理想的株型,可以保证从空间结构上来提高光能利用率;而良好的光合特性,则是获得高产的生理基础。只有将两者有机地结合起来,才能获得较高的产量。 为了研究不同株型水稻品种的光合特性,1978年以中秆直立型、中秆较直立型及高秆披散型共5个品种做为试验材料,其中以当地农家品种“小白粘”为对照。现将试验结果报告如下:
The ideal plant type can ensure the utilization of light energy from the space structure; and the good photosynthetic characteristics are the physiological basis for obtaining high yield. Only by combining the two organically, can we get a higher yield. In order to study the photosynthetic characteristics of different rice varieties, five cultivars with upright stems, middle stems upright and tall stems were used as experimental materials in 1978, among which the local farmhouse variety “Small white sticky” was used as control . The test results are reported as follows:
