沸石基质对水稻秧苗素质的影响

Effect of Zeolite Substrates on Qualities of Rice Seedling

试验以辽粳101为材料,对沸石、珍珠岩、蛭石、营养土四种育秧基质对水稻机插秧苗素质的影响进行了比较研究。结果表明:沸石基质培育的秧苗叶龄、株高适宜,叶绿素含量高,不定根数多,最长根长大,地上干重和根干重大,符合机插秧对秧苗的要求,沸石基质是理想的育秧基质。

Liaojingl01 was taken as experimental material to study effect of four substrates （zeolite, perlite, vermiculite and nutritive soil）on the quality of mechanical transplanting rice seedling. Results showed that seedlings grown in zeolite had more suitable leaf stage and height, higher cllorophyll, more and longer roots and higher dry weight of both above-ground parts and roots, which indicated that zeolite was the optimal substrates for growing mechanical transplanting rice seedling.
