通过小麦盆栽和原位处理秸秆还田试验,研究了外源菌剂H-1、R-1和T-1处理秸秆后对小麦形态、生理及产量的影响。施菌剂处理的小麦苗期各形态指标均高于对照,但差异不显著;施菌剂处理的小麦叶绿素含量和小麦根系活力均显著高于不施菌剂的处理。施菌剂处理的小麦分蘖数、千粒重显著高于其他处理,其中用H-1还田处理的千粒重最高;叶绿素在小麦各生育期变化明显;各处理小麦整个生育期内根系活力总变化趋势相同,幅度大小有所差异。
The effects of exogenous bacterial agents H-1, R-1 and T-1 on the morphology, physiology and yield of wheat were studied by wheat pot and in-situ straw returning experiments. The morphological indexes of wheat seedling treated with the fungicide were higher than those of the control, but the difference was not significant. The chlorophyll content and wheat root activity of the wheat treated with the fungicide were significantly higher than that of the non-applied fungicide. The tiller number and 1000-grain weight of wheat treated with the fungicide were significantly higher than those of the other treatments, of which the 1000-grain weight was the highest with H-1 treatment, and the chlorophyll varied significantly during the whole wheat growth stage. , The magnitude of the difference.
