The Effect of Cultivation Techniques on Plant Type in View of the High Yield Result Induced by TFS Cultivation Method in Paddy Rice

Jiang Pengyan Feng Laiding (Zhejiang Academy of Agricultural Sciences)Yao Changxi (China National Rice Research Institute)  
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 morphologi- cal 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 coeffi- cient and the stereo distribution of stems and leaves in plant population.
