| 摘 要： | 为构建木薯茎叶生物量的估测模型,调查了木薯上、中、下部的茎粗、株高、叶柄长等形态学指标与茎叶生物量的关系.结果表明,木薯茎叶生物量主要受下部茎粗和株高的综合影响,并且下部茎粗、株高与茎叶生物量的关系均为乘幂函数关系.通过模型拟合和择优得到木薯茎叶生物量的估测模型W=0.032 83d2.48 6h0.1824.经新的实测数据检验,理论值与实测值的相对误差率为4.46%,完全满足测量精度要求.

| Abstract: | Morphological indexes such as stem diameter, plant height, petiole length in upper, middle and lower parts of cassava were measured and their relationship with the stem and leaf biomass were analyzed. Analysis showed that the stem and leaf biomass was mostly affected by the stem diameter and plant height in the lower part, and that the relationships between the stem diameter and plant height in the lower part and the stem and leaf biomass were expressed by a power function, based on which an estimating mode... |
