[Pot experiment on effect of clipping at seedling stage on spring wheat].
Pot experiment on the compensatory effects of spring wheat(Triticum aestivum) at different clipping intensities (simulating herbivory) at seedling stage (three leaves) was conducted in semiarid region of Gansu Province. Under two conditions of 60% and 90% of field water-holding capacity, spring wheat growth was stimulated by clipping at seedling stage, resulting in overcompensation in biological and economic yields, and with more compensation for heavy clipping than light clipping. The overcompensation of the spring wheat was at the cost of more water consumption.
