查询词典 biomass

We classified the forest fuel and studied the fuel spatial distribution based on forest inventory and sample plots. Vertical and horizontal distribution of fuel is calculated from sample plots and tree biomass equation. Based on fuel distribution, wind simulation and DEM, fire intensity and effective shaded fuelbreak width are calculated under the condition of crown fire occurrence.

The leaf WUE of millet was increased when root cutting in seedling stage,and only the treatment of I2D of maize increased the leaf WUE; The biomass WUE of millet and maize were increased excepting the root cutting treatments of "TM" and "sl"; At the 80% field capacity, when the root was cutted more seriously and more later,the seed yield WUE of millet were dropped; While at the 50% field capacity, the seed yield WUE of millet was increased when the root cutting is moderate in prophase,and have no reduction of output or increase the production at the same time ,while the benefit of saving water didnt evidently at the later stage root cutting.

苗期伤根处理能够提高谷子叶片WUE，而玉米伤根后仅I2D处理的单叶WUE高于对照；除TM和sl处理外，伤根处理提高了谷子和玉米生物量WUE；在土壤含水量为80%田间持水量时，随着伤根程度的加剧和伤根时间的后移，谷子子粒产量WUE下降，伤根不利于谷子WUE的提高；而在50%田间持水量时，前期伤根量适度的处理在不减产甚至增产的情况下还有助于作物子粒产量WUE的提高，而后期伤根的节水效果并不明显。
