Abstract: Basing on the data of plant types in our studies on“TFS”cultivation method, it was evealed that the fine cultivation technique played a great role on the building up of ideal plant type”in rice, and“TFSr”cultivation method unlike common cultivation tech- iques greatly reformed the four major cultivation joints of rice, namely raising of rice seedling, planting closely, spreading of fertilizer and irrigating,hence a few morphological features of rice(plant type)were effectively improved and the later were closely related to the photosynthetic efficiency in rice population. The analysis of the effect of “TFS”cultivation method on the plant type proved that through the improvement of cultivation technique, the following contents of the plant type may be advanced:the plant height and its distribution into each internode of rice,the angles between main stems and its tillers,the angles between stems and leaves, the thickness and life-span of green leaves in the formation duration of yield, the relationship between the extinction coefficient and the stereo distribution of stems and leaves in plant population.

Key words: TFS cultivation method, plant type, cultivation technique, crop population

摘要： 本文整理了我们在开展“稀少平”栽培法的研究中有关株型方面的部分资料,阐明了优良的栽培技术对于水稻“理想株型”的建成有重要作用。指出水稻“稀少平”栽培法由于在育秧、密植、施肥和灌水四个主要栽培环节上对原来的技术进行了较大的改革,因此有效地改善了与水稻群体的光合效率有密切关系的几个形态特性——株型。本文从分析稀少平栽培法与株型的关系入手,论证了下列几方面的株型内容是可以通过改进栽培技术予以改善的:水稻的植株高度及其在各节间的分配,茎蘖间的角度及叶片与茎秆的夹角,产量形成期的绿叶厚度与寿命,消光系数——群体茎叶的立体分布。最后,分析了“株型栽培”的概念,认为随着高产稻作的发展,“株型栽培”必将与“株型育种”相结合,以进一步提高水稻的产量能力。
