| 摘 要： | 根据水稻节水灌溉试验资料，分析了覆膜旱作水稻干物质与茎、叶、穗、粒干重积累变化特点，评述了Logistic方程描述覆膜旱作水稻干物质增长规律的适用性，建立了节水灌溉的覆膜旱作水稻干物质增长模型。该模型比Logistic模型更符合覆膜旱作节水条件下水稻干物质变化规律，相关系数和精度更高。

| Abstract: | The growth feature of dry matter and dry weight of stem, leaf, ear and rice grain in plastic film mulched dry land are investigated according to the field experiment data of water-saving irrigation.The suitability of Logistic equation is a nalyzed and the model for describing the dry matter growth is established. The practice shows that the model is reasonable and the calculation precision and inter relation coefficient are higher than that of Logistic equation. |
