论水稻的高产形态

水稻品种的生产潜力与水稻的形态、生态、生理特性密切相关,本文论述了矮秆在水稻高产和抗倒中的作用;直立较厚、短而宽的叶片有利于光合作用和形成大穗,从而促进水稻高产;分蘖力强分蘖紧凑有利于增加穗数,提高产量;提高粳稻品种的谷草比,就会进一步提高品种的生产潜力;穗部性状中穗大小、粒大小、着粒疏密及结实率高低都会对水稻的产量产生影响。

Discuss on High-Yielding Morphology of Rice

The productive potential of rice variety is closely related to morphology,ecology and physiology.This article deals with some questions which dwarf straw is beneficial to high yield and lodging resistance of rice;erect,thick,short and wide leaf is helpful to photosynthesis and large panicle formation,thus increasing the yield;strong tillering capacity is helpful to increase panicles and yield;high grain/straw ratio can improve productive potential of variety;size of panicle and grain,grain density and seed setting rate can effect the yield.
