摘要
以日光温室膜下滴灌甜瓜为试验材料,研究了甜瓜叶片叶面积动态变化规律以及不同水分处理对甜瓜叶面积大小分布范围的影响。结果表明:①不同水分处理对甜瓜叶片扩展和叶面积大小产生了显著影响,以2 d为灌溉周期,蒸发皿系数(Kcp)采用0.6有利于甜瓜叶片扩展,而且平均叶片叶面积最大;②甜瓜叶片叶面积扩展动态变化符合指数多项式增长模型,该模型拟合结果与实测值较为吻合,且相关系数较高,符合日光温室膜下滴灌甜瓜叶片叶面积动态变化规律。
With the experiment materials of drip-irrigated muskmelon under mulch film in greenhouse, dynamic change law of leaf ar ea and the influence of different water treatment on distributing range of leaf size are studied in this paper. The results show that： （1） the leaf size of muskmelon was influenced remarkably by different water treatments. Under the condition of the interval of 2 days, keeping the plant-pan coefficient （Kcp）as 0.6 not only is of advantage to the development of leaf, but also can obtain the maximal average single leaf area; （2）Dynamic leaf development of muskmelon can be simulated by a exponential model. The model has a better pertinence and is accorded with the actual dynamic leaf development.
