我县几年来大量推广水稻磷肥沾秧根的经验证明,这是一项经济有效的增产措施。但是磷肥沾秧根的肥效随土壤类型和水稻品种而有显著的差异。就土壤而言,红壤性稻田磷肥沾秧根增产显著,冲积性稻田则不显著。就品种类型来说,单季晚稻沾秧根肥效高,早稻和双季晚稻则较低。为了探索在冲积性稻田中提高磷肥沾秧根效果的
In recent years, a large number of paddy rice in our county to promote seedling root experience shows that this is a cost-effective stimulation measures. However, the fertilizer efficiency of rooting with phosphate fertilizer significantly differed with soil types and rice varieties. In terms of soil, the red paddy field significantly increased the yield of phosphate-treated seedlings, and the alluvial paddy fields did not show significant effects. In terms of variety types, the single-season late rice seedling has high fertilizer efficiency, while the lower rice in early rice and double-season late rice. In order to explore the alluvial paddy field to improve the effect of phosphate fertilizer rooting
