that compound 1 consists of [Ti4O4(C2O4)7]6- anion and two protonated N-(2-ammonioethyl)piperazinium cations. The anions are linked into an infinite chain through Ti4O4(C2O4)8 by sharing the oxalates as bridging ligands.展开更多
