比较研究不同季节汕优63和金优77两种不同基因型水稻幼苗在东湖水中生长时对各磷形态的摄取规律。结果表明,汕优63在春末夏初时对DOP及PP的利用较多,但在夏末秋初时只对DOP的利用较多,而金优77在两个季节对PP的利用都不明显。
The uptake patterns of various phosphorus forms of two different genotypes of Shanyou 63 and Jinyou 77 in different seasons in East Lake water were compared. The results showed that Shanyou 63 used more DOP and PP at the beginning of spring and early summer, but only utilized more DOP in late summer and early autumn, while Jinyou 77 did not make any significant use of PP in both seasons.
