The results of comparative studies on ecological effects of upland and paddy beds and its physiobiochemical effects on rice seedling growth showed:the upland seedling bed has such ecological advantages as rapid raising of soil and air temperature,great difference of daily maximum and minimum temperature,high light penetratiom ratio and so on.

通过对早稻旱育苗床与水育苗床生态效应及其对早稻秧苗产生的生理效应的比较，表明水稻旱育苗床具有升温快，温度日较差大，薄膜内透光率高等生态优势；旱育苗床培育的秧苗具有种谷胚乳转化效率高，秧苗发根力强，ＳＯＤ酶活性高，电解质外渗率低，抗寒力强等生理优势。
