潴育和潜育型稻田根系生长情况及土壤肥力的动态变化

The rice roots and the soil fertility dynamic change of the periodicol water-logging and the gleyed type

与潜育型稻田相比,潴育型稻田白根多黄根少,无黑根;潴育型稻田全量养分含量低,速效养分变化大。

Compared to the gleyed type rice, the periodical water-logging has much white root, little yellow root, no black root, the periodical water-logging rice long-term fertility's content is low, short-tern fertility's chanage is fast.
