本文研究和比较了大粒稻和小粒稻在植物学性状和谷物生产效率的生物学特性以及谷粒产量构成因素等经济性状方面的差异.小粒稻具有株矮,茎硬,分蘖力强、有效穗多和结实率高等优点,产量比大粒稻高12.6%.
In this paper, we compared and studied the biological characteristics of large-grain and small-grain rice in terms of the biological characteristics such as botanical traits and grain productivity as well as the economic traits such as grain yield components, etc. Small grain rice has the characters of short plant, hard stem, strong tillering ability, More and the high rate of fruiting, the yield is 12.6% higher than that of large grain rice.
