水稻岩棉育苗的生长及生理特性研究

Study on Growth And Physiological Characteristics of Rice Seedling beared With Rock-Wool

本文探讨了以岩棉为基质，以育苗专用肥为养分给源的水稻育苗技术所培育的秧苗在生长、形态及生理素质方面的特点。研究表明，利用岩棉进行水稻育苗，有利于秧苗地下部的生长，可以育出符合壮苗标准的秧苗，岩棉育苗的秧苗素质优于软盘育苗，从而提高了秧苗的抗性和发根能力，为移栽后早生快发打下了坚实的基础。

This paper analyzed the property of rice seedling that was cultivated with a new technique of rock-wool seedling combining with proportional nutrients. The results showed that rock-wool seedling made not only root growth better but increased the content of bound water and soluble sugar, and photosynthesis, so its seedling quality was better than soft plate seedling' s, which laid solid foundations for rapid growth and tiller after transplanting.
