1125肥药双效剂对冬小麦生长发育及产量的影响

Impact of double effect medicine without social effects of pollu tion on development and output of winter wheat

研究了 112 5植物保护剂在小麦拔节期、孕穗期、灌浆期喷施稀释 15 0×、30 0×、45 0×、6 0 0×、75 0×液后 ,对其生长发育的影响。结果表明 :112 5可增加小麦茎粗 ,促进叶绿素的合成 ,增加叶面积、延长叶片功能期 ,增加穗粒数、千粒重 ,提高灌浆速度 ,降低小麦白粉病的发病率 ,产量比对照增加 1.32 %～ 9.80 % ,以喷施 30 0×液处理的小麦产量最高 ,与对照的差异性达到了极显著水平 ,其次是喷施 45 0×液的处理 ,与对照的差异性达到了显著水平。

Influence of 1125 was studied on development of wint er wheat after the wheat was sprayed 150×?300×?450×?600×?750×solutions in the jointing, bootting and grain filling date. The results showed:1125 may in crease stem width of wheat, advance chlorophyll synthetic, increase leaf area, e xtend leaf function date, increase spike grains and the weight of a thousand see ds,raise the grain filling rate, reduce incidence of disease on the powdery mild ew of wheat. The wheat yield increased 1.32%～9.80% than that of CK. The yield w as the highest on the treatment of spraying 300× solution. The divergence chara cter of the treatment and CK achieved the extreme striking standard. The diverge nce character of the spraying 450× solution treatment and CK achieved the stri king standard.
