籼稻、粳稻是普通栽培稻的两个亚种。粳稻一般耐寒性较强、抗白叶枯病、耐肥抗倒、叶片坚实、不易早衰、不易落粒、谷粒圆、出米率高、直链淀粉含量低,通常适宜在冷凉的气候条件下栽培。籼稻通常适宜炎热的气候,一般表现出耐热、抗稻瘟、省肥易倒、易落粒、谷粒长、直链淀粉含量高等特点。可见籼粳稻各有其优缺点,各有其适宜的生态条件。
Indica and japonica are two subspecies of common cultivated rice. Japonica rice is generally cold hardy, resistant to bacterial leaf blight, resistant to lodging, leaf stubble, not easy to premature aging, not easy to drop, grain round, a high rate of rice, low amylose content, usually suitable for cold climate Conditions of cultivation. Indica rice is usually suitable for hot climate, generally showing heat resistance, resistance to rice blast, fertilizer easy to fall, easy to drop, long grain, high amylose content. Visible indica japonica has its own advantages and disadvantages, each with its own suitable ecological conditions.
