查询词典 nitrate

Super hybrid rice Gangyou 527 was used to investigate the effects of three irrigation regimes(submerged irrigation, dry cultivation, the treatment W2 that damp irrigation before booting stage, shallow irrigation at booting stage, wetting-drying alternation irrigation from heading stage to mature stage) and different amounts of N application on photosynthetic rate, activities of nitrate reductase, glutamine synthetase, glutamate synthase, endopeptidase in flag leaves, bleeding intensity in basal internodes and grain yield during grain filling, and studied correlations among the photosynthesis, nitrogen metabolism enzyme activity and root vigor at this stage.
