噻吩磺隆与2，4-D异辛酯对小麦产量及品质的影响

为了更好地在小麦田应用除草剂，研究了噻吩磺隆与2，4-D异辛酯对小麦产量及品质的影响。结果表明：不同药剂处理对小麦产量影响不明显，喷施噻吩磺降＋2，4-D异辛酯有效成份用量为53．48和225．00g·hm^-2的处理产量最高，为6875．0kg·hm^-2。只喷施噻吩磺隆的处理，小麦籽粒蛋白质含量和沉降值含量降低，淀粉含量增加；只喷施2，4-D异辛酯的处理，小麦籽粒的蛋白质含量、湿面筋含量和沉降值增加；噻吩磺隆与2，4-D异辛酯混用处理，小麦籽粒蛋白质含量、湿面筋含量和沉降值含量增加。

Effect of Thifensulfuron-methyl and Isooctyl 2, 4-dichlorophenoxyacetate on Wheat Yield and Quality

In order to study the effect of spraying Thifensulfuron-methyl and Isooctyl 2,4-dichlorophenoxyace- tate on yield and quality of wheat. Through spraying different concentrations of Thifensulfuron-methyl and Isooctyl 2,4-dichlorophenoxyacetate, the yield, yield traits, agronomic characters and quality index were meas- ured. The results showed that different medicament treatments had no significant effect on the yield,the highest yield occurred in the treatment of Thifensulfuron-methyl 53. 48 g. hm-z ＋ 2,4-diehlorophenoxyacetate 225.00 g, hm-2 was 6 875.0 kg. hm2. Grain protein content and sedimentation value of treatments spraying Thifensulfuron-methyl de- creased compared with CK, starch content increased. Grain protein content, wet gluten and sedimentation value of treatments spraying Isooetyl 2,4-diehlorophenoxyacetate increased compared with CK. Grain protein content, wet glu- ten and sedimentation value of treatments spraying Thifensulfuron-methyl and Isooetyl 2,4-dichlorophenoxyacetate in- creased compared with CK.
