比较南方稻区并存的旱育秧、板田育秧和水育秧3种主要育秧方式秧苗的形态、生理及抗逆性表明,旱育苗根系发达,生长健壮,活力高,吸收氮、磷、钾能力强;叶片宽大健挺,叶鞘粗短,分蘖到位率高;生理素质优良,干物质积累多,组织充实,碳、氮代谢协调,抗逆性加抗寒性、立苗能力和抗涝能力明显优于板田育秧和水育秧。
The morphological, physiological and stress-resistant characteristics of three main seedling transplanting methods in drought-tolerant seedling, paddy field seedling growing and watering seedling in the south of China showed that the drought-tolerant seedling has developed root system, strong growth, high vigor and strong ability of absorbing nitrogen, phosphorus and potassium The leaves were thick and strong, the leaf sheaths were short and the tillering rate was high. Physiological quality was good, dry matter accumulation was more, tissue was enriched, carbon and nitrogen metabolism were coordinated, stress resistance and cold resistance were better, Yu-Tian Yu-tai and water Yu Yang.
